HttpSendRequestEx Error

[maxixi]

Hi,

I use async mode to (cookie) logon a site and download resources.
Here is my code

// TestWinINet.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"

#include <windows.h>
#include <wininet.h>
#include <iostream.h>

void CALLBACK Callback(
HINTERNET hInternet,
DWORD_PTR dwContext,
DWORD dwInternetStatus,
LPVOID lpvStatusInformation,
DWORD dwStatusInformationLength
)
{
switch(dwContext) {
case 1:
cout << "Context 1 ";
switch (dwInternetStatus) {
case INTERNET_STATUS_HANDLE_CREATED:
cout << "INTERNET_STATUS_HANDLE_CREATED" << endl;
{
LPINTERNET_ASYNC_RESULT ret = (LPINTERNET_ASYNC_RESULT)
lpvStatusInformation;
HINTERNET m_hConnection = (HINTERNET)ret->dwResult;
HINTERNET m_hRequest = HttpOpenRequest(
m_hConnection, "POST", "/rss/login_main.rs",
NULL, NULL, NULL, INTERNET_FLAG_NO_CACHE_WRITE, 2);
}
break;
default:
break;
}
break;
case 2:
cout << "Context 2 ";
switch (dwInternetStatus) {
case INTERNET_STATUS_HANDLE_CREATED:
cout << "INTERNET_STATUS_HANDLE_CREATED" << endl;
{
LPINTERNET_ASYNC_RESULT ret = (LPINTERNET_ASYNC_RESULT)
lpvStatusInformation;
HINTERNET m_hRequest = (HINTERNET)ret->dwResult;

char pos[] = "uname=greenxiar&passwd=123456";
char hed[] = "Content-Type: application/x-www-form-urlencoded\r\n";

INTERNET_BUFFERS BufferIn;
memset(&BufferIn, 0, sizeof(BufferIn));
BufferIn.dwStructSize = sizeof(BufferIn);

BufferIn.lpvBuffer = NULL;
BufferIn.dwBufferTotal = strlen(pos);

BufferIn.lpcszHeader = hed;
BufferIn.dwHeadersLength = BufferIn.dwHeadersTotal = strlen(hed);

if (!HttpSendRequestEx(m_hRequest, &BufferIn, NULL, HSR_SYNC, 3))
{ cout << GetLastError() << endl; }
DWORD wd;
InternetWriteFile(m_hRequest, (void*) pos, strlen(pos), &wd);
}
break;
default:
break;
}
break;
case 3:
cout << "Context 3 ";
switch (dwInternetStatus) {
case INTERNET_STATUS_HANDLE_CREATED:
cout << "INTERNET_STATUS_HANDLE_CREATED" << endl;
{
LPINTERNET_ASYNC_RESULT ret = (LPINTERNET_ASYNC_RESULT)
lpvStatusInformation;
HINTERNET m_hRequest = (HINTERNET)ret->dwResult;
}
break;
default:
break;
}
}
}

int main(int argc, char* argv[])
{
HINTERNET m_hSession;
m_hSession = InternetOpen(NULL, INTERNET_OPEN_TYPE_PRECONFIG, 0, 0,
INTERNET_FLAG_ASYNC);
InternetSetStatusCallback(m_hSession, Callback);

HINTERNET m_hConnection;
m_hConnection = InternetConnect(m_hSession, "www.rongshuxia.com", 80,
NULL, NULL, INTERNET_SERVICE_HTTP, INTERNET_ASYN_FLAG, 1);

InternetCloseHandle(m_hSession);
return 0;
}

But I always failed when call HttpSendRequestEx and
received error 12019. What's wrong with my code?

Take a look at the following article and see if that code works.
