在 Windows 10、1803 中，可以从符合标准的 C++ 调用 WinRT。不再需要 C++ /CX 语言扩展。

我已经知道如何使用 HttpRequestMessage 类向服务器发送发布请求：

#pragma comment(lib, "windowsapp")

#include "pch.h"
#include "winrt/Windows.Web.Http.Filters.h"
#include "winrt/Windows.Web.Http.Headers.h"
#include <winrt/Windows.Foundation.h>
#include <winrt/Windows.Foundation.Collections.h>
#include <string_view>

using namespace winrt;
using namespace Windows::Foundation;
using namespace Windows::Web::Http;
using namespace Windows::Web::Http::Filters;
using namespace Windows::Web::Http::Headers;
using namespace Windows::Foundation::Collections;
using namespace std::literals;
using namespace std;


IAsyncAction HttpClientExample(Uri uri)
{
    HttpBaseProtocolFilter filter;
    HttpClient httpClient(filter);
    HttpRequestMessage loginRequest(HttpMethod::Post(), uri);

    try
    {

        auto response{ co_await httpClient.SendRequestAsync(loginRequest) };
        HttpCookieCollection cookieCollection =     filter.CookieManager().GetCookies(uri);
        wcout << cookieCollection.Size() << L" cookies found." << endl;

        for (HttpCookie cookie : cookieCollection) {
            wcout << L"Name: " << cookie.Name().c_str() << endl;
            wcout << L"Domain: " << cookie.Domain().c_str() << endl;
            wcout << L"Path: " << cookie.Path().c_str() << endl;
            wcout << L"Value: " << cookie.Value().c_str() << endl;
        }
    }
    catch (winrt::hresult_error const& ex)
    {
        // Details in ex.message() and ex.to_abi().
    }
}

int main() {

    init_apartment();

    Uri uri{ L"http://www.google.com/"sv };

    HttpClientExample(uri);

    Sleep(10000);
}

如何使用 HttpFormUrlEncodedContent 设置自定义标题以及如何在 POST 正文中设置自定义内容？

谢谢您的帮助！
