如何从节点容器使用gmail api进行身份验证

const { google } = require('googleapis');
const credentials = require('path/to/credentials.json');

// 创建 OAuth2 客户端
const oauth2Client = new google.auth.OAuth2(
  credentials.client_id,
  credentials.client_secret,
  credentials.redirect_uris[0]
);

// 获取授权 URL
const authUrl = oauth2Client.generateAuthUrl({
  access_type: 'offline',
  scope: ['https://www.googleapis.com/auth/gmail.readonly']
});

// 在浏览器中打开授权 URL，用户授权后将获得授权码

// 使用授权码获取访问令牌
const getToken = async (code) => {
  const { tokens } = await oauth2Client.getToken(code);
  oauth2Client.setCredentials(tokens);
  return tokens;
};

// 使用访问令牌进行 API 调用
const listLabels = async () => {
  const gmail = google.gmail({ version: 'v1', auth: oauth2Client });
  const res = await gmail.users.labels.list({ userId: 'me' });
  console.log(res.data.labels);
};

// 运行身份验证流程
const runAuthFlow = async () => {
  console.log('请访问以下 URL 进行授权：', authUrl);
  const code = '在浏览器中获得的授权码';
  const tokens = await getToken(code);
  console.log('访问令牌：', tokens.access_token);
  await listLabels();
};

runAuthFlow().catch(console.error);
