如何发送授权请求

Question

我以编程方式向远程服务器发送请求：

string xml = "SomeXML Data";

string url = @"http://someserver.com";

WebRequest request = WebRequest.Create(url);
request.Method = "Post";
request.ContentType = "text/xml";

//The encoding might have to be chaged based on requirement
UTF8Encoding encoder = new UTF8Encoding();
byte[] data = encoder.GetBytes(xml); //postbody is plain string of xml
request.ContentLength = data.Length;
Stream reqStream = request.GetRequestStream();
reqStream.Write(data, 0, data.Length);
reqStream.Close();
System.Net.WebResponse response = request.GetResponse();
System.IO.StreamReader reader = new System.IO.StreamReader(response.GetResponseStream());
string str = reader.ReadToEnd();

但此代码会引发错误：

远程服务器返回错误：(401) 未经授权。

当 IE 询问我时，我知道要授权的用户/通行证。

谁能帮我如何发送授权请求？ 谢谢！

Answer 1

webClient.Credentials = new NetworkCredential("Login", "Password");

Answer 2

服务器似乎使用 Windows 身份验证 - 尽管我只是猜测。如果是这样，请添加此行：

   request.Credentials = CredentialCache.DefaultCredentials;

Answer 3

看起来服务器正在使用 Windows 集成安全性？

尝试这样的事情

WebRequest req = WebRequest.Create(tokenUri);
req.AuthenticationLevel = System.Net.Security.AuthenticationLevel.MutualAuthRequested;
req.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
