Question

I use oauth of google to access user data, and this is my function.

    public function actionOauth2callback(){
    $client_key = 'client-key-here';
    $client_secret = 'client-secret-here';
    $api_key = 'api-key';
    $redirect_uri = 'http://localhost:8888/proj/user/oauth2callback';

    if (!isset($_REQUEST['code']) && !isset($_SESSION['access_token'])) {
            // Print the below message, if the code is not received !
        echo "Please Authorize your account: <br />";
        echo '<a href = "https://accounts.google.com/o/oauth2/auth?client_id='. $client_key. '&redirect_uri='.$redirect_uri .'&scope=https://www.googleapis.com/auth/plus.me&response_type=code">Click Here to Authorize</a>';
    }
    else {
        if(!isset($_SESSION['access_token'])) {
          // Initialize a cURL session
            $ch = curl_init();

              // Set the cURL URL
              curl_setopt($ch, CURLOPT_URL, "https://accounts.google.com/o/oauth2/token");

              // The HTTP METHOD is set to POST
              curl_setopt($ch, CURLOPT_POST, TRUE);

              // This option is set to TRUE so that the response
              // doesnot get printed and is stored directly in 
              // the variable
              curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

              // The POST variables which need to be sent along with the HTTP request
              curl_setopt($ch, CURLOPT_POSTFIELDS, "code=" . $_REQUEST['code'] . "&client_id=" . $client_key . "&client_secret=" . $client_secret . "&redirect_uri=".$redirect_uri."&grant_type=authorization_code");

              // Execute the cURL request       
              $data = curl_exec($ch);

              // Close the cURL connection
              curl_close($ch);
              // Decode the JSON request and remove the access token from it
              $data = json_decode($data);

              $access_token = $data->access_token;

              // Set the session access token
              $_SESSION['access_token'] = $data->access_token;
        }
        else {
          // If session access token is set
            $access_token = $_SESSION['access_token'];
        }
        // Initialize another cURL session
        $ch = curl_init();

        // Set all the options and execute the session
        curl_setopt($ch, CURLOPT_URL, "https://gdata.youtube.com/feeds/api/users/default?v=2&access_token=" . $access_token);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
        $data = curl_exec($ch);
        curl_close($ch);
        // Get the data from the JSON response
        print_r($data);         
        $data = json_decode($data);
        print_r($data);
    }

But I have problem with format of data response, it’s not JSON or XML, just string like this

All Google Data APIs support JSON output through the use of the alt parameter You need to Look at Developer’s Guide: JSON / JavaScript

Your URL should look like this
