[C\C++] WinSoket (http\GET\POST)

[Крайслер]

вполне работоспособный кусок из моего стародавнего проекта.
Вырезал все навесные методы, оставив только основную(очень упрощенную) рабочию часть.
В коде умышленно допущен "недочет"(не влияющий на общию работоспособность), дабы был)))

Использовать так:

php:

switch ($_POST['MESSAGE']) {
    case 'USER':
        echo 'Крайслер';
        break;
}

С++:

cWinSoket* m_pSoket = new cWinSoket("uengine.loc");
    if (m_pSoket->Connect()) {
        
        if (m_pSoket->Send(ePOST , "/TestPost.php", "MESSAGE=USER")) {

            char buffer[1024] = { '\0' };
            if (m_pSoket->Recv(buffer, 1024))
            {
                printf_s("All answer:\n%s\n\n",buffer);

                std::string szBody = m_pSoket->getBody(buffer);

                printf_s("Result answer:\n%s\n", szBody.data());
            }
        }
    }

    delete m_pSoket;

Результат:
