# Catching Gdata Exceptions The Zend_Gdata_App_Exception class is a base class for exceptions thrown by Zend_Gdata. You can catch any exception thrown by Zend_Gdata by catching Zend_Gdata_App_Exception. try { $client = Zend_Gdata_ClientLogin::getHttpClient($username, $password); } catch(Zend_Gdata_App_Exception $ex) { // Report the exception to the user die($ex->getMessage()); } The following exception subclasses are used by Zend_Gdata: Zend_Gdata_App_AuthException indicates that the user's account credentials were not valid. Zend_Gdata_App_BadMethodCallException indicates that a method was called for a service that does not support the method. For example, the CodeSearch service does not support post(). Zend_Gdata_App_HttpException indicates that an HTTP request was not successful. Provides the ability to get the full Zend_Http_Response object to determine the exact cause of the failure in cases where $e->getMessage() does not provide enough details. Zend_Gdata_App_InvalidArgumentException is thrown when the application provides a value that is not valid in a given context. For example, specifying a Calendar visibility value of "banana", or fetching a Blogger feed without specifying any blog name. Zend_Gdata_App_CaptchaRequiredException is thrown when a ClientLogin attempt receives a CAPTCHA challenge from the authentication service. This exception contains a token ID and a URL to a CAPTCHA challenge image. The image is a visual puzzle that should be displayed to the user. After collecting the user's response to the challenge image, the response can be included with the next ClientLogin attempt.The user can alternatively be directed to this website: `https://www.google.com/accounts/DisplayUnlockCaptcha` Further information can be found in the ClientLogin documentation. You can use these exception subclasses to handle specific exceptions differently. See the API documentation for information on which exception subclasses are thrown by which methods in Zend_Gdata. try { $client = Zend_Gdata_ClientLogin::getHttpClient($username, $password, $service); } catch(Zend_Gdata_App_AuthException $authEx) { // The user's credentials were incorrect. // It would be appropriate to give the user a second try. ... } catch(Zend_Gdata_App_HttpException $httpEx) { // Google Data servers cannot be contacted. die($httpEx->getMessage);}
