使用商店服务管理定向优惠

2025-06-10

如果您在合作伙伴中心的应用程序的页创建了 >，请在应用的代码中使用 Microsoft Store 定向优惠 API 来检索信息，以帮助您实现该定向优惠的应用内体验。有关目标产品/服务以及如何在仪表板中创建它们的详细信息，请参阅使用定向产品/服务最大化参与度和转换。

目标产品/服务 API 是一个简单的 REST API，可用于获取当前用户可用的目标产品/服务，具体取决于用户是否是目标产品/服务的客户细分的一部分。若要在应用的代码中使用此 API，请执行以下步骤：

获取您应用中当前登录用户的 Microsoft 帐户令牌。
获取当前用户的目标产品/服务。
为与某个目标产品/服务关联的加载项实现应用内购买体验。有关实现应用内购买的详细信息，请参阅此文章。

有关演示所有这些步骤的完整代码示例，请参阅本文末尾的代码示例。以下部分提供有关每个步骤的更多详细信息。

获取当前用户的Microsoft帐户令牌

在应用程序的代码中，获取当前登录用户的 Microsoft 帐户 (MSA) 令牌。您必须在 Microsoft Store 定向优惠 API 的 Authorization 请求标头中传递此令牌。应用商店使用此令牌来检索当前用户可用的目标产品/服务。

若要获取 MSA 令牌，请使用 WebAuthenticationCoreManager 类，并通过范围 devcenter_implicit.basic,wl.basic请求令牌。以下示例演示如何执行此操作。此示例摘录自完整示例，并要求使用完整示例中提供的语句。

private async Task<string> GetMicrosoftAccountTokenAsync()
{
    var msaProvider = await WebAuthenticationCoreManager.FindAccountProviderAsync(
        "https://login.microsoft.com", "consumers");

    WebTokenRequest request = new WebTokenRequest(msaProvider, "devcenter_implicit.basic,wl.basic");
    WebTokenRequestResult result = await WebAuthenticationCoreManager.RequestTokenAsync(request);

    if (result.ResponseStatus == WebTokenRequestStatus.Success)
    {
        return result.ResponseData[0].Token;
    }
    else
    {
        return string.Empty;
    }
}

有关获取 MSA 令牌的详细信息，请参阅 Web 帐户管理器。

获取当前用户的目标优惠

为当前用户提供 MSA 令牌后，调用 https://manage.devcenter.microsoft.com/v2.0/my/storeoffers/user URI 的 GET 方法以获取当前用户的可用目标产品/服务。有关此 REST 方法的详细信息，请参阅获取目标产品/服务。

此方法将返回与当前用户可用的目标优惠相关联的加载项的产品 ID。利用此信息，可以将一个或多个目标产品/服务作为应用内购买提供给用户。

以下示例演示如何获取当前用户的目标产品/服务。此示例是完整示例的摘录。它需要由 Newtonsoft 提供的 Json.NET 库，以及在完整示例中提供的其他类和语句。

private async Task<List<TargetedOfferData>> GetTargetedOffersForUserAsync(string msaToken)
{
    if (string.IsNullOrEmpty(msaToken))
    {
        System.Diagnostics.Debug.WriteLine("Microsoft Account token is null or empty.");
        return null;
    }

    HttpClient httpClientGetOffers = new HttpClient();
    httpClientGetOffers.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", msaToken);
    List<TargetedOfferData> availableOfferData = null;

    try
    {
        string getOffersResponse = await httpClientGetOffers.GetStringAsync(new Uri(storeOffersUri));
        availableOfferData = 
            Newtonsoft.Json.JsonConvert.DeserializeObject<List<TargetedOfferData>>(getOffersResponse);
    }
    catch (Exception ex)
    {
        System.Diagnostics.Debug.WriteLine(ex.Message);
    }

    return availableOfferData;
}

下面的代码示例演示了以下任务：

获取当前用户的 MSA 令牌。
使用获取定向优惠方法获取当前用户的所有定向优惠。
购买与定向优惠关联的附加组件。

此示例需要 Newtonsoft 中的 Json.NET 库。此示例使用此库序列化和反序列化 JSON 格式的数据。
