<h1>Bad Request (Invalid Hostname)</h1>

我怎么能解决这个问题？

编辑：
这是我的代码

public class Server
{
    private HttpListener Listener;
    private Log Log;
 
    public int Port = 1555;
 
    public Server(Log _log)
    {
        Log = _log;
    }
 
    public void Start()
    {
        Listener = new HttpListener();
        Listener.Prefixes.Add(string.Format("http://{0}:{1}/","88.118.32.126",Port));
 
        Listener.Prefixes.Add(
            string.Format("http://{0}:{1}/","*",Port)); //added these for testing,but still nothing
 
        Listener.Prefixes.Add(
            string.Format("http://::ffff:{0}:{1}/",but still nothing
 
        Listener.Start();
        Listener.BeginGetContext(ProcessRequest,Listener);
 
        Log.Add(string.Format("HTTP Server started on port {0}",Port),LogType.Info,true);
    }
 
    private void ProcessRequest(IAsyncResult result)
    {
        HttpListener listener = (HttpListener)result.AsyncState;
        HttpListenerContext context = listener.EndGetContext(result);
 
        HttpListenerRequest request = context.Request;
        HttpListenerResponse response = context.Response;
 
        string[] UrlParts = request.RawUrl.Split('/');
        Response output;
 
        if (request.RawUrl == "/index")
            output = new Response(context.Response.OutputStream,ResponseType.Stats,UrlParts,Log);
 
        response.ContentLength64 = output.Size;
        response.ContentType = output.Header;
 
        output.Send();
 
        if (result.IsCompleted)
            Log.Add(String.Format("OUT > {1,15} {0,8} bytes -> {2}",output.Size,request.RemoteEndPoint.Address,request.RawUrl),true);
 
        Listener.BeginGetContext(ProcessRequest,Listener);
    }
}
