我是Firebase的新手，我可以在前台收到通知，但在后台什么都没收到。仅当“我的应用”再次进入前台时，通知才会显示。
我已经启用功能>后台模式>后台获取，从Xcode进行远程通知。
使用Advanced Rest Client发送请求并已将“优先级”设置为高，将“ content_available”设置为true
{
"to":"/topics/NFNKJABFLANKSL_ASKDWS",
"content_available":true,
"priority":"high",
"notification":{
"title":"234",
"body":"234",
"additionalData":"xxx",
"sound":"default",
"priority":"high",
"content_available":"true"
},
"data":{
"title":"123",
"body":"123",
"additionalData":"xxx",
"sound":"default",
"priority":"high",
"content_available":"true"
}
}
我已经按照Docs中的步骤进行操作，但是仍然无法解决此问题。
请帮助。
