验证HttpWebRequest时出现问题

远程服务器返回错误:(401)Unauthorized.

这是我的代码:

ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;
NetworkCredential networkCredential = new NetworkCredential(username, password);
WebRequest http = HttpWebRequest.Create(new Uri(url));
http.Timeout = timeout;
http.PreAuthenticate = true;
http.Credentials = networkCredential;
try
{
    HttpWebResponse ws = (HttpWebResponse)http.GetResponse();
    Stream str = ws.GetResponseStream();
}
catch (WebException ex)
{
    Console.WriteLine(ex.Message);
}

和我尝试用另一种方式设置授权:

string credentials = String.Format("{0}:{1}", username, password);
byte[] bytes = Encoding.ASCII.GetBytes(credentials);
string base64 = Convert.ToBase64String(bytes);
string authorization = String.Concat("Basic ", base64);
http.Headers.Add("Authorization", authorization);

NetworkCredential 401 unauthorized HttpWebRequest

如果您在公司网络上，它可能是呈现401的代理服务器，而不是您期望的终端web服务器。记住这一点。

尝试将授权从基本设置为NTLM

如果没有关于您正在连接的应用程序和网络配置的大量信息，那么它只是猜测工作
