我正在尝试构建一个包含聊天功能的应用程序，但出现错误消息:

[ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: [cloud_firestore/permission-denied] The caller does not have permission to execute the specified operation.

我的 Firebase 规则:

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
  
match /users/{uid}{
allow write: if request.auth != null && request.auth.uid == uid;
}

match /users/{uid}{
allow read: if request.auth != null;
}

match /chat/{document=**}{
    allow read: if request.auth != null;
    }
  }
}

enter image description here

如上图所示，当我写消息并发送时，它没有出现在屏幕上，错误信息写在终端

最佳答案

您可以按照以下规则制定规则。也是安全的

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