Unity使用webSocket与服务器通信（一）搭建一个简单地服务器和客户端

你想在unity WebGL里面使用TCP通信吗，那么你可以用一用webSocket。当然，桌面端也可以使用webSocket，这样Unity多平台发布的时候，业务层的通信代码可以使用一套，而不是桌面用socket，网页用http…

一、什么是webSocket？

顾名思义，它就是web版的socket？那什么是socket呢？…

二、Unity中webSocket相关的包有哪些？

三、Unity客户端的实现

• 联网演示
• 绑定脚本
• 代码清单代码来自NativeWebSocket官网demo，略作修改

usingSystem;usingSystem.Collections;usingSystem.Collections.Generic;usingUnityEngine;usingUnityEngine.UI;usingNativeWebSocket;publicclassConnection:MonoBehaviour{WebSocket websocket;publicText textLog;// Start is called before the first frame updateasyncvoidStart(){
        websocket =newWebSocket("ws://192.168.0.146:8081");

        websocket.OnOpen +=()=>{
            Debug.Log("Connection open!");
            textLog.text =$"Connection open! {Time.realtimeSinceStartup} \n {textLog.text}";};

        websocket.OnError +=(e)=>{
            Debug.Log("Error! "+ e);
            textLog.text =$"Error:{e}{Time.realtimeSinceStartup} \n {textLog.text}";};

        websocket.OnClose +=(e)=>{
            Debug.Log("Connection closed!");
            textLog.text =$"Connection closed! {Time.realtimeSinceStartup} \n {textLog.text}";};

        websocket.OnMessage +=(bytes)=>{
            Debug.Log("OnMessage!");
            textLog.text =$"OnMessage! {Time.realtimeSinceStartup} \n {textLog.text}";
            Debug.Log(bytes);// getting the message as a stringvar message = System.Text.Encoding.UTF8.GetString(bytes);
            textLog.text =$"消息内容：{message}{Time.realtimeSinceStartup} \n {textLog.text}";//Debug.Log("OnMessage! " + message);};// Keep sending messages at every 0.3sInvokeRepeating("SendWebSocketMessage",0.0f,0.3f);// waiting for messagesawait websocket.Connect();}voidUpdate(){#if !UNITY_WEBGL || UNITY_EDITOR
        websocket.DispatchMessageQueue();#endif}asyncvoidSendWebSocketMessage(){if(websocket.State == WebSocketState.Open){// Sending bytesawait websocket.Send(newbyte[]{10,20,30});// Sending plain textawait websocket.SendText("plain text message");}}privateasyncvoidOnApplicationQuit(){await websocket.Close();}}

四、服务端的实现（C# WinForm）

1、服务器端用到的包

2、主要代码

代码来自官网Demo，略有修改

usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Diagnostics;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;usingSystem.Windows.Forms;usingFleck;namespaceWinFormsApp1{publicpartialclassForm1:Form{publicForm1(){InitializeComponent();}privatevoidbutton1_Click(object sender,EventArgs e){var server =newWebSocketServer("ws://192.168.0.146:8081");//ws://localhost:8081    ws://127.0.0.0:8181
            server.Start(socket =>{
                socket.OnOpen =()=>{
                    Debug.WriteLine($"有新用户连入：{socket.ConnectionInfo.ClientIpAddress}");};
                socket.OnClose =()=>{
                    Debug.WriteLine($"用户断开连接：{socket.ConnectionInfo.ClientIpAddress}");};
                socket.OnMessage = message =>{
                    socket.Send($"服务器收到消息 : {DateTime.Now.ToString()}");
                    Debug.WriteLine($"收到一条消息，来自：{socket.ConnectionInfo.ClientIpAddress}");};});

            Debug.WriteLine("服务器已经启动！");}}}

五、客户端的WebGL和Win 桌面测试

桌面和webGL都没问题、这样，可以一套代码打天下。
以前用socket在桌面(包括一体头盔)，在web端只能用http，现在可以统一了。
