php - 我怎样才能访问 POST 数据，然后在 CakePHP 中将其删除？

Question

我正在构建一个连接到我的远程服务器的 Android 应用程序。我允许用户添加新内容，但在允许添加之前还必须对他们进行身份验证。这是他们添加的示例:

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair(SharedVariables.TAG_NAME, name));
params.add(new BasicNameValuePair(SharedVariables.TAG_ADDRESS, address));
params.add(new BasicNameValuePair(SharedVariables.TAG_TYPE, type));
params.add(new BasicNameValuePair(SharedVariables.TAG_DESCRIPTION, description));
params.add(new BasicNameValuePair(SharedVariables.TAG_DIFFICULTY, difficulty));
params.add(new BasicNameValuePair(SharedVariables.TAG_TERRAIN, terrain));
params.add(new BasicNameValuePair(SharedVariables.TAG_LONG, Double.toString(currentLng)));
params.add(new BasicNameValuePair(SharedVariables.TAG_LAT, Double.toString(currentLat)));
params.add(new BasicNameValuePair(SharedVariables.TAG_UID, Integer.toString(2)));

//Retrieve hash and id to identify authenticate user
UserAuth auth = new UserAuth(AddSpot.this);
HashMap<String,String> session = auth.getUserDetails();
params.add(new BasicNameValuePair(SharedVariables.TAG_UID, session.get("id")));
params.add(new BasicNameValuePair(SharedVariables.TAG_HASH, session.get("hash")));

如您所见，在第一部分中，我存储了用户自己添加的内容，但是，我还传递了用户 ID，然后将 token /哈希传递到 POST 数据中，如在最后部分。我的问题是，我不想使用 $this->Location->save($this->request->data) 将所有内容添加到数据库表中。相反，我希望能够挑选出用户 ID 和哈希并将其删除，然后保存所有其他内容。我如何在 CakePHP 中执行此操作？

这是我现在在 CakePHP 中的方法:

function add()
{               
    if ($this->request->is('post'))
    {
        $response = array();
        $this->loadModel('User');
        if($this->User->validateHash($id, $hash))
        {   
            //Do some logic to remove id and hash from request

            $this->Location->create();
            //Save data from POST
            if ($this->Location->save($this->request->data))
            {
                //Successfully saved
                $this->response->statusCode(200);
            } 
            else
            {
                //Error in saving
                $this->response->statusCode(500);
            }
        }
        else 
        {
            //Does their hash match? No, then they are unauthorized to add
            $this->response->statusCode(401);
        }
    }
    $this->set(compact('response'));
    $this->set('_serialize', array('response'));
}

这个？

unset($this->request->data['YourModel']['id']);
unset($this->request->data['YourModel']['hash']);
