我目前正在尝试解析我通过Chrome中的Postman插件发送的multipart/form-data。但是，我得到以下输出：

'------WebKitFormBoundarymsXhoqlRBbTbsZFb
Content-Disposition: form-data; name="album_id"

当我尝试调试$this->request->input()时，我会得到此输出。当我尝试$this->request->input('json_decode')时，我得到一个空数组，所以我假设数据不是正确的格式（只是一个字符串）。在我编写自己的算法之前，我想确保我没有用这个重新发明轮子。我做错了什么？或者如果没有，是否存在一些Cakephp 3函数来处理这个问题？

更新
我发现我的代码有什么问题，似乎路由过程以某种方式将post数组清空。当我尝试Postman时，以下端点http://vecto.app/api/pictures $ this-＆gt; request-＆gt;数据为空。但是，当我尝试访问端点http://vecto.app/pictures时，$ this-＆gt; request-＆gt;数据将填充信息。有谁知道以下路由设置有什么问题：

Router::prefix('api', function ($routes) {
   $routes->extensions(['json', 'xml']);
   $routes->resources('Users');
   $routes->resources('Pictures');
   // We connect the /register action so we can simply extend the CRUD    Plugin add() method 
   // and benefit of already available logic like validation and response codes instead of having to reinvent the wheel.
   Router::connect('/api/users/register', ['controller' => 'Users',   'action' => 'add', 'prefix' => 'api']);
   $routes->fallbacks('InflectedRoute');
 });

我终于找到了解决方案，它是一个清空$ this-＆gt; request-＆gt;数据数组的beforeFilter。因此，输入数组不为空，但数据数组为空。这是导致问题的代码：

public function beforeFilter(Event $event) { 
    if ($this->request->is('post')) { 
        $data = $this->request;
        $this->request->data = $this->request->input(function ($data) { 
            return json_decode($data, true); 
        }); 
    } 
}
