如何从Firebase的实时数据库中删除具有UID的用户? [英] How to delete a user with UID from Real Time Database in Firebase?

问题描述

数据库结构如下

-LGw89Lx5CA9mOe1fSRQ {
    uid: "FzobH6xDhHhtjbfqxlHR5nTobL62"
    image: "https://pbs.twimg.com/profile_images/8950378298..."
    location: "Lorem ipsum, lorem ipsum"
    name: "Lorem ipsum"
    provider: "twitter.com"
}

如何以编程方式删除所有内容，包括-LGw89Lx5CA9mOe1fSRQ键?

How can I delete everything, including the -LGw89Lx5CA9mOe1fSRQ key programmatically?

我已经看过了，但是它已经过时了，

I looked at this, but it's outdated and deprecated Firebase: removeUser() but need to remove data stored under that uid

我还查看了此，但是这要求用户不断登录(我将用户ID保存在localStorage中)，并且如果我编写firebase.auth().currentUser，则刷新后将返回null.数据记录和用户帐户是通过社交网络提供商创建的，我可以在Firebase控制台的 Authentication 和 Database 标签上看到数据.

I've also looked at this, but this requires for user to constantly sign in (I'm saving the user ID in localStorage) and it returns null on refresh if I write firebase.auth().currentUser. Data records and user accounts are created through social network providers and I can see the data both on Authentication and Database tab in the Firebase console.

我已经尝试过使用这些代码，但是它什么也没做.

I've tried with these piece of code but it does nothing.

 // currentUser has a value of UID from Firebase
 // The value is stored in localStorage
 databaseChild.child(currentUser).remove()
   .then(res => {
       // res returns 'undefined'
       console.log('Deleted', res);
   })
   .catch(err => console.error(err));

最重要的是，我需要一键式同时从 Authentication 标签和 Database 中删除具有特定UID的用户.

The bottom line is, I need to delete the user (with a specific UID) from the Authentication tab and from the Database at the same time with one click.

我知道有一个 Firebase管理SDK 但是我正在创建单页应用程序，并且没有任何后端代码.一切都在前端完成.

I know that there is a Firebase Admin SDK but I'm creating a Single Page Application and I don't have any back end code. Everything is being done on the front end.

感谢您提供任何帮助.

推荐答案

要删除客户端上的用户登录帐户的链接，已经找到的链接是您要在客户端上执行的操作的唯一选择.通常出于安全原因，您希望将大多数操作保留在服务器上，例如用于帐户创建/删除之类的操作，而Firebase会强制执行此操作.仅当您最近登录时才能删除帐户，客户端无法开始删除旧的/随机的帐户.

The link you already found for deleting the user-login-account client-side is your only option if you want to keep the action on the client. Usually you want to keep most of the actions for things like account creation/deletion on the server for security reasons, and Firebase forces the issue. You can only delete your account if you were recently logged in, you can't have client-side start deleting old/random accounts.

更好的选择是创建自己的Cloud Function，以处理与删除用户有关的所有事情.您必须使用已经找到的管理SDK 为此...但是您可以让Cloud Function执行任意数量的操作-它必须从身份验证"标签中删除用户，并删除数据库中的匹配数据.

The better option is to create your own Cloud Function to handle everything related to deleting a user. You would have to use the Admin SDK that you already found for this... but you could have that Cloud Function perform as many actions as you want - it will have to delete the user from the Auth tab, and delete the matching data in the Database.
