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

2024-05-11 服务器 0

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

using System;using System.Collections;using System.Collections.Generic;using UnityEngine;using UnityEngine.UI;using NativeWebSocket;public class Connection : MonoBehaviour{    WebSocket websocket;    public Text textLog;    // Start is called before the first frame update    async void Start()    {        websocket = new WebSocket("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 string            var 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 0.3s        InvokeRepeating("SendWebSocketMessage", 0.0f, 0.3f);        // waiting for messages        await websocket.Connect();    }    void Update()    {#if !UNITY_WEBGL || UNITY_EDITOR        websocket.DispatchMessageQueue();#endif    }    async void SendWebSocketMessage()    {        if (websocket.State == WebSocketState.Open)        {            // Sending bytes            await websocket.Send(new byte[] { 10, 20, 30 });            // Sending plain text            await websocket.SendText("plain text message");        }    }    private async void OnApplicationQuit()    {        await websocket.Close();    }}

四、服务端的实现（C# WinForm）

2、主要代码

代码来自官网Demo，略有修改

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Diagnostics;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;using Fleck;namespace WinFormsApp1{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        private void button1_Click(object sender, EventArgs e)        {            var server = new WebSocketServer("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！");        }    }}
