首先我们需要一个websocket服务器，之前的博文中有做

Tomcat架设简单Websocket服务器

用的时候打开就行了，先不管它

Unity中新建场景

建UI(UGUI)

有一个连接按钮Button

一个信息输入框InputField

一个发送按钮Button

一个断开按钮Button

一个消息显示框Text

场景中建一个GameObject，在上面加个脚本，就叫WSMgr好了

用到了BestHTTP这个插件

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using BestHTTP;

using BestHTTP.WebSocket;

using System;

using BestHTTP.Examples;

using UnityEngine.UI;

using System.Text;

public class WSMgr : MonoBehaviour {

//public string url = "ws://localhost:8080/web1/websocket";

public string url = "ws://localhost:8080/web1/ws";

public InputField msg;

public Text console;

private WebSocket webSocket;

private void Start()

{

init();

}

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;

}

private void setConsoleMsg(string msg)

{

console.text = "Message: " + msg;

}

public void Connect()

{

webSocket.Open();

}

private byte[] getBytes(string message)

{

byte[] buffer = Encoding.Default.GetBytes(message);

return buffer;

}

public void Send()

{

webSocket.Send(msg.text);

}

public void Send(string str)

{

webSocket.Send(str);

}

public void Close()

{

webSocket.Close();

}

#region WebSocket Event Handlers

///

/// Called when the web socket is open, and we are ready to send and receive data

///

void OnOpen(WebSocket ws)

{

Debug.Log("connected");

setConsoleMsg("Connected");

}

///

/// Called when we received a text message from the server

///

void OnMessageReceived(WebSocket ws, string message)

{

Debug.Log(message);

setConsoleMsg(message);

}

///

/// Called when the web socket closed

///

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();

}

}

///

/// Called when an error occured on client side

///

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();

}

#endregion

}

Connect Send Close 三个方法对应的就是三个按钮的功能

OnOpen OnMessage OnError OnClose这四个一看就是Websocket的四个事件对应的方法

首先在Start方法中init()

点击Connect，连接

在输入框中输入，点击Send就发送

点击Close断开连接

底部的Text中会显示消息

同样，Tomcat服务端也有显示

发布WebGL测试可用
