Photon Server 实现注册与登录(三) --- 前端UI设计和发起请求

一、打开之前的测试项目。先将服务端代码编译一下，在 bin/Debug/目录下会发现有一个Common.dill。我们相应导入到前端使用。直接拖拽到相应地方

UI相应布局属于前端操作，这里就不做介绍了。详细查看视频：https://www.bilibili.com/video/av35109390/?p=70

二、代码处理：跟后端一样，前端发起请求的地方也会随着项目变大而变多，所以也得单独区分出每个请求独自管理。

Request.cs 请求基类
LoginRequest.cs  登录请求逻辑
RegiesterRequest.cs  注册请求连接

LoginPanel.cs  登录面挂载脚本
ReginsterPanel.cs 注册脚本挂载脚

三、调整PhotonManager.cs 管理类

　　（1）、添加字典,管理所以请求

    private Dictionary<OperationCode,Request> ResquesDict = new Dictionary<OperationCode, Request>();

       (2)、分配peer

    public static PhotonPeer Peer
    {
        get { return peer; }
    }

       (3)、添加两个函数,管理请求

    public void AddRequest(Request rest)
    {
        ResquesDict.Add(rest.OpCode,rest);
    }

    public void RemoveRequest(Request rest)
    {
        ResquesDict.Remove(rest.OpCode);
    }

      (4)、修改OnOperationResponse() 函数，实现接收服务端返回数据的分发

 /// <summary>
    /// 客户端请求后,服务端响应,返回数据
    /// </summary>
    /// <param name="operationResponse"></param>
    public void OnOperationResponse(OperationResponse operationResponse)
    {
        //服务端返回的code
        OperationCode opCode = (OperationCode)operationResponse.OperationCode;
        Request request = null;
        
        //根据code查找相应请求
        bool tmp = ResquesDict.TryGetValue(opCode, out request);
        
        if (tmp)
        {
            //如果存在,分发给相应OnOperationResponse去处理自己的接收数据逻辑
            request.OnOperationResponse(operationResponse);
        }
        else
        {
            Debug.Log("没找到响应处理对象");
        }
    }

　（5）、完整代码

using System;
using System.Collections;
using System.Collections.Generic;
using System.Reflection.Emit;
using Common;
using UnityEngine;
using ExitGames.Client.Photon;

public class PhotonManager : MonoBehaviour,IPhotonPeerListener
{
    //单例模式,保证只有一个链接服务器
    public static PhotonManager Instance;
    private static PhotonPeer peer;
    private bool connected;
    private Dictionary<OperationCode,Request> ResquesDict = new Dictionary<OperationCode, Request>();
    public static PhotonPeer Peer
    {
        get { return peer; }
    }

    private void Awake()
    {
        if (Instance == null)
        {
            Instance = this;
            DontDestroyOnLoad(this.gameObject);
        }else if (Instance != this)
        {
            Destroy(this.gameObject);
            return;
        }
    }

    // Start is called before the first frame update
    void Start()
    {
        Debug.Log("111------开始连接----");
        
        peer = new PhotonPeer(this, ConnectionProtocol.Udp);
        peer.Connect("127.0.0.1:5055","MyGame1");
        connected = false;
    }

    // Update is called once per frame
    void Update()
    {
        Debug.Log("update------" + connected);
        
        peer.Service();
    }

    private void OnDestroy()
    {
        if (peer != null && peer.PeerState == PeerStateValue.Connected)
        {
            peer.Disconnect();
        }
    }

    public void DebugReturn(DebugLevel level, string message)
    {
    }

    /// <summary>
    /// 客户端请求后,服务端响应,返回数据
    /// </summary>
    /// <param name="operationResponse"></param>
    public void OnOperationResponse(OperationResponse operationResponse)
    {
        //服务端返回的code
        OperationCode opCode = (OperationCode)operationResponse.OperationCode;
        Request request = null;
        
        //根据code查找相应请求
        bool tmp = ResquesDict.TryGetValue(opCode, out request);
        
        if (tmp)
        {
            //如果存在,分发给相应OnOperationResponse去处理自己的接收数据逻辑
            request.OnOperationResponse(operationResponse);
        }
        else
        {
            Debug.Log("没找到响应处理对象");
        }
    }

    /// <summary>
    /// 连接状态发生改变时
    /// </summary>
    /// <param name="statusCode"></param>
    public void OnStatusChanged(StatusCode statusCode)
    {
        Debug.Log("serStatus-----" + statusCode.ToString());
        
        switch (statusCode)
        {
            case StatusCode.Connect:
                connected = true;
                break;
            default:
                connected = false;
                break;
        }
    }

    public void OnEvent(EventData eventData)
    {
        switch (eventData.Code)
        {
            case 1:
                break;
            case 2:

                break;
            default:
                break;
        }
    }

    public void AddRequest(Request rest)
    {
        ResquesDict.Add(rest.OpCode,rest);
    }

    public void RemoveRequest(Request rest)
    {
        ResquesDict.Remove(rest.OpCode);
    }
}

四、请求类

　　（1）、Request.cs 基类

using System;
using Common;
using ExitGames.Client.Photon;
using UnityEngine;

public abstract class Request: MonoBehaviour
{
    //定义请求code
    public OperationCode OpCode;
    
    public abstract void DefaultRequest(); //发送请求
    
    public abstract void OnOperationResponse(OperationResponse operationResponse); //接收返回的数据

    public virtual void Start()
    {
        //从管理类中添加该请求
        PhotonManager.Instance.AddRequest(this);
    }

    public void OnDestroy()
    {
        //从管理类中移除该请求
        PhotonManager.Instance.RemoveRequest(this);
    }
}

　　（2）、登陆类 LoginRequest.cs 

using System.Collections.Generic;
using Common;
using ExitGames.Client.Photon;
using UnityEngine;

public class LoginRequest : Request
{
    //通过代码赋值,所有在UI界面上隐藏掉
    [HideInInspector]
    public string UserName;
    [HideInInspector]
    public string Password;

    //获取UI面板
    private LoginPanel loginPanel;

    public override void Start()
    {
        //调用基类Start,将登陆请求添加到管理类中
        base.Start();
        loginPanel = GetComponent<LoginPanel>();
    }
    public override void DefaultRequest()
    {
        //登录请求发起
        Dictionary<byte,object> data = new Dictionary<byte, object>();
        data.Add((byte) ParameterCode.UserName,UserName);
        data.Add((byte) ParameterCode.Password,Password);
        
        //通过Peer发送请求给服务端
        PhotonManager.Peer.OpCustom((byte)OpCode,data,true);
    }
    
    public override void OnOperationResponse(OperationResponse operationResponse)
    {
        //接收服务端的返回响应,将返回code给面板,由面板来处理接下来的逻辑(是提示错误还是跳转场景)
        ReturnCode returnCode = (ReturnCode) operationResponse.ReturnCode;
        loginPanel.OnLiginResponse(returnCode);
    }
}

       (3)、登陆面板脚本  LoginPannel.cs

using System;
using System.Collections;
using System.Collections.Generic;
using Common;
using UnityEngine;
using UnityEngine.UI;

public class LoginPanel : MonoBehaviour
{
    //以下public参数通过UI拖拽进行赋值
    #region Tags
    
    //注册面板,用于点击注册时显示该面板
    public GameObject registerPanel;
    //控件
    public InputField username;
    public InputField password;
    public Text hintmessage;

    //登陆请求类
    private LoginRequest loginRequest;
    
    #endregion
   
    private void Start()
    {
        //从面板中获取请求类(面板脚本和请求类都挂载到请求面板UI中)
        loginRequest = GetComponent<LoginRequest>();
    }

    public void OnLoginButton()
    {
        //点击登陆按钮时,发送请求
        hintmessage.text = "";
        
        loginRequest.UserName = username.text;
        loginRequest.Password = password.text;
        
        //调用请求类中的发起请求
        loginRequest.DefaultRequest();
    }

    public void OnRegisterButton()
    {
        //点击注册时,隐藏登陆UI,显示注册UI
        gameObject.SetActive(false);
        registerPanel.SetActive(true);
    }

    public void OnLiginResponse(ReturnCode returnCode)
    {
        //服务端响应返回数据时,请求类会将返回信息传递到该函数
        Debug.Log("-----返回code" + returnCode);
        
        if (returnCode == ReturnCode.Success)
        {
            //登录成功,调整下一个场景
            Debug.Log("--登陆成功----");
        }
        else
        {
            hintmessage.text = "用户名或密码错误";
        }
    }
}

      注册类和注册面板跟登陆相同逻辑

     (4)、注册类 ReginesterRequest.cs

using System.Collections;
using System.Collections.Generic;
using Common;
using ExitGames.Client.Photon;
using UnityEngine;

public class RegiesterRequet : Request
{
    [HideInInspector]
    public string username; 
    [HideInInspector]
    public string password;

    private ReginsterPanel reginsterPanel;

    public override void Start()
    {
        base.Start();
        reginsterPanel = GetComponent<ReginsterPanel>();
    }

    public override void DefaultRequest()
    {
        //登录请求发起
        Dictionary<byte,object> data = new Dictionary<byte, object>();
        data.Add((byte) ParameterCode.UserName,username);
        data.Add((byte) ParameterCode.Password,password);
        
        PhotonManager.Peer.OpCustom((byte)OpCode,data,true);
    }

    public override void OnOperationResponse(OperationResponse operationResponse)
    {
        ReturnCode returnCode = (ReturnCode) operationResponse.ReturnCode;
        reginsterPanel.OnReigsterResponse(returnCode);
    }
    
}

    (5)、注册面板  ReginsterPanel.cs

using System;
using System.Collections;
using System.Collections.Generic;
using Common;
using UnityEngine;
using UnityEngine.UI;

public class ReginsterPanel : MonoBehaviour
{
    public GameObject loginPanel;

    public InputField username;
    public InputField password;
    public Text hintmessage;

    private RegiesterRequet regiesterRequet;

    private void Start()
    {
        regiesterRequet = GetComponent<RegiesterRequet>();
    }

    public void OnRegisterButton()
    {
        hintmessage.text = "";
            
        regiesterRequet.username = username.text;
        regiesterRequet.password = password.text;
        
        regiesterRequet.DefaultRequest();
    }
    
    public void OnBackBtn()
    {
        loginPanel.SetActive(true);
        gameObject.SetActive(false);
    }

    public void OnReigsterResponse(ReturnCode returnCode)
    {
        if (returnCode == ReturnCode.Success)
        {
            hintmessage.text = "注册成功,请返回登录";
        }
        else
        {
            hintmessage.text = "用户名重复,请重新修改用户名";
        }
    }
}

前端UI和请求、响应逻辑基本完成。接下来进行服务端响应。
