域名授权系统使用方法

// 客户端请求授权
const authUrl = 'https://authorization-server.com/auth';
const clientId = 'your-client-id';
const redirectUri = 'https://your-app.com/callback';
const scope = 'read write';

const url = `${authUrl}?response_type=code&client_id=${clientId}&redirect_uri=${encodeURIComponent(redirectUri)}&scope=${encodeURIComponent(scope)}`;
window.location.href = url;

// 处理授权回调
app.get('/callback', async (req, res) => {
  const { code } = req.query;
  const tokenResponse = await fetch('https://authorization-server.com/token', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded'
    },
    body: `grant_type=authorization_code&code=${code}&redirect_uri=${encodeURIComponent(redirectUri)}&client_id=${clientId}`
  });
  const tokenData = await tokenResponse.json();
  const accessToken = tokenData.access_token;
  // 使用访问令牌进行后续操作
});

const refreshToken = 'your-refresh-token';
const refreshResponse = await fetch('https://authorization-server.com/token', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded'
  },
  body: `grant_type=refresh_token&refresh_token=${refreshToken}&client_id=${clientId}`
});
const newTokenData = await refreshResponse.json();
const newAccessToken = newTokenData.access_token;
// 使用新的访问令牌进行后续操作
