多域名用同一个token

// 示例：Node.js中设置CORS头
const express = require('express');
const app = express();

app.use((req, res, next) => {
  res.header('Access-Control-Allow-Origin', '*');
  res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept, Authorization');
  next();
});

app.get('/api/data', (req, res) => {
  res.json({ message: 'Hello from server!' });
});

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

// 示例：使用JWT（JSON Web Token）并设置过期时间
const jwt = require('jsonwebtoken');

const token = jwt.sign({ userId: 123 }, 'secretKey', { expiresIn: '1h' });

console.log(token);

// 示例：设置cookie
res.cookie('authToken', 'yourTokenValue', {
  domain: 'example.com',
  path: '/',
  expires: new Date(Date.now() + 3600000), // 1小时过期
  httpOnly: true,
  secure: true
});
