Net::Google::AuthSub - interact with sites that implement Google style AuthSub SYNOPSIS
my $auth = Net::Google::AuthSub->new; my $response = $auth->login($user, $pass); if ($response->is_success) { print "Hurrah! Logged in "; } else { die "Login failed: ".$response->error." "; } my %params = $auth->auth_params; $params{Content_Type} = 'application/atom+xml; charset=UTF-8'; $params{Content} = $xml; $params{'X-HTTP-Method-Override'} = 'DELETE'; my $request = POST $url, %params; my $r = $user_agent->request( $request ); ABOUT AUTHSUB
AuthSub is Google's method of authentication for their web services. It is also used by other web sites. You can read more about it here. http://code.google.com/apis/accounts/Authentication.html A Google Group for AuthSub is here. http://groups.google.com/group/Google-Accounts-API DEALING WITH CAPTCHAS
If a login response fails then it may set the error code to 'CaptchRequired' and the response object will allow you to retrieve the "captchatoken" and "captchaurl" fields. The "captchaurl" will be the url to a captcha image or you can show the user the web page https://www.google.com/accounts/DisplayUnlockCaptcha Then retry the login attempt passing in the parameters "logintoken" (which is the value of "captchatoken") and "logincaptcha" which is the user's answer to the CAPTCHA. my $auth = Net::Google::AuthSub->new; my $res = $auth->login($user, $pass); if (!$res->is_success && $res->error eq 'CaptchaRequired') { my $answer = display_captcha($res->captchaurl); $auth->login($user, $pass, logintoken => $res->captchatoken, logincaptcha => $answer); } You can read more here http://code.google.com/apis/accounts/AuthForInstalledApps.html#Using METHODS
new [param[s]] Return a new authorisation object. The options are url The base url of the web service to authenticate against. Defaults to "https://google.com/account" service Name of the Google service for which authorization is requested such as 'cl' for Calendar. Defaults to 'xapi' for calendar. source Short string identifying your application, for logging purposes. Defaults to 'Net::Google::AuthSub-<VERSION>' accountType Type of account to be authenticated. Defaults to 'HOSTED_OR_GOOGLE'. See http://code.google.com/apis/accounts/AuthForInstalledApps.html#ClientLogin for more details. login <username> <password> [opt[s]] Login to google using your username and password. Can optionally take a hash of options which will override the default login params. Returns a "Net::Google::AuthSub::Response" object. authorised Whether or not we're authorised. authorized An alias for authorized. auth <username> <token> Use the AuthSub method for access. See http://code.google.com/apis/accounts/AuthForWebApps.html for details. auth_token [token] Get or set the current auth token auth_type [type] Get or set the current auth type Returns either $Net::Google::AuthSub::CLIENT_LOGIN or $Net::Google::AuthSub::AUTH_SUB. request_token <next> <scope> [option[s]] Return a URI object representing the URL which the user should be directed to in order to aquire a single use token. The parameters are next (required) URL the user should be redirected to after a successful login. This value should be a page on the web application site, and can include query parameters. scope (required) URL identifying the service to be accessed. The resulting token will enable access to the specified service only. Some services may limit scope further, such as read-only access. For example http://www.google.com/calendar/feed secure Boolean flag indicating whether the authentication transaction should issue a secure token(1) or a non-secure token(0). Secure tokens are available to registered applications only. session Boolean flag indicating whether the one-time-use token may be exchanged for a session token(1) or not(0). session_token Exchange the temporary token for a long-lived session token. The single-use token is acquired by visiting the url generated by calling request_token. Returns the token if success and undef if failure. revoke_token Revoke a valid session token. Session tokens have no expiration date and will remain valid unless revoked. Returns 1 if success and undef if failure. token_info Call AuthSubTokenInfo to test whether a given session token is valid. This method validates the token in the same way that a Google service would; application developers can use this method to verify that their application is getting valid tokens and handling them appropriately without involving a call to the Google service. It can also be used to get information about the token, including next URL, scope, and secure status, as specified in the original token request. Returns a "Net::Google::AuthSub::Response" object on success or undef on failure. auth_params Return any parameters needed in an HTTP request to authorise your app. AUTHOR
