Slim v2未定义变量

Question

我在slim framework v2中编写了一个用于身份验证的中间件。

这里是教程：http://docs.slimframework.com/routing/middleware/#what-arguments-are-passed-into-each-route-middleware-callable

$app->get('/cases/shared/group/:group_id', 'authenticate', $authenticate2($app->router()->getCurrentRoute(), 'member', 'group'), function ($group_id) use ($app) { 
    $limit = $app->request()->params('limit'); 
    $offset = $app->request()->params('offset'); 
    $search = $app->request()->params('search'); 
    $order = $app->request()->params('order'); 

    $objCases = new Cases(); 
    $result = $objCases->getSharedWithGroupCases($group_id, $limit, $offset, $search, $order); 

    if ($result === null) { 
     $response["error"] = true; 
     $response["message"] = _("İlgili grup ile paylaşılan olgu bulunmamaktadır."); 
    } else { 
     $response["error"] = false; 
     $response["data"] = $result; 
     $response["total_data"] = $objCases->getNumOfSharedWithGroupCasesData($group_id, $search, $order); 
    } 

    echoResponse(200, $response); 
}); 

认证。 ：

function authenticate(\Slim\Route $route) { 
    $headers = getallheaders(); 
    $response = array(); 
    $app = \Slim\Slim::getInstance(); 

    if (isset($headers['Authorization'])) { 
     if(strpos($headers['Authorization'], '.') !== false) { 
      $authorization = explode('.', $headers['Authorization']); 
      $api_key = $authorization[0]; 
      $user_id = $authorization[1]; 

      $objUsers = new Users(); 
      if ($objUsers->isValidUser($user_id, $api_key) <= 0) { 
       $response["error"] = true; 
       $response["message"] = "Access Denied. Invalid Api key"; 
       echoResponse(401, $response); 
       $app->stop(); 
      } 
     } else { 
      $response["error"] = true; 
      $response["message"] = "Access Denied. Invalid Api key"; 
      echoResponse(401, $response); 
      $app->stop(); 
     } 
    } else { 
     $response["error"] = true; 
     $response["message"] = "Api key is misssing"; 
     echoResponse(400, $response); 
     $app->stop(); 
    } 
} 

$authenticate2 = function (\Slim\Route $route, $role, $where) { 
    $response["group_id"] = $route->getParam('group_id'); 
    $response["role"] = $role; 
    $response["where"] = $where; 

    echoResponse(200, $response); 
}; 

第一种认证方法效果很好。但第二身份验证方法返回两个错误：

未定义的变量：authenticate2

功能名称必须是一个字符串

错误行：$app->get('/cases/shared/group/:group_id', 'authenticate', $authenticate2($app->router()->getCurrentRoute(), 'member', 'group'), function ($group_id) use ($app) {

我怎么能发送路由和参数一起中间件？

Answer 1

确保$authenticate2 = function();代码在$app->get('/cases/shared/group/:group_id', …调用之前执行。
