为什么云Firestore不允许使用Firebase Auth验证访问？

Question

我有一个具有以下安全规则的云Firestore数据库：

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

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

Answer 1

根据文档的这一部分

service cloud.firestore {
  match /databases/{database}/documents {
    // Make sure the uid of the requesting user matches name of the user
    // document. The wildcard expression {userId} makes the userId variable
    // available in rules.
    match /users/{userId} {
      allow read, update, delete: if request.auth != null && request.auth.uid == userId;
      allow create: if request.auth != null;
    }
  }
}

应该是{userID}而不是{userID=**}才能访问变量
