伺服器：使用c#寫的，用來持續給一個埠發資料
客戶端：using System; using System.Text; using System.Net; using System.Net.Sockets; using System.Text.RegularExpressions; using System.Security.Cryptography; using System.Threading; namespace WebSocketServer { class Program { static string byte_to_string(byte[] b) { string s = "";

這個是用來進行資料的接收
這個是用來獲得上面儲存的資料：using System; using UnityEngine; using System.Collections; using System.Collections.Generic; using System.Threading; using BestHTTP; using BestHTTP.WebSocket; public class WabData { /// <summary> /// The WebSocket address to connect /// </summary> private readonly string address = "ws://192.168.199.208:1818"; /// <summary> /// Default text to send /// </summary> private string _msgToSend = "Hello World!"; /// <summary> /// Debug text to draw on the gui /// </summary> private string _text = string.Empty; /// <summary> /// Saved WebSocket instance /// </summary> private WebSocket _webSocket; private Queue<DataInfo> _msgQueue = new Queue<DataInfo>(); public Queue<DataInfo> MsgQueue { get { return _msgQueue; } } public WebSocket WebSocket { get { return _webSocket; } } public string Address { get { return address; } } public string Text { get { return _text; } } public string MsgToSend { get { return _msgToSend; } set { _msgToSend = value; SendMsg(value); } } public void OpenWebSocket() { if (_webSocket == null) { // Create the WebSocket instance _webSocket = new WebSocket(new Uri(address)); if (HTTPManager.Proxy != null) _webSocket.InternalRequest.Proxy = new HTTPProxy(HTTPManager.Proxy.Address, HTTPManager.Proxy.Credentials, false); // Subscribe to the WS events _webSocket.OnOpen += OnOpen; _webSocket.OnMessage += OnMessageReceived; _webSocket.OnClosed += OnClosed; _webSocket.OnError += OnError; // Start connecting to the server _webSocket.Open(); } } public void SendMsg(string msg) { // Send message to the server _webSocket.Send(msg); } public void CloseSocket() { // Close the connection _webSocket.Close(1000, "Bye!"); } /// <summary> /// Called when the web socket is open, and we are ready to send and receive data /// </summary> void OnOpen(WebSocket ws) { Debug.Log("-WebSocket Open!\n"); } /// <summary> /// Called when we received a text message from the server /// </summary> void OnMessageReceived(WebSocket ws, string message) { DataInfo datainfo = JsonUtility.FromJson<DataInfo>(message); if (datainfo != null) _msgQueue.Enqueue(datainfo); } /// <summary> /// Called when the web socket closed /// </summary> void OnClosed(WebSocket ws, UInt16 code, string message) { Debug.Log(string.Format("-WebSocket closed!
