Set Cookie von Antwort in WinHttp

Question

Ich habe einen Code, der eine Post-Anfrage an einen Server, aber ich versuche, ein Cookie aus der Antwort setzen. (Nur für den Fall, ich bin eine Anfrage an eine BurningBoard Anmeldung tun)

Hier haben Sie meinen Code:

HttpsWebRequestPost("example.com", "/api.php?action=UserLogin", "loginUsername=" + USERNAME + "&loginPassword=" + PASSWORD + "&url=/index.php?page=Portal"); 

Und:

#pragma once 

#include <Windows.h> 
#include <WinHttp.h> 
#include <stdio.h> 
#include <iostream> //getchar 
#include <fstream> 

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

using namespace std; 

std::wstring get_utf16(const std::string &str, int codepage) 
{ 
    if (str.empty()) return std::wstring(); 
    int sz = MultiByteToWideChar(codepage, 0, &str[0], (int)str.size(), 0, 0); 
    std::wstring res(sz, 0); 
    MultiByteToWideChar(codepage, 0, &str[0], (int)str.size(), &res[0], sz); 
    return res; 
} 

string HttpsWebRequestPost(string domain, string url, string dat) 
{ 
    //Extra 
    LPSTR data = const_cast<char *>(dat.c_str());; 
    DWORD data_len = strlen(data); 


    wstring sdomain = get_utf16(domain, CP_UTF8); 
    wstring surl = get_utf16(url, CP_UTF8); 
    string response; 

    DWORD dwSize = 0; 
    DWORD dwDownloaded = 0; 
    LPSTR pszOutBuffer; 
    BOOL bResults = FALSE; 
    HINTERNET hSession = NULL, 
     hConnect = NULL, 
     hRequest = NULL; 

    // Use WinHttpOpen to obtain a session handle. 
    hSession = WinHttpOpen(L"WinHTTP Example/1.0", 
     WINHTTP_ACCESS_TYPE_DEFAULT_PROXY, 
     WINHTTP_NO_PROXY_NAME, 
     WINHTTP_NO_PROXY_BYPASS, 0); 

    // Specify an HTTP server. 
    if (hSession) 
     hConnect = WinHttpConnect(hSession, sdomain.c_str(), 
      INTERNET_DEFAULT_HTTP_PORT, 0); 

    // Create an HTTP request handle. 
    if (hConnect) 
     hRequest = WinHttpOpenRequest(hConnect, L"POST", surl.c_str(), 
      NULL, WINHTTP_NO_REFERER, 
      WINHTTP_DEFAULT_ACCEPT_TYPES, 
      0); 

    LPCWSTR additionalHeaders = L"Content-Type: application/x-www-form-urlencoded\r\n"; 
    DWORD headersLength = -1; 

    // Send a request. 
    if (hRequest) 
     bResults = WinHttpSendRequest(hRequest, 
      additionalHeaders, headersLength, 
      (LPVOID)data, data_len, 
      data_len, 0); 


    // End the request. 
    if (bResults) 
     bResults = WinHttpReceiveResponse(hRequest, NULL); 

    // Keep checking for data until there is nothing left. 
    if (bResults) 
    { 
     do 
     { 
      // Check for available data. 
      dwSize = 0; 
      if (!WinHttpQueryDataAvailable(hRequest, &dwSize)) 
       printf("Error %u in WinHttpQueryDataAvailable.\n", 
        GetLastError()); 

      // Allocate space for the buffer. 
      pszOutBuffer = new char[dwSize + 1]; 
      if (!pszOutBuffer) 
      { 
       printf("Out of memory\n"); 
       dwSize = 0; 
      } 
      else 
      { 
       // Read the data. 
       ZeroMemory(pszOutBuffer, dwSize + 1); 

       if (!WinHttpReadData(hRequest, (LPVOID)pszOutBuffer, 
        dwSize, &dwDownloaded)) 
        printf("Error %u in WinHttpReadData.\n", GetLastError()); 
       else 
        //printf("%s", pszOutBuffer); 
        response = response + string(pszOutBuffer); 
       // Free the memory allocated to the buffer. 
       delete[] pszOutBuffer; 
      } 
     } while (dwSize > 0); 
    } 

    // Report any errors. 
    if (!bResults) 
     printf("Error %d has occurred.\n", GetLastError()); 

    // Close any open handles. 
    if (hRequest) WinHttpCloseHandle(hRequest); 
    if (hConnect) WinHttpCloseHandle(hConnect); 
    if (hSession) WinHttpCloseHandle(hSession); 

    return response; 

} 

schließlich das ist, was ich als Antwort in WireShark:

Hypertext Transfer Protocol 
    HTTP/1.1 200 OK\r\n 
    Request Version: HTTP/1.1 
    Status Code: 200

Kann jemand mir helfen, Plätzchen bitte hinzuzufügen? Dank

Cookies sollten automatisch funktionieren, wenn Sie alle Ihre Anfragen innerhalb derselben Sitzung stellen. Rufen Sie WinHttpOpen einmal auf, verwenden Sie das Session-Handle in allen Anfragen. Es ist die Sitzung, die das Cookie-Glas verwaltet.
