HTTP Read w/ Authentication
-
I used the following code to download the source of an HTML page:
... try { // _url is a private variable which contains the URL to download HttpWebRequest _request = (HttpWebRequest)WebRequest.Create(_url); if (_useProxy) { WebProxy _proxy = new WebProxy(_proxyHost + ":" + _proxyPort.ToString()); _request.Proxy = _proxy; } HttpWebResponse _response = (HttpWebResponse)_request.GetResponse(); if (_response.StatusCode == HttpStatusCode.OK) { Stream _stream = _response.GetResponseStream(); StreamReader _streamReader = new StreamReader(_stream, Encoding.UTF8); MessageBox.Show(_streamReader.ReadToEnd().Trim()); } catch (WebException we) { // HTTP response was not "OK", handle HTTP error } catch (Exception e) { // Handle exception } ...My question is, what if the page I need to access requires authentication. In other words, when browsing normally, with a web browser client, a dialog pops up asking for my username and password. I have the access information, but I want the preceding code to be able to send that authentication information along and get the code without any user intervention. Any ideas? -

HttpWebRequest.Credentialsproperty. You can set this to either an instance ofNetworkCredentialorCredentialCache. See the help under these two classes. If your using Windows authentication (typically only in a corproate intranet scenario) this works to provide the credentials the current use is logged in with:request.Credentials = System.Net.CredentialCache.DefaultCredentials;Burt Harris
