转到firebase中的规则，编辑规则.....(提供时间戳或设置为false) 我的解决方案。

service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if request.time < timestamp.date(2021, 8, 18);
    }
  }
}

也许你该把日期去掉

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if
          request.time < timestamp.date(2021, 12, 12);
    }
  }
}

如果有人登陆这里试图使用服务帐户访问Firestore:

我通过在GCP的IAM设置中授予Service - Account Cloud Datastore User角色之外的Service Account User角色解决了这个问题。

进入数据库-> 规则- - - >

发展:

更改允许读，写:如果为false;真正的;

注意:它只是用于开发目的的快速解决方案，因为它将关闭所有安全性。因此，不建议在生产中使用。

生产:

如果从firebase验证:更改允许读，写:如果为false;请求。Auth != null;

NPM I—save firebase @angular/fire

在app.module中确保你导入了

import { AngularFireModule } from '@angular/fire';
import { AngularFirestoreModule } from '@angular/fire/firestore';

进口

AngularFireModule.initializeApp(environment.firebase),
    AngularFirestoreModule,
    AngularFireAuthModule,

在实时数据库规则中，确保你有

{
  /* Visit  rules. */
  "rules": {
    ".read": true,
    ".write": true
  }
}

在云壁炉规则确保你有

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if true;
    }
  }
}

时间限制可能已过

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {

    // This rule allows anyone on the internet to view, edit, and delete
    // all data in your Firestore database. It is useful for getting
    // started, but it is configured to expire after 30 days because it
    // leaves your app open to attackers. At that time, all client
    // requests to your Firestore database will be denied.
    //
    // Make sure to write security rules for your app before that time, or else
    // your app will lose access to your Firestore database
    match /{document=**} {
      allow read, write: if request.time < timestamp.date(2020,7, 1);
    }
  }
}

这一行更改了日期:

 allow read, write: if request.time < timestamp.date(2020,7, 1);
