Xamarin android-如何检测传递FCM前台消息的传递事件

Question

我已经在Xamarin android应用程序中实现了FCM通知。当前台通知传递它时，不会调用OnMessageReceived事件。如何获取前台消息传递事件。

使用邮递员发送 FCM 消息的代码

{ 
 "to":"eXj6c43Jueu6pZ7J6nlPJk81plm5UGjNAwzEGDMM2WQa3EBSxJ-85GDn09wqJ6mE4Jq5nkJ1Qdo", 
 "notification" : {
 "body" : "New homework assigned",
 "OrganizationId":"619",
 "click_action":"SISActivity",
 "content_available" : true,
 "priority" : "high",
 "title" : "KG school",
 "bodyText" : "great match!"
 },
 "data" : {
 "OrganizationId":"6166",
 "moduleName":"Homework",
 "bodyText" : "New homework assigned",
}
}

Answer 1

在这里我回答我的问题。问题是，在发送通知时，我notification有效负载以及data，如果前台的应用程序在这种情况下OnMessageReceived不会调用。如果您需要调用OnMessageReceived始终不发送notification有效负载，则只需要发送data消息。谢谢
