# XStoreQueryProductForPackageAsync

> XStoreQueryProductForPackageAsync

# XStoreQueryProductForPackageAsync

检索指定包的商店产品信息。

## 语法

```cpp theme={null}
HRESULT XStoreQueryProductForPackageAsync(  
         const XStoreContextHandle storeContextHandle,  
         XStoreProductKind productKinds,  
         const char* packageIdentifier,  
         XAsyncBlock* async  
)  
```

### 参数

*storeContextHandle*   \_In\_\
类型：XStoreContextHandle

[XStoreCreateContext](/reference/system/xstore/functions/xstorecreatecontext) 为用户返回的商店上下文句柄。

*productKinds*   \_In\_\
类型：[XStoreProductKind](/reference/system/xstore/enums/xstoreproductkind)

要查找的产品类型。

*packageIdentifier*   \_In\_z\_\
类型：char\*

唯一标识商店包的字符串。有关包标识符的详细信息，请参阅[管理和许可可下载内容 (DLC)](https://learn.microsoft.com/gaming/gdk/docs/store/commerce/fundamentals/xstore-manage-and-license-optional-packages)。

*async*   \_Inout\_\
类型：[XAsyncBlock\*](/reference/system/xasync/structs/xasyncblock)

定义正在完成的异步工作的 [XAsyncBlock](/reference/system/xasync/structs/xasyncblock)。[XAsyncBlock](/reference/system/xasync/structs/xasyncblock) 可用于轮询调用的状态并检索调用结果。有关详细信息，请参阅 [XAsyncBlock](/reference/system/xasync/structs/xasyncblock)。

### 返回值

类型：HRESULT

HRESULT 成功或错误代码。

## 备注

要检索商店产品信息以及此函数调用的执行结果，请在调用此函数之后调用 [XStoreQueryProductForPackageResult](/reference/system/xstore/functions/xstorequeryproductforpackageresult)。

以下代码片段展示了检索包产品信息的示例。

```cpp theme={null}
void CALLBACK QueryProductForPackageCallback(XAsyncBlock* asyncBlock)
{
    XStoreProductQueryHandle queryHandle = nullptr;

    HRESULT hr = XStoreQueryProductForPackageResult(
        asyncBlock,
        &queryHandle);

    if (FAILED(hr))
    {
        printf("Failed retrieve the product query handle: 0x%x\r\n", hr);
        XStoreCloseProductsQueryHandle(queryHandle);
        return;
    }

    // Use result of query

     XStoreCloseProductsQueryHandle(queryHandle);
}

void QueryProductForPackage(XStoreContextHandle storeContextHandle, const char* packageIdentifier)
{
    auto asyncBlock = std::make_unique<XAsyncBlock>();
    ZeroMemory(asyncBlock.get(), sizeof(*asyncBlock));
    asyncBlock->queue = taskQueueHandle;
    asyncBlock->callback = QueryProductForPackageCallback;

    XStoreProductKind allProductKinds =
        XStoreProductKind::Consumable |
        XStoreProductKind::Durable |
        XStoreProductKind::Game |
        XStoreProductKind::Pass |
        XStoreProductKind::UnmanagedConsumable;

    HRESULT hr = XStoreQueryProductForPackageAsync(
        storeContextHandle,
        allProductKinds,
        packageIdentifier,
        asyncBlock.get());

    if (FAILED(hr))
    {
        printf("Failed to get product for package: 0x%x\r\n", hr);
        return;
    }
}


```
