You need to have already setup a web service. You can get help from How to enable web services for ordinary users or How to enable web services for an external system . Then have a look to your security keys page. You'll find there your token and the web service documentation associated with this token.
Officially supported protocols
- REST: the Moodle REST server uses POST for parameters and XML for returned values. This server is not RESTfull.
- SOAP: the Moodle SOAP server is based on the Zend SOAP server (itself based on the PHP SOAP server). Zend publishes a Zend SOAP client. The current server implementation doesn't work with Java/.Net because we didn't generated a fully describe WSDL yet. If you are working on a Java/.Net client, follow or participate to the tracker issue MDL-20804
- XML-RPC: the Moodle XML-RPC server is based on Zend XML-RPC server. Zend also publishes a Zend XML-RPC client.
- AMF: the Moodle AMF server is based on the Zend AMF server. The test client can be found in Settings blocks > Site Administration > Development > Web service test client > AMF Test client.
PHP client examples
In all these client examples we will create two groups calling the web service function moodle_group_create_groups.
XML-RPC
The Moodle XML-RPC server extends Zend XML-RPC Server. It is recommended to have a look to the Zend XML-RPC client documentation
include 'Zend/Loader/Autoloader.php';
Zend_Loader_Autoloader::autoload('Zend_Loader');
$function = "moodle_user_get_users_by_id";
// id of the users
$params = array(array(2,4));
$serverurl = "http://{servername}/webservice/xmlrpc/server.php?wstoken=$token";
$client = new Zend_XmlRpc_Client($serverurl);
print "
";
try {
$data = $client->call($function, $params);
var_dump ($data);
} catch (exception $exception) {
var_dump ($exception);
}
print "
";
SOAP
The Moodle SOAP server extends Zend SOAP Server. It is recommended to have a look to the Zend SOAP client documentation. Except the class name Zend_Soap_Client, the entire example code would be similar to XML-RPC.
REST
Look at the web service function documentation on your security keys page to know about the returned XML structure.
//get the profile data of Moodle User
include 'Zend/Loader/Autoloader.php';
Zend_Loader_Autoloader::autoload('Zend_Loader');
$params = array(
'userids' => array(2,4), // the params to passed to the function
'wsfunction' => 'moodle_user_get_users_by_id', // the function to be called
'wstoken' => '8dc8f5ca046129706c0d85a56efcaddd' //token need to be passed in the url
);
//set web service url server
$serverurl = "http://{servername}/webservice/rest/server.php";
$client = new Zend_Http_Client($serverurl);
print "
";
try {
$client->setParameterPost($params);
$response = $client->request('POST');
var_dump ($response);
} catch (exception $exception) {
var_dump ($exception);
}
print "
";
