Authentication

Hi all,

I am using plugin : https://moodle.org/plugins/auth_userkey

To get user login URL, It's working fine for me But issue I am facing to redriect.

Please help me.

function getloginurl(){
	require_once('curl.php');
	$domainname = 'https://yourdomain.com/moodle'; //paste your domain here
	$wstoken = 'a9d61f9e8c1dec3a3b956adcb8d99862'; //here paste your enrol token 
	$wsfunctionname = 'auth_userkey_request_login_url';
	$username = 'admin';    // For demo I put here hardcoded admin as username.
	if(!empty($username)){
		$enrolment = array( 'username' => $username );
		$params = array( 'user' => $enrolment );
		//header("Content-Type:text/plain");
		$serverurl = $domainname . "/webservice/rest/server.php?wstoken=" . $wstoken . "&wsfunction=" . $wsfunctionname;
		$curl = new curl;
		//curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
		//curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: text/plain'));
		$restformat = '';
		$restformat = ($restformat == 'json')?'&moodlewsrestformat=' . $restformat:'';
		$resp = $curl->post($serverurl . $restformat, $params);
		return $resp;exit();
	}

}
redirect(getloginurl());

redirect not working it's take me home page without login.

But print it then given me link to login.

like echo getloginurl();
