解析多部分/表單數據cakephp 3

Question

我目前正試圖解析通過Postman插件在Chrome中發送的multipart/form-data。不過，我得到以下輸出：

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

2 
------WebKitFormBoundarymsXhoqlRBbTbsZFb 
Content-Disposition: form-data; name="description" 

haiahaahahahdaisdhisadhisadihsdhiiahsd 
------WebKitFormBoundarymsXhoqlRBbTbsZFb 
Content-Disposition: form-data; name="favorite" 

true 
------WebKitFormBoundarymsXhoqlRBbTbsZFb 
Content-Disposition: form-data; name="uploadfile"; filename="test2.txt" 
Content-Type: text/plain

此輸出做我得到的，當我嘗試調試$this->request->input()。當我嘗試$this->request->input('json_decode')時，我得到一個空數組，所以我假定數據的格式不正確（只是一個字符串）。在我編寫自己的算法之前，我想確保我不會用這個算法重新發明輪子。我做錯了什麼？或者，如果沒有，是否存在一些CakePHP 3功能來處理這個問題？

更新
我發現什麼是錯在我的代碼，它似乎像路由過程莫名其妙清空後陣列提前。當我嘗試使用以下端點的郵遞員http://vecto.app/api/pictures $ this-> request-> data是空的。但是，當我嘗試訪問端點http://vecto.app/pictures時，$ this-> request->數據充滿了信息。有誰知道什麼是錯用下面的路由設置：

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

我終於發現這是掏空$這個 - >請求 - >數據數組的beforeFilter的解決方案。因此，輸入數組不是空的，但數據數組是空的。這是導致問題的代碼：

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); 
     }); 
    } 
}
