Unity组件开发--长连接webSocket

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
    //{
    //    [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

        HANDSHAKE = 6,
        ERROR = 7,
        NOTIFY = 8
    }

    public class PackageProtocol
    {
        //获取cmd
        public static uint getCmd(uint merge)
        {

        }
        //获取subCmd
        public static uint getSubCmd(uint merge)
        {
            return merge & 0xFFFF;
        }
        //获取mergeCmd
        public static uint getMergeCmd(uint cmd, uint subCmd)
        {

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 : IProto
    public class Proto : IProto
    {
        public string name; //������
        public uint mid { get; set; } //��id
        public uint sid { get; set; } //��id

        public uint mergeid;
        public int typ; //������
        //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
        {

        }


        //public Dictionary protos = new Dictionary();

        public Dictionary protos = new Dictionary();

        public Dictionary id2proto = new Dictionary();


        public void Add(string name, Proto 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("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

            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()
        {

            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;

            byte[] package = PackageProtocol.Encode(
                PackageType.HEARTBEAT);
            socket.SendAsync(package);//*/
        }

        internal void Setup(uint interval, Action onServerTimeout, WebSocket socket)
        {
            this.socket = socket;

            SendHeartbeatPack();
        }

        internal void ResetTimeout(uint interval)
        {

            this.enabled = false;
            t = 0;
        }
    }
}

7.定义协议类Protocol：

using Cysharp.Threading.Tasks;
using ProtoBuf;
using System;
using System.Collections.Generic;
using System.IO;
using System.Net;
