推荐答案
Firebase客户端SDK中没有API可以基于UID获取用户信息，因为这可能是安全问题.
There is no API in the Firebase client-side SDKs to get user information based on a UID, as this could potentially be a security concern.
如果您需要此信息，则可以实施使用Firebase Admin SDK(具有具有此功能)的自己的服务器，也可以将用户信息存储在辅助数据库中，例如Firebase自己的实时数据库或Cloud Firestore.然后，您可以从应用程序的其余部分查询该数据库，并使用数据库的服务器端安全规则来安全访问以满足您的需求.
If you need this information, you can either implement your own server that uses the Firebase Admin SDKs (which do have this functionality), or you can store user information in a secondary database, such as Firebase's own Realtime Database or Cloud Firestore. Then you can query this database from the rest of your application, and secure access to fit your needs with the database's server-side security rules.
