visual studio 2015 c++ http get&post - c++

Question

I need help with http get. I use vsc++ 2015. I have my own code, but it seems to be wrong, so I get reply from server in a strange format.
Example : 034a0686bc29ca826dbb2f1ea4dd1879═
so the Source is:
#include "Connection.h"
CConnector g_pConnector;
CConnector::CConnector() {
}
CConnector::~CConnector() {
}
void CConnector::Connect(char* Url, char* Host) { m_Url = Url; m_Host = Host; }
void CConnector::SendPOST(const char* data, std::string &sDestBuffer) { try { char httpUseragent[512]; DWORD szhttpUserAgent = sizeof(httpUseragent); ObtainUserAgentString(0, httpUseragent, &szhttpUserAgent);
CString sMsg = ""; sMsg += /*\r\ncontent-type: application/x-www-form-urlencoded*/"\r\ncontent-type: application/x-www-form-urlencoded"; sMsg += /*\r\ncontent-lenght:
*/"\r\ncontent-lenght: "; sMsg += std::to_string(strlen(data)).c_str(); sMsg += /*\r\nuser-agent: secret_agent\r\n\r\n*/"\r\nuser-agent: secret_agent\r\n\r\n";
HINTERNET internet = InternetOpenA(httpUseragent, INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0); if (internet != NULL) {
HINTERNET connect = InternetConnectA(internet, m_Host, INTERNET_DEFAULT_HTTP_PORT, NULL, NULL, INTERNET_SERVICE_HTTP, 0, 0); if (connect != NULL) {
HINTERNET request = HttpOpenRequestA(connect, /*POST*/"POST", m_Url, /*HTTP/1.1*/"HTTP/1.1", NULL, NULL,

if (request != NULL)
{
int datalen = 0;
if (data != NULL) datalen = strlen(data);
int headerlen = 0;
if (!sMsg.IsEmpty()) headerlen = strlen(sMsg);
HttpSendRequestA(request, sMsg, headerlen, _strdup(data), datalen);
if (request)
{
DWORD dataSize = 0;
DWORD dwBytesRead = 0;
DWORD dwBytesWritten = 0;
char* data = NULL;
do {
char buffer[2000];
InternetReadFile(request, (LPVOID)buffer, _countof(buffer), &dwBytesRead);
char *tempData = new char[dataSize + dwBytesRead];
memcpy(tempData, data, dataSize);
memcpy(tempData + dataSize, buffer, dwBytesRead);
delete[] data;
data = tempData;
dataSize += dwBytesRead;
} while (dwBytesRead);
sDestBuffer = data;
}
InternetCloseHandle(request);
} } InternetCloseHandle(connect); } InternetCloseHandle(internet); } catch (...) {} }
void CConnector::SendGET(const char* data, std::string &sDestBuffer) { try { char httpUseragent[512]; DWORD szhttpUserAgent = sizeof(httpUseragent); ObtainUserAgentString(0, httpUseragent, &szhttpUserAgent);
CString sMsg = ""; CString Url = m_Url; Url += "?"; Url += data;
HINTERNET internet = InternetOpenA(httpUseragent, INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0); if (internet != NULL) {
HINTERNET connect = InternetConnectA(internet, m_Host, INTERNET_DEFAULT_HTTP_PORT, NULL, NULL, INTERNET_SERVICE_HTTP, 0, 0); if (connect != NULL) {
HINTERNET request = HttpOpenRequestA(connect, /*GET*/"GET", Url, /*HTTP/1.1*/"HTTP/1.1", NULL, NULL,

if (request != NULL)
{

if (data != NULL) datalen = strlen(data);
int headerlen = 0;
if (!sMsg.IsEmpty()) headerlen = strlen(sMsg);
HttpSendRequestA(request, sMsg, headerlen, _strdup(data), datalen);
if (request)
{
DWORD dataSize = 0;
DWORD dwBytesRead = 0;
DWORD dwBytesWritten = 0;
char* data = NULL;
do {
char buffer[2000];

memcpy(tempData, data, dataSize);
memcpy(tempData + dataSize, buffer, dwBytesRead);
delete[] data;
data = tempData;
dataSize += dwBytesRead;
} while (dwBytesRead);
sDestBuffer = data;
}
InternetCloseHandle(request);
} } InternetCloseHandle(connect); }
InternetCloseHandle(internet); } catch (...) {} }
and I try getting reply like this
std::string request;
char key[128];
g_pConnector.Connect(script.php?something=139, "sample.com");
g_pConnector.SendGET(key, request);
