We can find details about Proxy Authentication and Sever Authentication methed in MSDN.
Just search for the keyword "INTERNET_OPTION_USERNAME".
Here I give a very simple example. It works in my project.
CString GeHttptFile(const char *url)
{
CString szContent;
char strProxyList[MAX_PATH], strUsername[64], strPassword[64];
//in this case "proxya" is the proxy server name, "8080" is its port
strcpy(strProxyList, "proxya:8080");
strcpy(strUsername, "myusername");
strcpy(strPassword, "mypassword");
DWORD dwServiceType = AFX_INET_SERVICE_HTTP;
CString szServer, szObject;
INTERNET_PORT nPort;
AfxParseURL(url, dwServiceType, szServer, szObject, nPort);
CInternetSession mysession;
CHttpConnection* pConnection;
CHttpFile* pHttpFile;
pConnection = mysession.GetHttpConnection(szServer,
INTERNET_FLAG_KEEP_CONNECTION,
INTERNET_INVALID_PORT_NUMBER,
NULL, NULL);
pHttpFile = pConnection->OpenRequest("GET", szObject,
NULL, 0, NULL, NULL,
INTERNET_FLAG_KEEP_CONNECTION);
//here for proxy
INTERNET_PROXY_INFO proxyinfo;
proxyinfo.dwAccessType = INTERNET_OPEN_TYPE_PROXY;
proxyinfo.lpszProxy = strProxyList;
proxyinfo.lpszProxyBypass = NULL;
mysession.SetOption(INTERNET_OPTION_PROXY, (LPVOID)&proxyinfo, sizeof(INTERNET_PROXY_INFO));
pHttpFile->SetOption(INTERNET_OPTION_PROXY_USERNAME, strUsername, strlen(strUsername)+1);
pHttpFile->SetOption(INTERNET_OPTION_PROXY_PASSWORD, strPassword, strlen(strPassword)+1);
pHttpFile->SendRequest(NULL);
DWORD nFileSize = pHttpFile->GetLength();
LPSTR rbuf = szContent.GetBuffer(nFileSize);
UINT uBytesRead = pHttpFile->Read(rbuf, nFileSize);
szContent.ReleaseBuffer();
pHttpFile->Close();
delete pHttpFile;
pConnection->Close();
delete pConnection;
mysession.Close();
return szContent;
}
