我正在使用 Expo Managed Workflow 和“expo-notifications”模块向我的应用程序的用户发送推送通知。我已经在我的应用程序中根据文档创建了最小的复制品,并且在接收推送通知时遇到了问题。预定的本地通知工作正常并按预期显示。我还提取了我的 FCM 推送令牌以直接通过 FCM 发送通知,这也按预期工作。
我添加了日志记录以显示推送单/收据状态,并且两者都标记为“正常”,所以我不确定如何继续。

日志输出示例:

}
Reciept : Object {
"2fbfdd91-53a0-4199-ac32-b53131d72933": Object {
"status": "ok",
},
}
我知道博览会文档说
Even if a receipt's status says ok, this doesn't guarantee that the device has received the message; "ok" in a push receipt means that the Android or iOS push notification service successfully received the notification.
但是,我能够直接从 FCM 仪表板发送的事实表明我与我的设备通信应该没有问题。
作为参考,我正在真实的 Android 设备上运行 EAS 开发版本。
你解决这个问题了吗?如果是这样,怎么办?我对世博会通知也有同样的问题。博览会通知工具和端点 (https://api.expo.dev/v2/push/send) 返回 200,但在仪表板上 (https://expo.dev/accounts/[org]/projects/[项目]/push-notifications)每个通知都被标记为失败,并且没有日志可以让我检查我的配置有什么问题(尽管我遵循了官方文档)
