iOS 10 FireBase when notification arrived, do not get call NotificationService.h Notification Service Extension

问题

I use firebase and get successfully Notifications but when notification arrived, do not get call NotificationService.h Notification Service Extension. I also set

NSExtensionPrincipalClass to NotificationService

NSExtensionPointIdentifier to com.apple.usernotifications.service

My notification is like

{   
"registration_ids": ["devicetoken"],    
"mutable_content": true,    
"data":{        
       "post_details": {
      "pcm_message": "asdf",
      "pcm_img_url": "http://portalvhds34w6bf5z9b21h.blob.core.windows.net/images/1519365008_5a8fab90cf683.jpg",
    }

   },    

"notification" : {
    "title" : "demo push",
    "body" : "this is push body"    } 

}

where is a problem or missing some information I have already set deployment target 10.0 in my whole project.
