NAME Net::Twitter::Lite - A perl interface to the Twitter API VERSION This document describes Net::Twitter::Lite version 0.10004 SYNOPSIS use Net::Twitter::Lite; my $nt = Net::Twitter::Lite->new( username => $user, password => $password ); my $result = eval { $nt->update('Hello, world!') }; eval { my $statuses = $nt->friends_timeline({ since_id => $high_water, count => 100 }); for my $status ( @$statuses ) { print "$status->{created_at} <$status->{user}{screen_name}> $status->{text}\n"; } }; warn "$@\n" if $@; DESCRIPTION This module provides a perl interface to the Twitter APIs. It uses the same API definitions as Net::Twitter, but without the extra bells and whistles and without the additional dependencies. Same great taste, less filling. This module is related to, but is not part of the "Net::Twitter" distribution. It's API methods and API method documentation are generated from "Net::Twitter"'s internals. It exists for those who cannot, or prefer not to install Moose and its dependencies. You should consider upgrading to "Net::Twitter" for additional functionality, finer grained control over features, full backwards compatibility with older versions of "Net::Twitter", and additional error handling options. CLIENT CODE CHANGES REQUIRED The default "apiurl" changed in version 0.08006. The change should be transparent to client code, unless you're using the "netrc" option. If so, you'll need to either update the ".netrc" entry and change the "machine" value from "twitter.com" to "api.twitter.com", or set either the "netrc" or "netrc_machine" options to "twitter.com". $nt = Net::Twitter::Lite->new(netrc_machine => 'twitter.com', netrc => 1); # -or- $nt = Net::Twitter::Lite->new(netrc => 'twitter.com'); IMPORTANT Beginning with version 0.03, it is necessary for web applications using OAuth authentication to pass the "callback" parameter to "get_authorization_url". In the absence of a callback parameter, when the user authorizes the application a PIN number is displayed rather than redirecting the user back to your site. MIGRATING FROM NET::TWITTER 2.x If you are migrating from Net::Twitter 2.12 (or an earlier version), you may need to make some minor changes to your application code in order to user Net::Twitter::Lite successfully. The primary difference is in error handling. Net::Twitter::Lite throws exceptions on error. It does not support the "get_error", "http_code", and "http_message" methods used in Net::Twitter 2.12 and prior versions. Instead of # DON'T! my $friends = $nt->friends(); if ( $friends ) { # process $friends } wrap the API call in an eval block: # DO! my $friends = eval { $nt->friends() }; if ( $friends ) { # process $friends } Here's a much more complex example taken from application code using Net::Twitter 2.12: # DON'T! my $friends = $nt->friends(); if ( $friends ) { # process $friends } else { my $error = $nt->get_error; if ( ref $error ) { if ( ref($error) eq 'HASH' && exists $error->{error} ) { $error = $error->{error}; } else { $error = 'Unexpected error type ' . ref($error); } } else { $error = $nt->http_code() . ": " . $nt->http_message; } warn "$error\n"; } The Net::Twitter::Lite equivalent is: # DO! eval { my $friends = $nt->friends(); # process $friends }; warn "$@\n" if $@; return; In Net::Twitter::Lite, an error can always be treated as a string. See Net::Twitter::Lite::Error. The HTTP Status Code and HTTP Message are both available. Rather than accessing them via the Net::Twitter::Lite instance, you access them via the Net::Twitter::Lite::Error instance thrown as an error. For example: # DO! eval { my $friends = $nt->friends(); # process $friends }; if ( my $error = $@ ) { if ( blessed $error && $error->isa("Net::Twitter::Lite::Error) && $error->code() == 502 ) { $error = "Fail Whale!"; } warn "$error\n"; } Unsupported Net::Twitter 2.12 options to "new" Net::Twitter::Lite does not support the following Net::Twitter 2.12 options to "new". It silently ignores them: no_fallback If Net::Twitter::Lite is unable to create an instance of the class specified in the "useragent_class" option to "new", it dies, rather than falling back to an LWP::UserAgent object. You really don't want a failure to create the "useragent_class" you specified to go unnoticed. twittervision Net::Twitter::Lite does not support the TwitterVision API. Use Net::Twitter, instead, if you need it. skip_arg_validation Net::Twitter::Lite does not API parameter validation. This is a feature. If Twitter adds a new option to an API method, you can use it immediately by passing it in the HASH ref to the API call. Net::Twitter::Lite relies on Twitter to validate its own parameters. An appropriate exception will be thrown if Twitter reports a parameter error. die_on_validation See "skip_arg_validation". If Twitter returns an bad parameter error, an appropriate exception will be thrown. arrayref_on_error This option allowed the following idiom in Net::Twitter 2.12: # DON'T! for my $friend ( @{ $nt->friends() } ) { # process $friend } The equivalent Net::Twitter::Lite code is: # DO! eval { for my $friend ( @{ $nt->friends() } ) { # process $friend } }; Unsupported Net::Twitter 2.12 methods clone The "clone" method was added to Net::Twitter 2.x to allow safe error handling in an environment where concurrent requests are handled, for example, when using LWP::UserAgent::POE as the "useragent_class". Since Net::Twitter::Lite throws exceptions instead of stashing them in the Net::Twitter::Lite instance, it is safe in a current request environment, obviating the need for "clone". get_error http_code http_message These methods are replaced by Net::Twitter::Lite::Error. An instance of that class is thrown errors are encountered. METHODS AND ARGUMENTS new This constructs a "Net::Twitter::Lite" object. It takes several named parameters, all of them optional: username This is the screen name or email used to authenticate with Twitter. Use this option for Basic Authentication, only. password This is the password used to authenticate with Twitter. Use this option for Basic Authentication, only. consumer_key A string containing the OAuth consumer key provided by Twitter when an application is registered. Use this option for OAuth authentication, only. consumer_secret A string containing the OAuth consumer secret. Use this option for OAuth authentication, only. the "OAuth" trait is included. oauth_urls A HASH ref of URLs to be used with OAuth authentication. Defaults to: { request_token_url => "http://twitter.com/oauth/request_token", authorization_url => "http://twitter.com/oauth/authorize", access_token_url => "http://twitter.com/oauth/access_token", xauth_url => "https://twitter.com/oauth/access_token", } clientname The value for the "X-Twitter-Client-Name" HTTP header. It defaults to "Perl Net::Twitter::Lite". clientver The value for the "X-Twitter-Client-Version" HTTP header. It defaults to current version of the "Net::Twitter::Lite" module. clienturl The value for the "X-Twitter-Client-URL" HTTP header. It defaults to the search.cpan.org page for the "Net::Twitter::Lite" distribution. useragent_class The "LWP::UserAgent" compatible class used internally by "Net::Twitter::Lite". It defaults to "LWP::UserAgent". For POE based applications, consider using "LWP::UserAgent::POE". useragent_args An HASH ref of arguments to pass to constructor of the class specified with "useragent_class", above. It defaults to {} (an empty HASH ref). useragent The value for "User-Agent" HTTP header. It defaults to "Net::Twitter::Lite/0.10004 (Perl)". source The value used in the "source" parameter of API method calls. It is currently only used in the "update" method in the REST API. It defaults to "twitterpm". This results in the text "from Net::Twitter" rather than "from web" for status messages posted from "Net::Twitter::Lite" when displayed via the Twitter web interface. The value for this parameter is provided by Twitter when a Twitter application is registered. See . apiurl The URL for the Twitter API. This defaults to "http://twitter.com". identica If set to 1 (or any value that evaluates to true), apiurl defaults to "http://identi.ca/api". ssl If set to 1, an SSL connection will be used for all API calls. Defaults to 0. netrc (Optional) Sets the *machine* key to look up in ".netrc" to obtain credentials. If set to 1, Net::Twitter::Lite will use the value of the "netrc_machine" option (below). # in .netrc machine api.twitter.com login YOUR_TWITTER_USER_NAME password YOUR_TWITTER_PASSWORD machine semifor.twitter.com login semifor password SUPERSECRET # in your perl program $nt = Net::Twitter::Lite->new(netrc => 1); $nt = Net::Twitter::Lite->new(netrc => 'semifor.twitter.com'); netrc_machine (Optional) Sets the "machine" entry to look up in ".netrc" when "> is used. Defaults to "api.twitter.com". BASIC AUTHENTICATION METHODS credentials($username, $password) Set the credentials for Basic Authentication. This is helpful for managing multiple accounts. OAUTH METHODS authorized Whether the client has the necessary credentials to be authorized. Note that the credentials may be wrong and so the request may fail. request_access_token Returns list including the access token, access token secret, user_id, and screen_name for this user. Takes a HASH of arguments. The "verifier" argument is required. See "OAUTH EXAMPLES". The user must have authorized this app at the url given by "get_authorization_url" first. For desktop applications, the Twitter authorization page will present the user with a PIN number. Prompt the user for the PIN number, and pass it as the "verifier" argument to request_access_token. Returns the access token and access token secret but also sets them internally so that after calling this method, you can immediately call API methods requiring authentication. get_authorization_url(callback => $callback_url) Get the URL used to authorize the user. Returns a "URI" object. For web applications, pass your applications callback URL as the "callback" parameter. No arguments are required for desktop applications ("callback" defaults to "oob", out-of-band). get_authentication_url(callback => $callback_url) Get the URL used to authenticate the user with "Sign in with Twitter" authentication flow. Returns a "URI" object. For web applications, pass your applications callback URL as the "callback" parameter. No arguments are required for desktop applications ("callback" defaults to "oob", out-of-band). xauth($username, $password) Exchanges a username and password for OAuth tokens. Your application must be approved for XAuth access by Twitter for this method to work. Twitter does not grant XAuth access for web applications except for a brief period of time to allow them to switch form Basic authentication to OAuth authentication. access_token Get or set the access token. access_token_secret Get or set the access token secret. request_token Get or set the request token. request_token_secret Get or set the request token secret. access_token_url Get or set the access_token URL. authentication_url Get or set the authentication URL. authorization_url Get or set the authorization URL. request_token_url Get or set the request_token URL. xauth_url Get or set the XAuth access token request URL. API METHODS AND ARGUMENTS Most Twitter API methods take parameters. All Net::Twitter::Lite API methods will accept a HASH ref of named parameters as specified in the Twitter API documentation. For convenience, many Net::Twitter::Lite methods accept simple positional arguments as documented, below. The positional parameter passing style is optional; you can always use the named parameters in a hash ref if you prefer. For example, the REST API method "update" has one required parameter, "status". You can call "update" with a HASH ref argument: $nt->update({ status => 'Hello world!' }); Or, you can use the convenient form: $nt->update('Hello world!'); The "update" method also has an optional parameter, "in_reply_to_status_id". To use it, you must use the HASH ref form: $nt->update({ status => 'Hello world!', in_reply_to_status_id => $reply_to }); Convenience form is provided for the required parameters of all API methods. So, these two calls are equivalent: $nt->friendship_exists({ user_a => $fred, user_b => $barney }); $nt->friendship_exists($fred, $barney); Many API methods have aliases. You can use the API method name, or any of its aliases, as you prefer. For example, these calls are all equivalent: $nt->friendship_exists($fred, $barney); $nt->relationship_exists($fred, $barney); $nt->follows($fred, $barney); Aliases support both the HASH ref and convenient forms: $nt->follows({ user_a => $fred, user_b => $barney }); Methods that support the "page" parameter expect page numbers > 0. Twitter silently ignores invalid "page" values. So "{ page => 0 }" produces the same result as "{ page => 1 }". In addition to the arguments specified for each API method described below, an additional "authenticate" parameter can be passed. To request an "Authorization" header, pass "authenticated => 1"; to suppress an authentication header, pass "authentication => 0". Even if requested, an Authorization header will not be added if there are no user credentials (username and password for Basic Authentication; access tokens for OAuth). This is probably only useful for the "rate_limit_status" method in the REST API, since it returns different values for an authenticated and a non-authenticated call. REST API Methods Several of these methods accept a user ID as the "id" parameter. The user ID can be either a screen name, or the users numeric ID. To disambiguate, use the "screen_name" or "user_id" parameters, instead. For example, These calls are equivalent: $nt->create_friend('perl_api'); # screen name $nt->create_friend(1564061); # numeric ID $nt->create_friend({ id => 'perl_api' }); $nt->create_friend({ screen_name => 'perl_api' }); $nt->create_friend({ user_id => 1564061 }); However user_id 911 and screen_name 911 are separate Twitter accounts. These calls are NOT equivalent: $nt->create_friend(911); # interpreted as screen name $nt->create_friend({ user_id => 911 }); # screen name: richellis Whenever the "id" parameter is required and "user_id" and "screen_name" are also parameters, using any one of them satisfies the requirement. account_settings Parameters: *none* Required: *none* Returns the current trend, geo and sleep time information for the authenticating user.

Use this method to sign users out of client-facing applications like widgets. Returns: Error favorites Parameters: id, page, include_entities Required: *none* Returns the 20 most recent favorite statuses for the authenticating user or user specified by the ID parameter. Returns: ArrayRef[Status] followers Parameters: id, user_id, screen_name, cursor, include_entities Required: *none* Returns a reference to an array of the user's followers. If "id", "user_id", or "screen_name" is not specified, the followers of the authenticating user are returned. The returned users are ordered from most recently followed to least recently followed. Use the optional "cursor" parameter to retrieve users in pages of 100. When the "cursor" parameter is used, the return value is a reference to a hash with keys "previous_cursor", "next_cursor", and "users". The value of "users" is a reference to an array of the user's friends. The result set isn't guaranteed to be 100 every time as suspended users will be filtered out. Set the optional "cursor" parameter to -1 to get the first page of users. Set it to the prior return's value of "previous_cursor" or "next_cursor" to page forward or backwards. When there are no prior pages, the value of "previous_cursor" will be 0. When there are no subsequent pages, the value of "next_cursor" will be 0. Returns: HashRef|ArrayRef[User] followers_ids followers_ids(id) Parameters: id, user_id, screen_name, cursor Required: id Returns a reference to an array of numeric IDs for every user following the specified user.

When the "cursor" parameter is used, the return value is a reference to a hash with keys "previous_cursor", "next_cursor", and "ids". The value of "ids" is a reference to an array of IDS of the user's followers. Set the optional "cursor" parameter to -1 to get the first page of IDs. Set it to the prior return's value of "previous_cursor" or "next_cursor" to page forward or backwards. When there are no prior pages, the value of "previous_cursor" will be 0. When there are no subsequent pages, the value of "next_cursor" will be 0. Returns: HashRef|ArrayRef[Int] friends alias: following Parameters: id, user_id, screen_name, cursor, include_entities Required: *none* Returns a reference to an array of the user's friends. If "id", "user_id", or "screen_name" is not specified, the friends of the authenticating user are returned. The returned users are ordered from most recently followed to least recently followed. Use the optional "cursor" parameter to retrieve users in pages of 100. When the "cursor" parameter is used, the return value is a reference to a hash with keys "previous_cursor", "next_cursor", and "users". The value of "users" is a reference to an array of the user's friends. The result set isn't guaranteed to be 100 every time as suspended users will be filtered out. Set the optional "cursor" parameter to -1 to get the first page of users. Set it to the prior return's value of "previous_cursor" or "next_cursor" to page forward or backwards. When there are no prior pages, the value of "previous_cursor" will be 0. When there are no subsequent pages, the value of "next_cursor" will be 0. Returns: Hashref|ArrayRef[User] friends_ids friends_ids(id) alias: following_ids Parameters: id, user_id, screen_name, cursor Required: id Returns a reference to an array of numeric IDs for every user followed the specified user.

When there are no subsequent pages, the value of "next_cursor" will be 0. Returns: HashRef|ArrayRef[Int] friends_timeline alias: following_timeline Parameters: since_id, max_id, count, page, skip_user, trim_user, include_entities, include_rts Required: *none* Returns the 20 most recent statuses posted by the authenticating user and that user's friends. This is the equivalent of /home on the Web. Returns: ArrayRef[Status] friendship_exists friendship_exists(user_a, user_b) alias: relationship_exists alias: follows Parameters: user_a, user_b Required: user_a, user_b Tests for the existence of friendship between two users. Will return true if user_a follows user_b, otherwise will return false. Returns: Bool friendships_incoming friendships_incoming(cursor) Parameters: cursor Required: cursor Returns an HASH ref with an array of numeric IDs in the "ids" element for every user who has a pending request to follow the authenticating user. Returns: HashRef friendships_outgoing friendships_outgoing(cursor) Parameters: cursor Required: cursor Returns an HASH ref with an array of numeric IDs in the "ids" element for every protected user for whom the authenticating user has a pending follow request.

This is the equivalent of /timeline/home on the Web. Returns: ArrayRef[Status] lookup_friendships Parameters: user_id, screen_name Required: *none* Returns the relationship of the authenticating user to the comma separated list or ARRAY ref of up to 100 screen_names or user_ids provided. Values for connections can be: following, following_requested, followed_by, none. Requires authentication. Returns: ArrayRef lookup_users Parameters: user_id, screen_name, include_entities Required: *none* Return up to 20 users worth of extended information, specified by either ID, screen name, or combination of the two. The author's most recent status (if the authenticating user has permission) will be returned inline. This method is rate limited to 1000 calls per hour. This method will accept user IDs or screen names as either a comma delimited string, or as an ARRAY ref. It will also accept arguments in the normal HASHREF form or as a simple list of named arguments. I.e., any of the following forms are acceptable: $nt->lookup_users({ user_id => '1234,6543,3333' }); $nt->lookup_users(user_id => '1234,6543,3333'); $nt->lookup_users({ user_id => [ 1234, 6543, 3333 ] }); $nt->lookup_users({ screen_name => 'fred,barney,wilma' }); $nt->lookup_users(screen_name => ['fred', 'barney', 'wilma']); $nt->lookup_users( screen_name => ['fred', 'barney' ], user_id => '4321,6789', ); Returns: ArrayRef[User] mentions alias: replies Parameters: since_id, max_id, count, page, trim_user, include_rts, include_entities Required: *none* Returns the 20 most recent mentions (statuses containing @username) for the authenticating user. Returns: ArrayRef[Status] new_direct_message new_direct_message(user, text) Parameters: user, text, screen_name, user_id, include_entities Required: user, text Sends a new direct message to the specified user from the authenticating user. Requires both the user and text parameters. Returns the sent message when successful. In order to support numeric screen names, the "screen_name" or "user_id" parameters may be used instead of "user". Returns: DirectMessage no_retweet_ids Parameters: *none* Required: *none* Returns an ARRAY ref of user IDs for which the authenticating user does not want to receive retweets. Returns: ArrayRef[UserIDs] public_timeline Parameters: skip_user, trim_user, include_entities Required: *none* Returns the 20 most recent statuses from non-protected users who have set a custom user icon. Does not require authentication. Note that the public timeline is cached for 60 seconds so requesting it more often than that is a waste of resources. If user credentials are provided, "public_timeline" calls are authenticated, so they count against the authenticated user's rate limit. Use "->public_timeline({ authenticate => 0 })" to make an unauthenticated call which will count against the calling IP address' rate limit, instead. Returns: ArrayRef[Status] rate_limit_status Parameters: *none* Required: *none* Returns the remaining number of API requests available to the authenticated user before the API limit is reached for the current hour. Use "->rate_limit_status({ authenticate => 0 })" to force an unauthenticated call, which will return the status for the IP address rather than the authenticated user. (Note: for a web application, this is the server's IP address.) Returns: RateLimitStatus related_results related_results(id) Parameters: id Required: id If available, returns an array of replies and mentions related to the specified status. There is no guarantee there will be any replies or mentions in the response. This method is only available to users who have access to #newtwitter. Requires authentication. Returns: ArrayRef[Status] report_spam report_spam(id) Parameters: id, user_id, screen_name, include_entities Required: id The user specified in the id is blocked by the authenticated user and reported as a spammer. Returns: User retweet retweet(id) Parameters: id, include_entities, trim_user Required: id Retweets a tweet. Requires the id parameter of the tweet you are retweeting. Returns the original tweet with retweet details embedded. Returns: Status retweeted_by retweeted_by(id) Parameters: id, count, page, trim_user, include_entities Required: id Returns up to 100 users who retweeted the status identified by "id". Returns: ArrayRef[User] retweeted_by_ids retweeted_by_ids(id) Parameters: id, count, page, trim_user, include_entities Required: id Returns the IDs of up to 100 users who retweeted the status identified by "id". Returns: ArrayRef[User] retweeted_by_me Parameters: since_id, max_id, count, page, trim_user, include_entities Required: *none* Returns the 20 most recent retweets posted by the authenticating user. Returns: ArrayRef[Status] retweeted_by_user retweeted_by_user(id) Parameters: id, user_id, screen_name Required: id Returns the 20 most recent retweets posted by the specified user. The user is specified using the user_id or screen_name parameters. This method is identical to "retweeted_by_me" except you can choose the user to view. Does not require authentication, unless the user is protected. Returns: ArrayRef retweeted_to_me Parameters: since_id, max_id, count, page Required: *none* Returns the 20 most recent retweets posted by the authenticating user's friends. Returns: ArrayRef[Status] retweeted_to_user retweeted_to_user(id) Parameters: id, user_id, screen_name Required: id Returns the 20 most recent retweets posted by users the specified user follows. The user is specified using the user_id or screen_name parameters. This method is identical to "retweeted_to_me" except you can choose the user to view. Does not require authentication, unless the user is protected. Returns: ArrayRef retweets retweets(id) Parameters: id, count, trim_user, include_entities Required: id Returns up to 100 of the first retweets of a given tweet. Returns: Arrayref[Status] retweets_of_me alias: retweeted_of_me Parameters: since_id, max_id, count, page, trim_user, include_entities Required: *none* Returns the 20 most recent tweets of the authenticated user that have been retweeted by others. Returns: ArrayRef[Status] reverse_geocode reverse_geocode(lat, long) Parameters: lat, long, accuracy, granularity, max_results Required: lat, long Search for places (cities and neighborhoods) that can be attached to a statuses/update. Given a latitude and a longitude, return a list of all the valid places that can be used as a place_id when updating a status. Conceptually, a query can be made from the user's location, retrieve a list of places, have the user validate the location he or she is at, and then send the ID of this location up with a call to statuses/update. There are multiple granularities of places that can be returned -- "neighborhoods", "cities", etc. At this time, only United States data is available through this method. lat Required. The latitude to query about. Valid ranges are -90.0 to +90.0 (North is positive) inclusive. long Required. The longitude to query about. Valid ranges are -180.0 to +180.0 (East is positive) inclusive. accuracy Optional. A hint on the "region" in which to search. If a number, then this is a radius in meters, but it can also take a string that is suffixed with ft to specify feet. If this is not passed in, then it is assumed to be 0m. If coming from a device, in practice, this value is whatever accuracy the device has measuring its location (whether it be coming from a GPS, WiFi triangulation, etc.). granularity Optional. The minimal granularity of data to return. If this is not passed in, then "neighborhood" is assumed. "city" can also be passed. max_results Optional. A hint as to the number of results to return. This does not guarantee that the number of results returned will equal max_results, but instead informs how many "nearby" results to return. Ideally, only pass in the number of places you intend to display to the user here. Returns: HashRef saved_searches Parameters: *none* Required: *none* Returns the authenticated user's saved search queries. Returns: ArrayRef[SavedSearch] sent_direct_messages Parameters: since_id, max_id, page, count, include_entities Required: *none* Returns a list of the 20 most recent direct messages sent by the authenticating user including detailed information about the sending and recipient users. Returns: ArrayRef[DirectMessage] show_direct_message show_direct_message(id) Parameters: id, include_entities Required: id Returns a single direct message, specified by an id parameter. Like the "direct_messages" request, this method will include the user objects of the sender and recipient. Requires authentication.

Returns: SavedSearch show_status show_status(id) Parameters: id, trim_user, include_entities Required: id Returns a single status, specified by the id parameter. The status's author will be returned inline. Returns: Status show_user show_user(id) Parameters: id, screen_name, include_entities Required: id Returns extended information of a given user, specified by ID or screen name as per the required id parameter. This information includes design settings, so third party developers can theme their widgets according to a given user's preferences. You must be properly authenticated to request the page of a protected user. Returns: ExtendedUser suggestion_categories Parameters: *none* Required: *none* Returns the list of suggested user categories. The category slug can be used in the "user_suggestions" API method get the users in that category . Does not require authentication. Returns: ArrayRef test Parameters: *none* Required: *none* Returns the string "ok" status code. Returns: Str trends Parameters: *none* Required: *none* Returns the top ten queries that are currently trending on Twitter. The response includes the time of the request, the name of each trending topic, and the url to the Twitter Search results page for that topic. Returns: ArrayRef[Query] trends_available Parameters: lat, long Required: *none* Returns the locations with trending topic information. The response is an array of "locations" that encode the location's WOEID (a Yahoo! Where On Earth ID ) and some other human-readable information such as a the location's canonical name and country. When the optional "lat" and "long" parameters are passed, the available trend locations are sorted by distance from that location, nearest to farthest. Use the WOEID returned in the location object to query trends for a specific location. Returns: ArrayRef[Location] trends_current trends_current(exclude) Parameters: exclude Required: *none* Returns the current top ten trending topics on Twitter. The response includes the time of the request, the name of each trending topic, and query used on Twitter Search results page for that topic.

Returns: HashRef trends_location trends_location(woeid) Parameters: woeid Required: woeid Returns the top 10 trending topics for a specific location. The response is an array of "trend" objects that encode the name of the trending topic, the query parameter that can be used to search for the topic on Search, and the direct URL that can be issued against Search. This information is cached for five minutes, and therefore users are discouraged from querying these endpoints faster than once every five minutes. Global trends information is also available from this API by using a WOEID of 1. Returns: ArrayRef[Trend] trends_weekly Parameters: date, exclude Required: *none* Returns the top 30 trending topics for each day in a given week. Returns: HashRef update update(status) Parameters: status, lat, long, place_id, display_coordinates, in_reply_to_status_id, trim_user, include_entities Required: status Updates the authenticating user's status. Requires the status parameter specified. A status update with text identical to the authenticating user's current status will be ignored. status Required. The text of your status update. URL encode as necessary. Statuses over 140 characters will cause a 403 error to be returned from the API. in_reply_to_status_id Optional. The ID of an existing status that the update is in reply to. o Note: This parameter will be ignored unless the author of the tweet this parameter references is mentioned within the status text. Therefore, you must include @username, where username is the author of the referenced tweet, within the update. lat Optional. The location's latitude that this tweet refers to. The valid ranges for latitude is -90.0 to +90.0 (North is positive) inclusive. This parameter will be ignored if outside that range, if it is not a number, if geo_enabled is disabled, or if there not a corresponding long parameter with this tweet. long Optional. The location's longitude that this tweet refers to. The valid ranges for longitude is -180.0 to +180.0 (East is positive) inclusive. This parameter will be ignored if outside that range, if it is not a number, if geo_enabled is disabled, or if there not a corresponding lat parameter with this tweet. place_id Optional. The place to attach to this status update. Valid place_ids can be found by querying "reverse_geocode". display_coordinates Optional. By default, geo-tweets will have their coordinates exposed in the status object (to remain backwards compatible with existing API applications). To turn off the display of the precise latitude and longitude (but keep the contextual location information), pass "display_coordinates =" 0> on the status update.

The "image" parameter must be an arrayref with the same interpretation as the "image" parameter in the "update_profile_image" method. The "use" parameter allows you to specify whether to use the uploaded profile background or not. See that method's documentation for details. Returns: ExtendedUser update_profile_colors Parameters: profile_background_color, profile_text_color, profile_link_color, profile_sidebar_fill_color, profile_sidebar_border_color Required: *none* Sets one or more hex values that control the color scheme of the authenticating user's profile page on twitter.com. These values are also returned in the /users/show API method. Returns: ExtendedUser update_profile_image update_profile_image(image) Parameters: image Required: image Updates the authenticating user's profile image. The "image" parameter is an arrayref with the following interpretation: [ $file ] [ $file, $filename ] [ $file, $filename, Content_Type => $mime_type ] [ undef, $filename, Content_Type => $mime_type, Content => $raw_image_data ] The first value of the array ($file) is the name of a file to open. The second value ($filename) is the name given to Twitter for the file. If $filename is not provided, the basename portion of $file is used. If $mime_type is not provided, it will be provided automatically using LWP::MediaTypes::guess_media_type(). $raw_image_data can be provided, rather than opening a file, by passing "undef" as the first array value. Returns: ExtendedUser user_suggestions user_suggestions(category) alias: follow_suggestions Parameters: category, lang Required: category Access the users in a given category of the Twitter suggested user list and return their most recent status if they are not a protected user.

Returns: HashRef ERROR HANDLING When "Net::Twitter::Lite" encounters a Twitter API error or a network error, it throws a "Net::Twitter::Lite::Error" object. You can catch and process these exceptions by using "eval" blocks and testing $@: eval { my $statuses = $nt->friends_timeline(); # this might die! for my $status ( @$statuses ) { #... } }; if ( $@ ) { # friends_timeline encountered an error if ( blessed $@ && $@->isa('Net::Twitter::Lite::Error' ) { #... use the thrown error obj warn $@->error; } else { # something bad happened! die $@; } } "Net::Twitter::Lite::Error" stringifies to something reasonable, so if you don't need detailed error information, you can simply treat $@ as a string: eval { $nt->update($status) }; if ( $@ ) { warn "update failed because: $@\n"; } AUTHENTICATION Net::Twitter::Lite currently supports both Basic Authentication and OAuth. The choice of authentication strategies is determined by the options passed to "new" or the use of the "credentials" method. An error will be thrown if options for both strategies are provided. BASIC AUTHENTICATION To use Basic Authentication, pass the "username" and "password" options to "new", or call "credentials" to set them. When Basic Authentication is used, the "Authorization" header is set on each authenticated API call. OAUTH AUTHENTICATION To use OAuth authentication, pass the "consumer_key" and "consumer_secret" options to new. Net::OAuth::Simple must be installed in order to use OAuth and an error will be thrown if OAuth is attempted without it. Net::Twitter::Lite does not *require* Net::OAuth::Simple, making OAuth an optional feature. OAUTH EXAMPLES See the "examples" directory included in this distribution for full working examples using OAuth. Here's how to authorize users as a desktop app mode: use Net::Twitter::Lite; my $nt = Net::Twitter::Lite->new( consumer_key => "YOUR-CONSUMER-KEY", consumer_secret => "YOUR-CONSUMER-SECRET", ); # You'll save the token and secret in cookie, config file or session database my($access_token, $access_token_secret) = restore_tokens(); if ($access_token && $access_token_secret) { $nt->access_token($access_token); $nt->access_token_secret($access_token_secret); } unless ( $nt->authorized ) { # The client is not yet authorized: Do it now print "Authorize this app at ", $nt->get_authorization_url, " and enter the PIN#\n"; my $pin = ; # wait for input chomp $pin; my($access_token, $access_token_secret, $user_id, $screen_name) = $nt->request_access_token(verifier => $pin); save_tokens($access_token, $access_token_secret); # if necessary } # Everything's ready In a web application mode, you need to save the oauth_token and oauth_token_secret somewhere when you redirect the user to the OAuth authorization URL. sub twitter_authorize : Local { my($self, $c) = @_; my $nt = Net::Twitter::Lite->new(%param); my $url = $nt->get_authorization_url(callback => $callbackurl); $c->response->cookies->{oauth} = { value => { token => $nt->request_token, token_secret => $nt->request_token_secret, }, }; $c->response->redirect($url); } And when the user returns back, you'll reset those request token and secret to upgrade the request token to access token. sub twitter_auth_callback : Local { my($self, $c) = @_; my %cookie = $c->request->cookies->{oauth}->value; my $nt = Net::Twitter::Lite->new(%param); $nt->request_token($cookie{token}); $nt->request_token_secret($cookie{token_secret}); my $verifier = $c->req->param->{oauth_verifier}; my($access_token, $access_token_secret, $user_id, $screen_name) = $nt->request_access_token(verifier => $verifier); # Save $access_token and $access_token_secret in the database associated with $c->user } Later on, you can retrieve and reset those access token and secret before calling any Twitter API methods. sub make_tweet : Local { my($self, $c) = @_; my($access_token, $access_token_secret) = ...; my $nt = Net::Twitter::Lite->new(%param); $nt->access_token($access_token); $nt->access_token_secret($access_token_secret); # Now you can call any Net::Twitter::Lite API methods on $nt my $status = $c->req->param('status'); my $res = $nt->update({ status => $status }); } SEE ALSO Net::Twitter::Lite::Error The "Net::Twitter::Lite" exception object.
