如何确保用户只能在Firebase中查看和访问他们自己的数据？ [英] How to make sure a user can only see and access their own data in firebase?

问题描述

我是firebase的新手。在我的Android应用程序中，我希望每个用户只能访问他创建的数据。我正在阅读 https://www.firebase.com/docs/security/ guide / secured-data.html ，但没有多少意义。假设我已经使用电子邮件和密码登录，那么我应该如何编写Firebase规则？

谢谢！

火力地堡规则

  {
 的规则：{
的.read ：真，
 的.WRITE：真
} 
} 
  

Java代码的

  myFirebaseRef.child（ 消息）的setValue（ 这是消息）。 
  

解决方案

由于乔伊Roosing，我能够找出其余的。我需要根据用户的uid对数据进行分组。

首先，修改Firstbase规则，如Joey所说：

  {
 的规则：{
 的用户：{
 $ UID：{
.write：$ uid === auth.uid，
.read：$ uid === auth.uid
} 
} 
 
 
 
 
 
 $ b 
 然后，在我的Java代码中： 
  Firebase rootRef =新的Firebase（https://user-account.firebaseio.com/）; 
 //假设用户已经登录。
 Firebase userRef = rootRef.child（users /+ rootRef.getAuth（）。getUid（））; 
 userRef.child（message1）。setValue（Hello World）; 
  
 
 
 
 最后，我的数据会是这个样子： 
 
 
 
    
 
I am new to firebase. In my Android app, I want each user to only access the data he created. I was reading https://www.firebase.com/docs/security/guide/securing-data.html, but didn't make much sense out of it. Assuming I am already logged in with an email and password,

How can should I write the Firebase Rules?
How do write to my Firebase data in my Android Java code?
Thanks!

Firebase Rules
{
    "rules": {
        ".read": true,
        ".write": true
    }
}
Java Code
myFirebaseRef.child("message").setValue("This is the message");

解决方案
Thanks to Joey Roosing, I was able to figure out the rest of it. I need to group the data based on the uid of the user.

First, modify the Firstbase rules as Joey mentioned:
{
  "rules": {
    "users": {
      "$uid": {
        ".write": "$uid === auth.uid",
        ".read": "$uid === auth.uid"
      }
    }
  }
}
Then, in my Java Code:
Firebase rootRef = new Firebase("https://user-account.firebaseio.com/");
// Assuming the user is already logged in.
Firebase userRef = rootRef.child("users/" + rootRef.getAuth().getUid());
userRef.child("message1").setValue("Hello World");
In the end, my data would look something like this:
