net-twitter-lite's Introduction
NAME
Net::Twitter::Lite - A perl interface to the Twitter API
VERSION
This document describes Net::Twitter::Lite version 0.09001
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/0.09001 (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
<http://apiwiki.twitter.com/FAQ#HowdoIget%E2%80%9CfromMyApp%E2%8
0%9DappendedtoupdatessentfrommyAPIapplication>.
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);
$nt = Net::Twitter::Lite->new(netrc => 'semifor.twitter.com');
netrc_machine
(Optional) Sets the "machine" entry to look up in ".netrc" when
"<netrc =" 1>> is used. Defaults to "api.twitter.com".
BASIC AUTHENTICATION METHODS
credentials($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.

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

element for every protected user for whom the authenticating user
has a pending follow request.
Returns: HashRef
geo_id
geo_id(id)
Parameters: id
Required: id
Returns details of a place returned from the "reverse_geocode"
method.
Returns: HashRef
home_timeline
Parameters: since_id, max_id, count, page, skip_user
Required: *none*
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: ArrayRef[Status]
mentions
alias: replies
Parameters: since_id, max_id, count, page
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
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
public_timeline
public_timeline(skip_user)
Parameters: skip_user
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
report_spam
report_spam(id)
Parameters: id, user_id, screen_name
Required: id
The user specified in the id is blocked by the authenticated user
and reported as a spammer.
Returns: User
retweet
retweet(id)

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

author will be returned inline.
Returns: Status
show_user
show_user(id)
Parameters: id
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
test
Parameters: *none*
Required: *none*
Returns the string "ok" status code.
Returns: Str
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
<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.
Use the WOEID returned in the location object to query trends for a
specific location.
Returns: ArrayRef[Location]
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]
update
update(status)
Parameters: status, lat, long, place_id, display_coordinates,
in_reply_to_status_id
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.
Returns: Status
update_delivery_device
update_delivery_device(device)
Parameters: device
Required: device
Sets which device Twitter delivers updates to for the authenticating
user. Sending none as the device parameter will disable IM or SMS
updates.
Returns: BasicUser
update_profile
Parameters: name, email, url, location, description
Required: *none*
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.
Returns: ExtendedUser
update_profile_background_image
update_profile_background_image(image)
Parameters: image
Required: image
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.
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_timeline
Parameters: id, user_id, screen_name, since_id, max_id, count, page,
skip_user
Required: *none*
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.
Returns: ArrayRef[Status]
users_search
users_search(q)
alias: find_people
alias: search_users
Parameters: q, per_page, page
Required: q
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]
verify_credentials
Parameters: *none*
Required: *none*
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.

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 = <STDIN>; # 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($access_token, $access_token_secret, $user_id, $screen_name) =
$nt->request_access_token;
# 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 });
}
