When doing my own node project geek tutorial, I need to develop a registration email activation function. This function is very common. When we register an account, there will definitely be this step. Let's take a look at how to implement this function.

1. Register an email address

First register an email address that supports sending verification emails. The one I registered here is NetEase’s 163 email address, so the 163 email address is used below. After successful registration, log in to the sending email address

, then click Settings on the navigation bar, select POP3/SMTP/IMAP, enable the POP3/SMTP/IMAP service, and set the authorization code.

2. Download the nodemailer plug-in

Enter on the command line: npm install --save nodemailer

3. Write and send Email code

3.1 Encapsulate the activation email code and export it:


//email.js

// 引入 nodemailer
const nodemailer = require('nodemailer');

// 创建一个SMTP客户端配置
const config = {
    host: 'smtp.163.com',
    port: 465,
    auth: {
      user: 'xxxx@163.com', //刚才注册的邮箱账号
      pass: 'xxxxxx' //邮箱的授权码,不是注册时的密码
    }
  };

// 创建一个SMTP客户端对象
const transporter = nodemailer.createTransport(config);

// 发送邮件
module.exports = function (mail){
  transporter.sendMail(mail, function(error, info){
    if(error) {
      return console.log(error);
    }
    console.log('mail sent:', info.response);
  });
};
Copy after login

3.2 Test:


//sendtest.js

var send = require('./email.js');


// 创建一个邮件对象
var mail = {
  // 发件人
  from: &#39;极客教程 <xxxx@163.com>&#39;,
  // 主题
  subject: &#39;[极客教程]激活邮箱账号&#39;,
  // 收件人
  to: &#39;xxxx@qq.com&#39;,
  // 邮件内容,HTML格式
  text: `尊敬的${user.name},您好!点击链接即可激活您的极客教程
      网账号,http://localhost:3000/checkCode?name=${user.name}&code=${user.code}为保障您的帐号安全,请在24小时内点击该链接,您也可以将链接复制到浏览器地址栏访问。 若如果您并未尝试修改密码,请忽略本邮件,由此给您带来的不便请谅解。本邮件由系统自动发出,请勿直接回复!` //接收激活请求的链接
};
send(mail);
Copy after login

If successful, you can see the message sent in the test mailbox.


4. Verification steps

Let’s briefly talk about how to implement email verification.

1. In the database user data structure you define, there must be fields such as activation code, expiration time, and whether it has been activated, which are used to judge during activation;


{
  code: String, //激活码,格式自己定义
  date: Number, //过期日期,过期后不能激活
  islive: Boolean //判断是否激活
}
Copy after login

2 . Send an activation link containing the username and activation code, as follows:


// 创建一个邮件对象
var mail = {
  // 发件人
  from: &#39;极客教程 <xxxx@163.com>&#39;,
  // 主题
  subject: &#39;[极客教程]激活邮箱账号&#39;,
  // 收件人
  to: &#39;xxxx@qq.com&#39;,
  // 邮件内容,HTML格式
  text: `尊敬的${user.name},您好!点击链接即可激活您的极客教程
      网账号,http://localhost:3000/checkCode?name=${user.name}&code=${user.code}为保障您的帐号安全,请在24小时内点击该链接,您也可以将链接复制到浏览器地址栏访问。 若如果您并未尝试修改密码,请忽略本邮件,由此给您带来的不便请谅解。本邮件由系统自动发出,请勿直接回复!` //接收激活请求的链接
};
send(mail);
Copy after login

3 . Respond to the activation request, based on the user's activation link Search by name, if the user exists, determine whether the activation code is consistent, and determine whether the activation code has expired. If all are correct, change the activation status. At this time, the activation is successful, as follows:


// check email code
exports.checkCode = function (req, res){
  var username = req.query.name;
  var code = req.query.code;
  User.findOne({name: username}, function (err, user){
      if (user.code === code && (user.date - Date.now()) > 0){
          User.update({name: username}, {islive: true}, function (err){
              if (err){
                  res.json({error: true})
              }else{
                  console.log(user)
                  res.json({ok: true})
              }
          });
      }else{
        res.json({
          email: user.mail,
          failure: true
        })
      }
  });
}
Copy after login

5. Problems encountered

The following problems were encountered during development:

{ [AuthError: Invalid login - 535 Error: authentication failed]
name: 'AuthError',
data: '535 Error: authentication failed',
stage: 'auth' }

smtp server verification failed because NetEase Your email has authorization restrictions, so be sure to check the account number and authorization code you used when registering your email.
