Yii2 Rest Authentication Bearer Post Data missing

Question

I'am working on a REST API. Therefore I prepared a function which sends the authentication data via curl to the REST Server. I've implemented two authentication options. The first is Basic Authentication, the second is authentication via token (Bearer).

Now, i'am in trobles, because at the REST Server, the POST Data is not received by the REST Server in case of authentication via token. The authentication itself is working, but the POST Data is going to be lost. In case of authentication via Basis Authentication, the POST Data will be received by the REST Server, no problem.

private function request($postdata){

    $url = $this->service_url_private;
    $curl = curl_init($url);
    $curl_post_data = $postdata;


    // check if token authentication is used
    if (array_key_exists('token', $postdata )){
        $token = $postdata['token'];
        $authorization = 'Authorization: Bearer ' . $token;
        // prepare curl for Bearer Token Authorization
        curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/json' , $authorization));
    } else {
        // otherwise use BASIC authentication
        if (array_key_exists('email', $postdata )){
            $username = $postdata['email'];
        }
        if (array_key_exists('password', $postdata )){
            $password = $postdata['password'];
        }
        // prepare curl for Basic Authentication
        curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
        curl_setopt($curl, CURLOPT_USERPWD, "$username:$password");
    }

    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data);
    curl_setopt($curl, CURLINFO_HEADER_OUT, true); // Detail information for debugging
    curl_setopt($curl, CURLOPT_VERBOSE,true);
    $curl_response = curl_exec($curl); // Detail information for debugging
    $info = curl_getinfo($curl); // Detail information for debugging
    curl_close($curl);
    var_dump($info);
    return $curl_response;
}

In addition, $curl_post_data is showing all the data by the client while debugging, before the rest call will be executed with curl_exec($curl).

What could be the problem?

Answer 1

After lots of hours I found the problem and the solution for this problem.

The problem is:

curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/json' , $authorization));

Using 'Content-Type: application/json' results in loosing the POST data information.

Solution for this is:

change

'Content-Type: application/json' 

to

'Content-Type: application/x-www-form-urlencoded'
