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);}
