此章节介绍Chat聊天室示例--WebSocket & Cocos2d-JS
Chat是介绍如何使用WebSocket通讯协议作为服务端运行的示例,使用Cocos2d-JS作为客户端;可以从Github或OsChina上下载最新Sample。
使用6.7.9.6版本的Scut类库,聊天功能使用聊天中间件来快速创建服务;玩家的数据只存放在内存中不作持久化, Config中没有配置数据库连接串。
流程步骤
-
创建Chat项目,参考如何创建WebSocket的服务端项目;
-
定义协议结构,在JsonProtocol目录创建ResultData类
using System;
namespace GameServer.Script.CsScript.JsonProtocol
{
/// <summary>
/// Json result data
/// </summary>
public class ResultData
{
/// <summary>
///
/// </summary>
public int MsgId { get; set; }
/// <summary>
///
/// </summary>
public int ActionId { get; set; }
/// <summary>
///
/// </summary>
public int ErrorCode { get; set; }
/// <summary>
///
/// </summary>
public string ErrorInfo { get; set; }
/// <summary>
/// logic data
/// </summary>
public object Data { get; set; }
}
}
修改WebSocketActionDispatcher.cs的通讯结构
public class WebSocketActionDispatcher : ScutActionDispatcher
{
public override void ResponseError(BaseGameResponse response, ActionGetter actionGetter, int errorCode, string errorInfo)
{
var result = new ResultData()
{
MsgId = actionGetter.GetMsgId(),
ActionId = actionGetter.GetActionId(),
ErrorCode = errorCode,
ErrorInfo = errorInfo,
Data = null
};
//实现出错处理下发
response.BinaryWrite(Encoding.UTF8.GetBytes(MathUtils.ToJson(result)));
}
}
- 定义登录接口协议(Action1004),使用自定的身份认证MyLogin类,实现ILogin接口
#!MyLogin.cs
public class MyLogin : ILogin
{
public MyLogin(string userName)
{
PassportID = userName;
}
public string GetRegPassport()
{
return PassportID;
}
public bool CheckLogin()
{
var cache = new MemoryCacheStruct<ChatUser>();
ChatUser chatUser = cache.Find(t => t.UserName == PassportID);
if (chatUser != null)
{
UserID = chatUser.UserId.ToString();
return true;
}
//not user create it.
chatUser = new ChatUser()
{
UserId = (int)RedisConnectionPool.GetNextNo(typeof(ChatUser).FullName),
UserName = PassportID,
AccessTime = DateTime.Now
};
if (cache.TryAdd(chatUser.UserId.ToString(), chatUser))
{
UserID = chatUser.UserId.ToString();
return true;
}
return false;
}
public string PassportID { get; private set; }
public string UserID { get; private set; }
public int UserType { get; private set; }
public string Password { get; private set; }
public string SessionID { get; private set; }
}
#! Action1004.cs 部分代码
/// <summary>
/// login
/// </summary>
public class Action1004 : LoginAction
{
private string _userName;
public Action1004(ActionGetter actionGetter)
: base((short)1004, actionGetter)
{
//使用WebSocket的Text内容格式
IsWebSocket = true;
actionGetter.OpCode = OpCode.Text;
}
protected override ILogin CreateLogin()
{
return new MyLogin(_userName);
}
//输出Json内容格式
protected override string BuildResponsePack()
{
ResultData resultData = new ResultData()
{
MsgId = actionGetter.GetMsgId(),
ActionId = actionGetter.GetActionId(),
ErrorInfo = "",
Data = new UserData()
{
UserId = Current.UserId,
SessionId = Current.SessionId
}
};
return MathUtils.ToJson(resultData);
}
-
使用聊天中间件,定义MyChatService类继承ChatService
-
定义两个接口协议,3001发送消息,3002聊天列表通知
使用Cocos2d-JS开发客户端,新创建一个"Cocos2d JavaScript Project"项目,选择从现有的资源导入创建项目;如下:
注: 项目中"src/scut"目录是官方提供的SDK,在新项目中可以Copy过去使用; runtime目录下有win平台运行的客户端已编译的版本;
运行效果:
