WinInet POST über SSL (HTTPS) mit reinem C?

Question

Ich stehe fest, versucht, einen WinInet HTTP POST über SSL mit NUR C zu bekommen. Ich weiß, dass es möglich ist. Jeder gute Beispielcode?

Vielen Dank!

EDIT: der folgende Code scheint OK unter C zu arbeiten ++ WinHTTP verwenden, aber ich brauche WinInet:

TCHAR szTemp[512] = {0}; 
BOOL bRet = FALSE; 
HINTERNET hRequest = NULL; 
HINTERNET hSession = NULL; 
HINTERNET hConnect = NULL; 
CERT_CONTEXT *pCert = {0}; 
HCERTSTORE hCertStore = NULL; 
DWORD dwRet = 0; 
DWORD dwLen = 0; 
DWORD dwFlags = SECURITY_FLAG_IGNORE_CERT_CN_INVALID| 
       SECURITY_FLAG_IGNORE_CERT_DATE_INVALID| 
       SECURITY_FLAG_IGNORE_UNKNOWN_CA; 

CString szUserAgent("Mozilla/4.0 (compatible; MSIE 5.22)"); 

if (m_csServer.GetLength() < 3) { 
    _stprintf_s(szTemp, 512, _T("Server name is invalid or empty")); 
    ::MessageBox(NULL, szTemp, _T("ERROR"), MB_OK); 
    return; 
} 

hSession = WinHttpOpen(szUserAgent, 
    WINHTTP_ACCESS_TYPE_DEFAULT_PROXY, 
    WINHTTP_NO_PROXY_NAME, 
    WINHTTP_NO_PROXY_BYPASS, 0); 

if (NULL == hSession) { 
    dwRet = GetLastError(); 
    _stprintf_s(szTemp, 512, _T("WinHttpOpen Fails - err: 0x%x"), dwRet); 
    ::MessageBox(NULL, szTemp, _T("ERROR"), MB_OK); 
    return; 
} 

hConnect = WinHttpConnect(hSession, 
    m_csServer, 
    INTERNET_DEFAULT_HTTPS_PORT, 
    0); 

if (NULL == hConnect) { 
    dwRet = GetLastError(); 
    _stprintf_s(szTemp, 512, _T("WinHttpConnect Fails - err: 0x%x"), dwRet); 
    ::MessageBox(NULL, szTemp, _T("ERROR"), MB_OK); 
    WinHttpCloseHandle(hSession); 
    return;

     OutputDebugString(_T("X509_ASN_ENCODING")); 
    } 
    if (pCert->dwCertEncodingType & PKCS_7_ASN_ENCODING) { 
     OutputDebugString(_T("PKCS_7_ASN_ENCODING")); 
    } 

    _stprintf_s(szTemp, 512, _T("encoded_size: %ld"), pCert->cbCertEncoded); 
    OutputDebugString(szTemp); 

    hCertStore = CertOpenStore(CERT_STORE_PROV_SYSTEM, 0, 0, CERT_STORE_OPEN_EXISTING_FLAG | CERT_SYSTEM_STORE_LOCAL_MACHINE, L"Root"); 

    bRet = CertAddCertificateContextToStore(

WinHttpCloseHandle(hRequest); 
WinHttpCloseHandle(hConnect); 
WinHttpCloseHandle(hSession);
