没有收到来自 Firebase 控制台的推送通知

【中文标题】没有收到来自 Firebase 控制台的推送通知

【英文标题】：not geting push notification from firebase console

【发布时间】：2019-09-17 08:03:57

【问题描述】：

我已经实现了有关实现推送通知的所有步骤，但是当我测试通知时，控制台它不会出现在 iPhone 上，但是当我使用来自“https://pushtry.com/”的密码 n 令牌的生产 apns 证书 n 进行测试时，它工作正常。我无法纠正为什么会这样。我还启用了功能部分的推送通知。谢谢 下面是我的应用委托代码

mport Firebase
import FirebaseMessaging
import FirebaseInstanceID
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder,UIApplicationDelegate,MessagingDelegate,UNUserNotificationCenterDelegate

    var window: UIWindow?
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool 

        // Override point for customization after application launch.
        GMSServices.provideAPIKey("AIzaSyB5HWsalLBmBFjLC3NjTUF2KB7i5zvz45k")
        GMSPlacesClient.provideAPIKey("AIzaSyB5HWsalLBmBFjLC3NjTUF2KB7i5zvz45k")


      let notificationCenter = UNUserNotificationCenter.current()

        // It is For Notification Allow Authentications
        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge])  (isGranted, err) in
            guard isGranted else  return 
            self.getNotificationSettings()
            if err != nil 
                //Something bad happend
                 print("Erroo ocured......")
             else 
                print(" Success.........All good")
                UNUserNotificationCenter.current().delegate = self
                Messaging.messaging().delegate = self   // it is very important to Generate Firebase registration token, otherwise "didReceiveRegistrationToken" method will not called.

                DispatchQueue.main.async 
                    UIApplication.shared.registerForRemoteNotifications()
                
            
        

         FirebaseApp.configure()
      return true
    

    func getNotificationSettings() 
        UNUserNotificationCenter.current().getNotificationSettings  (settings) in
            print("Notification settings: \(settings)")
            guard settings.authorizationStatus == .authorized else  return 
            DispatchQueue.main.async(execute:  UIApplication.shared.registerForRemoteNotifications() )
        
    

    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String)
    
        print("Firebase registration token::::::: \(fcmToken)")
        UserDefaults.standard.set(fcmToken, forKey: "deviceToken")

    

    func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) 
        print("Received data message: \(remoteMessage.appData)")
    



    func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) 
        NSLog("[RemoteNotification] didRefreshRegistrationToken: \(fcmToken)")
    


    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) 
        // Print the error to console (you should alert the user that registration failed)
        print("APNs registration failed: \(error)")
    

    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) 
        //NSLog("[RemoteNotification] applicationState: \(applicationStateString) didReceiveRemoteNotification for ios9: \(userInfo)")
        if UIApplication.shared.applicationState == .active 
            //TODO: Handle foreground notification
         else 
            //TODO: Handle background notification
        
        // Print full message.
        print(userInfo)
    



    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) 
        // show the notification alert (banner), and with sound
        completionHandler([.alert, .sound])
    



    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) 
        // tell the app that we have finished processing the user’s action / response
        let application = UIApplication.shared
        if(application.applicationState == .active)
        print("user tapped the notification bar when the app is in foreground")
        
        if(application.applicationState == .inactive)
        
        print("user tapped the notification bar when the app is in background")
        
        completionHandler()
    





  func applicationWillResignActive(_ application: UIApplication) 

    
  func applicationDidEnterBackground(_ application: UIApplication) 

    

    func applicationWillEnterForeground(_ application: UIApplication) 
        // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
    



    func applicationWillTerminate(_ application: UIApplication) 
        self.saveContext()
    

【参考方案1】：

需要执行几个步骤来测试推送通知：

确保使用真实设备进行测试 您可以在函数 didRegisterForRemoteNotificationsWithDeviceToken 中获取远程实例 ID，如下所示，然后使用 Firebase 控制台将推送通知直接发送到设备令牌：

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) 
    InstanceID.instanceID().instanceID  (result, error) in
        if let error = error 
            print("Error fetching remote instange ID: \(error)")
         else if let result = result 
            print("Remote instance ID token: \(result.token)")

如果不起作用，请检查您是否在 Firebase 控制台设置中上传了正确的 APNs 身份验证密钥或 APNs 证书。

【参考方案2】：

**首先您应该检查所有证书类型的东西是否正确** 之后在 appdelegate 中

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool 
    // START register for notifications
        if #available(iOS 10.0, *) 
            // For iOS 10 display notification (sent via APNS)
            UNUserNotificationCenter.current().delegate = self

            let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
            UNUserNotificationCenter.current().requestAuthorization(
                options: authOptions,
                completionHandler: _, _ in )
         else 
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        

        application.registerForRemoteNotifications()        
        // END register for notifications


func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) 
    InstanceID.instanceID().instanceID  (result, error) in
        if let error = error 
            print("Error fetching remote instance ID: \(error)")
         else if let result = result 
            print("Result \(result)")
        
    


func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) 
    let deviceTokenString = deviceToken.hexString

还将您的 p.12 文件上传到 firebase 控制台

【讨论】：

我已经完成了所有的步骤 n 并且我已经将 .p12 文件上传到了 firebase 控制台，仍然无法收到通知
