Cake php ajax 布局缓存

Question

在任何 ajax 请求之后，所有后续的非 ajax 请求都以 ajax 布局而不是默认布局返回。

观察：

• 仅在生产环境中出现。
• 配置::write('Cache.disable', true); // 没有任何效果！
• 蛋糕版本 2.4.4
• 在 20 ~ 30 秒后呈现布局（默认）。
• config/core.php 相同。

我不知道为什么，我为此浪费了 8 个小时，有什么提示吗？

控制器（但任何控制器上的任何 ajax 都会导致问题：

<?php

App::uses('AppController', 'Controller');

class NewslettersController extends AppController
{

public $paginate = array(
    'limit' => 20,
    'paramType' => 'querystring',
    'order' => array(
        'Newsletter.created' => 'DESC'
    )
);

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

public function admin_index()
{
    $this->set('dataGrid', $this->paginate('Newsletter'));
}

public function admin_view($id = null)
{
    $this->Newsletter->id = $id;
    $result = $this->Newsletter->read();
    if (!$result) {
        $this->setFlashMessage('Cadastro não encontrado', 'error', array('action' => 'index'));
        return false;
    }

    $this->set('dataGrid', $result);
}

public function admin_delete($id = null)
{
    $this->Newsletter->id = $id;

    if (!$this->Newsletter->exists()) {
        $this->Session->setFlash('O item solicitado não foi encontrado!', 'alert_error');
        $this->setFlashMessage('O item solicitado não foi encontrado!', 'error', array('action' => 'index'));
    }

    try {
        if ($this->Newsletter->delete($id, false)) {
            $this->setFlashMessage('Item excluído com sucesso!', 'success', array('action' => 'index'));
        }
    } catch (Exception $e) {
        $this->setFlashMessage('Não foi possivel excluir este item pois existem itens atrelados a ele', 'error', array('action' => 'index'));
    }
}

public function admin_search()
{
    $this->autoRender = false;
    $conditions = null;
    if (isset($this->request->query['search']) && !empty($this->request->query['search'])) {
        $conditions[] = array(
            'OR' => array(
                'Newsletter.name LIKE' => '%' . $this->request->query['search'] . '%',
                'Newsletter.email LIKE' => '%' . $this->request->query['search'] . '%',
            )
        );
        $this->paginate['conditions'] = $conditions;
        $this->set('dataGrid', $this->paginate());
        $this->render('admin_index');
    }
}

public function push()
{

    if($this->Newsletter->save($this->request->data))
    {
        $response = array("result"=>true,"id"=>$this->Newsletter->id);
    }
    else
    {
        $response = array("result"=>false,"errors"=>$this->Newsletter->validationErrors);
    }

    return new CakeResponse(array("body" => json_encode($response),"type" => "json"));

}

}

?>

你必须在方法中区分ajax的布局，请在上面的代码中进行以下更改：

...
class NewslettersController extends AppController
{

   public layout = 'default';
...

   public function push() // if this is ajax function
   {
      $this->layout = 'ajax'; //put this for ajax functions only
      ....
   }

...
}

希望对你有帮助！
