求助 nodemailer 如何将用户提交的表单内容发送到指定邮箱

[sindy]

node.js 新手，求大神帮忙！！！！

想实现用户点击提交表单之后，将表单的内容以邮件的形式发送到指定的邮箱,
服务器端用 node.js ，发送邮件用 nodemailer 模块。
我的思路是给提交按钮绑定 submitData (),通过 xhr 发送到服务器，
在后台获取并替换 mailOptions 的 content 。

代码如下

sendmail.js

单独运行已经可以发送邮件，

var nodemailer = require ('nodemailer');
  var transporter = nodemailer.createTransport ({
    service: 'hotmail',
    auth: {
        user: '[email protected]',
        pass: '000000'
    }
});
var mailOptions = {
    from: '[email protected]', // sender address
    to: '[email protected]', // list of receivers
    subject: 'Hello', // Subject line
    text: 'Hello world', // plaintext body
    html: '<h1>Hello world </h1>' // content
};
transporter.sendMail (mailOptions, function (error, info ){
    if (error ){
        console.log (error );
    }else{
        console.log ('Message sent: ' + info.response );
    }
});

ajax

function submitData () {
    var xhr =creatXHR ();
    xhr.onreadystatechange = function () {
        if (xhr.readyState == 4 ) {
            if (xhr.status >= 200 && xhr.status < 300 ) || xhr.status == 304 )｛
alert (xhr.responseText );
} else {
    alert ("Request was unsuccessful:" + xhr.status );

        }
    }
};

xhr.open ("post","postexmple.js",ture );
xhr.setRequestHeader ('Content-Type',"application/x-www-form-urlencoded");
var form = documnet.getElementById ('user-info')
xhr.send (serialize (form ));
}
