An interface for using the Flickr API.

"Flickr::API" is a subclass of LWP::UserAgent, so all of the various proxy, request limits, caching, etc are available. "Flickr::API" can instantiate using either the Flickr Authentication (deprecated) or the OAuth Authentication. OAuth is handled using Net::OAuth.

"new({ opt => 'value', ... })"
Returns as new Flickr::API object. The options are as follows:
either "api_key" for the Flickr auth or "consumer_key" for OAuth
Your API key (one or the other form is required)
either "api_secret" for the Flickr auth or "consumer_secret" for OAuth
Your API key's secret (the one matching the api_key/consumer_key is required)
"rest_uri" & "auth_uri"
Override the URIs used for contacting the API.
"lwpobj"
Base the "Flickr::API" on this object, instead of creating a new instance of LWP::UserAgent. This is useful for using the features of e.g. LWP::UserAgent::Cached.
"unicode"
This flag controls whether Flickr::API expects you to pass UTF-8 bytes (unicode=0, the default) or actual unicode strings (unicode=1) in the request.
"nonce", "timestamp", "request_method", "signature_method", "request_url"
These values are used by Net::OAuth to assemble and sign OAuth consumer request Flickr API calls. The defaults are usually fine.
"callback"
The callback is used in oauth authentication. When Flickr authorizes you, it returns the access token and access token secret in a callback URL. This defaults to https://127.0.0.1/
"token" and "token_secret"
These values are used by Net::OAuth to assemble and sign OAuth protected resource request Flickr API calls.
"execute_method($method, $args)"
Constructs a Flickr::API::Request object and executes it, returning a Flickr::API::Response object.
"execute_request($request)"
Executes a Flickr::API::Request object, returning a Flickr::API::Response object. Calls are signed if a secret was specified when creating the Flickr::API object.
"request_auth_url($perms,$frob)"
Returns a URI object representing the URL that an application must redirect a user to for approving an authentication token.

$perms must be read, write, or delete.

For web-based applications $frob is an optional parameter.

Returns undef if a secret was not specified when creating the "Flickr::API" object.

"export_config([$type,$params])"
Returns a hash of all or part of the persistent parts of the Flickr::API object with additional behaviors for Flickr::API objects using OAuth.
oauth message type: one of "Consumer", "Protected Resource", "Request Token", "Authorize User" or "Access Token"
This is one of the the message type that Net::OAuth handles. Message type is optional.
oauth parameter set: "message" or "API" or undef.
Net::OAuth will return message params, api params or all params depending on what is requested. All params is the default.

If the Flickr::API object identifies as Flickr original authentication, return a hashref

  $VAR1 = {
            'frob' => '12332112332112300-feedabcde123456c-1234567',
            'api_key' => 'cafefeedbeef13579246801234567890',
            'api_secret' => 'beef321432154321',
            'token' => '97531086421234567-cafe123456789abc'
          };

or the subset thereof depending on what has been used by the API. If the older form of key/secret was used, the constructor will change these to the api_key/api_secret forms.

If the API object identifies as OAuth authentication, and "message type" is specified, then export_config will return a hash of the OAuth parameters for the specified Net::OAuth message type. Further, if parameter is specified, then export_config returns either either the set of message parameters or api parameters for the message type. If parameter is not specified then both parameter type are returned. For example:

  my %config = $api->export_config('protected resource');

or

  my %config = $api->export_config('protected resource','message');

When export_config is called without arguments, then it returns the OAuth portion of the Flickr::API object. If present the Net::OAuth Request Token and Access Token objects are also included.

  VAR1 = {
            'access_token' => bless( {
                                       'extra_params' => {
                                                           'fullname' => 'Louis',
                                                           'user_nsid' => '12345678@N00',
                                                           'username' => 'meanameicallmyself'
                                                         },
                                       'from_hash' => 1,
                                       'token' => '12345678901234567-cafe123098765432',
                                       'token_secret' => 'eebeef000fedbca1'
                                     }, 'Net::OAuth::AccessTokenResponse' ),
            'callback' => 'https://127.0.0.1',
            'consumer_key' => 'cafefeedbeef13579246801234567890',
            'consumer_secret' => 'fedcba9876543210',
            'nonce' => '917fa882fa7babd5a1b7702e7d19502a',
            'request_method' => 'GET',
            'request_url' => 'https://api.flickr.com/services/rest/',
            'signature_method' => 'HMAC-SHA1',
            'timestamp' => 1436129308,
            'token' => '12345678901234567-cafe123098765432',
            'token_secret' => 'eebeef000fedbca1',
            'version' => '1.0'
          };

  my %config = $api->export_config();

This method can be used to extract and save the API parameters for future use.

"export_storable_config(filename)"
This method wraps export_config with a file open and storable store_fd to add some persistence to a Flickr::API object.
"import_storable_config(filename)"
This method retrieves a storable config of a Flickr::API object and revivifies the object.
"get_oauth_request_type()"
Returns the oauth request type in the Flickr::API object. Some Flickr methods will require a "protected resource" request type and others a simple "consumer" request type.
"oauth_request_token(\%args)"
Assembles, signs, and makes the OAuth Request Token call, and if sucessful stores the Net::OAuth Request Token in the Flickr::API object.

The required parameters are:

"consumer_key"
Your API Key
"consumer_secret"
Your API Key's secret
"request_method"
The URI Method: GET or POST
"request_url"
Defaults to: <https://api.flickr.com/services/oauth/request_token>
"flickr_access_token"
The required parameters are:
"key"
"oauth_access_token(\%args)"
Assembles, signs, and makes the OAuth Access Token call, and if sucessful stores the Net::OAuth Access Token in the Flickr::API object.

The required parameters are:

"consumer_key"
Your API Key
"consumer_secret"
Your API Key's secret
"request_method"
The URI Method: GET or POST
"request_url"
Defaults to: <https://api.flickr.com/services/oauth/access_token>
"token_secret"
The request token secret from the Net::OAuth Request Token object returned from the oauth_request_token call.
"oauth_authorize_uri(\%args)"
Returns a URI object representing the URL that an application must redirect a user to for approving a request token.
"perms"
Permission the application is requesting, one of read, write, or delete, defaults to read.
"is_oauth"
Returns 1 if the Flickr::API object is OAuth flavored, 0 otherwise.
