无法从iOS SDK中获取所有Firebase身份验证用户的列表，因为那样会导致各种滥用.
There is no way to get a list of all Firebase Authentication users from the iOS SDK, as that would allow all kinds of abuse.
不过，有两种实现用例的常用方法:
There are two common approaches to implementing your use-case though:
- 将每个用户所需的信息存储在Firebase的实时数据库或Cloud Firestore等云数据库中.您需要在注册每个用户时执行此操作，然后您的应用程序才能从那里读取它.
- 使用Admin SDK进行Firebase身份验证，确实可以列出用户.此SDK仅可在受信任的环境中使用，例如开发机器，您控制的服务器或Cloud Functions.您将使用Admin SDK创建一个自定义API，您的应用程序可以调用它，然后返回用例所需的信息.
- Store the information you need for each user in a cloud database, such as Firebase's Realtime Database or Cloud Firestore. You'd do this on registering each user, and then your app can read it from there.
- Use the Admin SDK for Firebase Authentication, which does have a way to list users. This SDK can only be used in trusted environments, such as your development machine, a server you control, or Cloud Functions. You'd use the Admin SDK to create a custom API that your application can call, and that then return the information needed for your use-case.
这两种方法都使您可以完全控制要公开的数据，因此，不必担心客户端API会固有的风险.不过，请务必仅允许使用针对您的应用程序授权的方式访问数据，否则很容易泄漏用户数据.
Both of these give you full control of what data is exposed, so don't have the inherent risk that a client-side API would have. Be sure to only allow access to the data in a way that is authorized for your application though, as it's quite easy to leak user data otherwise.
