Question

有没有办法通过WebSocket4Net进行Http身份验证？我想将凭据传递给我的客户。这就是我的代码：

public bool Connect(string uri, ICredentials credentials = null)
{
  if (this.ws == null)
  {
    try
    {
      ////this.ws = new WebSocket(uri, string.Empty, WebSocketVersion.None, null, );
      this.ws = new WebSocket(uri);
      this.ws.Opened += this.OnWebSocketOpen;
      this.ws.Closed += this.OnWebSocketClose;
      this.ws.Error += this.OnWebSocketFail;
      this.ws.MessageReceived += this.OnWebSocketMessage;

      try
      {
        this.ws.Open();
        return true;
      }
      catch (Exception ex)
      {
        Log.Error("Open web socket failed", ex);
        this.ws = null;
      }
    }
    catch (Exception exception)
    {
      throw new CanNotConnectToDeviceException(new Uri(uri, UriKind.Relative), exception);
    }
  }

  return false;
}

我不确定我清楚地理解你的问题，但我仍然会尽力帮助。

您是说您正在开发Web服务，还需要“基本HTTP身份验证”吗？

如果您正在服务器端，并且需要身份验证，则可以先响应HTTP 401。

大多数浏览器会在收到HTTP 401时通知用户。

如果您正在进行客户端，并且想要自动发送身份验证，

您可以参考the issue of WebSocket4Net。

请注意，基本HTTP身份验证是PLAIN TEXT。

感谢J.C的链接。我用它来创建一个小帮助类。

public class HttpHelper : IHttpHelper
{
      public KeyValuePair<string, string>
             CreateAuthorizationHeader(ICredentials credentials)
      {
          NetworkCredential networkCredential = 
              credentials.GetCredential(null, null);

          string userName = networkCredential.UserName;
          string userPassword = networkCredential.Password;

          string authInfo = userName + ":" + userPassword;
          authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));

          return new KeyValuePair<string, string>("Authorization", "Basic " + authInfo);
     }
}
