Cakephp ajax post 请求出错

Question

我在 Cakephp 中有一个由 ajax 请求加载的表单。通过另一个 ajax 请求发送表单后，魔术在控制器中完成，控制器正在发回新的 html 代码。到目前为止，一切都很好。只要我发送一个获取请求，它就可以很好地工作。如果我更改 ajax 脚本以强制执行 post 请求，结果是黑洞。我阅读了很多有关安全组件的内容，并尝试更改了很多内容，但都没有用。

这是我的"OffersController.php"代码：

App::uses('AppController', 'Controller');
App::uses('Folder', 'Utility');
App::uses('File', 'Utility');


class OffersController extends AppController {

public $components = array('Paginator');


public function beforeFilter() {
    parent::beforeFilter();
    $this->Auth->allow('createform');
    $this->Security->unlockedActions = array('createform');
}


public function createform() {
    $this->request->onlyAllow('ajax'); // No direct access via browser URL
    //$this->autoRender = 'false; // We don't render a view in this example
    $this->Security->validatePost = false;
    if ($this->request->is('post')) {
        $this->Session->setFlash(__('Post sent.').' <tt class="pull-right">(C:Offers, F:createform, A:2)</tt>', 'default', array('class' => 'alert alert-success'));
    } else {

    }

    $this->layout = false;
    $this->render('offerform');
}

}

这是将通过 ajax 加载的 "createform.ctp"（如果页面已加载，然后发送 ajax 请求：

        <div class="container">
        <div class="row">
            <div class="col-lg-12 text-center">
                <h2 class="section-heading">Offerte</h2>
                <h3 class="section-subheading text-muted">Fordere unverbindlich eine Offerte an.</h3>

这是我的模特"Offer.php":

class Offer extends AppModel {
public $name = 'Offer';

}

感谢您的帮助和提示。有什么想法吗？

Answer 1

将以下内容添加到 beforeFilter

if ($this->action === 'create form') {
    $this->Security->validatePost = false;
    $this->Security->csrfCheck = false;
}

这应该可以解决您的问题

Answer 2

我不得不更改此行

//$("#btnSave").click(function(e){
$("#ajaxForm").submit(function(e){

在第一个版本（上面的主要问题）中，我使用了#btnSave，现在我尝试使用注释行#ajaxForm。现在可以了。我不知道为什么我在第一个版本中没有使用这一行。不过现在问题已经解决了。

Answer 3

试试这个

 public function edit_comment() {
        $this->layout = 'ajax';
        $this->autoRender = false;
        if ($this->request->is('ajax')) {
            if ($this->FaComment->save($this->request->data, false)) {
                $response['status'] = 'success';
                $response['action'] = 'edit_comment';
                $response['data'] = $this->request->data['FaComment'];
                $response['message'] = __d('vanderdeals', 'Comment saved successfully');
        } else {
            $response['status'] = 'error';
            $response['model'] = 'FaComment';
            $response['message'] = __d('vanderdeals', 'Internal server error occurred. Please try again later.');
        }

        echo json_encode($response);
    }
}
