Gentics CMS JavaScript API

1 authentication-required

Read and write operations to Gentics CMS objects that reside on the server require an authenticated session. An authentication-required message is published when a valid session is not available while attempting to carry out such operations that require an authenticated request to the Gentics CMS back-end.

The handler will receive two callback functions: proceed and cancel, which allow the control of the program to be branched towards continuing the interrupted process once authentication has been established, or canceling the operation if authentication could to be accomplished (eg: when a login attempt fails).

1.1 Example


GCN.sub('authentication-required', function (proceed, cancel) {
	var user = prompt('Username:');
	var pass = prompt('Password:');

	GCN.login(user, pass, function(success, data) {
		if (success) {
			proceed();
		} else {
			cancel();
		}
	});
});

The handler registered via authentication-required would typically invoke the login() method with appropriate credentials to attempt to log into the the Gentics CMS back-end.

The login() function is used to log into Gentics CMS. The function has three parameters: username, password, a success callback, and an optional error callback.

2.1 success

The success callback function will be invoked once the login request has been made. It receives a boolean as its first argument, to indicate whether or not the login attempt succeeded. The second argument is an object that contains the necessary data depending on the success of the login attempt. If the login attempt did succeed, this data object will contain a user property, otherwise it will contain an error property which holds a Gentics CMS error object.

2.2 error

The optional error callback function can be used to handle ajax errors when the login request could not be made. It receives a Gentics CMS error object as its only argument. If this handler returns false, the error will not be propagated to the global onError handler.

2.3 Example


GCN.login('John', 'Doe', function(success, data ) {
	if (success) {
		alert('Hello, ' + data.user.firstName + '!');
	} else {
		alert('Login failed: ' + data.error.toString());
	}
}, function(error) {
	alert('Log in could not be accomplished. ' + error.toString());
});

3 logout()

Logs the user out of the current Gentics CMS session and destroys the session data that is stored by the Gentics CMS JavaScript API. The logout function has two parameters: the first is a callback that will be invoked once the logout request is completed. This handler takes two arguments: success, and error. The success argument is a boolean that indicates whether or not the logout request succeeded. If logout fails, an extra error object is returned. This object is the Gentics CMS error object.

The second argument that the logout function takes, is an optional error handler. This callback is invoked when an ajax transport error occurs that prevents request from being accomplished.

3.1 Example


GCN.logout(function(success, error) {
	if (success) {
		// error is `null'
		alert('Logout was successful.');
	} else {
		alert('Logout failed. ' + error.toString());
	}
});

4 setSid()

Allows the session id to be set manually. This function takes one argument: the sid to be set.

5 usingSSO

A flag indicating whether credential login, or single-signon is to be used for authentication.
