Service module example: Echo service
Last updated on
30 April 2025
This service can be useful as an example, and as a test to make sure the services are functioning. This module simply replies with the message it is sent.
/**
* Implementation of hook_help().
*/
function echo_service_help($section) {
switch ($section) {
case 'admin/help#services_node':
return t('<p>Provides echo methods to services applications. Requires services.module.</p>');
case 'admin/modules#description':
return t('Provides echo methods to services applications. Requires services.module.');
}
}
/**
* Implementation of hook_service()
*/
function echo_service_service() {
return array(
// echo.echo
array(
'#method' => 'echo.echo',
'#callback' => 'echo_service_echo',
//'#auth' => false,
'#return' => 'struct',
'#args' => array(
array(
'#name' => 'message',
'#type' => 'string',
'#description' => t('The message to return.'),
)),
'#help' => t('Returns an object containing a sessid and user.'))
);
}
function echo_service_echo($message) {
$return = new stdClass();
$return->sessid = session_id();
$return->message = $message;
return $return;
}
To install, in your modules directory make a directory named echo_service and install the above file as echo_service.module. Then put the following in that directory as echo_service.info. Then go to Administer > Site building > Modules and enable the Echo Service that shows up.
