# StartOrRecoverSession

> PlayFab 即時訊息的 StartOrRecoverSession SignalR 伺服器方法，可啟動工作階段，或在意外中斷連線後還原訂閱。

> [!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)。

啟動工作階段。

用戶端必須呼叫此方法來啟動工作階段，並取得代表該工作階段的 `Connection
Handle`。用戶端必須儲存此 `Connection Handle`，以便稍後用來為工作階段建立訂閱。

```text theme={null}
StartOrRecoverSessionResponse StartOrRecoverSession(StartOrRecoverSessionRequest request)
```

> [!TIP]
>
> 這是 SignalR 伺服器方法。請參閱從 SignalR 用戶端[呼叫伺服器方法的文件](https://learn.microsoft.com/en-us/aspnet/core/signalr/dotnet-client#call-hub-methods-from-client)。
