How to post a request to an https url

[nilanka_shani]

Hi,

 

I want to post an XMLHTTPRequest to a server for the screen scrapping

purpose. but it always throws an exception . :confused:

{"The download of the specified resource has failed.\r\n" }
  [system.Runtime.InteropServices.COMException]:
{System.Runtime.InteropServices.COMException}
  System.Object: {System.Runtime.InteropServices.COMException}
  _className: null
  _COMPlusExceptionCode: -532459699
  _exceptionMethod: <undefined value>
  _exceptionMethodString: null
  _helpURL: null
  _HResult: -2146697208

This is the code I have written.

 

MSXML.XMLHTTPRequestClass lobjRequest = new XMLHTTPRequestClass();

string lstrNull = null;
object lobjNull =lstrNull;
string lstrBody="";

lobjRequest.open("POST","https://xxxxxxxxxxx, false, lobjNull,
lobjNull);

lobjRequest.setRequestHeader("Content-Type",
"application/x-www-form-urlencoded");
lobjRequest.setRequestHeader("Referer","http://xxxxxxxx");

string lstrRequest="xxxxxxxxxxxxxxxxx";

lobjRequest.send(lstrRequest);
lstrBody = lobjRequest.responseText;

 

The same code works fine when the request is posted to an http url.

 

Is there any solution for this? I tried to use WinHttp. But it also

asks for a client certificate.

 

hope someone will help me. :rolleyes:

Have you tried using the classes under System.Net and it's related namespaces rather than the COM objects? Have a look at the WebClient class or possibly the HttpWebRequest and the HttpWebResponse classes as they should be able to do this.
