1.下载安装UnityWebSocket 插件

https://gitee.com/cambright/UnityWebSocket/

引入unity项目：

2.定义消息体结构：ExternalMessage和包结构Package：

using ProtoBuf;
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;namespace UTNET
{[ProtoContract]public class ExternalMessage{[ProtoMember(1)]// 请求命令类型: 0 心跳，1 业务public int cmdCode;// 协议开关，用于一些协议级别的开关控制，比如 安全加密校验等。 : 0 不校验[ProtoMember(2)]public int protocolSwitch;// 业务路由（高16为主, 低16为子）[ProtoMember(3)]public uint cmdMerge;// 响应码: 0:成功, 其他为有错误[ProtoMember(4,DataFormat = DataFormat.ZigZag)]public int responseStatus;// 验证信息（错误消息、异常消息），通常情况下 responseStatus == -1001 时， 会有值[ProtoMember(5)]public string validMsg;// 业务请求数据[ProtoMember(6)]public byte[] data;// 消息标记号；由前端请求时设置，服务器响应时会携带上；[ProtoMember(7, DataFormat = DataFormat.ZigZag)]public int msgId;}[ProtoContract]public class Package{[ProtoMember(1)]public uint packageType;[ProtoMember(2)]public string route = null;[ProtoMember(3)]public uint packID = 0;[ProtoMember(4)]public byte[] buff = null;[ProtoMember(5)]public string modelName = null;}//[ProtoContract]//public class Message<T>//{//    [ProtoMember(1)]//    public uint err;//    [ProtoMember(2)]//    public string errMsg = default;//    [ProtoMember(3)]//    public T data = default;//    public Message() { }//    public Message(uint err, string errMsg, T info)//    {//        this.err = err;//        this.errMsg = errMsg;//        this.data = info;//    }//}[ProtoContract]public class HandShake{[ProtoMember(1)]public string token;}[ProtoContract]public class Heartbeat{[ProtoMember(1)]public uint heartbeat;}
}

3.定义包协议结构：PackageProtocol

using ProtoBuf;
using System;
using System.IO;
using System.Text;
using UnityEngine.XR;namespace UTNET
{public enum PackageType{HEARTBEAT = 1,REQUEST = 2,PUSH = 3,KICK = 4,RESPONSE = 5,HANDSHAKE = 6,ERROR = 7,NOTIFY = 8}public class PackageProtocol{//获取cmdpublic static uint getCmd(uint merge){return merge >> 16;}//获取subCmdpublic static uint getSubCmd(uint merge){return merge & 0xFFFF;}//获取mergeCmdpublic static uint getMergeCmd(uint cmd, uint subCmd){return (cmd << 16) + subCmd;}public static byte[] Encode(PackageType type){Package sr = new Package(){packageType = (uint)type};return Serialize(sr);}public static byte[] Encode<T>(PackageType type, uint packID, string route, T info, string modelName = null){Package sr = new Package(){packageType = (uint)type,packID = packID,route = route,buff = Serialize<T>(info),modelName = modelName};return Serialize(sr);}public static byte[] EncodeEx<T>(uint packID, uint cmdMerge, T info){//Package sr = new Package()//{//    packageType = (uint)type,//    packID = packID,//    route = route,//    buff = Encoding.Default.GetBytes(SerializeEx<T>(info)),//};//return SerializeEx(sr);ExternalMessage sr = new ExternalMessage(){cmdCode = 100,protocolSwitch = 1,cmdMerge = cmdMerge,responseStatus = 0,validMsg = "",data = Encoding.UTF8.GetBytes(SerializeEx<T>(info)),};return Serialize(sr);}public static byte[] Encode<T>(uint packID, uint cmdMerge, T info){ExternalMessage sr = new ExternalMessage(){cmdCode = 100,protocolSwitch = 1,cmdMerge = cmdMerge,responseStatus = 0,validMsg = "",data = Serialize<T>(info),msgId = (int)packID,};return Serialize(sr);}public static string SerializeEx<T>(T t){using (MemoryStream ms = new MemoryStream()){Serializer.Serialize<T>(ms, t);return Encoding.UTF8.GetString(ms.ToArray());}}public static byte[] Serialize<T>(T info){if (typeof(T) == typeof(int)){int value = (int)Convert.ChangeType(info, typeof(int));value = (value << 1);info = (T)Convert.ChangeType(info, typeof(T));}MemoryStream ms = new MemoryStream();Serializer.Serialize(ms, info);byte[] buff = ms.ToArray();ms.Close();return buff;//try//{//    //涉及格式转换，需要用到流，将二进制序列化到流中//    using (MemoryStream ms = new MemoryStream())//    {//        //使用ProtoBuf工具的序列化方法//        Serializer.Serialize<T>(ms, info);//        //定义二级制数组，保存序列化后的结果//        byte[] result = new byte[ms.Length];//        //将流的位置设为0，起始点//        ms.Position = 0;//        //将流中的内容读取到二进制数组中//        ms.Read(result, 0, result.Length);//        return result;//    }//}//catch (Exception ex)//{//    return null;//}}public static ExternalMessage Decode(byte[] buff){//protobuf反序列化MemoryStream mem = new MemoryStream(buff);ExternalMessage rs = Serializer.Deserialize<ExternalMessage>(mem);mem.Close();return rs;}public static T DecodeInfo<T>(byte[] buff){if (buff == null) return default;T rs;if (typeof(T) == typeof(int)){int value;using (var stream = new MemoryStream(buff)){value = Serializer.Deserialize<int>(stream);}//转zig zagvalue = (value >> 1) ^ -(value & 1);rs = (T)Convert.ChangeType(value, typeof(T));}else{MemoryStream mem = new MemoryStream(buff);rs = Serializer.Deserialize<T>(mem);mem.Close();}return rs;}//public static T MyMethod<T>(byte[] buff) where T : Object//{//    return null;//}}
}

4.引入UniTask插件：UniTask中文使用指南(一) - 知乎

UniTask保姆级教程_unitask安装-CSDN博客

项目地址：GitHub - Cysharp/UniTask: Provides an efficient allocation free async/await integration for Unity.

5.定义协议索引管理，添加长连接的协议：ProtoMaps

using System;
using System.Collections.Generic;namespace UTNET
{public interface IProto{}//R ��������, S ��������//public class Proto<R, S> : IProtopublic class Proto : IProto{public string name; //Э������public uint mid { get; set; } //��idpublic uint sid { get; set; } //��idpublic uint mergeid;public int typ; //Э������//public R r;//public S s;public Proto(string name, uint mid, uint sid, int typ){this.name = name;this.mid = mid;this.sid = sid;this.typ = typ;}}public class ProtoMaps{private static readonly ProtoMaps instance = new ProtoMaps();public static ProtoMaps Instance{get { return instance; }}//public Dictionary<string, IProto> protos = new Dictionary<string, IProto>();public Dictionary<string, Proto> protos = new Dictionary<string, Proto>();public Dictionary<uint, Proto> id2proto = new Dictionary<uint, Proto>();public void Add(string name, Proto pb){protos.Add(name, pb);}public void SortById(){foreach (var item in protos){var pb = item.Value;uint mergeid = PackageProtocol.getMergeCmd(pb.mid, pb.sid);pb.mergeid = mergeid;id2proto.Add(mergeid, pb);}}public ProtoMaps(){this.Add("login", new Proto("login", 1, 2, 1));this.Add("registerInfo", new Proto("registerInfo", 1, 1, 1));this.Add("enterRoom", new Proto("enterRoom", 1, 13, 3));this.Add("roleMove", new Proto("roleMove", 4, 3, 3));//this.Add("onNewRoleEnter", new Proto("onNewRoleEnter", 7, 1, 2));//服务器主动广播的角色退出this.Add("roleExitRoom", new Proto("roleExitRoom", 7, 2, 2));this.Add("talkMrg", new Proto("talkMrg", 1, 9, 3));//玩家点击的角色退出this.Add("playerExitRoom", new Proto("playerExitRoom", 1, 5, 3));this.Add("gameFrame", new Proto("gameFrame", 4, 2, 1));this.Add("gameObjUsed", new Proto("gameObjUsed", 4, 4, 3));this.Add("getOtherInfo", new Proto("getOtherInfo", 1, 23, 1));this.Add("heatBeat", new Proto("heatBeat", 1, 120, 1));SortById();}public Proto Name2Pb(string name){//Proto pb = ProtoMaps.Instance.protos[name];if (protos.ContainsKey(name)){return protos[name];}return null;}internal Proto GetByMergeId(uint cmdMerge){if (id2proto.ContainsKey(cmdMerge)){return id2proto[cmdMerge];}return null;}}}

6.定义心跳协议类：HeartBeatServiceGameObject

using System;
using UnityEngine;
using UnityWebSocket;
namespace UTNET
{public class HeartBeatServiceGameObject : MonoBehaviour{public Action OnServerTimeout;private WebSocket socket;public float interval = 0;public long lastReceiveHeartbeatTime;void Start(){}static DateTime dt = new DateTime(1970, 1, 1);public static long GetTimestamp(){TimeSpan ts = DateTime.Now.ToUniversalTime() - dt;return (long)ts.TotalSeconds;}public float t;void Update(){t += Time.deltaTime;if (t > interval){CheckAndSendHearbeat();t = 0;}}private void CheckAndSendHearbeat(){//檢查最後一次取得心跳包的時間是否小於客戶端心跳間隔時間long curTime = GetTimestamp();long intervalSec = curTime - lastReceiveHeartbeatTime;if (intervalSec > interval){//Debug.Log(string.Format("XXXX CheckAndSendHearbeat：s1:{0} l:{1} s:{2}", curTime, lastReceiveHeartbeatTime, intervalSec));this.enabled = false;OnServerTimeout?.Invoke();}else{//Debug.Log(string.Format(" CheckAndSendHearbeat：s1:{0} l:{1} s:{2}", curTime, lastReceiveHeartbeatTime, intervalSec));this.enabled = true;SendHeartbeatPack();}}public void HitHole(){lastReceiveHeartbeatTime = GetTimestamp();}private void SendHeartbeatPack(){//lastSendHeartbeatPackTime = DateTime.Now;byte[] package = PackageProtocol.Encode(PackageType.HEARTBEAT);socket.SendAsync(package);//*/}internal void Setup(uint interval, Action onServerTimeout, WebSocket socket){this.socket = socket;this.interval = (interval / 1000 )/2;this.OnServerTimeout = onServerTimeout;this.enabled = true;SendHeartbeatPack();}internal void ResetTimeout(uint interval){this.enabled = true;this.interval = (interval / 1000) / 2;t = 0;//long s1 = GetTimestamp();//long s = (s1 - lastReceiveHeartbeatTime);//Debug.Log(string.Format("ResetTimeout： s1:{0} l:{1} s:{2} s > interval:{3}", s1, lastReceiveHeartbeatTime, s, s > interval));lastReceiveHeartbeatTime = GetTimestamp();SendHeartbeatPack();}internal void Stop(){this.enabled = false;t = 0;}}
}

11.发送网络消息的应用：

UserInfo ret = await NetManager.Instance.client.RequestAsync<LoginVerify, UserInfo>("login", loginVer);

12.监听网络消息：

NetManager.Instance.Register<TankEnterRoom>("enterRoom", (ExternalMessage pack) =>
{Debug.Log("新玩家进去");this.onNewRoleEnter2(pack);
});

    public void onNewRoleEnter2(ExternalMessage pack) {TankEnterRoom info = PackageProtocol.DecodeInfo<TankEnterRoom>(pack.data);List<UserInfo> roleList = info.tankPlayerList;Debug.Log("新进入房间玩家列表" + roleList.ToString());long roleId = info.playerId;Debug.Log("新进入房间玩家id" + roleId);foreach (UserInfo vRole in roleList){Debug.Log("新进入房间玩家" + JsonUtility.ToJson(vRole));if (vRole.id == roleId && vRole.id!=PlayerData.Instance.PlayerId){if (!RolesManager.Instance.isExistRoleById(vRole.id)) {GuestinfoDataModel.Instance.OnNewRoleIntoRoom(vRole);RolesManager.Instance.synPlayer(vRole, true);} }}}
