Cloud Firestore规则：

`

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if request.time < timestamp.date(2020, 8, 31);
    }
  }
}

`

Answer 1

原因：

解决方案：

在gradlew终端中使用“ gradlew signingReport”命令再次获取SHA-1。
向Firebase中添加新的SHA-1值，这可能会解决您的问题。
