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

news 2025/8/8 21:54:09

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 updateasync 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 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();}void Update(){
#if !UNITY_WEBGL || UNITY_EDITORwebsocket.DispatchMessageQueue();
#endif}async void SendWebSocketMessage(){if (websocket.State == WebSocketState.Open){// Sending bytesawait websocket.Send(new byte[] { 10, 20, 30 });// Sending plain textawait websocket.SendText("plain text message");}}private async void OnApplicationQuit(){await websocket.Close();}}

四、服务端的实现（C# WinForm）

请添加图片描述

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

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://127.0.0.0:8181server.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！");}}
}
