从 Firebase 云消息传递获取 FCM 密钥时出现错误

Question

我正在尝试从 Firebase 云消息传递中获取用于推送通知的 FCM 密钥，但得到 nil &我在下面提到的错误

** 错误：- 在检索发件人 ID“836092823410”的 FCM 令牌之前未设置 APNS 设备令牌。对此 FCM 令牌的通知将不会通过 APNS 传送。设置 APNS 设备令牌后，请务必重新检索 FCM 令牌。 **

这是我的 Appdelegate 扩展，它可以工作：

import UIKit
import Firebase


extension AppDelegate {
    func setupFirebase(application: UIApplication) {
        
        FirebaseApp.configure()
        FirebaseConfiguration.shared.setLoggerLevel(.min)
        Messaging.messaging().delegate = self
        Messaging.messaging().token { token, error in
          if let error = error {
            print("Error fetching FCM registration token: \(error)")
          } else if let token = token {
            print("FCM registration token: \(token)")
          }
        }
        
        UNUserNotificationCenter.current().delegate = self
        
        let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
        UNUserNotificationCenter.current().requestAuthorization(
            options: authOptions,
            completionHandler: {_, _ in })
        
        application.registerForRemoteNotifications()
    }
    // [START receive_message]
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
        
    }
    
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                     fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        completionHandler(UIBackgroundFetchResult.newData)
    }
    // [END receive_message]
    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
    }
    
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        print("APNs token retrieved: \(deviceToken)")
        UserDefaults.standard.set(deviceToken, forKey: APNS_TOKEN)
        Messaging.messaging().apnsToken = deviceToken
    }
}

extension AppDelegate : UNUserNotificationCenterDelegate {
    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                willPresent notification: UNNotification,
                                withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        let userInfo = notification.request.content.userInfo
        if let messageID = userInfo[fcmMessageIDKey] {
            print("Message ID: \(messageID)")
        }
        print(userInfo)
        completionHandler([[.alert, .sound]])
    }
    
    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                didReceive response: UNNotificationResponse,
                                withCompletionHandler completionHandler: @escaping () -> Void) {
        let userInfo = response.notification.request.content.userInfo
        if let messageID = userInfo[fcmMessageIDKey] {
            print("Message ID: \(messageID)")
        }
        print(userInfo)
        
        completionHandler()
    }
}

extension AppDelegate : MessagingDelegate {
    // [START refresh_token]
    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String?) {
        print("Firebase registration token: \(String(describing: fcmToken))")

        if let _fcmToken = fcmToken {
            UserDefaults.standard.set(_fcmToken, forKey: FCM_TOKEN)
          
            let dataDict:[String: String] = ["token": _fcmToken]
            NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
        }
        
    }
}

您可以调用“didFinishLaunchingWithOptions”

setupFirebase(application: application)
