将state参数设置为Stripe查询以传递FireStore uuid

Question

我正在尝试将FirebaseFirestore用户Uid传递给Stripe/firestore云函数。

所以我会有一个如下的https查询：

https://connect.stripe.com/express/oauth/authorize?response_type=code

这是我的功能

exports.connectStripeExpressAccount = functions.https.onRequest((req, res) =>{
  console.log('query state is  ----> ' + req.query.state);
  const authCode = req.query.code;
  return stripe.oauth.token({
    grant_type: 'authorization_code',
    code: authCode,
  }).then(async response => {
      var connected_account_id = response.stripe_user_id;
      const uid = req.query.state
      const writeResult = await admin.firestore().collection('Registration').doc(uid)
                           .set({'customer_id': connected_account_id});
      return res.send("Well done, account integration is completed. You can now close the window and go back to the app");
      });
});

Answer 1

如果用户uid存储在查询参数state中，并且URL如下所示：https://connect.stripe.com/express/oauth/authorize?response_type=code

您的代码如下所示：

js prettyprint-override">exports.connectStripeExpressAccount = functions.https.onRequest((req, res) =>{
  console.log('query state is  ----> ' + req.query.state);
  const authCode = req.query.code;
  return stripe.oauth.token({
    grant_type: 'authorization_code',
    code: authCode,
  }).then(async response => {
      var connected_account_id = response.stripe_user_id;
      const uid = req.query.state
      const writeResult = await admin.firestore().collection('Registration').doc(uid)
                           .set({'customer_id': connected_account_id});
      return res.send("Well done, account integration is completed. You can now close the window and go back to the app");
      });
});

Answer 2

对于与Express Accounts的新集成，理想情况下应该使用Account Links功能，而不是OAuth。这就是说，如果你提供了状态值，它应该能够执行，所以我会确保你在打开WebView时确实提供了它。
