Question

我有一组数据，例如products和两组不同的用户merchants和users。如何授予products上的商人的读写访问权限，而仅授予users的只读访问权限？

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

以上规则仅定义了单个用户的访问权限。

起点：

        string[] rHistoryUserIds = Info
                           .Where(u => !Equals(u.Rhistory, null))
                           .SelectMany(v => v.Rhistory)
                           .Select(c => new string[] { c.User.UserId })
                           .SelectMany(m => m)
                           .Distinct().Where(x => !string.IsNullOrEmpty(x)).ToArray();

        string[] vHistoryUserIds = Info
                           .Where(u => !Equals(u.Vhistory, null))
                           .SelectMany(v => v.Vhistory)
                           .Select(c => new string[] { c.User.UserId })
                           .SelectMany(m => m)
                           .Distinct().Where(x => !string.IsNullOrEmpty(x)).ToArray();

        string[] userIds = rHistoryUserIds.Union(vHistoryUserIds).ToArray();

假设用户的字段match /users/{userId} { allow read: if request.auth.uid == userId; } match /products/{productid} { // Anyone authenticated can read allow read: if request.auth.uid != null; // Only merchants can write allow write: if get(/databases/$(database)/documents/users/$(request.auth.uid)).data.type == 'merchant' }带有可能的值type
