使用.p8文件后未收到iOS Firebase云消息传递通知

Question

我按照以下所有步骤在App Delegate中添加了相应的导入和代码。我还确保在运行应用程序时允许接受通知。

按照以下步骤操作，为什么我从Firebase云消息传递控制台发送通知后无法收到通知？

1. 在我的开发者帐户中，我去了Certificates, Identifiers & Profiles
2. 在Keys下，我选择了All并点击了右上角的Add按钮（+）
3. 在Key Description下，我为签名密钥输入了一个唯一的名称
4. 在qazxsw poi下，我选择了qazxsw poi复选框，然后点击qazxsw poi然后点击Key Services
5. 我复制了APNs（在步骤7中使用）并点击Continue生成并下载Confirm密钥
6. 我去了Key ID，点击了Download> .p8> Firebase
7. 在Gear Icon> Project Settings下我去了第一部分Cloud Messaging（不是APNs证书），选择了iOS app configuration并上传了APNs Authentication Key键，APNs Authentication Key和我的Upload
8. 在我的Xcode项目中，我去了.p8> Key ID，把它变成了Team Id，并检查了Capabilities
9. 虽然仍然在Background Modes> On，并把它变成Remote Notifications
10. 在AppDelegate中，我添加了Capabilities，Push Notifications，On，注册了import UserNotifications并添加了以下代码。

我在下面的所有打印声明中添加了断点，在我从Firebase发送消息后，没有一个被击中。

import FirebaseMessaging

消息会成功发送，如下图所示，但我从未收到过。

import Firebase

我认为您还应该将此添加到您的代码中，否则您将不会收到推送通知。 Firebase现在需要apns令牌向您发送推送。

UNUserNotificationCenterDelegate

Answer 2

好像你错过了一些FCM正常工作的配置。

从我看到你没有将令牌发送到firebase并且你没有注册FCM。

有关更多详细信息，请参阅

import UserNotifications
import FirebaseMessaging
import Firebase

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {

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

        FirebaseApp.configure()

        UNUserNotificationCenter.current().delegate = self

        if #available(iOS 10.0, *) {

            UNUserNotificationCenter.current().requestAuthorization(options: [.sound,.alert,.badge]) {
            [weak self] (granted, error) in

                if let error = error {
                    print(error.localizedDescription)
                    return
                }

                print("Success")
            }
            application.registerForRemoteNotifications()

        } else {

            let notificationTypes: UIUserNotificationType = [.alert, .sound, .badge]
            let notificationSettings = UIUserNotificationSettings(types: notificationTypes, categories: nil)
            application.registerForRemoteNotifications()
            application.registerUserNotificationSettings(notificationSettings)
        }
    }

    // MARK:- UNUserNotificationCenter Delegates
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

        Messaging.messaging().setAPNSToken(deviceToken, type: MessagingAPNSTokenType.unknown)

        var token = ""
        for i in 0..<deviceToken.count{
            token = token + String(format: "%02.2hhx", arguments: [deviceToken[i]])
        }
        print("Registration Succeded! Token: \(token)")
    }

    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        print("Notifcation Registration Failed: \(error.localizedDescription)")
    }

    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {

        if let gcm_message_id = userInfo["gcm_message_id"]{
            print("MessageID: \(gcm_message_id)")
        }

        print(userInfo)
    }

    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

        completionHandler(.alert)

        print("Handle push from foreground \(notification.request.content.userInfo)")

        let dict = notification.request.content.userInfo["aps"] as! NSDictionary
        let d = dict["alert"] as! [String:Any]
        let title = d["title"] as! String
        let body = d["body"] as! String
        print("Title:\(title) + Body:\(body)")
        showFirebaseNotificationAlertFromAppDelegate(title: title, message: body, window: self.window!)
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

        print("\(response.notification.request.content.userInfo)")

        if response.actionIdentifier == "yes"{
            print("True")
        }else{
            print("False")
        }
    }

    func showFirebaseNotificationAlertFromAppDelegate(title: String, message: String, window: UIWindow){
        let alert = UIAlertController(title: title, message: message, preferredStyle: .alert)
        let action = UIAlertAction(title: "OK", style: .default, handler: nil)
        alert.addAction(action)
        window.rootViewController?.present(alert, animated: true, completion: nil)
    }
}

文档。

要通过firebase发送推送消息，您需要拥有FCM令牌。您正在使用的令牌是来自APNS服务器的令牌，您需要将其转发到firebase。

Answer 3

我得到了

我应该在

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

之前添加https://firebase.google.com/docs/cloud-messaging/ios/client

我还必须在Messaging Delegate中添加以接收FCM注册令牌。

在answer from here里面添加Messaging.messaging().delegate = self

FirebaseApp.configure()

****同样在AppDelegate文件的底部添加Messaging Delegate及其方法。这是收到didFinishLaunching的地方：

Messaging.messaging().delegate = self
