上一讲中主要介绍了服务器的简单知识，，配置服务器和客户端连接.
第二讲介绍客户端请求服务器，服务器响应操作，我们就以一个简单的用户登录为基础介绍吧
一、服务器端
按照上一篇教程我们配置好简单的photon服务器，但是只能用于连接服务器和断开服务器操作，其他的基本没有提到，今天是要在上一讲基础上添加内容.
主要是在MyPeer.cs类的OnOperationRequest方法中实现，代码如下：
using System;using System.Collections.Generic;using Photon.SocketServer;using PhotonHostRuntimeInterfaces;namespace MyServer{using Message;using System.Collections;public class MyPeer : PeerBase{Hashtable userTable;public MyPeer(IRpcProtocol protocol,IPhotonPeer photonPeer): base(protocol, photonPeer){userTable = new Hashtable();userTable.Add("user1", "pwd1");userTable.Add("user2", "pwd2");userTable.Add("user3", "pwd3");userTable.Add("user4", "pwd4");userTable.Add("user5", "pwd5");}protected override void OnDisconnect(PhotonHostRuntimeInterfaces.DisconnectReason reasonCode, string reasonDetail){}protected override void OnOperationRequest(OperationRequest operationRequest, SendParameters sendParameters){switch (operationRequest.OperationCode) {case (byte)OpCodeEnum.Login:string uname = (string)operationRequest.Parameters[(byte)OpKeyEnum.UserName];string pwd = (string)operationRequest.Parameters[(byte)OpKeyEnum.PassWord];if (userTable.ContainsKey(uname) && userTable[uname].Equals(pwd))//login success{SendOperationResponse(new OperationResponse((byte)OpCodeEnum.LoginSuccess, null),new SendParameters());}else{ //login fauledSendOperationResponse(new OperationResponse((byte)OpCodeEnum.LoginFailed, null), new SendParameters());}break;}}}}OnOperationRequest方法中验证用户名和密码，然后发送响应给客户端.需要用到的枚举一个类如下：using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace MyServer.Message{enum OpCodeEnum : byte{//loginLogin = 249,LoginSuccess = 248,LoginFailed = 247,//roomCreate = 250,Join = 255,Leave = 254,RaiseEvent = 253,SetProperties = 252,GetProperties = 251}enum OpKeyEnum : byte{RoomId = 251,UserName = 252,PassWord = 253}}二、客户端
客户端过程需要请求服务器并接收服务器的响应下面上代码，就一个类搞定：
using UnityEngine;using System.Collections;using System.Collections.Generic;using ExitGames.Client.Photon;public class TestConnection : MonoBehaviour,IPhotonPeerListener {public string address;PhotonPeer peer;ClientState state = ClientState.DisConnect;string username = "";string password = "";// Use this for initializationvoid Start () {peer = new PhotonPeer(this,ConnectionProtocol.Udp);}// Update is called once per framevoid Update () {peer.Service();}public GUISkin skin;void OnGUI(){GUI.skin = skin;switch(state){case ClientState.DisConnect:GUI.Label(new Rect(Screen.width/2,Screen.height/2-30,300,40),"click the button to connect.");if(GUI.Button(new Rect(Screen.width/2,Screen.height/2,100,30),"Connect")){peer.Connect(address,"MyServer");state = ClientState.Connecting;}break;case ClientState.Connecting:GUI.Label(new Rect(Screen.width/2,Screen.height/2-30,300,40),"Connecting to Server…");break;case ClientState.Connected:GUILayout.BeginArea(new Rect((Screen.width-500)/2,(Screen.height-400)/2,500,400));//GUILayout.BeginVertical();GUILayout.Label("Connect Success!
