没有收到来自 Firebase 控制台的推送通知

Question

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

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。

**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
