POST request XML with CakePHP

我正在尝试使用 CakePHP 2.3.8 对 XML 数据发出 POST 请求，但我遇到了一些问题，我认为它正在处理授权。首先，我要做的是使用来自控制器中操作的 XML 数据发出 POST 请求。发出此 post 请求的操作应该在数据库中保存一个条目，这样我就知道 POST 请求已成功触发。什么都没有被拯救。

下面是两个操作和前面的筛选器。我确保允许访问之前过滤器中的每个操作。xml_post是我访问的触发 XML post 请求的操作，receive_xml操作是在收到某些内容时应在数据库中保存条目的操作。

public function beforeFilter() {
    parent::beforeFilter();
    $this->Auth->authorize = 'Controller';  
    $this->Auth->allow = array('*');
}
public function xml_post_test(){
    $data = array(
        'post' => array(
            'id' => 1,
            'title' => 'This is a test',
            'body' => 'Here is something for the body '
        )
    );
    App::uses('HttpSocket', 'Network/Http');
    $http = new HttpSocket();
    $xml_data = Xml::fromArray($data);
    $xml_string = $xml_data->asXML();
    $response = $http->post('http://localhost/tests/receive_xml', $xml_string);
    debug($response);
}
    //save an arbitrary entry in the database a POST request is received (just checking that the xml_post_test method is working
public function receive_xml(){
        if($this->request->is('post')){
            $this->loadmodel('TestTable');
            $this->TestTable->create();
            $this->TestTable->save(array('id' => '','data' => 'abc 123'));
        }
}

这是响应（调试）
