阅读更多关于 How to send firebase notifications to audience via HTTP

问题 In Firebase Console I set up audiences based on various user properties and now am able to send notifications to different user segments via console.

You must implement your own App Server and implement the scheduled push yourself (also mentioned it here ). 来源： https://stackoverflow.com
