php CURL问题

本地wamp环境，配置虚拟机，demo.com。
两个控制器,想用TestA中的方法请求TestB中的方法，然后看到返回值。但是结果却不是我想要的。
哪位大神能帮我指出错误？？？不胜感激！！！

以下是代码

<code class="php">class TestA
{
    public function actionPost()
    {
        $url = 'dsp.com/Testb/Require_post';
        $data = array(
            'name' => 'ethan',
            'gender' => 'male',
        );
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_HEADER,1);  
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
        curl_setopt($ch, CURLOPT_POST,1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);      
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
    
        $result = curl_exec($ch); 
        curl_close($ch);      
        print_r($result);
    }
}


class TestB
{
    public function actionRequire_post()
    {
        $post = $_POST;
        print_r($post);
    }
}</code>

以下是返回结果
