Firebase 规则 - 如果用户的 uid 等于文档的字段值 userId 则允许读取
我试图仅在用户的 uid 与 userId 匹配（用红色圈出）时才允许读取硬币的文档。
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if false;
}
match /coins/{coinId} {
allow read: if request.auth != null && resource.data.userId == request.auth.uid;
allow write: if request.auth != null;
}
}
}
当我登录我的帐户时，此规则在控制台中返回错误。并且没有数据显示。 快照侦听器中未捕获的错误：FirebaseError：缺少权限或权限不足。
根据我在此处阅读的所有内容，以下代码似乎应该有效，但事实并非如此。
I am trying to only allow reads coins's documents if the user's uid matches the userId (encircled in red).
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if false;
}
match /coins/{coinId} {
allow read: if request.auth != null && resource.data.userId == request.auth.uid;
allow write: if request.auth != null;
}
}
}
This rule returns an error in the console when I log into my account. And no data is displayed.Uncaught error in snapshot listener: FirebaseError: Missing or insufficient permissions.
Based on everything I've read here it seems like the following code should work, but it doesn't.

有同样的问题。
改变：
资源.data.userId == request.auth.uid;
到：
request.resource.data.userId == request.auth.uid;
Had the same problem.
Changed:
resource.data.userId == request.auth.uid;
To:
request.resource.data.userId == request.auth.uid;
