应用程序被杀死/清除时未收到FCM推送通知 [英] FCM push notification not received when app is killed/swiped out

问题描述

我正在将通知从GCM迁移到FCM.在GCM中，当应用程序处于前景，背景或被杀死时，我能够收到通知，但是在FCM中，当应用程序未被刷出打开/杀死时，我无法接收通知.我有什么遗漏吗???

I am migrating notification to FCM from GCM. In GCM, I was able to receive notification when app was in foreground, background or killed, but in FCM, I am not able to receive notification when app is not opened/killed by swipe out. Am I missing anything????

我让您使用按摩标签巫婆r替换为身体标签.更改服务器中的有效负载.

i got you r using massage tag witch r replaced with body tag. change payload in server.

{         
"to" : "deviceToken",

"notification" : {
  "body" : "Pass body here",
  "title" : "Title For Notification",
  "icon" : " icon ",
  "sound" : "notification sound here"
}

}
