获取基于事件的统计信息

本主题提供用于获取基于事件的统计信息的示例代码。

API 公开各种级别的批处理以获取基于事件的统计信息。最佳做法是使用适合你需求的批处理 API 尽可能减少调用。

本主题涵盖以下内容：

• 为单个用户和单个 SCID 获取一个统计信息
• 为单个用户和单个 SCID 获取多个统计信息
• 为多个用户和单个 SCID 获取多个统计信息
• 为多个 SCID 中的多个用户获取多个统计信息

为单个用户和单个 SCID 获取一个统计信息

以下示例代码显示如何读取单个用户的统计信息。

平面 C API

auto asyncBlock = std::make_unique<XAsyncBlock>();
asyncBlock->queue = queue;
asyncBlock->callback = [](XAsyncBlock* asyncBlock)
{
    std::unique_ptr<XAsyncBlock> asyncBlockPtr{ asyncBlock }; // Take over ownership of the XAsyncBlock*.
    size_t resultSize;
    HRESULT hr = XblUserStatisticsGetSingleUserStatisticResultSize(asyncBlock, &resultSize);

    if (SUCCEEDED(hr))
    {
        std::vector<char> buffer(resultSize, 0);
        XblUserStatisticsResult* result{};

        hr = XblUserStatisticsGetSingleUserStatisticResult(asyncBlock, resultSize, buffer.data(), &result, nullptr);

        if (SUCCEEDED(hr) && result->serviceConfigStatisticsCount > 0 && result->serviceConfigStatistics->statisticsCount > 0)
        {
            int64_t userStatValue = atoll(result->serviceConfigStatistics[0].statistics[0].value);
            // You can now show or store userStatValue.
        }
    }
};

HRESULT hr = XblUserStatisticsGetSingleUserStatisticAsync(
    xboxLiveContext,
    xboxUserId,
    scid,
    statisticName.c_str(),
    asyncBlock.get()
);
if (SUCCEEDED(hr))
{
    // The call succeeded, so release the std::unique_ptr ownership of XAsyncBlock* because the callback will take over ownership.
    // If the call fails, the std::unique_ptr will keep ownership and delete the XAsyncBlock*.
    asyncBlock.release();
}

为单个用户和单个 SCID 获取多个统计信息

以下示例代码演示如何在一个 HTTP 调用中读取单个用户的多个统计信息。

平面 C API

auto asyncBlock = std::make_unique<XAsyncBlock>();
asyncBlock->queue = queue;
asyncBlock->callback = [](XAsyncBlock* asyncBlock)
{
    std::unique_ptr<XAsyncBlock> asyncBlockPtr{ asyncBlock }; // Take over ownership of the XAsyncBlock*.
    size_t resultSize;
    HRESULT hr = XblUserStatisticsGetSingleUserStatisticsResultSize(asyncBlock, &resultSize);

    if (SUCCEEDED(hr))
    {
        std::vector<char> buffer(resultSize, 0);
        XblUserStatisticsResult* results{};

        hr = XblUserStatisticsGetSingleUserStatisticsResult(asyncBlock, resultSize, buffer.data(), &results, nullptr);
        if (SUCCEEDED(hr))
        {
            // You can now use the XblUserStatisticsResult array in results.
        }
    }

};

const char* statisticNames[2] = {};
statisticNames[0] = statisticName1.c_str();
statisticNames[1] = statisticName2.c_str();

HRESULT hr = XblUserStatisticsGetSingleUserStatisticsAsync(
    xboxLiveContext,
    xboxUserId,
    scid,
    statisticNames, 2, 
    asyncBlock.get()
);
if (SUCCEEDED(hr))
{
    // The call succeeded, so release the std::unique_ptr ownership of XAsyncBlock* because the callback will take over ownership.
    // If the call fails, the std::unique_ptr will keep ownership and delete the XAsyncBlock*.
    asyncBlock.release();

为多个用户和单个 SCID 获取多个统计信息

下面的示例代码演示如何在一次 HTTP 调用中读取多个用户的多个统计信息。

auto asyncBlock = std::make_unique<XAsyncBlock>();
asyncBlock->queue = queue;
asyncBlock->callback = [](XAsyncBlock* asyncBlock)
{
    std::unique_ptr<XAsyncBlock> asyncBlockPtr{ asyncBlock }; // Take over ownership of the XAsyncBlock*.
    size_t resultSize;
    HRESULT hr = XblUserStatisticsGetMultipleUserStatisticsResultSize(asyncBlock, &resultSize);

        size_t resultsCount = 0;

        hr = XblUserStatisticsGetMultipleUserStatisticsResult(asyncBlock, resultSize, buffer.data(), &results, &resultsCount, nullptr);

        // Process results array to read the user stats data.
        for (size_t iResult = 0; iResult < resultsCount; iResult++)
        {
            LogToFile("%d", results[iResult].xboxUserId);

为多个 SCID 中的多个用户获取多个统计信息

下面的示例代码演示如何使用 Xbox 服务 API (XSAPI) 在仅使用一次调用的情况下从单个服务配置中读取多个统计信息。

平面 C API

auto asyncBlock = std::make_unique<XAsyncBlock>();
asyncBlock->queue = queue;
asyncBlock->callback = [](XAsyncBlock* asyncBlock)
{
    std::unique_ptr<XAsyncBlock> asyncBlockPtr{ asyncBlock }; // Take over ownership of the XAsyncBlock*.
    size_t resultSize;
    HRESULT hr = XblUserStatisticsGetMultipleUserStatisticsForMultipleServiceConfigurationsResultSize(asyncBlock, &resultSize);

    if (SUCCEEDED(hr))
    {
        std::vector<char> buffer(resultSize, 0);
        XblUserStatisticsResult* results{};
        size_t resultsCount = 0;

        hr = XblUserStatisticsGetMultipleUserStatisticsForMultipleServiceConfigurationsResult(asyncBlock, resultSize, buffer.data(), &results, &resultsCount, nullptr);

        if (SUCCEEDED(hr))
        {
            for (size_t i = 0; i < resultsCount; i++)
            {
                // Log results.
                std::stringstream stream;

                    }
                }

HRESULT hr = XblUserStatisticsGetMultipleUserStatisticsForMultipleServiceConfigurationsAsync(
    xboxLiveContext,
    xuids, 2,
    requestedStats, 1,
    asyncBlock.get()
