Photon服务器入门二

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 fauled
                         SendOperationResponse(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
     {
         //login
         Login = 249,
         LoginSuccess = 248,
         LoginFailed = 247,

         //room
         Create = 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 initialization
     void Start () {
         peer = new PhotonPeer(this,ConnectionProtocol.Udp);
     }

     // Update is called once per frame
     void 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! Please Login.");
             //draw username
             GUILayout.BeginHorizontal();
             GUILayout.Label("UserName:");
             username = GUILayout.TextField(username);
             GUILayout.EndVertical();

             //draw password
             GUILayout.BeginHorizontal();
             GUILayout.Label("Password:");
             password = GUILayout.TextField(password);
             GUILayout.EndVertical();

             //draw buttons
             GUILayout.BeginHorizontal();
             if(GUILayout.Button("login")){
                 userLogin(username,password);
             }


             if(GUILayout.Button("canel")){
                 state = ClientState.DisConnect;
             }
             GUILayout.EndVertical();

             GUILayout.EndVertical();
             GUILayout.EndArea();

             break;
         case ClientState.ConnectFailed:
             GUI.Label(new Rect(Screen.width/2,Screen.height/2-30,300,40),"Connect Failed.");

             break;
         case ClientState.LoginSuccess:
             GUILayout.BeginArea(new Rect((Screen.width-500)/2,(Screen.height-400)/2,500,400));
             GUILayout.Label("Login Success!");
             GUILayout.EndArea();
             break;
         case ClientState.LoginFailed:
             GUILayout.BeginArea(new Rect((Screen.width-500)/2,(Screen.height-400)/2,500,400));
             GUILayout.Label("Login Failed!");
             GUILayout.EndArea();
             break;
         }
     }
