一键登录

// 使用OAuth 2.0进行一键登录的简单示例
function loginWithOAuth(provider) {
    const authUrl = `https://example.com/oauth/authorize?response_type=code&client_id=${CLIENT_ID}&redirect_uri=${REDIRECT_URI}&scope=email&provider=${provider}`;
    window.location.href = authUrl;
}

// 用户点击登录按钮时调用此函数
document.getElementById('loginButton').addEventListener('click', () => {
    loginWithOAuth('wechat');
});

const express = require('express');
const axios = require('axios');
const app = express();

app.get('/callback', async (req, res) => {
    const { code } = req.query;
    try {
        const response = await axios.post('https://example.com/oauth/token', {
            code,
            client_id: CLIENT_ID,
            client_secret: CLIENT_SECRET,
            redirect_uri: REDIRECT_URI,
            grant_type: 'authorization_code'
        });
        const { access_token } = response.data;
        // 使用access_token获取用户信息
        res.send('登录成功');
    } catch (error) {
        res.status(500).send('登录失败');
    }
});

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