Firebase的Cloud Functions-获取当前用户ID [英] Cloud Functions for Firebase - Get current user id

问题描述

花了一些时间寻找似乎是一个简单问题的解决方案，但是...如何在云函数内部获取当前用户的详细信息(不使用functions.auth触发器时)?我敢肯定对此必须有一个简单的解决方案. (我希望)

Spent a while searching out a solution to what seems a simple problem but... How can I get the current users details inside a cloud function (when not using an functions.auth trigger)? I'm sure there must be a simple solution to this. (I hope)

感谢您的回复...刚刚完成了，但是如何在存储触发的事件中从Firebase数据库中获取/user/uid?例如

Thanks for the replies... Just done that but how would I get the /user/uid from the Firebase DB within a storage triggered event? e.g.

exports.addUploadInfoToDatabase = functions.storage.object().onChange(event => {
  console.log("firebase storage has been changed");
  // need to find the uid in here somehow
  admin.database().ref(`/user/uid`).push({testKey:"testData"});
})

如果我错过了您的答复，请致谢.

Applogies if I've missed the point in your replies.

谢谢...

推荐答案

首先，您可以通过在用户上调用getIdToken()来获取当前登录的用户tokenId:

First you can get the current signed-in user tokenId by calling getIdToken() on the User: https://firebase.google.com/docs/reference/js/firebase.User#getIdToken

firebase.auth().currentUser.getIdToken(true)
.then(function (token) {
    // You got the user token
})
.catch(function (err) {
    console.error(err);
});

然后将其发送到您的云功能.

Then send it to your cloud function.

然后在您的云功能中可以使用: https://firebase .google.com/docs/auth/admin/verify-id-tokens

Then in your cloud function you can use: https://firebase.google.com/docs/auth/admin/verify-id-tokens

示例:

admin.auth().verifyIdToken(idToken)
  .then(function(decodedToken) {
    var uid = decodedToken.uid;
    // ...
  }).catch(function(error) {
    // Handle error
  });

decodedToken的文档位于此处: https://firebase.google.com/docs/reference/admin/node/admin.auth.DecodedIdToken#uid

The documentation for decodedToken is here: https://firebase.google.com/docs/reference/admin/node/admin.auth.DecodedIdToken#uid

DecodedIdToken包含用户uid，然后您可以通过调用以下命令来获取用户: https://firebase.google.com/docs/reference/admin/node/admin.auth.Auth#getUser

DecodedIdToken contains the user uid, then you can get the user by calling this: https://firebase.google.com/docs/reference/admin/node/admin.auth.Auth#getUser

哪个返回UserRecord https://firebase.google. com/docs/reference/admin/node/admin.auth.UserRecord

Which returns a UserRecord https://firebase.google.com/docs/reference/admin/node/admin.auth.UserRecord
