使用fcm的Firebase Live分数推送通知

Question

我正在开发一款应用程序，一款允许用户使用FCM主题订阅订阅其最喜爱的团队的实时分数应用程序，我需要帮助才能将通知传递给该用户。

现在我可以定期发送通知到设备，我可以通过控制台，管理员node.js中，REST API手动发送通知，即使对于用户订阅订阅话题，我还可以列出一个具体登记订阅ID。

所以...我的用户订阅的主题是团队id（橄榄球队），我想要做的是通知用户订阅某个特定主题，当一些游戏事件发生像目标，游戏状态（游戏开始，半场时间，下半场比赛开始，比赛结束），这是推送通知系统的一个非常常见的用例。

我存储在火力数据库我的游戏数据，我从外部供应商把它和“实时”更新，看起来像：

     "visitorteam_score": "0", 
     "week": "5" 
    } 

的用户订阅球队ID在JSON在团队id上面是visitorteam_id，localteam_id，这些ID总是相同的，如果是访问者或本地团队，则该团队无关紧要。在实例

我的订阅ID API的样子（我然后将其存储在数据库中，但不要紧，这个问题）：

{ 
    "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...我怎么能通知订阅设备一个特定的话题（团队id）关于他们认购的团队在玩游戏的目标？

PS：我知道大概的解决方案是复杂的，但每一个帮助，实例会受到欢迎

尝试使用火力地堡云功能。 https://firebase.google.com/docs/functions/use-cases

您可以创建一个“订阅”更改并自动触发推送通知的Firebase云端功能。
