Question

我的应用程序正在实施Firebase Cloud消息传递来发送通知。每当我使用Firebase控制台测试Firebase通知时，将通过将显示userNotificationCenter函数和didReceiveRemoteNotification处理通知，而不是由Firebase applicationReceivedRemoteMessage函数处理通知，我是否缺少某些东西？另外，当我尝试打印刚从Firebase发出的通知时，userNotification函数没有任何数据。这是我的设置：

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, FIRMessagingDelegate {

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        UNUserNotificationCenter.current().delegate = self
        FIRMessaging.messaging().remoteMessageDelegate = self
        FIRApp.configure()
        registerForFireBaseNotifications()
    //Other set up variables
    connectToFcm()

        return true
    }

func registerForFireBaseNotifications(){
        let authOptions: UNAuthorizationOptions = [.alert, .sound, .badge]
        UNUserNotificationCenter.current().requestAuthorization(options: authOptions, completionHandler: {_, _ in })
        application.registerForRemoteNotifications()
    }

    func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
        print("Recieved remote firebase notification: %@", remoteMessage.appData)
    }

    func tokenRefreshNotification(notification: NSNotification) {
        let refreshedToken = FIRInstanceID.instanceID().token()
        print("FCM: Connected to FCM. Token : \(String(describing: refreshedToken))")
        connectToFcm()
    }

    func connectToFcm() {
        // Won't connect since there is no token
        guard FIRInstanceID.instanceID().token() != nil else {
            print("FCM: Token does not exist.")
            return
        }

        // Disconnect previous FCM connection if it exists.
        FIRMessaging.messaging().disconnect()

        FIRMessaging.messaging().connect { (error) in
            if error != nil {
                print("FCM: Unable to connect with FCM. \(error.debugDescription)")
            } else {
                print("Connected to FCM.")
            }
        }
    }

//Non firebase notifications
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (_ options: UNNotificationPresentationOptions) -> Void) {
    //do something with notifications that came while on foreground
}

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    //do something with notifications that came from background
}

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.sandbox)
}

我能够不断挖掘并找到所需的答案。对于任何为此感到困惑并了解Firebase通知如何与IOS一起工作的人。上面的设置代码正确无误。我遇到的主要问题是通知没有通过Firebase函数applicationReceivedRemoteMessage处理。根据我的理解，这是不正确的！ Firebase控制台允许您仅将消息作为通知发送！这意味着您的应用将通过apns收到通知！如果要触发applicationReceivedRemoteMessage函数，则需要将消息作为数据json对象发送。您可以通过邮递员执行以下操作：Unable to send data message using firebase console。希望这会有所帮助！

由userNotificationCenter处理的Firebase通知不是Firebase功能
