由 userNotificationCenter 而非 Firebase 函数处理的 Firebase 通知答案

【问题标题】：Firebase Notification being handled by userNotificationCenter not Firebase functions由 userNotificationCenter 而非 Firebase 函数处理的 Firebase 通知

【问题描述】：

我的应用程序正在实现 Firebase Cloud 消息传递以发送通知。每当我使用 Firebase 控制台测试 Firebase 通知时，都会出现由 userNotificationCenter 函数处理的通知，并且会显示 didReceiveRemoteNotification 而不是 Firebase applicationReceivedRemoteMessage 函数，我是否遗漏了什么？此外，当我尝试打印刚刚来自 Firebase 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)
}

【解决方案1】：

我能够继续挖掘并找到我正在寻找的答案。对于任何为此苦苦挣扎并了解 Firebase 通知如何与 IOS 配合使用的人。上面的设置代码是正确的。我遇到的主要问题是通知没有通过 Firebase 函数 applicationReceivedRemoteMessage 得到解决。根据我的理解，这是不正确的！ Firebase 控制台仅允许您将消息作为通知发送！这意味着您的应用将通过 apns 获得通知！如果要触发 applicationReceivedRemoteMessage 函数，则需要将消息作为数据 json 对象发送。您可以通过邮递员在这里查看更多信息：Unable to send data message using firebase console。希望这会有所帮助！
