研究方向

未指定任何 repository 檔案或測試。請從 FirebaseMessaging.getInstance.send 呼叫開始,將伺服器訊息 ID 和傳送日誌與 Notification Service Extension 的接收日誌進行比較。完成標準是確認重複是源自 SDK、Firebase Cloud Messaging,還是下游傳遞,並提供可重現的驗證或記錄在案的外部原因。

描述

api: messaging
Environment:
  • Operating System version: Java 8
  • Firebase SDK version: 10.11.0
  • Library version: 8.1.0
  • Firebase Product: messaging (auth, database, storage, etc)
Problem:

We're seeing multiple instances of a single message being sent via Cloud Messaging using the Firebase Admin SDK, and users seeing duplicates on iOS. We have logs both on the server side, directly before and after on the server side, and on the client side upon receipt in a Notification Service Extension.

We've verified through these logs (tied to data from user screenshots), that the message is sent only once on our server, we receive a success response from the Firebase SDK, and the user receives that exact notification twice.

Server Logs:
16:08:16.542 | al-pool-2228 |  INFO | w.SendNotificationWorker$ | 303 | 31ec5101-b43e-4519-99a1-9bb3650471c7: Successfully sent notification 2273480
16:08:16.537 | al-pool-7377 |  INFO | .n.NotificationDispatcher | 342 | Notification id 2273480 sent status true
16:08:16.537 | al-pool-7377 |  INFO | c.s.f.s.FirebaseService$  | 158 | Submitted notification to Firebase with messageId: projects/{redacted}/messages/{redacted} for notification id: 2273480

Client Logs:
16:08:21.092 AM -0700 |	INFO | {redacted} | NotificationService | did receive notification | notificationId = 2273480
16:08:21.091 AM -0700	| INFO | {redacted} | NotificationService | did receive notification | notificationId = 2273480
Relevant Code:
val messageId = FirebaseMessaging.getInstance.send(messageBuilder.build)
logger.info(s"Submitted notification to Firebase with messageId: $messageId for notification id: ${notificationId
          .getOrElse(0L)}")
