Firebase通知到具有FCM令牌的设备说已发送但未收到 [英] Firebase Notification To Device with FCM Token Says Sent but not received
问题描述
我尝试使用FCM令牌从Firebase通知控制台向特定设备发送简单的推送通知。 Firebase通知控制台显示通知已发送，但设备未收到通知。我已经尝试发送通知，然后等待查看控制台是否从 didReceiveRemoteNotification 进行日志记录，但通知过长（小时）显示为在Firebase控制台中发送即使我将优先级设置为 high ）。

权利&启用推送通知
我已经添加了推送权利并启用推送通知的背景模式，并将GoogleService-Info.plist添加到我的项目中。
发送通知的方法 b
我正在从Firebase通知控制台创建通知（如下所示），因此通知本身的结构应该没有问题。
有谁知道为什么通知是标记为已在Firebase通知控制台中发送，但未在设备上显示？
- 获取推送独立于Firebase服务。我使用这个工具。
- 确保你没有任何捆绑标识符命名空间冲突。因此，例如，具有appstore构建，testflight构建和/或在设备上开发应用程序构建的任何组合。删除所有应用程序的一个实例。软件包标识符是您的设备知道将推送通知路由到哪个应用程序的方式。
- 当所有其他项都失败时，我会尝试通过构建一个新的示例项目来隔离这个问题，并将其连接到一个新的Firebase项目，并查看是否可以缩小我的焦点在我的应用程序中没有任何其他业务逻辑推动工作。这有助于我向自己证明自己并没有疯狂，并向我证明，这并不是一个神秘的网络状况，导致我的悲哀。
我希望这可以帮助你，因为你的工作得到了一切。
I am attempting to send a simple push notification from the firebase notification console to a specific device using an FCM token. The firebase notification console shows the notification as sent but the device does not receive it. I have tried sending the notification and then waiting to see if the console logs from didReceiveRemoteNotification, but the notification takes too long (hours) to be shown as sent in the firebase console (even when I set the priority to high).

Entitlements & Enabling Push Notifications
I have added the push entitlements and enabled background modes for push notifications and added the GoogleService-Info.plist to my project.
Method for sending Notification
I am creating notification from the Firebase Notifications console (as shown below) so there should be no issue with the structure of the notification itself.
I have tried the following approaches to remedy the issue, but all have produced the same result:
Does anyone know why the notification is being marked as sent in the firebase notification console but not showing up on the device?
A couple of troubleshooting steps I use when working with push notifications are:
- Get push working independent of the firebase services first. I use this tool.
- Make sure that you dont have any bundle identifier namespace collisions. So for example having any combination of appstore build, testflight build, and / or develop build of an app on the device. Delete all but one instance of the app. The bundle identifier is how your device knows which app to route the push notification to.
- When all else fails - I try to isolate the issue by building a new sample project and hook it up to a new firebase project and see if I can narrow my focus down to just being able to get push working without any other business logic in my app. This helps me prove to my self that I haven't gone insane, and proves to me that it's not some mysterious network condition leading to my woes.
I hope this helps you as you work get it all figured out.
