应用程序授权后Facebook重定向到画布URL而不是画布页面

当有人访问尚未授权该应用的画布页面时,我从this post获得了帮助,以了解如何重定向到Facebook授权页面。

现在,我希望在用户授权后,FB会重定向到画布页面(https://app.facebook.com/myapp)。但它正在重定向到画布网址(https://myhostingapp.com/game.php?..。)

这是预期的,还是我们可以采取任何措施来控制它。如何在授权后告诉API重定向到画布页面?

现在我可以考虑使用$ _SERVER [HTTP_REFERER]来查看我是否来自授权页面,如果是,则将页面重定向到画布页面。但我希望有更好的方法可以做到这一点

Canvas网址代码:

if (Config::$fbAvailalbe){ //see below how this variable is derived
    echo "fb is available";
    $facebook = new Facebook(array(
      'appId'  => Config::$appId,
      'secret' => Config::$appSecret,
    ));

    $user = $facebook->getUser();

    if ($user) {
        echo "app installed";
      try {
        // Proceed knowing you have a logged in user who's authenticated.
        $profile = $facebook->api('/me');
      } catch (FacebookApiException $e) {
        error_log($e);
        $user = null;
      }
    }

    if (!$user) {
      echo " app not installed gonna redirect"; 
      $scope = "scope=email,read_stream,read_friendlists,publish_stream";
      $redirect = $facebook->getLoginUrl(
                    array(
                        'canvas' => 1,
                        'fbconnect' => 0,
                        'req_perms' => $scope
                        )
                    );
      echo '<script>top.location="' . $redirect . '";</script>';
      exit();
      //header("Location: $redirect".$scope);
    } 

    if ($profile){
        $firstName = $profile['first_name'];
        $sid = $profile['id'];
        var_dump($profile);
    }else{
        echo "unable to get profile";
    }

}else{

    echo "fb unavailable, using dmmy";
    $firstName = "Dummy Name";
    $sid = Config::$testsid;

}

来自Config.php的Snipet

    //this is to derive the $fbAvailable variable
    //we get this condition satisfied when we run the page runs from fb canvas 
    if (isset($_SERVER['HTTP_REFERER'])){

        if (substr_count($_SERVER['HTTP_REFERER'],'apps.facebook.com')){
            self::$fbAvailalbe = 1;
        }
    }

检查文档here

代码中的两个错误

错误#1:

$scope = "scope = email,read_stream,read_friendlists,publish_stream";

错误#2:

根据文档here(如现在)

req_params是'范围'

不确定'canvas'和'fbconnect'参数可能会被忽略,因为它们不再受支持

$redirect = $facebook->getLoginUrl(
                    array(
                        'scope' => $scope,
                        'redirect_uri' => 'https://app.facebook.com/myapp'
                        )
                    );
