GetHttpConnection

[ami]

Hello,

I have the following code

...
CString GE_URL ( "www.google.com");
CString GE_File( "test.txt" );
DisplayHttpPage( GE_URL, GE_File );
...


static void DisplayHttpPage(LPCTSTR pszServerName, LPCTSTR pszFileName)
{
CInternetSession session(_T("Ami's Session"));
session.SetOption(INTERNET_OPTION_CONNECT_TIMEOUT, 1000);
session.SetOption(INTERNET_OPTION_CONNECT_RETRIES, 3);

try {
CString strServerName;
INTERNET_PORT nPort = 80;
DWORD dwRet = 0;
CString username = "...";
CString password = "...";


CHttpConnection* pServer = session.GetHttpConnection(pszServerName, 1, nPort, username, password);
CHttpFile* pFile = pServer->OpenRequest(_T("GET"),pszServerName,NULL,1,NULL,NULL,INTERNET_FLAG_KEEP_CONNECTION);
pFile->SendRequest(); // throws "URL not found" exception here...
pFile->QueryInfoStatusCode(dwRet);

cout << "dwRet = [" << dwRet << "]\n";

if (dwRet == HTTP_STATUS_OK)
{
CHAR szBuff[1024];
while (pFile->Read(szBuff, 1024) > 0)
{
std::cout << "szBuff = [" << szBuff << "]\n";
}
}
delete pFile;
delete pServer;
}
catch (CInternetException* pEx) { //catch errors from WinInet
TCHAR pszError[64];
pEx->GetErrorMessage(pszError, 64);
std::cout << "Error : [" << pszError << "]\n";
}
session.Close();
}

I am always getting dwRet to be 502.

Can someone please advise why this is the case and what this error means and how to resolve it ?

Many thanks.

HTTP_STATUS_BAD_GATEWAY

according to google, ^^^^^^^ is your error code (502). How to fix that, I do not know.

Thanks for the reply Jonnin.

Does the code look ok to you ?

Many thanks for your help.

The code looks legal, but its using API calls that I do not have experience with (I use low level UDP code for what networking we do, or just bytes directly sent to the radios sometimes). I have no idea beyond what google had to say, which implies the code is ok but the parameters are wrong (but thats just a guess!).
