ios - 使用 Swift 在 Firebase 中让用户保持最新状态

Question

我正在构建一个需要用户注册的应用，我使用 Firebase 作为我的后端。

我使用了日期选择器来允许用户选择他们的年龄，现在我想知道是否有办法在 Firebase 中自动更新年龄？手动操作似乎有点乏味。

任何帮助都会很棒。谢谢!

Firebase 不提供在后台运行代码的选项。

如果您仍希望在没有任何用户操作的情况下更新您的数据，您可以使用 Google Cloud Platform 等云服务及其 App Engine 从那里运行代码，根据当年更新所有用户年龄。

Google 在 just such an environment 上有一些方便的文档.

Firebase and Google App Engine standard environment

App Engine standard environment is an application platform that monitors, updates, and scales the hosting environment; all you need to do is write your mobile backend service code.

If your app needs to process user data or orchestrate events, extending Firebase with App Engine standard environment gives you the benefit of automatic real-time data synchronization

Recommended for:

• Firebase apps that need a backend service to modify the synchronized data.
• Backend services that run periodically to process or analyze Firebase data.

Not recommended for:

• Backend services that call native binaries, write to the file system, or make other system calls.
• Persistent connections to Firebase. App Engine standard environment reclaims socket connections after 2 minutes.
