Web services

Hi Sonam,

I had the similar problem but I solved it.

I used the curl function in PHP page, the problem was the criteria[0] takes an array which has 'key' as a single structure and 'value' as a multiple structure and it should be like the following (it's in PHP),

In my case i'm checking the user by its username.

$username = array( 'key' => 'username' ,  'value' => 'theUserName' );
$params = array( 'criteria' => array($username));

$server_url = $domain_name . '/webservice/rest/server.php' . '?wstoken=' . $token . '&wsfunction=' . $function_name;
$curl = new curl;
$rest_format = ($rest_format == 'json') ? '&moodlewsrestformat=' . $rest_format : '';

$resp = $curl->post($server_url . $rest_format, $params);

It worked for me in PHP, I'm sure in Java you can write a similar code.

Good luck

You have to pass the parameters as:

.....&criteria[0][key]=email&criteria[0][value]=aname@somedomain

With the ..... being the rest of the URL. Note [key] and [value] are an integral part of the call, they don't get dropped or replaced.

If you want to add more criteria then add:

.....&criteria[1][key]=email&criteria[1][value]=anothername@somedomain

 Note you also have to URL encode the string. I'm currently updating my Java library, MoodleRest, which you can download the source from GitHub (If you do, download on a regular basis as it is being updated very frequently as I am trying to catch up, it was a little out of date!)
