# AddEntityToSession SignalR 服务器方法

> 适用于 PlayFab 实时消息的 AddEntityToSession SignalR 服务器方法,可将另一个本地实体添加到共享会话,以支持多账户设备。

<Note>
  此处记录的 REST 和 SignalR API 比客户端 SDK 更复杂。除非这些 SDK 不能满足你的需求,否则请考虑使用 [Lobby C++ SDK](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/pflobby_members) 或 [Matchmaking C++ SDK](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmatchmaking/pfmatchmaking_members)。
</Note>

适用于多个实体登录到同一设备的场景。在启动会话的实体之外,向该会话添加一个额外的实体。这将允许客户端在共享会话上接收多个本地实体的消息。

```text theme={null}
SharedSessionResponse AddEntityToSession(SharedSessionRequest request)
```

<Tip>
  这是一个 SignalR 服务器方法。请参阅有关在 SignalR 客户端中[调用服务器方法](https://learn.microsoft.com/en-us/aspnet/core/signalr/dotnet-client#call-hub-methods-from-client)的文档。
