如何在Authorization报头中将带有fetch和cors的JWT令牌发送到Express服务器？

fetch('http://your-express-server.com/api/endpoint', {
  method: 'GET',
  headers: {
    'Authorization': 'Bearer your-jwt-token',
    'Content-Type': 'application/json'
  }
})
.then(response => response.json())
.then(data => {
  // 处理返回的数据
})
.catch(error => {
  // 处理错误
});

const express = require('express');
const jwt = require('jsonwebtoken');

const app = express();

app.use(express.json());

app.use((req, res, next) => {
  const token = req.headers.authorization.split(' ')[1]; // 获取JWT令牌
  jwt.verify(token, 'your-secret-key', (err, decoded) => {
    if (err) {
      return res.status(401).json({ message: 'Invalid token' });
    }
    req.user = decoded; // 将解码后的用户信息存储在req对象中
    next();
  });
});

// 处理请求的路由和逻辑
app.get('/api/endpoint', (req, res) => {
  // 获取用户信息
  const user = req.user;
  // 处理其他逻辑
  res.json({ message: 'Success' });
});

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