Adding custom web service functions was created by saeid

Hi,

I downloaded and installed this plugin:
www.joomdle.com/download/category/35-dev...le-web-services-demo

Then I added the testjoomdlewsdemo function to Joomdle external services.

But when I call the function in Joomla by this code:

Code:

require_once 'administrator/components/com_joomdle/helpers/content.php';

$return = JoomdleHelperContent::call_method ('testjoomdlewsdemo', "TEST STRING");
print_r($return);

It gives this error:
ERROR: Joomdle external signature not found: testjoomdlewsdemo

Please help.

Hi.

I'll need to update this example plugin to include support for REST, as it is outdated now.

Sorry for the delay. It was not the plugin that needs updating, I need to modify Joomdle core to allow for direct REST web service calls. I will do so for next release.

If you want, you can add the code yourself.
File: administrator/components/com_joomdle/helpers/content.php

Code:

    static function call_method_rest_named_params ($method, $params)
    {
        $cm = JoomdleHelperContent::_get_cm ();

        if ($cm == 'fgc')
            $response = JoomdleHelperContent::call_method_rest_fgc_named_params ($method, $params);
        else
            $response = JoomdleHelperContent::call_method_rest_curl_named_params ($method, $params);

        return $response;
    }

    static function call_method_rest_curl_named_params ($method, $params)
    {
        $moodle_rest_server_url = JoomdleHelperContent::_get_rest_url ();

        $url = $moodle_rest_server_url . '&wsfunction=joomdle_' . $method;

        $request = JoomdleHelperContent::format_postdata_for_curlcall($params);

        $headers = array();
        array_push($headers,"Content-Type: application/x-www-form-urlencoded");
        array_push($headers,"Content-Length: ".strlen($request));
        array_push($headers,"\r\n");

        $ch = curl_init();
        curl_setopt( $ch, CURLOPT_URL, $url); # URL to post to
        curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 ); # return into a variable
        curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers ); # custom headers, see above
        curl_setopt( $ch, CURLOPT_POSTFIELDS, $request );
        curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, 'POST' ); # This POST is special, and uses its specified Content-type
        $response = curl_exec( $ch ); # run!
        curl_close($ch);

        $response = trim ($response);
        $response = json_decode ($response, true);

        return $response;
    }

    static function call_method_rest_fgc_named_params ($method, $params)
    {
        $moodle_rest_server_url = JoomdleHelperContent::_get_rest_url ();

        $url = $moodle_rest_server_url . '&wsfunction=joomdle_' . $method;

        $request = JoomdleHelperContent::format_postdata_for_curlcall($params);

        $context = stream_context_create(array('http' => array(
                    'method' => "POST",
                    'header' => "Content-Type: application/x-www-form-urlencoded",
                    'content' => $request
                        )));
        $file = @file_get_contents($url , false, $context);
        $file = trim ($file);
        $response = json_decode ($file, true);

        return $response;
    }

Then, you can call the method like this:

Code:

 $a = JoomdleHelperContent::call_method_rest_named_params ('testjoomdlewsdemo', array ('teststring' => "TEST STRING"));
        echo "<pre>"; print_R ($a);
