Swift 5 - 无法通过 FCM 接收推送通知

Question

我无法收到推送通知，这是我的有效负载

{
  "to": "erOZW7CN....(fcm token)",
  "data": {
    "body": "Incoming-Call",
    "title": "AppName",
    "type": "incoming-call",
    "number": "0212222222"
  },
  "aps": {
    "alert": {
      "title": "AppName",
      "body": "Incoming-Call"
    }
  }
}

data 部分适用于 Android。当我使用notification 而不是aps 时，它可以工作，但Android 端会出现问题。所以我需要使用aps 来检测请求。我做了很多研究，但找不到任何解决方案。

这是我的 AppDelegate

import UIKit
import CoreData
import Firebase
import Network


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


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        
        FirebaseApp.configure()
        
        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()
        Messaging.messaging().delegate = self
        
        return true
    }
    

    
    // MARK: UISceneSession Lifecycle

    func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
        return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
    }

    @available(iOS 13.0, *)
    func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {

    }
    
    lazy var persistentContainer: NSPersistentContainer = {
        let container = NSPersistentContainer(name: "Database")
        container.loadPersistentStores(completionHandler: { (storeDescription, error) in
            if let error = error as NSError? {
                fatalError("Unresolved error \(error), \(error.userInfo)")
            }
        })
        return container
    }()
    
    func saveContext () {
        let context = persistentContainer.viewContext
        if context.hasChanges {
            do {
                try context.save()
            } catch {
                let nserror = error as NSError
                fatalError("Unresolved error \(nserror), \(nserror.userInfo)")
            }
        }
    }

    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        Messaging.messaging().apnsToken = deviceToken
    }
    

    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
        print("Firebase registration token: \(fcmToken)")

        let dataDict:[String: String] = ["token": fcmToken]
        NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
        UserDefaults.standard.set(fcmToken, forKey: "fcmToken")
    }
    
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        print("Push Received: \(userInfo)")
        //TODO: CALLKIT DETECT
    }
}

注意：我正在从 Postman 发送请求

在这里找到解决方案会很棒。谢谢。

通过 FCM 或 APNS 发送推送通知时，生成您的有效负载，如下所示。

基本负载：iOS 和 Android（通过 FCM 发送）

{
  "message": {
      "notification": {
        "body": "YOUR MESSAGE BODY HERE",
        "title": "YOUR MESSAGE TITLE HERE"
      }
  }
}

基本负载：iOS（通过 APNS 发送）

{
  "aps": {
    "alert": {
      "body": "YOUR MESSAGE BODY HERE",
      "title": "YOUR MESSAGE TITLE HERE"
    }
  }
}

注意：

在didReceiveRemoteNotification 函数中，您将收到符合 iOS 风格的有效负载。
