使用fcm的Firebase Live分數推送通知

Question

我正在開發一款應用程序，一款允許用戶使用FCM主題訂閱訂閱其最喜愛的團隊的實時分數應用程序，我需要幫助才能將通知傳遞給該用戶。

現在我可以定期發送通知到設備，我可以通過控制檯，管理員node.js中，REST API手動發送通知，即使對於用戶訂閱訂閱話題，我還可以列出一個具體登記訂閱ID。

所以...我的用戶訂閱的主題是團隊id（橄欖球隊），我想要做的是通知用戶訂閱某個特定主題，當一些遊戲事件發生像目標，遊戲狀態（遊戲開始，半場時間，下半場比賽開始，比賽結束），這是推送通知系統的一個非常常見的用例。

我存儲在火力數據庫我的遊戲數據，我從外部供應商把它和「實時」更新，看起來像：

     "visitorteam_name": "FK Anzi Makhackala", 
     "visitorteam_score": "0", 
     "week": "5" 
    } 

的用戶訂閱球隊ID在JSON在團隊id上面是visitorteam_id，localteam_id，這些ID總是相同的，如果是訪問者或本地團隊，則該團隊無關緊要。在實例

我的訂閱ID API的樣子（我然後將其存儲在數據庫中，但不要緊，這個問題）：

{ 
    "application":"com.iid.example", 
    "authorizedEntity":"123456782354", 
    "platform":"Android", 
    "attestStatus":"ROOTED", 
    "appSigner":"1a2bc3d4e5", 
    "connectionType":"WIFI", 
    "connectDate":"2017-08-07 
    "rel":{ 
    "topics":{ 
     "42332":{"addDate":"2017-08-07"}, 
     "14810":{"addDate":"2017-08-07"}, 
     "14786":{"addDate":"2017-08-07"} 

    } 
    } 
} 

所以...我怎麼能通知訂閱設備一個特定的話題（團隊id）關於他們認購的團隊在玩遊戲的目標？

PS：我知道大概的解決方案是複雜的，但每一個幫助，實例會受到歡迎

嘗試使用火力地堡雲功能。 https://firebase.google.com/docs/functions/use-cases

您可以創建一個「訂閱」更改並自動觸發推送通知的Firebase雲端功能。
