Net::Twitter - A perl interface to the Twitter API
This document describes Net::Twitter version 3.11003
use Net::Twitter; my $nt = Net::Twitter->new( traits => [qw/API::REST/], username => $user, password => $password ); my $result = $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"; } }; if ( my $err = $@ ) { die $@ unless blessed $err && $err->isa('Net::Twitter::Error'); warn "HTTP Response Code: ", $err->code, "\n", "HTTP Message......: ", $err->message, "\n", "Twitter error.....: ", $err->error, "\n"; }
This module provides a perl interface to the Twitter APIs. See http://apiwiki.twitter.com/Twitter-API-Documentation for a full description of the Twitter APIs.
Net::Twitter is Moose based. Moose provides some advantages, including the ability for the maintainer of this module to respond quickly to Twitter API changes.
See Net::Twitter::Lite if you need an alternative without Moose and its dependencies.
Net::Twitter::Lite's API method definitions and documentation are generated from Net::Twitter. It is a related module, but does not depend on Net::Twitter or Moose for installation.
Net::Twitter decodes the data structures returned by the Twitter API into native perl data structures (HASH references and ARRAY references). The full layout of those data structures are not documented, here. They change often, usually with the addition of new elements, and documenting all of those changes would be a significant challenge.
Instead, rely on the online Twitter API documentation and inspection of the returned data.
The Twitter API online documentation is located at http://apiwiki.twitter.com/Twitter-API-Documentation.
To inspect the data, use Data::Dumper or similar module of your choice. Here's a simple example using Data::Dumper:
use Data::Dumper; my $r = $nt->search($search_term); print Dumper $r;
For more information on perl data structures, see perlreftut, perldsc, and perllol.
This constructs a Net::Twitter object. It takes several named parameters, all of them optional:
Net::Twitter
An ARRAY ref of traits used to control which APIs the constructed Net::Twitter object will support and how it handles errors. Possible values are:
Provides support for the Twitter REST API methods.
Provides support for the Twitter Search API methods.
Provides support for the TwitterVision API. See http://twittervision.com/api.html.
Net::Twitter normally throws exceptions on error. When this trait is included, Net::Twitter returns undef when a method fails and makes the error available through method get_error. This is the way all errors were handled in Net::Twitter versions prior to version 3.00.
get_error
The OAuth trait provides OAuth authentication rather than the default Basic Authentication for Twitter API method calls. See the "Authentication" section and Net::Twitter::Role::OAuth for full documentation.
OAuth
When this optional trait is included, Net::Twitter inflates HASH refs returned by Twitter into objects with read accessors for each element. In addition, it inflates dates to DateTime objects and URLs to URI objects. Objects that include a created_at attribute also have a relative_created_at method.
created_at
relative_created_at
For example, with InflateObjects applied, the <friends_timeline> method returns an array of status objects:
InflateObjects
$r = $nt->friends_timeline; for my $status ( @$r ) { $r->user->screen_name; # same as $r->{user}{screen_name} # $created_at is a DateTime; $age is a DateTime::Duration my $age = DateTime->now - $r->created_at; # print an age in a similar style to the Twitter web site, e.g.: # less than a minute ago # about a minute ago # 6 minutes ago # 1 day ago # etc. print $r->relative_created_at;
The RateLimit trait adds utility methods that return information about the current rate limit status. See Net::Twitter::Role::RateLimit for details.
RateLimit
This trait provides backwards compatibility to Net::Twitter versions prior to 3.00. It implies the traits API::REST, API::Search, API::TwitterVision, and API::WrapError. It also provides additional functionality to ensure consistent behavior for applications written for use with legacy versions of Net::Twitter.
API::REST
API::Search
API::TwitterVision
API::WrapError
In the current version, this trait is automatically included if the traits option is not specified. This ensures backwards compatibility for existing applications using Net::Twitter versions prior to 3.00. See section "LEGACY COMPATIBILITY" for more details.
traits
Some examples of using the traits parameter in new:
new
# provide support for *only* the REST API; throw exceptions on error $nt = Net::Twitter->new(traits => ['API::REST']); # provide support for both the REST and Search APIs; wrap errors $nt = Net::Twitter->new(traits => [qw/API::REST API::Search WrapError/]); # ensure full legacy support $nt = Net::Twitter->new(traits => ['Legacy']); # currently, these 2 calls to new are equivalent: $nt = Net::Twitter->new(); $nt = Net::Twitter->new(traits => ['Legacy']);
A boolean. If set to 0, new constructs a Net::Twitter object implementing the REST API and throws exceptions on API method errors.
Net::Twitter->new(legacy => 0);
is a shortcut for:
Net::Twitter->new(traits => ['API::REST']);
If set to 1, new constructs a Net::Twitter object with the Legacy trait.
Legacy
Net::Twitter->new(legacy => 1);
Net::Twitter->new(traits => ['Legacy']);
This is the screen name or email used to authenticate with Twitter.
This is the password used to authenticate with Twitter.
The value for the X-Twitter-Client-Name HTTP header. It defaults to "Perl Net::Twitter".
X-Twitter-Client-Name
The value for the X-Twitter-Client-Version HTTP header. It defaults to current version of the Net::Twitter module.
X-Twitter-Client-Version
The value for the X-Twitter-Client-URL HTTP header. It defaults to the search.cpan.org page for the Net::Twitter distribution.
X-Twitter-Client-URL
The LWP::UserAgent compatible class used internally by Net::Twitter. It defaults to "LWP::UserAgent". For POE based applications, consider using "LWP::UserAgent::POE".
LWP::UserAgent
An HASH ref of arguments to pass to constructor of the class specified with useragent_class, above. It defaults to {} (an empty HASH ref).
useragent_class
The value for User-Agent HTTP header. It defaults to "Net::Twitter/$VERSION (Perl)", where $VERSION is the current version of Net::Twitter.
User-Agent
$VERSION
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 when displayed via the Twitter web interface.
source
update
Twitter is no longer registering source parameters. New applications should implement OAuth and register via http://twitter.com/oauth_clients.
Only use the source parameter if you have an existing, registered source parameter from Twitter.
The URL for the Twitter API. This defaults to "http://api.twitter.com/1". This option is available when the API::REST trait is included.
DEPRECATED - Setting the apiurl is sufficient.
apiurl
A string containing the Twitter API realm used for Basic Authentication. It defaults to "Twitter API". This option is available when the API::REST trait is included.
If set to 1, Net::Twitter overrides the defaults for apiurl, apihost, and apirealm to "http://identi.ca/api", "identi.ca:80", and "Laconica API" respectively. It defaults to 0. This option is available when the API::REST trait is included.
apihost
apirealm
A string containing the OAuth consumer key provided by Twitter when an application is registered. This option is available when the OAuth trait is included.
A string containing the OAuth consumer secret. This option is available when the OAuth trait is included.
If set to 1, an SSL connection will be used for all API calls. Defaults to 0.
(Optional) Sets the machine key to look up in .netrc to obtain credentials. If set to 1, Net::Twitter will use the value of the netrc_machine option (below).
.netrc
netrc_machine
# 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->new(netrc => 1); $nt = Net::Twitter->new(netrc => 'semifor.twitter.com');
(Optional) Sets the machine entry to look up in .netrc when <netrc = 1>> is used. Defaults to api.twitter.com.
machine
<netrc =
api.twitter.com
Twitter encodes HTML entities in the text field of statuses. Set this option to 1 to have them automatically decoded. Default 0.
text
Set the credentials for Basic Authentication. This is helpful for managing multiple accounts.
Provides access to the constructed user agent object used internally by Net::Twitter. Use it with caution.
Twitter currently provides two authentication strategies: Basic Authentication and OAuth. OAuth is officially in beta, however, Twitter has expressed a desire to deprecate Basic Authentication in the future, so consider using OAuth in your applications.
To set up Basic Authentication in Net::Twitter, provide the username and password options to "new" or call the "credentials" method.
username
password
To set up OAuth, include the OAuth trait and include the consumer_key and consumer_secret options to "new". See Net::Twitter::Role::OAuth for more information on using OAuth, including examples.
consumer_key
consumer_secret
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).
authenticate
Authorization
authenticated => 1
authentication => 0
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.
Most Twitter API methods take parameters. All Net::Twitter API methods will accept a HASH ref of named parameters as specified in the Twitter API documentation. For convenience, many Net::Twitter 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:
status
$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:
in_reply_to_status_id
$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 });
Some methods return partial results a page at a time. Originally, methods that returned partial results used a page parameter. A more recent addition to the Twitter API for retrieving multiple pages uses the cursor parameter. Usually, a method uses either the page parameter or the cursor parameter, but not both. There have been exceptions to this rule when Twitter deprecates the use of page for a method in favor of cursor. In that case, both methods may work during a transition period. So, if a method supports both, you should always use the cursor parameter.
page
cursor
For methods that support paging, the first page is returned by passing page => 1, the second page by passing page => 2, etc. If no page parameter is passed, the first page is returned.
page => 1
page => 2
Here's an example that demonstrates how to obtain all favorites in a loop:
my @favs; for ( my $page = 1; ; ++$page ) { my $r = $nt->favorites({ page => $page }); last unless @$r; push @favs, @$r; }
Cursoring employs a different strategy. To obtain the first page of results, pass cursor => -1. Twitter returns a reference to a hash that includes entries next_cursor, previous_cursor, and an entry with a reference to an array containing a page of the requested items. The key for the array reference will be named users, ids, or something similar depending upon the type of returned items. For example, when cursor parameter is used with the followers_ids method, the returned in hash entry ids.
cursor => -1
next_cursor
previous_cursor
users
ids
followers_ids
The next_cursor value can be used in a subsequent call to obtain the next page of results. When you have obtained the last page of results, next_cursor will be 0. Likewise, you can use the value for previous_cursor to obtain the previous page of results. When you have obtained the first page, previous_cursor will be 0.
Here's an example that demonstrates how to obtain all follower IDs in a loop using the cursor parameter:
my @ids; for ( my $cursor = -1, my $r; $cursor; $cursor = $r->{next_cursor} ) { $r = $nt->followers_ids({ cursor => $cursor }); push @ids, @{ $r->{ids} }; }
In addition to the arguments described in the Twitter API Documentation for each API method, Net::Twitter supports additional synthetic arguments.
When set to 1, Net::Twitter will provide an Authorization header for the API call; when set to 0, it will suppress the Authentication header. This argument overrides the defined authentication behavior for the API method. It is probably only useful for the rate_limit_satus method which returns different values for authenticated and unauthenticated calls. See "AUTHENTICATION" for more details.
rate_limit_satus
API methods that accept the since_id argument will also accept the synthetic since argument, instead. since may be a Date::Time object, an epoch time (the number of seconds since the system epoch), or a string in the same format returned by Twitter for the created_at attribute. Only statuses with a created_at time greater than since will be returned by the API call.
since_id
since
Date::Time
These methods are provided when trait API::REST is included in the traits option to new.
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.
id
screen_name
user_id
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.
Returns if the authenticating user is blocking a target user. Will return the blocked user's object if a block exists, and error with HTTP 404 response code otherwise.
Returns: BasicUser
Returns an array of user objects that the authenticating user is blocking.
Returns: ArrayRef[BasicUser]
Returns an array of numeric user ids the authenticating user is blocking.
Returns: ArrayRef[Int]

Favorites the status specified in the ID parameter as the authenticating user. Returns the favorite status when successful.
Returns: Status
Befriends the user specified in the ID parameter as the authenticating user. Returns the befriended user when successful. Returns a string describing the failure condition when unsuccessful.
Creates a saved search for the authenticated user.
Returns: SavedSearch
Un-blocks the user specified in the ID parameter as the authenticating user. Returns the un-blocked user when successful.

Ends the session of the authenticating user, returning a null cookie. Use this method to sign users out of client-facing applications like widgets.
Returns: Error
Returns the 20 most recent favorite statuses for the authenticating user or user specified by the ID parameter.
Returns: ArrayRef[Status]
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]
Returns a reference to an array of numeric IDs for every user following the specified user.
Use the optional cursor parameter to retrieve IDs in pages of 5000. 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]
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.
Returns: Hashref|ArrayRef[User]
Returns a reference to an array of numeric IDs for every user followed the specified user.
Use the optional cursor parameter to retrieve IDs in pages of 5000. 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 friends. 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 the 20 most recent statuses posted by the authenticating user and that user's friends. This is the equivalent of /home on the Web.
Tests for the existence of friendship between two users. Will return true if user_a follows user_b, otherwise will return false.
Returns: Bool
Returns the 20 most recent statuses, including retweets, posted by the authenticating user and that user's friends. This is the equivalent of /timeline/home on the Web.
Returns the 20 most recent mentions (statuses containing @username) for the authenticating user.
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.
user
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.
public_timeline
->public_timeline({ authenticate => 0 })
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.)
->rate_limit_status({ authenticate => 0 })
Returns: RateLimitStatus
The user specified in the id is blocked by the authenticated user and reported as a spammer.
Returns: User
Retweets a tweet. Requires the id parameter of the tweet you are retweeting. Returns the original tweet with retweet details embedded.
Returns the 20 most recent retweets posted by the authenticating user.
Returns the 20 most recent retweets posted by the authenticating user's friends.
Returns up to 100 of the first retweets of a given tweet.
Returns: Arrayref[Status]
Returns the 20 most recent tweets of the authenticated user that have been retweeted by others.
Returns the authenticated user's saved search queries.
Returns: ArrayRef[SavedSearch]
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 detailed information about the relationship between two users.
Returns: Relationship
Retrieve the data for a saved search, by ID, owned by the authenticating user.
Returns a single status, specified by the id parameter. The status's author will be returned inline.
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
Returns the string "ok" status code.
Returns: Str
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 http://developer.yahoo.com/geo/geoplanet/) 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.
lat
long
Use the WOEID returned in the location object to query trends for a specific location.
Returns: ArrayRef[Location]
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]
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.
The optional lat and long parameters add location data to the status for a geo enabled account. They expect values in the ranges -90.0 to +90.0 and -180.0 to +180.0 respectively. They are ignored unless the user's geo_enabled field is true.
geo_enabled
Sets which device Twitter delivers updates to for the authenticating user. Sending none as the device parameter will disable IM or SMS updates.
Sets values that users are able to set under the "Account" tab of their settings page. Only the parameters specified will be updated; to only update the "name" attribute, for example, only include that parameter in your request.
Updates the authenticating user's profile background image. The image parameter must be an arrayref with the same interpretation as the image parameter in the update_profile_image method. See that method's documentation for details.
image
update_profile_image
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.
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().
$file
$filename
$mime_type
$raw_image_data can be provided, rather than opening a file, by passing undef as the first array value.
$raw_image_data
undef
Returns the 20 most recent statuses posted from the authenticating user. It's also possible to request another user's timeline via the id parameter. This is the equivalent of the Web /archive page for your own user, or the profile page for a third party.
Run a search for users similar to Find People button on Twitter.com; the same results returned by people search on Twitter.com will be returned by using this API (about being listed in the People Search). It is only possible to retrieve the first 1000 matches from this API.
Returns: ArrayRef[Users]
Returns an HTTP 200 OK response code and a representation of the requesting user if authentication was successful; returns a 401 status code and an error message if not. Use this method to test if supplied user credentials are valid.
These methods are provided when trait API::Search is included in the traits option to new.
Returns a HASH reference with some meta-data about the query including the next_page, refresh_url, and max_id. The statuses are returned in results. To iterate over the results, use something similar to:
next_page
refresh_url
max_id
results
my $r = $nt->search($searh_term); for my $status ( @{$r->{results}} ) { print "$status->{text}\n"; }
Returns: HashRef
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]
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 the top 20 trending topics for each hour in a given day.
Returns the top 30 trending topics for each day in a given week.
These methods are provided when trait API::TwitterVision is included in the traits option to new.
Get the current location and status of a user.
Updates the location for the authenticated user.
For Lists API support, add trait API::Lists to the traits option in new.
API::Lists
For full documentation of the Lists API, see Net::Twitter::Role::API::Lists.
use Net::Twitter; my $nt = Net::Twitter->new(traits => ['API::Lists'], ...); $list = $nt->create_list($owner, { name => $name, description => $desc }); $list = $nt->update_list($owner, $list_id, { description => $desc }); $lists = $nt->get_lists($owner); $lists = $nt->list_lists($owner); $list = $nt->get_list($owner, $list_id); $list = $nt->delete_list($owner, $list_id); $statuses = $nt->list_statuses($owner, $list_id); $lists = $nt->list_memberships($owner); $lists = $nt->list_subscriptions($owner); $users = $nt->list_members($owner, $list_id); $user_or_undef = $nt->list_members($owner, $list_id, { id => $user_id }); $user = $nt->add_list_member($owner, $list_id, $user_id); $user = $nt->delete_list_member($owner, $list_id, $user_id); $user = $nt->remove_list_member($owner, $list_id, $user_id); $user_or_undef = $nt->is_list_member($owner, $list_id, $user_id); $users = $nt->list_subscribers($owner, $list_id); $list = $nt->subscribe_list($owner, $list_id); $list = $nt->unsubscribe_list($owner, $list_id); $user_or_undef = $nt->is_subscribed_list($owner, $list_id, $user_id); $user_or_undef = $nt->is_list_subscriber($owner, $list_id, $user_id);
This version of Net::Twitter automatically includes the Legacy trait if no traits option is provided to new. Therefore, these 2 calls are currently equivalent:
$nt = Net::Twitter->new(username => $user, password => $passwd); $nt = Net::Twitter->new( username => $user, password => $passwd, traits => ['Legacy'], );
Thus, existing applications written for a prior version of Net::Twitter should continue to run, without modification, with this version.
In a future release, the default traits may change. Prior to that change, however, a nearer future version will add a warning if no traits option is provided to new. To avoid this warning, add an appropriate traits option to your existing application code.
There are currently two strategies for handling errors: throwing exceptions and wrapping errors. Exception handling is the newer, recommended strategy.
When trait WrapError is specified (or Legacy, which includes trait WrapError), Net::Twitter returns undef on error. To retrieve information about the error, use methods http_code, http_message, and get_error. These methods are described in the Net::Twitter::Role::WrapError.
WrapError
http_code
http_message
if ( my $followers = $nt->followers ) { for my $follower ( @$followers ) { #... } } else { warn "HTTP message: ", $nt->http_message, "\n"; }
Since an error is stored in the object instance, this error handling strategy is problematic when using a user agent like LWP::UserAgent::POE that provides concurrent requests. The error for one request can be overwritten by a concurrent request before you have an opportunity to access it.
LWP::UserAgent::POE
When Net::Twitter encounters a Twitter API error or a network error, it throws a Net::Twitter::Error object. You can catch and process these exceptions by using eval blocks and testing $@:
Net::Twitter::Error
eval
eval { my $statuses = $nt->friends_timeline(); # this might die! for my $status ( @$statuses ) { #... } }; if ( $@ ) { # friends_timeline encountered an error if ( blessed $@ && $@->isa('Net::Twitter::Error') ) { #... use the thrown error obj warn $@->error; } else { # something bad happened! die $@; } }
Net::Twitter::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"; }
->followers({ screen_name => $friend })
$friends
First, check carefully to make sure you've spelled "screen_name" correctly. Twitter sometimes discards parameters it doesn't recognize. In this case, the result is a list of your own followers---the same thing that would happen if you called followers without the screen_name parameter.
followers
geocode
The geocode parameter value includes a latitude, longitude, and radius separated with commas.
$r = $nt->search({ geocode => "45.511795,-122.675629,25mi" });
