端口被阻止时连接到共享主机上的 Websocket

如何解决端口被阻止时连接到共享主机上的 Websocket

我在 c# (asp.net) 中构建了一个程序，该程序使用 WebSocket4Net 连接到 wss://stream.binance.com:9443/ws，并获取公开的股票代码数据。

我的应用程序在 localhost 上运行良好，但在我的托管服务提供商上，我收到错误 "An attempt was made to access a socket in a way forbidden by its access permissions"，如果我理解正确，这是端口阻塞的问题。

我的托管服务提供商允许我为特定 ip 地址启用特定端口，但在这种情况下，我没有远程主机的 ip 地址 wss://stream.binance.com:9443/ws

有没有办法在连接打开或收到消息时找出远程主机的IP地址？

我的代码：

using System.Collections.Generic;
using Newtonsoft.Json;
using WebSocket4Net;
public static class BinanceWShandler
{
    static WebSocket ws;
    internal static bool isOpen { get; private set; }

    public static void Start()
    {

        ws = new WebSocket("wss://stream.binance.com:9443/ws");
        ws.Opened += Ws_Opened;
        ws.Closed += Ws_Closed;
        ws.Error += Ws_Error;
        ws.MessageReceived += Ws_MessageReceived;
        ws.EnableAutoSendPing = true;
        ws.open();
    }

    private static void Ws_Error(object sender,SuperSocket.ClientEngine.ErrorEventArgs e)
    {
    }

    private static void Ws_Closed(object sender,EventArgs e)
    {
    }

    private static void Ws_Opened(object sender,EventArgs e)
    {
        Request_Individual_Ticker obj = new Request_Individual_Ticker();
        obj.method = "SUBSCRIBE";
        List<string> pars = new List<string>();
        pars.Add("!bookTicker");
        obj.@params = pars;
        obj.id = 1;
        string JSONstring = JsonConvert.SerializeObject(obj);
        ws.Send(JSONstring);
        isOpen = true;
    }

    private static void Ws_MessageReceived(object sender,MessageReceivedEventArgs e)
    {
        SignalRChat.Hubs.ChatHub.instance.SendBinanceWS(e.Message);
    }

    public class Request_Individual_Ticker
    {
        public string method { get; set; }
        public List<string> @params { get; set; }
        public int id { get; set; }
    }
}
