Unity3D使用WebSocket通信相关实现

基于Unity3D通过WebSocket进行通信，传输数据

一、导入插件

点击链接https://download.csdn.net/download/Z_ning/12535526进行下载、解压后导入unity中

二、相关脚本代码

1. 这里我创建了DataMagnage脚本
2. 引入头文件（我这里是直接粘贴我项目中的代码、引入了其他的头文件，不需要的头文件呈灰色删掉就好）

   using System;
   using System.Text;
   using UnityEngine;
   using UnityEngine.UI;
   using BestHTTP.WebSocket;
   using System.Collections.Generic;
   using Newtonsoft.Json.Linq;
   using System.Collections;
   using System.Threading;

    

3. 相关连接、初始化以及接收数据、关闭、抛出异常代码

   /// <summary>
       /// --------------------这是需要连接的URL地址
       /// </summary>
       public string url = "ws://localhost:8080//websocket/";
    
       private WebSocket webSocket;
    
       private void Init()
       {
           webSocket = new WebSocket(new Uri(url));
           webSocket.OnOpen += OnOpen;
           webSocket.OnMessage += OnMessageReceived;
           webSocket.OnError += OnError;
           webSocket.OnClosed += OnClosed;    
       }
    
       private void AntiInit()
       {
           webSocket.OnOpen = null;
           webSocket.OnMessage = null;
           webSocket.OnError = null;
           webSocket.OnClosed = null;
           webSocket = null;
       }
   
       public void Connect()
       {
           webSocket.Open();
           print("发送连接");
       }
   
       private byte[] getBytes(string message)
       {
           byte[] buffer = Encoding.Default.GetBytes(message);
           return buffer;
       }
       public void Send(string str)
       {
           webSocket.Send(str);
       }
   
       public void Close()
       {
           webSocket.Close();
       }
       void OnOpen(WebSocket ws)
       {
           Debug.Log("连接成功");     
           
       }
      /// <summary>
       /// 接收信息
       /// </summary>
       /// <param name="ws"></param>
       /// <param name="msg">接收内容</param>
       void OnMessageReceived(WebSocket ws,string msg)
       {
           Debug.Log(msg);
           SetLog(msg);
       }
       /// <summary>
       /// 关闭连接
       /// </summary>
       void OnClosed(WebSocket ws, UInt16 code, string message)
       {
           Debug.Log(message);
           setConsoleMsg(message);
           antiInit();
           init();
       }
   
       private void OnDestroy()
       {
           if (webSocket != null && webSocket.IsOpen)
           {
               webSocket.Close();
               antiInit();
           }
       }
      
       /// <summary>
       /// Called when an error occured on client side
       /// </summary>
       void OnError(WebSocket ws, Exception ex)
       {
           string errorMsg = string.Empty;
   #if !UNITY_WEBGL || UNITY_EDITOR
           if (ws.InternalRequest.Response != null)
               errorMsg = string.Format("Status Code from Server: {0} and Message: {1}",      ws.InternalRequest.Response.StatusCode, ws.InternalRequest.Response.Message);
   #endif
           Debug.Log(errorMsg);
           setConsoleMsg(errorMsg);
           antiInit();
           init();
       }

4. 然后就是调用方法，如果直接在进入场景后调用就把init();Connect();两个方法写在Start()里面就行了。

三、总结

我是直接在我项目中将相关代码粘出来的、就不再写Demo了。

注意：

建议把该脚本和BestHTTP文件夹放在一起，不然可能会报错……
