推荐答案
对于对实时数据库的GET/读取请求，安全规则中提供了以下信息:
For a GET/read request to the Realtime Database, the following information is available in your security rules:
- 请求的路径，或
查询. -
auth变量指示登录的用户，包括auth.token.
因此，如果您想传递信息，则必须将其放入其中之一.例如，您可以将有效负载作为路径的一部分，也可以将其作为自定义声明.
So if you want to pass information, you will have to put it into one of these. For example, you can make the payload part of the path, or you can store it in the user's profile as a custom claim.
通常，对于临时信息(例如随机数或共享机密)，首选放置路径，而对于某些半永久状态的用户(例如将其标记为应用程序管理员)，自定义声明更为常见
Putting in the path is typically preferred for short-lived information, like a nonce or a shared secret, while a custom claim is more common for some semi-permanent state of the users, such as them being marked as an application administrator.
