# PartyLocalUser::GetEntityId

> 获取与此本地用户关联的 PlayFab 实体 ID。

获取与此本地用户关联的 PlayFab 实体 ID。

## Syntax

```cpp theme={null}
PartyError GetEntityId(  
    PartyString* entityId  
)  
```

### Parameters

**`entityId`**   [PartyString\*](/services/playfab/multiplayer/networking/reference/typedefs)\
*library-allocated output*

用户的输出实体 ID。

### Return value

PartyError

如果调用成功，则返回 `c_partyErrorSuccess`；否则返回错误代码。可通过 [PartyManager::GetErrorMessage()](/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_geterrormessage) 检索错误代码的可读形式。

## Remarks

检索到的 PlayFab 实体 ID 与标题通过 [PartyManager::CreateLocalUser()](/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_createlocaluser) 或 [PartyManager::CreateLocalUserWithEntityType()](/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_createlocaluserwithentitytype) 提供的实体 ID 相同。这与表示实体的 `PFEntityKey` 结构的 *id* 字段中的值相同。从 [GetEntityType()](/services/playfab/multiplayer/networking/reference/classes/PartyLocalUser/methods/partylocaluser_getentitytype) 返回的值将表示 `PFEntityKey` 的另一半。<br /><br /> 实体 ID 字符串的内存在本地用户的生命周期内保持有效，即直到其 [PartyDestroyLocalUserCompletedStateChange](/services/playfab/multiplayer/networking/reference/structs/partydestroylocalusercompletedstatechange) 已通过 [PartyManager::StartProcessingStateChanges()](/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_startprocessingstatechanges) 提供，并且所有引用本地用户的状态更改都已返回到 [PartyManager::FinishProcessingStateChanges()](/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_finishprocessingstatechanges)。
