解析 multipart/form-data cakephp 3

Question

我目前正在尝试解析我在 Chrome 中通过 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"

------WebKitFormBoundarymsXhoqlRBbTbsZFb
Content-Disposition: form-data; name="description"

当我尝试调试 $this->request->input() 时，我得到了这个输出。当我尝试 $this->request->input('json_decode') 时，我得到一个空数组，所以我假设数据的格式不正确（只是一个字符串）。在我编写自己的算法之前，我想确定我不会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，路由过程似乎以某种方式提前清空了 post 数组。当我尝试使用以下端点 http://vecto.app/api/pictures $this->request->data is empty. However, when I try to access the endpoint http://vecto.app/pictures 的 Postman 时，$this->request->data 中填充了信息。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');
 });

Answer 1

我终于找到了解决方案，它是清空 $this->request->data 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); 
        }); 
    } 
}
