Я хотел бы знать, как я могу загрузить исходный HTML-код веб-сайта в строку без использования LibCurl. Я искал в Интернете примеры использования Wininet.

Ниже приведен пример кода, который я использовал для Wininet. Как бы я сделал то же самое с помощью Winsock?

    #include "stdafx.h"
#include <windows.h>
#include <wininet.h>
#include <iostream>
#include <string>
#include <stdio.h>
#include <stdlib.h>
using namespace std;

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

int main()
{
    HINTERNET hInternet = InternetOpenA("InetURL/1.0", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);

    HINTERNET hConnection = InternetConnectA(hInternet, "google.com", 80, " ", " ", INTERNET_SERVICE_HTTP, 0, 0);

    HINTERNET hData = HttpOpenRequestA(hConnection, "GET", "/", NULL, NULL, NULL, INTERNET_FLAG_KEEP_CONNECTION, 0);

    char buf[2048];
    string lol;
    HttpSendRequestA(hData, NULL, 0, NULL, 0);

    DWORD bytesRead = 0;
    DWORD totalBytesRead = 0;
    // http://msdn.microsoft.com/en-us/library/aa385103(VS.85).aspx
    // To ensure all data is retrieved, an application must continue to call the
    // InternetReadFile function until the function returns TRUE and the
    // lpdwNumberOfBytesRead parameter equals zero. 
    while (InternetReadFile(hData, buf, 2000, &bytesRead) && bytesRead != 0)
    {
        buf[bytesRead] = 0; // insert the null terminator.

        puts(buf);          // print it to the screen.
        lol = lol + buf;

        printf("%d bytes read\n", bytesRead);

        totalBytesRead += bytesRead;
    }

    printf("\n\n END -- %d bytes read\n", bytesRead);
    printf("\n\n END -- %d TOTAL bytes read\n", totalBytesRead);

    InternetCloseHandle(hData);
    InternetCloseHandle(hConnection);
    InternetCloseHandle(hInternet);

    cout << "\nThe beginning." << endl << endl << endl;

    cout << lol << endl;


    system("PAUSE");
}

Этот пример WinSock работает для сайтов без дополнительных путей. Как мне получить HTML-код страницы, подобной этой: (www.website.com/page)

    #include "stdafx.h"
#include <iostream>
#include <winsock2.h>
#include <string>
#include <fstream>
using namespace std;


string get_source()
{
    WSADATA WSAData;
    WSAStartup(MAKEWORD(2, 0), &WSAData);

    SOCKET sock;
    SOCKADDR_IN sin;

    char buffer[1024];

    ////////////////This is portion that is confusing me//////////////////////////////////////////////////

    WSACleanup();

    return source;
}

    fout << get_source(); // the string url doesnt matter
    fout.close();
