如何只允许一个管理员用户编写Firebase数据库？ [英] How to only allow one admin user to write Firebase Database?

问题描述

我试图建立一个只有我能写的Firebase数据库。所以没有用户将有权写任何东西。但是每个人都可以阅读。

但是，我无法为此设置规则。我有一个管理员用户，我使用电子邮件/密码登录创建，我知道它的UID。假设我的UID是： dJrGShfgfd2

我试过这两种方法，但是他们不允许我写

 {
rules：{
events：{
 .read：true，
.write：auth.uid ==='dJrGShfgfd2'
} 
} 
} 
  
 
 $ b 
。
 
 
  {
规则：{
users：{
$ user_id：{
.read：true，
.write：$ user_id == ='dJrGShfgfd2'
} 
} 
} 
} 
  
 
 $ b $那么如何才能让一个具有特定UID的用户向数据库写入任何内容呢？     ：
 
 
  {
rules：{
.read：true，
 .write：auth.uid ==='dJrGShfgfd2'
} 
} 
  
世界上的每个人都可以读取数据，但只能读取用户与UID  dJrGShfgfd2 （和进程管理访问权限）可以写入数据。
 
I am trying to set up a Firebase database that only I can write. So no user will have permission to write anything. But everyone will be able to read it.

However, I could not set up the rules for it. I have one admin user that I created using Email/Password login, and I know its UID. Let's say my UID is: dJrGShfgfd2

I tried these two methods, but they didn't allow me to write to database.
{
  "rules": {
    "events": {
      ".read": true,
      ".write": "auth.uid === 'dJrGShfgfd2'"
    }
  }
}
.
{
  "rules": {
    "users": {
      "$user_id": {
        ".read" : true,
        ".write": "$user_id === 'dJrGShfgfd2'"
      }
    }
  }
}
So how do I allow only one user with a specific UID to write anything to database?
解决方案
This should work:
{
  "rules": {
    ".read": true,
    ".write": "auth.uid === 'dJrGShfgfd2'"
  }
}
Everyone in the world will be able to read the data, but only the user with UID dJrGShfgfd2 (and processes with administrative access) can write the data.
