const express = require('express');

const jwt = require('jsonwebtoken');

const app = express();

// 配置密钥

const secretKey = 'mySecretKey';

// 用户名和密码的映射

const users = {

alice: 'password1',

bob: 'password2'

};

// 验证用户名和密码

function authenticate(username, password) {

return users[username] === password;

}

// 生成JWT令牌

function generateToken(username) {

return jwt.sign({ username }, secretKey, { expiresIn: '1h' });

}

// 登录接口

app.post('/login', (req, res) => {

const { username, password } = req.body;

return res.status(401).json({ message: 'Invalid credentials' });

}

const token = generateToken(username);

// 受保护的资源接口

}
