在APNs Cert更改后，推送通知不从FCM发送

提问于

在我的一个证书过期之前，我没有将从FCM发送推送通知到我的iOS应用程序的问题 . 更改后，FCM不再提供消息 . 我读了这篇文章（https://firebase.googleblog.com/2017/01/debugging-firebase-cloud-messaging-on.html），这是我到目前为止所经历的验证步骤，但现在我正在敲打我的头...

  • 注释掉任何connectToFCM函数

  • 已下载Pusher并成功使用APNs证书向设备发送通知

  • 成功地对FCM进行了卷曲调用（下面的回复）

  • {"multicast_id"：7774794018682407760，"success"：1，"failure"：0，"canonical_ids"：0，"results"：[{_ "message_id"："0:1493321644068397%b76e8527b76e8527"}]}

  • 尝试重新创建开发和 生产环境 证书

  • 尝试使用和不使用密码从钥匙串导出它们

任何人都有这种超级令人沮丧的事情的经验，并就如何进行提出建议？

同样值得注意的是我无法删除APNs证书，我看到了选项，但它显示为灰色，我无法选择它 .

    这有助于理解流程 .

    您已经测试过APN发送给应用程序 . 所以证书很好 .

    从您链接的the blog，通过进行卷曲呼叫获得成功的响应意味着FCM正在接收该消息 . 这并不意味着消息正在传递给APN .

    使用Firebase通知面板直接发送消息，以查看FCM是否正在与APN进行通信 .

    如果可行，则表示您的邮件格式存在问题 .

    如果它不起作用 .

    确保：

    • 消息优先级设置为 high ，因此会立即发送 .

    • “content_available”：是的

    • 卸载并重新安装应用程序

    • 检查您的服务器代码 .

    您可以创建一个APNs密钥，并将其用于所有应用程序，而不是使用APNS证书进行推送通知 .

    APN使用Apple推送通知服务来处理您的通知请求 . 一键用于所有应用 . 有关更多信息，请参阅“本地和远程通知编程指南” .

    甚至FCM都支持这一点 . 现在，您可以避免为每个应用程序ID创建APNS证书 .

    请在YourProjectSetting => cloudmessaging => iOS app配置中更新您的APNs证书（ 生产环境 和开发） . Firebase Cloud Messaging可以使用APNs身份验证密钥或APNs证书来连接APN

    注意：确认您的项目凭据（SenderID，旧服务器密钥，服务器密钥） .

    HTTP POST请求：用于发送通知 .

    在 AppDelegate.swift 中添加以下代码

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
            self.fcmInitialSetup(application)
            return true

                let uns: UIUserNotificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
                application.registerUserNotificationSettings(uns)
                application.registerForRemoteNotifications()

            } else {
                let settings: UIUserNotificationSettings =
                    UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
                application.registerUserNotificationSettings(settings)
            }

            application.registerForRemoteNotifications()

            // [END register_for_notifications]

            FIRApp.configure()

            // Add observer for InstanceID token refresh callback.
            NotificationCenter.default.addObserver(self, selector: #selector(self.tokenRefreshNotification), name: NSNotification.Name.firInstanceIDTokenRefresh, object: nil)
