使用jquery ajax发布到CakePHP控制器

Question

I want to post data to a controller in CakePHP, but posting with JQuery always results in"POST http//localhost/SA/myController/editUserData/1 400 (Bad Request)" error and I can't figure out why.

In my view I have the following method, that posts the data to the controller page

   $scope.saveUser = function() {
    $.ajax({
        type: 'POST',
        url: '<?php echo Router::url(array(
                                        'controller' => 'myController',
                                        'action' => 'editUserData',
                                        0 => $userInfo['user']['id'],));?>',
        data: { email: 'cabraham@delhi.k12'},//"my edited data for example"
        success: function (data) {
          alert(data);
        }
    });

My controller method looks like this:

  public function editUserData($id) {
       if($this->request->is('post') || $this->request->is('put')) {
           $this->AcsaUser->save($this->request->data('email'));//edit and save the new data
           echo 'ok';
       }
   }

Any ideas??

Two things that may be throwing it.

(1) Cake's built-in security - so exempt the method from it:

In AppController.php

public function beforeFilter() {
    $this->Security->unlockedActions = array('editUserData')
}

(2) Decide how you want your editUserData method to render the view, if you're echo'ing out an 'ok' it will still pull in the default layout and look for an editUserData.ctp in the view (and cause an error if it doesn't find the file), so

To not render anything, ie a .ctp view file and the default layout.. in the editUserData($id), add

$this->autoRender = false;

To only render the view file and not the layout:

$this->autoLayout = false;

......Then lastly I wound just add this parameter in the ajax call :

dataType : 'html' // (or JSON?)
