.net - HttpListener 认证

Question

我目前正在使用 .NET 中的代理，该代理必须具有使用基本身份验证的选项。我已经广泛地寻找示例，但似乎无法让它发挥作用。

我正在基于布尔值设置 AuthenticationSchemes，然后我正在设置“WWW-Authenticate”标头以及“Authorization”标头。不幸的是，我总是收到 401 响应。代理应该接受 admin/admin 作为用户名和密码，它不必非常安全。

这是我当前的代码：

public void StartProxy() {
            string urlBase = $"http://127.0.0.1:{port}/";
            if (isStarted) {
                return;
            }

            if(httpListener == null) {
                httpListener = new HttpListener();
            }

            httpListener.Prefixes.Add(urlBase);

            if (basicAccessAuth) {
                httpListener.AuthenticationSchemes = AuthenticationSchemes.Basic;
            }
            isStarted = true;
            httpListener.Start();

            IAsyncResult result = httpListener.BeginGetContext(new AsyncCallback(WebRequestCallback), httpListener);
        }

        private void WebRequestCallback(IAsyncResult result) {
            if (httpListener == null) {
                return;
            }

            HttpListenerContext context = httpListener.EndGetContext(result);

            httpListener.BeginGetContext(new AsyncCallback(WebRequestCallback), httpListener);

            if (ReceiveWebRequest != null) {
                ReceiveWebRequest(context);
            }
            ProcessRequest(context);

        }

private void ProcessRequest(HttpListenerContext Context) {
            HttpListenerRequest Request = Context.Request;
            HttpListenerResponse Response = Context.Response;

            NameValueCollection nvCol = new NameValueCollection();
            nvCol.Add("Authorization", "admin:admin");

            if (basicAccessAuth) {
                Request.Headers.Add(nvCol);
                Response.Headers.Add("WWW-Authenticate");

                HttpListenerBasicIdentity identity = (HttpListenerBasicIdentity)Context.User.Identity;
                MessageBox.Show(identity.Name);
            }
            StringBuilder sb = new StringBuilder();

            if (Request.UrlReferrer != null) {
                sb.AppendLine("Referer: " + Request.UrlReferrer);

            }

            if (Request.UserAgent != null) {
                sb.AppendLine("User-Agent: " + Request.UserAgent);
            }

            for (int i = 0; i < Request.Headers.Count; i++) {
                sb.AppendLine(Request.Headers.Keys[i] + ":" + " " + Request.Headers[i]);
            }

            sb.AppendLine();

            //will this fail if headers are added/removed ?
            string Output = getHtmlForRequest(Request.Headers[5]);

            sb.AppendLine(Output);

            Task.Run(() => {
                LogModel log = new LogModel(sb.ToString());
                addMessageToLogDelegate(log);
            });

            byte[] bOutput = System.Text.Encoding.UTF8.GetBytes(Output);

            Response.ContentType = "text/html";

            Response.ContentLength64 = bOutput.Length;

            Stream OutputStream = Response.OutputStream;

            OutputStream.Write(bOutput, 0, bOutput.Length);

            OutputStream.Close();

        }

如您所见，我在“ProcessRequest”函数中设置了标题，但似乎无法使其正常工作。我做错了什么，我该如何解决？
