最近題主在研究PhotonServer如何實現聯網功能時，在搭建伺服器與客戶端時遇到了許多小問題，題主在網上參照了siki老師的photonServer搭建教程，但是遇到的問題卻很多，原因是siki老師所講的版本是幾年前的版本，所以跟現在的新版本是有不同之處的，也由於題主沒有網路通訊的基礎，所以一直折騰了我不少時間，現在終於搞定了整個流程，現在我來為大家分享一下2017年最新的PhotonServer搭建教程。

客戶端 GameDemoChatClient

using ExitGames.Client.Photon;
using System;
using
 
 System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace GameDemoChatClient                   //客戶端
{

    class ChatServerListener : IPhotonPeerListener
    {
        public bool isConnected = false;

        public void DebugReturn(DebugLevel level, string
 
 message)
        {

        }

        public void OnEvent(EventData eventData)      //返回給客戶端時呼叫
        {
            //throw new NotImplementedException();
        }
        public void OnOperationResponse(OperationResponse operationResponse)     //得到伺服器端的響應
        {

            Dictionary<byte, object
 
> dict = operationResponse.Parameters;
            object v = null;
            dict.TryGetValue(1,out v);
            if (v == null)
            {

                Console.WriteLine("error code:" + operationResponse.ReturnCode + "     error message:" + operationResponse.DebugMessage);
            }
            else
            {
                Console.WriteLine("從服務端得到資料：" + v.ToString());
            }


        }

        public void OnMessage(object messages)
        {

        }

        public void OnStatusChanged(StatusCode statusCode)      //客戶端連線服務端成功時呼叫
        {
            switch (statusCode)
            {
                case StatusCode.Connect:
                    isConnected = true;
                    Console.WriteLine("連線成功！");
                    break;       
            }

        }
    }

    class Program
    {
        static void Main(string[] args)
        {
         string localhost = "127.0.0.1:4530";
         string ChatServer = "ChatServer";
        ChatServerListener listener = new ChatServerListener();
            PhotonPeer peer = new PhotonPeer(listener, ConnectionProtocol.Tcp);
            peer.Connect(localhost, ChatServer);     //連結伺服器
            Console.WriteLine("連線伺服器中......");
            while (listener.isConnected == false)
            {
                peer.Service();
            }
            Dictionary<byte, object> dict = new Dictionary<byte, object>();
            dict.Add(1,"username");
            dict.Add(2, "password");
            //向服務端傳送請求
            peer.OpCustom(1,dict,true);
            while (true) {
             peer.Service();
            }
        }
       }
    }

服務端：ChatPeer

using Photon.SocketServer;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using PhotonHostRuntimeInterfaces;
using Photon.SocketServer.Rpc;

namespace ChatServer
{
    class ChatPeer : ClientPeer    //新版本這個繼承ClientPeer
    {
        public ChatPeer(InitRequest initRequest) : base(initRequest)
        {

        }

        //當客戶端發起請求的時候呼叫
        protected override void OnOperationRequest(OperationRequest operationRequest, SendParameters sendParameters)
        {
            Dictionary<byte, object> dict = new Dictionary<byte, object>();
            dict.Add(1, "sucess");
            OperationResponse response = new OperationResponse(1, dict);
            SendOperationResponse(response,sendParameters);         
        }

        protected override void OnDisconnect(DisconnectReason reasonCode, string reasonDetail)
        {

        }
    }
}

PhotonServer.config配置檔案（重點）
這段程式碼寫在PhotonServer.config的語句塊裡，如圖：

 <ChatServer DisplayName="Chat Server">
    <TCPListeners>
      <TCPListener
         IPAddress="0.0.0.0"
         Port="4530"
         OverrideApplication="ChatServer">
        >
      </TCPListener>
    </TCPListeners>

    <Runtime
          Assembly="PhotonHostRuntime, Culture=neutral"
          Type="PhotonHostRuntime.PhotonDomainManager"
          UnhandledExceptionPolicy="Ignore">
    </Runtime>
    <Applications Default="ChatServer">
    <Application
    Name="ChatServer"
    BaseDirectory="ChatServer"
    Assembly="ChatServer"
    Type="ChatServer.ChatServer"
                ></Application>
          </Applications>
    </ChatServer>

ChatServer

using Photon.SocketServer;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ChatServer
{
  public  class ChatServer : ApplicationBase      //抽象類
    {
        protected override PeerBase CreatePeer(InitRequest initRequest)    //客戶端連線我們的服務端時呼叫這個方法
        {
            return new ChatPeer(initRequest);
        }

        protected override void Setup()
        {

        }

        protected override void TearDown()
        {
            throw new NotImplementedException();
        }
    }
}

配置完config檔案後，啟動PhotonServer,可以看到新的ChatServer的Application連線，啟動成功。

再看看是否能接收客戶端的請求訊息：

測試連線成功！

在這裡，我給大家展示一下常見的啟動錯誤，例如：

這都是因為PhotonServer.config配置檔案不對的問題！，按照我的新版本的配置即可解決問題！

下面進行unity的測試：
首先在PhotonServer的lib檔案下面匯入Photon3Unity3D.dll檔案到unity中。


掛載到任意GameObject上

PhotonServerEngine指令碼

using UnityEngine;
using System.Collections;
using ExitGames.Client.Photon;
using System.Collections.Generic;
using System.Runtime.CompilerServices;

public class PhotonServerEngine : MonoBehaviour,IPhotonPeerListener {

    private PhotonPeer peer;
    private bool isconnect = false;
    void Start()
    {
        peer = new PhotonPeer(this, ConnectionProtocol.Tcp);
        peer.Connect("127.0.0.1:4530", "ChatServer");//連線伺服器
    }

    void Update()
    {
        peer.Service();
    }

    void OnGUI()
    {
        if (isconnect)
        {
            if (GUILayout.Button("Send"))
            {
                Dictionary<byte, object> dict = new Dictionary<byte, object>();
                dict.Add(1, "username");
                dict.Add(2, "password");
                peer.OpCustom(1, dict, true);
            }

        }
    }

    public void DebugReturn(DebugLevel level, string message)
    {
        Debug.Log(level + ":" + message);
    }

    public void OnEvent(EventData eventData)
    {

    }

    public void OnOperationResponse(OperationResponse operationResponse)
    {
        Dictionary<byte, object> dict = operationResponse.Parameters;
        object val = null;
        dict.TryGetValue(1, out val);
        Debug.Log("getserver" + val.ToString());
    }

    public void OnStatusChanged(StatusCode statusCode)
    {
        switch (statusCode)
        {
            case StatusCode.Connect:
                isconnect = true;
                Debug.Log("Connect");
                break;
        }

    }
}

執行，成功連線到伺服器。
