I need to run a Firebase function whenever my user updates their email address, except auth only has onCreate and onDelete. How can I react to email updates?

推荐答案

目前无法直接响应在 Firebase 身份验证中更改的电子邮件地址.如果您希望将其视为一项功能，请提交功能请求.

It's not possible today to directly react to an email address changing in Firebase Authentication. If you'd like to see that as a feature, please file a feature request.

您可以通过让您的应用监听身份验证事件(Android)，取 用户对象 传递给您的听众，并将用户的电子邮件地址写入该用户 UID 的 RealtimeDatabase 位置(或 Firestore 文档).然后，您可以有一个数据库触发器来跟踪您的用户在数据库，并对那里的变化做出反应.

You can react to it indirectly by having your app listen to authentication events (Android), take the User object delivered to your listener, and write the user's email address to a RealtimeDatabase location (or Firestore document) for that user's UID. Then, you can have a database trigger that tracks the location of your users in the database, and react to the change there.
