颤振/修复:读写权限有问题

Question

我试图使它，使我的应用程序只显示用户的任务，只有该用户已经创建。我有一个帐户创建系统，我不希望其他帐户能够查看和编辑任务，已创建的其他人。我已经设置了规则并更改了我的流，但是在创建任务和查看任务时，它给了我一个拒绝权限的错误。我在这里做错什么了吗？

这就是我要犯的错误..。

name);limitType=LIMIT_TO_FIRST) W/

( 7671)：(24.2.1) Firestore:侦听查询(target=Query(target=Query/myemail@gmail.com，由target=Query发出的订单失败)：状态{code=PERMISSION_DENIED，description=Missing或权限不足，cause=null}

这是我的任务代码..。请注意我的_TasksState类的顶部，其中声明了权限

  const Tasks({Key? key}) : super(key: key);

这些是我宣布的规则..。如果你想要消防控制台的截图，请告诉我。

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /tasks/{taskId} {
      allow read, write: if request.auth.uid == resource.data.userId;
    }
  }
}

Answer 1

试试这个许可..。

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