【问题描述】：

我一直在尝试设置一个简单的表单，该表单将在提交时向用户发送电子邮件。我一直在使用 nodejs 并安装了 nodemailer 来帮助我。我使用 gmail 作为 SMTP 服务器，但遇到了一些问题。这是html：

<title> Schedule an Appointment - Name </title>
<link rel="stylesheet" type="text/css" href="public/styles.css">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<script src="public/script.js"></script>

<ul id="nav">
    <li><a href="page.html"> Home </a><br>
    <br>
    <li><a class="active" href=""> Appointment </a> <br>
    <br>
    <li><a href="specsPage.html"> Build </a> <br>
    <br>
    <li><a href="contactPage.html"> Contact </a> <br> 
    <br>
</ul>

<div id="schedulePage">
    <h4> Schedule an Appointment </h4>

    <div id="fullForm">

            First Name: <input id="firstname" type="text" name="firstname" placeholder="First Name..."> <br>
            <br>
            Last Name: <input id="lastname" type="text" name="lastname" placeholder="Last Name..."> <br>
            <br>
            Email: <input id="email" type="text" name="email" placeholder="Email..."> <br>
            <br>
            Phone Number: <input id="phone" type="text" name="phone" placeholder="Callback Number..."> <br>
            <br>
            <input id="send_email" type="submit" name="submit" value="Submit">
            <span id="message"></span>


    </div>
</div>

还有脚本：

$(document).ready(function(){
var from,to,subject,text;
$("#send_email").click(function(){      
    to=$("#email").val();
    firstname=$("#firstname").val();
    lastname=$("#lastname").val();
    $("#message").text("Sending E-mail...Please wait");
    $.get("http://localhost:4000/send",{to:to,subject:firstname,text:lastname},function(data){
    if(data=="sent"){
        $("#message").empty().html(" Email is been sent at " + to + " . Please check inbox !");
    }

    });
});

【解决方案1】：

首先，您需要在 Gmail 中启用不太安全的应用程序 How to enable less secure apps in google

然后安装 node-mailer

npm i nodemailer

将此函数粘贴到您的代码中

     var nodemailer = require('nodemailer');
    // create reusable transporter object using the default SMTP transport
    var transporter = nodemailer.createTransport('smtps://yourmail%40gmail.com:yourpass@smtp.gmail.com');

    // setup e-mail data with unicode symbols

function sendmail(to,subject,text,html,info) {

var mailOptions = {
    from: '"Testing Mail" <youmail@gmail.com>', // sender address
    to: to, // list of receivers
    subject: subject, // Subject line
    text: text, // plaintext body
    html: html  // html body
};
transporter.sendMail(mailOptions, function(error, infoo){
    var res={
        responsecode:''
    }
    if(error){
        res.responsecode=401;
        return info(new Error(res.responsecode),null);
    }
    res.responsecode=200;
    info(null,res.responsecode+infoo.response);
});}

现在调用函数

app.get('/send',function (req,res) {
//pass value from your html form here
sendmail('to', 'subject', 'body', '<h1>its Html</h1>', function (err, info) {
    if (err) {
        console.log("Error is " + err)
        return
    }
    console.log("Email sent. " + info)
})})
