无法使用标头中的Windows集成身份验证凭据创建httpwebrequest [英] Cannot create httpwebrequest with windows integrated authentication credentials in headers

问题描述

我正在尝试在我的C＃desktop
程序中使用Windows集成身份验证从HTTP服务器获取一些网页。我不希望用户再次输入用户名，密码或域名。这是我用来尝试测试获取HTTP GET中信息的代码的代码：

  //准备请求 
 
 HttpWebRequest webrequest = 
 
（HttpWebRequest）WebRequest.Create（" http://test.local/wia" ）; 
 
 webrequest.Method = WebRequestMethods.Http.Get; 
 
 webrequest.Accept = " text / plain" ; 
 
 webrequest.KeepAlive =  false ; 
 
 webrequest.AllowAutoRedirect =  true ; 
 
 webrequest.AllowWriteStreamBuffering =  true ; 
 
 webrequest.KeepAlive =  true ; 
 
 webrequest.ContentLength = 0; 
 
 webrequest.ProtocolVersion =  new 版本（" 1.1" ） ; 
 
 
 
 CredentialCache cred =  new  CredentialCache（）; 
 
 cred.Add（" http：//test.local.wia" ，8020，"NTLM" ，
 
 CredentialCache.DefaultNetworkCredentials）; 
 
 webrequest.Credentials = cred; 
 
 
 
  //显示请求 
 
 System.Diagnostics.Debug.WriteLine （"请求信息开始"）; 
 
 System.Diagnostics.Debug.WriteLine（" URI ="  + 
 
 webrequest.RequestUri） ; 
 
 System.Diagnostics.Debug.WriteLine（" Method ="  + 
 
 webrequest.Method） ; 
 
 System.Diagnostics.Debug.WriteLine（" Request Info END" ）; 
 
 System.Diagnostics.Debug.WriteLine（" Request Headers START" ）; 
 
 System.Diagnostics.Debug.WriteLine（webrequest.Headers）; 
 
 System.Diagnostics.Debug.WriteLine（" Request Headers END" ）; 
 
 
 
 

解决方案

除非服务器请求，否则不会发送身份验证它。所以你看到它是在以后的请求中发送的吗？参见例如 http://blogs.msdn.com/feroze_daud/archive/2004/07/12/ 180856.aspx

Hi,
I am trying to use Windows Integrated Authentication in my C# desktop
program to get some web pages from a HTTP server.  I don't want the user to
have to type in their username, password or domain again.  This is the code I
have been using to try and test getting the credentials into the HTTP GET
message:

           // prepare the request

            HttpWebRequest webrequest = 

(HttpWebRequest)WebRequest.Create("http://test.local/wia");

            webrequest.Method = WebRequestMethods.Http.Get;

            webrequest.Accept = "text/plain";

            webrequest.KeepAlive = false;

            webrequest.AllowAutoRedirect = true;

            webrequest.AllowWriteStreamBuffering = true;

            webrequest.KeepAlive = true;

            webrequest.ContentLength = 0;

            webrequest.ProtocolVersion = new Version("1.1");



            CredentialCache cred = new CredentialCache();

            cred.Add("http://test.local.wia", 8020, "NTLM", 

CredentialCache.DefaultNetworkCredentials);

            webrequest.Credentials = cred;



            // display the request

            System.Diagnostics.Debug.WriteLine("Request Info START");

            System.Diagnostics.Debug.WriteLine("URI = " + 

webrequest.RequestUri);

            System.Diagnostics.Debug.WriteLine("Method = " + 

webrequest.Method);

            System.Diagnostics.Debug.WriteLine("Request Info END");

            System.Diagnostics.Debug.WriteLine("Request Headers START");

            System.Diagnostics.Debug.WriteLine(webrequest.Headers);

            System.Diagnostics.Debug.WriteLine("Request Headers END");

解决方案

Authentication won't be sent unless the server requests it.  So do you see it being sent on later requests?  See e.g. http://blogs.msdn.com/feroze_daud/archive/2004/07/12/180856.aspx
