c# - NetworkCredential 401 未经授权的 HttpWebRequest

Question

验证 HttpWebRequest 时遇到问题

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);
}

我试图以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);

但这也无济于事。

如果您在公司网络上，它可能是呈现 401 的代理服务器，而不是您期望的最终 Web 服务器。记在脑子里。

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，它只是猜测工作
