c++ - 在 Windows Server 2008 rc2 上使用 https 进行 winhttpsendrequest POST

Question

我正在编写一个 Visual C++ 应用程序，该应用程序应该将 http post 消息发送到 https 端点(https 服务器的证书是自签名的)。有 2 组客户端，一组在 Windows 7 电脑上，另一组在 Windows Server 2008 rc2 上。使用 mmc 控制台/管理单元(在两个电脑组上)导入服务器的自签名证书后，Windows 7 电脑可以毫无错误地建立连接，但在 Windows Server 2008 rc2 计算机上，winhttpsendrequest 始终返回错误 12030( ) 称呼。有什么想法如何解决这个问题吗？任何帮助/提示将不胜感激。提前致谢。我的代码如下。

  DWORD dwSize = 0;
  DWORD dwDownloaded = 0;
  LPSTR pszOutBuffer;
  BOOL  bResults = FALSE;
  HINTERNET  hSession = NULL, 
         hConnect = NULL,
         hRequest = NULL;

 hSession = WinHttpOpen( userAgent,  
                      WINHTTP_ACCESS_TYPE_NO_PROXY,
                      WINHTTP_NO_PROXY_NAME, 
                      WINHTTP_NO_PROXY_BYPASS, 0 );


 if( hSession ){
    hConnect = WinHttpConnect( hSession, hostname, port, 0 );

    if( hConnect ){
       hRequest = WinHttpOpenRequest( hConnect, L"POST", urlPath,
                               NULL, WINHTTP_NO_REFERER, 
                               WINHTTP_DEFAULT_ACCEPT_TYPES, 
                               WINHTTP_FLAG_REFRESH|WINHTTP_FLAG_SECURE      );

if(hRequest){

    AutoProxyOptions.dwFlags = WINHTTP_AUTOPROXY_AUTO_DETECT;

    AutoProxyOptions.dwAutoDetectFlags = WINHTTP_AUTO_DETECT_TYPE_DHCP|WINHTTP_AUTO_DETECT_TYPE_DNS_A;

    AutoProxyOptions.fAutoLogonIfChallenged = TRUE;

    if( WinHttpGetProxyForUrl(  hSession, 
                                fullURL,
                                &AutoProxyOptions,
                                &ProxyInfo))
    {
        printf("proxy info\n");
        printf("access type: %ld\n",ProxyInfo.dwAccessType);
        printf("list: %s\n",ProxyInfo.lpszProxy);
        printf("bypass list: %s\n",ProxyInfo.lpszProxyBypass);

        if( !WinHttpSetOption(  hRequest, 
                                WINHTTP_OPTION_PROXY,
                                &ProxyInfo,
                                cbProxyInfoSize ) )
        {
            printf("Proxy detection logic failed\n");
            goto Exit;
        }
    }
    else
    {
        printf("WinHttpGetProxyForUrl() returned [%d].. no proxy is used?\n", GetLastError());
    }

    bResults = WinHttpSendRequest(hRequest, L"Content-Type:application/x-www-form-urlencoded", 0, (LPVOID)postRequest, data_len, data_len, 0);
 if ( bResults != TRUE) {
    wprintf(L"WinHttpSendRequest failed (%d)\n", GetLastError());
 }
 else
 {
     //all good
    bResults = WinHttpReceiveResponse( hRequest, NULL );

  if( bResults )
  {
    do 
    {
     dwSize = 0;
     if( !WinHttpQueryDataAvailable( hRequest, &dwSize ) )
      printf( "Error %u in WinHttpQueryDataAvailable.\n",  GetLastError());

    pszOutBuffer = new char[dwSize+1];
    if( !pszOutBuffer )
    {
      printf( "Out of memory\n" );
      dwSize=0;
    }
    else
    {
     ZeroMemory( pszOutBuffer, dwSize+1 );

     if( !WinHttpReadData( hRequest, (LPVOID)pszOutBuffer, dwSize, &dwDownloaded ) )
      printf( "Error %u in WinHttpReadData.\n", GetLastError( ) );
    else{
      printf( "From server [");
      printf( "%s", pszOutBuffer );
      printf("]\n");
    }
    delete [] pszOutBuffer;
  }
} while( dwSize > 0 );
  }
 }
}
  else
    {

    }
   }
  }

Answer 1

12030是这样的:

ERROR_INTERNET_CONNECTION_ABORTED
12030
The connection with the server has been terminated.

这看起来可能不仅仅是身份验证或证书错误。

您是否尝试检查服务器日志以了解它如何处理连接？使用 Fiddler 观察流量？

要排除身份验证步骤的问题，请尝试传递一些讨论的 SECURITY_FLAG_IGNORE_CERT_* 标志 here .

此外，请考虑使用WinInet APIs而不是 WinHTTP。使用前者执行某些操作更容易一些。
