Google cloud firestore Firestore问题，以身份验证模式恢复我的用户

我因身份验证问题被困了三天 当我试图恢复数据库中的用户时（代码1），会出现一条错误消息（代码2）。在我看来，我似乎在身份验证级别断开了连接。我还附加了我的请求代码（代码3）来读取数据库中的“用户”文件，因为在我看来，错误来自于此

代码1：

1
rules_version = '2';
2
service cloud.firestore {
3
  match /databases/{database}/documents {
4
    match /users /{userId=**} {
5
      allow create
6
      allow read : if request.auth != null 
7
    }
8
    match /cities/{city=**}{
9
        allow write : if true
10
        allow read : if true
11
      }
12
  }
13
}

代码2：

请帮帮我，我完全卡住了

你的规则有点乱，这是一个在模拟器中运行的清理版本

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /users/{userId=**} {
      allow create: if true;
      allow read: if request.auth != null;
    }
        
    match /cities/{city=**} {
      allow write: if true;
      allow read: if true;
    }
  }
}

我建议您更新上述规则，然后使用“规则操场”进行测试。这至少可以排除您的安全规则的问题。

我确实刚刚更改了此错误，但相同的问题仍然存在。我的回答是，您的规则存在一些小问题，并且上述问题在模拟器中进行了测试。
