C++ Helper Functions for Output to File/HTTP GET/HTTP POST

Here's the combination of helper functions I'm using to send data to either files or an HTTP server, variable filename, server, URI path, etc...

int httpSendPost(string server, string path, string data)
{
 char* buf = &data[0];
 string url = path + data; //combine path + data
 wstring url1 = wstring(url.begin(), url.end()); // turn url into a wide string
 wstring server1 = wstring(server.begin(), server.end()); // turn server into wide string
 GetLastError();
 HINTERNET hInternet, hConnect, hRequest;
 hInternet = InternetOpen(TEXT("My UserAgent"), INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, NULL);
 hConnect = InternetConnect(hInternet, server1.c_str(), INTERNET_DEFAULT_HTTP_PORT, 0, 0, INTERNET_SERVICE_HTTP, 0, 0);
 hRequest = HttpOpenRequest(hConnect, TEXT("POST"), url1.c_str(), 0, 0, 0, INTERNET_FLAG_RELOAD, 0);
 if (hRequest == NULL)
  cout << "HttpOpenRequest error code: " << GetLastError() << endl;
 if (!HttpSendRequest(hRequest, 0, 0, buf, data.length()))
  cout << "HttpSendRequest error code: " << GetLastError() << endl;
 InternetCloseHandle(hInternet);
 InternetCloseHandle(hConnect);
 InternetCloseHandle(hRequest);
 return 0;
}

int httpSendGet(string server, string path, string data)
{
 string url = path + data; //combine path + data
 wstring url1 = wstring(url.begin(), url.end()); // turn url into a wide string
 wstring server1 = wstring(server.begin(), server.end()); // turn server into wide string
 GetLastError();
 HINTERNET hInternet, hConnect, hRequest;
 hInternet = InternetOpen(TEXT("My UserAgent"), INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, NULL);
 hConnect = InternetConnect(hInternet, server1.c_str(), INTERNET_DEFAULT_HTTP_PORT, 0, 0, INTERNET_SERVICE_HTTP, 0, 0);
 hRequest = HttpOpenRequest(hConnect, TEXT("GET"), url1.c_str(), 0, 0, 0, INTERNET_FLAG_RELOAD, 0);
 if (hRequest == NULL)
  cout << "HttpOpenRequest error code: " << GetLastError() << endl;
 if (!HttpSendRequest(hRequest, 0, 0, NULL, NULL))
  cout << "HttpSendRequest error code: " << GetLastError() << endl;
 InternetCloseHandle(hInternet);
 InternetCloseHandle(hConnect);
 InternetCloseHandle(hRequest);
 return 0;
}

int toTempFile(string fileName, string toFile)
{
 wstring fileName1 = wstring(fileName.begin(), fileName.end());

 wstring path;
 wchar_t wchPath[MAX_PATH];
 if (GetTempPathW(MAX_PATH, wchPath))
  path = wchPath;
 path = path.append(fileName1.c_str());
 ofstream out(path, ios::app);
 out << toFile << endl;
 out.close();
 return 0;
}
