function my_send_email($name,$email, $current_user, $status, $subject, $Message) {
    //most of the code here is from https://github.com/PHPMailer/PHPMailer/tree/master/examples

    require_once ABSPATH . WPINC . '/class-phpmailer.php'; 
    require_once ABSPATH . WPINC . '/class-smtp.php';

    // build message body`enter code here`
   $body = '
    <html>
        <body>
        <h1>My Email</h1>
        </body>
    </html>
    ';

    try {
        //Create a new PHPMailer instance
        $mail = new PHPMailer;

        //Tell PHPMailer to use SMTP
        $mail->isSMTP();

        //Enable SMTP debugging
        $mail->SMTPDebug = 2;

        //Ask for HTML-friendly debug output
        $mail->Debugoutput = 'html';

        //Set the hostname of the mail server
        $mail->Host = "mail.example.com";

        //Set the SMTP port number - likely to be 25, 465 or 587
        $mail->Port = 25;

        //Whether to use SMTP authentication
        $mail->SMTPAuth = true;

        //Username to use for SMTP authentication
        $mail->Username = "[email protected]";

        //Password to use for SMTP authentication
        $mail->Password = "1234";

        //Set who the message is to be sent from
        $mail->setFrom('[email protected]', 'sender_name');

        //Set an alternative reply-to address
        $mail->addReplyTo('[email protected]', 'alternative_contact_name');

        //Set who the message is to be sent to
        $mail->addAddress($email, $name);
        //Set the subject line
        $mail->Subject = 'PHPMailer SMTP test';
        //Read an HTML message body from an external file, convert referenced images to embedded,
        //convert HTML into a basic plain-text alternative body
        //$mail->msgHTML(file_get_contents(dirname(__FILE__) .'/contents.html'));
        $mail->MsgHTML($body);
        //Replace the plain text body with one created manually
        $mail->AltBody = 'This is a plain-text message body';

        $success=$mail->send();
        //send the message, check for errors
        if ($success) {
            return array('mailError' => false, 'message' => 'email sent! ' . $mail->ErrorInfo , 'body'=>$body);
        } else {
            return array('mailError' => true, 'message' => 'email error! ' . $mail->ErrorInfo , 'body'=>$body);
        }
    } catch (phpmailerException $e) {
        return array('mailError' => false, 'message' => 'email error! ' . $e->errorMessage() , 'body'=>$body);  //Pretty error messages from PHPMailer
    } catch (Exception $e) {
        return array('mailError' => false, 'message' => 'email error! ' . $e->getMessage() , 'body'=>$body); //Boring error messages from anything else!
    }

}

function my_register_endpoints(){
    register_rest_route(

        'my_namespace/v1',
        '/abc/',
        array(
            'methods' => 'POST',
            'callback' => 'my_end_point',
            'args' => array(
                    .....
            ),
            'permission_callback' => function (WP_REST_Request $request) {

                if(!is_user_logged_in()){
                .....
                }
                return true;

            }
        )

    );
}

add_action('rest_api_init','my_register_endpoints'); 

//endpoint
function my_end_point(WP_REST_Request $request){

        global $current_user;
        $sender = wp_get_current_user();
        $shortMsg=$request['shortMessage'];
        $subject="Some text";

        $email_resualt=my_send_email("reciver_name","reciver_email",$sender,$status,$subject,$shortMsg);

        if($email_resualt['mailError']==false){

            process.. $itemes, $item ..    
            $message='email sent!';
            return array('message' => $message,'items' => $items, 'item'=>$item);

        } else {

             return new WP_Error('email error',__('some message','email-error'),$request['id']);

        }   

}

我正在使用angularJS $ http.post调用API端点，电子邮件已发送，我可以在收件箱中看到它们，但是由于某些原因，我返回了未定义的响应：

Chrome控制台上的相关错误：1）SyntaxError：JSON位置0上的意外令牌S

2）TypeError：无法读取未定义的属性“ message”

我在客户端代码中使用response.message，但是如上所述，但是由于响应为空，因此出现错误。

我的WordPress PHP代码中还有其他端点，这些端点看起来相同，但不包括使用PHPmailer发送电子邮件，并且工作正常。甚至没有发送电子邮件功能的端点也可以正常工作。

我尝试调试了两天，但仍然不确定代码中的问题在哪里？

我发现了问题所在，在我的发送电子邮件功能中，出现了以下几行：

//启用SMTP调试

$ mail-> SMTPDebug = 2;

$ mail-> Debugoutput ='html';

似乎是因为在我注释了这两行之后，由于调试是从我的端点打开的，所以才匹配角度以进行处理，因此角度的响应结构良好，可以解析它。
