# 訂閱資源以接收即時訊息

> 使用 StartOrRecoverSession 所取得的連線控制代碼，讓 PlayFab 大廳和配對用戶端透過即時訊息 SignalR 中樞訂閱資源主題。

> [!NOTE]
>
> 這裡記載的 REST 和 SignalR API 比用戶端 SDK 更複雜。除非這些 SDK 無法滿足您的需求，否則請考慮改用[大廳 C++ SDK](/zh-TW/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/pflobby_members) 或[配對 C++ SDK](/zh-TW/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmatchmaking/pfmatchmaking_members.md)。

用戶端[連線至 SignalR 中樞](/zh-TW/services/playfab/multiplayer/real-time-messages/signalr-hub.md#connecting-to-the-signalr-hub)並呼叫 [StartOrRecoverSession](/zh-TW/services/playfab/multiplayer/real-time-messages/server-methods/start-or-recover-session.md) 以接收 `Connection Handle` 之後，就可以訂閱主題並接收訊息。

訂閱大廳或配對資源時，用戶端需要提供啟動工作階段時所收到的 `Connection Handle`。如需啟動和管理工作階段的詳細資訊，請參閱 [SignalR 中樞](/zh-TW/services/playfab/multiplayer/real-time-messages/signalr-hub.md)概觀。
