WinHttp 提交协议头和cookie例子

以下是一个使用WinHttpAddRequestHeaders函数提交协议头和cookie的示例代码：

#include <Windows.h>
#include <Winhttp.h>
#include <iostream>

#pragma comment (lib, "winhttp.lib")

int main()
{
    HINTERNET hSession = WinHttpOpen(L"WinHTTP Example/1.0", WINHTTP_ACCESS_TYPE_DEFAULT_PROXY, WINHTTP_NO_PROXY_NAME, WINHTTP_NO_PROXY_BYPASS, 0);
    if (!hSession)
    {
        std::cout << "Error: Failed to open WinHTTP session." << std::endl;
        return 1;
    }

    HINTERNET hConnect = WinHttpConnect(hSession, L"www.example.com", INTERNET_DEFAULT_HTTPS_PORT, 0);
    if (!hConnect)
    {
        std::cout << "Error: Failed to connect to server." << std::endl;
        WinHttpCloseHandle(hSession);
        return 1;
    }

    HINTERNET hRequest = WinHttpOpenRequest(hConnect, L"GET", L"/", NULL, WINHTTP_NO_REFERER, WINHTTP_DEFAULT_ACCEPT_TYPES, WINHTTP_FLAG_SECURE);
    if (!hRequest)
    {
        std::cout << "Error: Failed to open HTTP request." << std::endl;
        WinHttpCloseHandle(hConnect);
        WinHttpCloseHandle(hSession);
        return 1;
    }

    LPCWSTR headers = L"Content-Type: application/json\r\nAuthorization: Bearer <access_token>\r\nCookie: sessionid=<session_id>; csrftoken=<csrf_token>\r\n";
    if (!WinHttpAddRequestHeaders(hRequest, headers, (DWORD)-1L, WINHTTP_ADDREQ_FLAG_REPLACE))
    {
        std::cout << "Error: Failed to add request headers." << std::endl;
        WinHttpCloseHandle(hRequest);
        WinHttpCloseHandle(hConnect);
        WinHttpCloseHandle(hSession);
        return 1;
    }

    if (!WinHttpSendRequest(hRequest, WINHTTP_NO_ADDITIONAL_HEADERS, 0, WINHTTP_NO_REQUEST_DATA, 0, 0, NULL))
    {
        std::cout << "Error: Failed to send HTTP request." << std::endl;
        WinHttpCloseHandle(hRequest);
        WinHttpCloseHandle(hConnect);
        WinHttpCloseHandle(hSession);
        return 1;
    }

    if (!WinHttpReceiveResponse(hRequest, NULL))
    {
        std::cout << "Error: Failed to receive HTTP response." << std::endl;
        WinHttpCloseHandle(hRequest);
        WinHttpCloseHandle(hConnect);
        WinHttpCloseHandle(hSession);
        return 1;
    }

    // Do something with the response...

    WinHttpCloseHandle(hRequest);
    WinHttpCloseHandle(hConnect);
    WinHttpCloseHandle(hSession);

    return 0;
}

在上面的示例中，我们使用了WinHttpAddRequestHeaders函数来添加了三个请求头：Content-Type、Authorization和Cookie。其中，Authorization字段用于传递访问令牌，Cookie字段用于传递会话ID和CSRF令牌。请注意，这些值都是虚构的，需要根据实际情况进行替换。
