Simulate ie login to a website that requires (Windows identity) Authentication

User Authentication

Httpwebrequest can be implemented.

The simplest method is to put the user name and password in the URL.

For example: http: // username: password@www.abc.com/

A complicated method is to add authorization in the request header. Format: Basic + base64 (username: password)

 

For example:

 

Public static string senddatabyget (string URL, string postdatastr, ref cookiecontainer cookie)
{
Try
{
String url = URL + (postdatastr = ""? "":"? ") + Postdatastr;
Httpwebrequest request = (httpwebrequest) webrequest. Create (URL );
// If (cookie. Count = 0)
//{
// Request. cookiecontainer = new cookiecontainer ();
// Cookie = request. cookiecontainer;
//}
// Else
//{
Request. cookiecontainer = cookie;
//}
Request. keepalive = true;
Request. headers. Add ("Authorization", "Basic ym9uc29uomjvbnnvbg = ");
Request. cookiecontainer = cookie;
Request. Credentials = credentialcache. defaultcredentials;

Request. method = "get ";
// Request. Timeout = 1000*300;
Request. contenttype = "text/html; charset = gb2312 ";
Request. useragent = "Mozilla/4.0 (compatible; MSIE 7.0;   Windows   NT 5.1; Trident/4.0; myie2 0.3; Mogi/1;   . Net   CLR 2.0.50727;. net   CLR 3.0.04506.648;. Net CLR 3.5.21022;. Net CLR 3.0.20.6.2152;. Net CLR 3.5.30729 )";

Httpwebresponse response = (httpwebresponse) request. getresponse ();
Stream myresponsestream = response. getresponsestream ();
Streamreader   Mystreamreader = new streamreader (myresponsestream, encoding. getencoding ("gb2312 "));
String retstring = mystreamreader. readtoend ();
Mystreamreader. Close ();
Myresponsestream. Close ();

Return retstring;
}
Catch (exception ex)
{
Return "submission error:" + ex. message;
}
}
