如何使用req.body和node-cron调度电子邮件

npm install express nodemailer node-cron

const express = require('express');
const nodemailer = require('nodemailer');
const cron = require('node-cron');

const app = express();

app.use(express.json());
app.use(express.urlencoded({ extended: false }));

app.post('/schedule-email', (req, res) => {
  // 解析请求体中的数据
  const { to, subject, text, schedule } = req.body;

  // 创建一个定时任务
  cron.schedule(schedule, () => {
    // 创建一个Nodemailer传输对象
    const transporter = nodemailer.createTransport({
      service: '腾讯企业邮',
      auth: {
        user: 'your-email@example.com',
        pass: 'your-password'
      }
    });

    // 配置电子邮件选项
    const mailOptions = {
      from: 'your-email@example.com',
      to: to,
      subject: subject,
      text: text
    };

    // 发送电子邮件
    transporter.sendMail(mailOptions, (error, info) => {
      if (error) {
        console.log(error);
      } else {
        console.log('Email sent: ' + info.response);
      }
    });
  });

  res.send('Email scheduled successfully');
});

// 启动服务器
app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

node app.js

{
  "to": "recipient@example.com",
  "subject": "Scheduled Email",
  "text": "This is a scheduled email",
  "schedule": "*/5 * * * *"
}
