ios - 提供的注册 token 未注册

Question

我正在尝试通过 Google 云功能为 iOS 发送推送通知，但它返回错误，提示提供的注册 token 未注册。但我已经通过调试我的应用程序进行了检查，并且 FCM 注册 token 是正确的。之后，我尝试通过提供 FCM token 通过 Firebase 控制台向单个设备发送推送通知，但由于 Unregistered registration token 而失败。为什么会发生这种情况，因为设备 FCM token 没有问题？

Answer 1

我认为这应该是一些粗心的错误，你应该确保以下几点:

1. token 与-[FIRMessagingDelegate messaging:(FIRMessaging *)messaging didReceiveRegistrationToken:(NSString *)fcmToken]相同

2. GoogleService-Info.plist 是 downloaded来自与您的 Firebase 推送控制台相同的帐户。

3. 更新到最新的 Firebase SDK。

来自 Google Firebase document是对您的错误的一些描述 The provided registration token is not registered。

The provided registration token is not registered. A previously valid registration token can be unregistered for a variety of reasons, including:

• The client app unregistered itself from FCM.
• The client app was automatically unregistered. This can happen if the user uninstalls the application or, on iOS, if the APNS Feedback Service reported the APNS token as invalid.
• The registration token expired. For example, Google might decide to refresh registration tokens or the APNS token may have expired for iOS devices.
• The client app was updated, but the new version is not configured to receive messages. For all these cases, remove this registration token and stop using it to send messages.
