【问题描述】：

我已经实现了 FCM 通知来发送通知。 当我从 firebase 控制台发送通知时，我会收到通知。但是当我从服务器发送通知时，我得到了成功但通知没有出现..

其次，如何获取通知响应数据？

我的didReceiveRemoteNotification 功能也不起作用。这是我的代码：

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) 

 print("Recived: \(userInfo)")
    print("success")


func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                 fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) 

    print("Recived: \(userInfo)")
    print("success")


func application(application: UIApplication,  didReceiveRemoteNotification userInfo: [NSObject : AnyObject],  fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) 

    print("Recived: \(userInfo)")
    print("success")


func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) 

    self.application(application, didReceiveRemoteNotification: userInfo)  (UIBackgroundFetchResult) in

       print("Recived: \(userInfo)")
    print("success")
    

   print("Recived: \(userInfo)")
    print("success")

    let state: UIApplicationState = application.applicationState
    // user tapped notification while app was in background
    if state == .inactive || state == .background 
        print("Inactive")
    
    else 
        print("Active")
    

【问题讨论】：

如何从服务器发送通知负载？你能把那个payload贴在这里吗...

当您从服务器发送通知时，您使用的是 FCM 令牌还是设备令牌？

我在从服务器发送通知时使用 FCM 令牌

我正在使用这个通知负载。 "aps" : "alert" : "带有自定义负载的通知！", "badge" : 1, "content-available" : 1 , "data" : "title" : "Game Request", "body" : "Bob 想玩扑克", "action-loc-key" : "PLAY"

我在使用 Firebase Admin Java SDK 时遇到了这个问题，通知到达 android 设备。但不适用于 ios 设备。并且使用 Firebase 控制台也可以，使用 Legacy Api 也可以。

【参考方案1】：

我发现下面的消息最适合我在 Android 和 iOS 上使用（我使用 firebase 函数来发送它，但这不重要）。请注意，要使其正常工作，您需要使用 send 方法而不是已弃用的方法之一，例如：admin.messaging().send(message)

要发送给send的消息：

const message = 
    token: addresseePushToken,
    /*
       Apple Push Notification Service
       https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/sending_notification_requests_to_apns
    */
    apns: 
      headers: 
        'apns-priority': 10,        // defaults to 10 (send immediately), can be set to 5 (consider device power)
        'apns-collapse-id': chatId  // group multiple notifications into a single notification (must not exceed 64 bytes)
      ,
      payload: 
        aps: 
          alert: 
            title: title,
            body: doc.message,
          ,
          badge: unseenCount+1,
        
      
    ,
    /*
       Android specifics
       https://firebase.google.com/docs/cloud-messaging/admin/send-messages#android_specific_fields
    */
    android: 
      priority: 'high',               // either 'normal' or 'high' - high send immediately & waking sleeping device
      notification:                  // notification object creates status bar notification if app in background
        tag: chatId,                  // key for grouping notifications (Android only)
        title: title,
        body: doc.message,
        color: '#ffffff',             // notification's icon color
        icon: thumbUrl,               // if not specified FCM displays the launcher icon as defined in app manifest
      
    ,
    // data object is available to the app both when received in foreground and background
    data: 
      type: 'chat',
      senderId: senderId,
      title: title,
      body: doc.message,
    ,
  

【参考方案2】：

我解决了一个与此非常相似的问题，将其添加到 Firebase 通知中：

"apns" : 
  "payload" : 
    "aps" : 
        "content-available" : 1
