访问发送到Auth.redirect的发布数据

Question

我在Cakephp 2.5.3中遇到了Auth.redirect功能的问题。以下是场景：

方案

有一个受登录保护的操作（controller =＆gt; TalkComments，action =＆gt; add）。使用POST HTML方法将数据提交给此操作。 现在，如果用户未登录，则用户需要登录视图。用户登录后，会成功将用户重定向到所需的控制器和操作。 问题是，它也没有发送POST数据，因为没有执行add（）函数。

如何让Auth.redirect也存储我的帖子数据，并在调用redirectUrl后发送它。

以下是我的代码：

UsersController.php

class UsersController extends AppController {

//put your code here

public function beforeFilter() {
    parent::beforeFilter();
    $this->Auth->allow('add', 'login');
}

public function login() {
    if ($this->request->is('post')) {
        if ($this->Auth->login()) {
            return $this->redirect($this->Auth->redirectUrl());
        }
        $this->Session->setFlash(__('Invalid username or password, try again'));
    }
}

public function logout() {
    return $this->redirect($this->Auth->logout());
}
public function isAuthorized() {
    return true;
}
}

TalkCommentsController.php

class TalkCommentsController extends AppController {

//put your code here
public function add() {
    if ($this->request->is('post')) {
        $this->TalkComment->create();
        if ($this->TalkComment->save($this->request->data)) {
            $this->Session->setFlash(__('Comment Saved'));
            return $this->redirect($this->referer());
        }
        $this->Session->setFlash(__('Could not post comment'));
    }
}

public function isAuthorized() {
    return true;
}
}

如果我还需要其他任何东西，请告诉我。

提前致谢：）

使这项工作正常的唯一方法是使用会话组件！

在获得身份验证之前，AuthComponent不允许您访问添加操作。所以我们将在AppController中使用beForeFilter函数，就像右边here所记载的那样，如下所示：

  public function beforeFilter() {
    //i used strtolower function the test is a case sensitive & i do not know the output of $this->params['controller'] and $this->params['action'] in your application but in this case it will work fine !
    if((strtolower($this->params['controller']) == 'talkcomments') && (strltolower($this->params['action']) == 'add') && ($this->is('post')){
       //do not forget to use Session Component in AppController before to use!
       $this->Session->write('data',$this->data);   
    }
  }

现在是时候使用我们的Session存储数据来自动添加记录了！

  public function login() {

    if ($this->request->is('post')) {
      if ($this->Auth->login()) {
        $comment = $this->Session->read('data');
        if(isset($comment) && !empty($comment)){
          $this->loadModel('TalkComment');
          $this->TalkComment->set($comment);
          if($this->TalkComment->validate()){
            if($this->TalkComment->save($comment))
              $this->Session->setFlash(__('Comment Saved'));
            else
              $this->Session->setFlash(__('Could not post comment'));
          }
          else
            $this->Session->setFlash(__('Could not post comment'));
        }
        return $this->redirect($this->Auth->redirectUrl());
      }
      $this->Session->setFlash(__('Invalid username or password, try again'));
    }
  }

这对你来说应该是一种魅力。

如果您只有一个Add，则需要进行如下所示的DynamicAdd操作：

private function DYnamicAdd($model, $data, $success_message, $error_message){
  $record = $data;
    if(isset($record) && !empty($record)){
      App::uses($model,'model');
      $this->$model->set($record);
      if($this->$model->validate()){
        if($this->$model->save($data))
          $this->Session->setFlash($success_message);
        else
          $this->Session->setFlash($error_message);
      }
      else
        $this->Session->setFlash($error_message);
}

我们举一个例子：

我们假设我们有两个带有add方法的控制器，TestOnesController，TestTwosController！然后登录方法将是这样的

public function login(){
  if ($this->request->is('post')) {
    if ($this->Auth->login()) {

      //in the case of TestOnesController
      $this->DynamicAdds('TestOne', $this->Session->read('TestOne'), 'Testone Saved', 'Could not post Testone');

      //in the case of TestTwosController
      $this->DynamicAdds('TestTwo', $this->Session->read('TestTwo'), 'Testtwo Saved', 'Could not post Testtwo');

      return $this->redirect($this->Auth->redirectUrl());
    }
    $this->Session->setFlash(__('Invalid username or password, try again'));
  }
}

在AppController的beforeFilter操作中！

还在会话中使用动态写作：

public function beforeFilter(){
  //C1 C2 C3 C4 are the controllers you may have a Add method in
  if(in_array(strtolower($this->params['controller']), array('C1','C2','C3','C4')) && (strltolower($this->params['action']) == 'add') && ($this->is('post')){
   //ucfirst and singularize to extract the name of the model from controller name !
   $this->Session->write(ucfirst(Inflector::singularize($this->params['controller'])),$this->data);   
}
}
