◆ markAuthenticationCall()

CAS_Client::markAuthenticationCall ( $auth )

Mark the caller of authentication.

This will help client integraters determine problems with their code flow if they call a function such as getUser() before authentication has occurred.

Parameters

bool $auth True if authentication was successful, false otherwise.

Returns: null

Definition at line 761 of file Client.php.

References array.

◆ setCasAttributeParserCallback()

CAS_Client::setCasAttributeParserCallback	(		$function,
		array	$additionalArgs = `array()`
	)

Set a callback function to be run when parsing CAS attributes.

The callback function will be passed a XMLNode as its first parameter, followed by any $additionalArgs you pass.

Parameters

string	$function	callback function to call
array	$additionalArgs	optional array of arguments

Returns: void

Definition at line 664 of file Client.php.

         $this->_casAttributeParserCallbackFunction = $function;
         $this->_casAttributeParserCallbackArgs = $additionalArgs;
     }

◆ setNoClearTicketsFromUrl()

CAS_Client::setNoClearTicketsFromUrl ( )

Configure the client to not send redirect headers and call exit() on authentication success.

The normal redirect is used to remove the service ticket from the client's URL, but for running unit tests we need to continue without exiting.

Needed for testing authentication

Returns: void

Definition at line 638 of file Client.php.

◆ setPostAuthenticateCallback()

CAS_Client::setPostAuthenticateCallback	(		$function,
		array	$additionalArgs = `array()`
	)

Set a callback function to be run when a user authenticates.

The callback function will be passed a $logoutTicket as its first parameter, followed by any $additionalArgs you pass. The $logoutTicket parameter is an opaque string that can be used to map a session-id to the logout request in order to support single-signout in applications that manage their own sessions (rather than letting phpCAS start the session).

phpCAS::forceAuthentication() will always exit and forward client unless they are already authenticated. To perform an action at the moment the user logs in (such as registering an account, performing logging, etc), register a callback function here.

Parameters

string	$function	callback function to call
array	$additionalArgs	optional array of arguments

Returns: void

Definition at line 698 of file Client.php.

     {
         $this->_postAuthenticateCallbackFunction = $function;
         $this->_postAuthenticateCallbackArgs = $additionalArgs;
     }

◆ setRequestImplementation()

CAS_Client::setRequestImplementation ( $className )

Override the default implementation used to make web requests in readUrl().

This class must implement the CAS_Request_RequestInterface.

Parameters

string $className name of the RequestImplementation class

Returns: void

Definition at line 611 of file Client.php.

     {
         $obj = new $className;
         if (!($obj instanceof CAS_Request_RequestInterface)) {
             throw new CAS_InvalidArgumentException(
                 '$className must implement the CAS_Request_RequestInterface'
             );
         }
         $this->_requestImplementation = $className;
     }

◆ setSingleSignoutCallback()

CAS_Client::setSingleSignoutCallback	(		$function,
		array	$additionalArgs = `array()`
	)

Set a callback function to be run when a single-signout request is received.

The callback function will be passed a $logoutTicket as its first parameter, followed by any $additionalArgs you pass. The $logoutTicket parameter is an opaque string that can be used to map a session-id to the logout request in order to support single-signout in applications that manage their own sessions (rather than letting phpCAS start and destroy the session).

Parameters

string	$function	callback function to call
array	$additionalArgs	optional array of arguments

Returns: void

Definition at line 728 of file Client.php.

     {
         $this->_signoutCallbackFunction = $function;
         $this->_signoutCallbackArgs = $additionalArgs;
     }

◆ wasAuthenticationCalled()

CAS_Client::wasAuthenticationCalled ( )

Answer true if authentication has been checked.

Returns: bool

◆ wasAuthenticationCallSuccessful()

CAS_Client::wasAuthenticationCallSuccessful ( )

Answer the result of the authentication call.

Throws a CAS_OutOfSequenceException if wasAuthenticationCalled() is false and markAuthenticationCall() didn't happen.

Returns: bool
