Http POST c++ [help]

[m0mathur]

Good afternoon,

I have issues with this i am new to winsock. so i was learning to use winsock for http POST request

Compiles correctly, but doesnt connect i get the error "Connection Failure" what do you think can be wrong

my code goes like this:

#define WIN32_LEAN_AND_MEAN

#include "stdafx.h"
#include <cstdio>
#include <cstdlib>
#include <Winsock2.h>
#include <WS2tcpip.h>
#include <windows.h>

#pragma comment (lib,"ws2_32")

int _tmain(int argc, _TCHAR* argv[])
	{
	  WSADATA wsaData;
	  int iResult = WSAStartup(MAKEWORD(2,2),&wsaData);
	  SOCKET m_socket;
	  m_socket = socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
	  if(m_socket==INVALID_SOCKET)
		{
		printf("Invalid Socket :WSAGetLastError()");
			}
	sockaddr_in clientService;
	clientService.sin_family = AF_INET;
	clientService.sin_addr.s_addr = inet_addr("127.0.0.1");
	clientService.sin_port = htons(5209);
	LPHOSTENT host = gethostbyname("72.144.89.32");

	if(connect(m_socket,(SOCKADDR*)&clientService,sizeof(clientService))==SOCKET_ERROR)
	{
	  printf("Connection Failure");
	  WSACleanup();
	  return 1;
	}
	
	char buffer[2048];
	
	strcpy(buffer,"POST /dbarea.php HTTP/1.1\n");
	strcat(buffer,"Content - Type:application/x-www-form-urlencoded\n");
	strcat(buffer,"Host: localost\n");
	strcat(buffer,"content-Length:32\n");
	strcat(buffer,"\n");
	strcat(buffer,"username=emeka1&password=laikan112");
	//int n = write(SOCKADDR*,buffer,strlen(buffer));
	
	printf("Data Sent Successfully..");

	return 0;

		}

Is that port (5209) open and excepting connections on the host you are trying to connect to, i.e. your machine?

[m0mathur]

I tried to telnet earlier didn't allow it.
I will check and see If the port appears to be open.

[Computergeek01]

Don't forget about your firewall. If it isn't told to allow inbound traffic on that port then it will block it.

Ok I ran netstat-a, saw some open ports when I changed the port from 5209, to 5357, it showed the "data sent successfully, so I check now with php and see if it transfers the data. Thanks a whole lot geek, you are the best.
