Permissions problems with Flutter and FireBase FireStore
问题
抱歉，以下是翻译好的内容：
我是一个完全的 FireStore 和 FireBase 初学者。我试图做一些简单的事情，但 FireBase 告诉我我没有权限这样做。我正在使用 Flutter。在 FireBase 规则控制台中，我设置了以下规则。我只有一个项目和一个 Firestore 数据库。
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow write: if request.auth != null;
allow read: if true;
}
}
}
我已经设置了一个用户集合，其中 uid 作为集合参数，并在匿名登录到 Flutter 后运行以下代码，不会引发错误。UserID 已设置为有效值。
void createUser(String userID, String userName, String password) async {
final CollectionReference _users =
FirebaseFirestore.instance.collection("Users");
final data = {"Created": DateTime.now(), "LastLoggedIn": DateTime.now()};
_users.doc(userID).set(data, SetOptions(merge: true));
}
我收到以下错误消息：
10.3.0 - [FirebaseFirestore][I-FST000001] 在 Users/QUIEvBpJeAgprgEan0S736aKjdk2 处写入失败：缺少或不足的权限。
我正在使用匿名登录。
即使我使用下面的规则，它被认为允许读写数据，我仍然收到相同的错误消息：
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if true;
}
}
}
我等待了几分钟以确保权限已设置并进行了测试。

I am a complete beginner to FireStore and FireBase. I am trying to do something simple and FireBase is saying I do not have permission to do it. I am using Flutter. I have the following rules set up in FireBase rules console. I only have one project and one Firestore database.
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow write: if request.auth != null;
allow read: if true;
}
}
}
I have a collection of users setup which has a uid as the collection parameter and running the following code after signing into Flutter anonymously which does not throw an error. UserID is set to a valid value.
void createUser(String userID, String userName, String password) async {
final CollectionReference _users =
FirebaseFirestore.instance.collection("Users");
final data = {"Created": DateTime.now(), "LastLoggedIn": DateTime.now()};
_users.doc(userID).set(data, SetOptions(merge: true));
}
I am getting the following error message:
> 10.3.0 - [FirebaseFirestore][I-FST000001] Write at Users/QUIEvBpJeAgprgEan0S736aKjdk2 failed: Missing or insufficient permissions.
I am using anonymous log-ons.
Even when I use the following rules which is supposed to allow all reading and writing of the data I get the same error:
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if true;
}
}
}
I allowed several minutes to go by between setting the permissions and testing.

你尝试过使用时间戳的默认规则吗：
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if
request.time < timestamp.date(2023, 11, 25);
}
}
}
英文:
Have you tried the default rule with timestamp :
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if
request.time < timestamp.date(2023, 11, 25);
}
}
}
