我想要苗条2项目转换苗条3。 我正在stuking一个问题。苗条2到苗条3方法错误

当我打电话给我的方法: http://localhost:8000/task_manager/v1/tasks

我得到了一个错误:

Catchable fatal error: Argument 1 passed to authenticate() must 
be an instance of Slim\Route, instance of 
Slim\Http\Request given in 
C:\wamp64\www\task_manager\v1\index.php on line 42. 

我怎么能解决这个问题?一些帮助将不胜感激。

这里是我的PHP代码:

$app = new \Slim\App(); 
... 
... 

function authenticate(\Slim\Route $route) { 
    // Getting request headers 

    $headers = apache_request_headers(); 
    $data = array(); 
    $app = AppContainer::getInstance(); 

    // Verifying Authorization Header 
    if (isset($headers['Authorization'])) { 
     $db = new DbHandler(); 

     // get the api key 
     $api_key = $headers['Authorization']; 
     // validating api key 
     if (!$db->isValidApiKey($api_key)) { 
      // api key is not present in users table 
      $data["error"] = true; 
      $data["message"] = "Access Denied. Invalid Api key"; 
      return echoRespnse(401, $data, $response); 
      //$app->stop(); 
      return $response->withStatus(401)->withBody("Bad Request"); 
     } else { 
      global $user_id; 
      // get user primary key id 
      $user_id = $db->getUserId($api_key); 
     } 
    } else { 
     // api key is missing in header 
     $data["error"] = true; 
     $data["message"] = "Api key is misssing"; 
     return echoRespnse(400, $data, $response); 
    } 
} 


$app->get('/tasks', function (Request $request, Response $response) { 
      global $user_id; 
      $data = array(); 
      $db = new DbHandler(); 

      // fetching all user tasks 
      $result = $db->getAllUserTasks($user_id); 

      $data["error"] = false; 
      $data["tasks"] = array(); 

      // looping through result and preparing tasks array 
      while ($task = $result->fetch_assoc()) { 
       $tmp = array(); 
       $tmp["id"] = $task["id"]; 
       $tmp["task"] = $task["task"]; 
       $tmp["status"] = $task["status"]; 
       $tmp["createdAt"] = $task["created_at"]; 
       array_push($data["tasks"], $tmp); 
      } 

      return echoRespnse(200, $data, $response); 
     })->add('authenticate');

既然你不是在你的'身份验证的任何地方使用'$ route'()'函数,只是改变了'身份验证(\ Slim \ Route $ route)'''authenticate(Request $ request,Response $ response)''。 –

如果你这样做,你可以删除'apache_request_headers()'并使用Slim的Request类来获取它们:https://www.slimframework.com/docs/objects/request.html –

谢谢。我想你确定。这是解决我的问题的一个选择。 –

在Slim2你可以添加中间件这样的:

<?php 
$aBitOfInfo = function (\Slim\Route $route) { 
    echo "Current route is " . $route->getName(); 
}; 

$app->get('/foo', $aBitOfInfo, function() { 
    echo "foo"; 
}); 

这是不可能的slim3:第一中间件必须与add方法添加像这样:

$app->get('/foo', function() { 
    echo "foo"; 
})->add($aBitOfInfo); 

其次中间件没有\Slim\Route - 作为第一个参数的对象。 这些不是Request,Response和下一个中间件的可调用。因此,这应该是这样的:

/** 
* Example middleware closure 
* 
* @param \Psr\Http\Message\ServerRequestInterface $request PSR7 request 
* @param \Psr\Http\Message\ResponseInterface  $response PSR7 response 
* @param callable         $next  Next middleware 
* 
* @return \Psr\Http\Message\ResponseInterface 
*/ 
$aBitOfInfo = function ($request, $response, $next) { 
    $response->getBody()->write('BEFORE'); 
    $response = $next($request, $response); 
    $response->getBody()->write('AFTER'); 

    return $response; 
};
