C# Redis辅助类封装与简单聊天室的实现思路说明

虽然redis api的功能比较齐全，但个人觉得为了更好的方便学习和使用，还是很有必有做一个类似DBHelper的帮助类

辅助类主要功能(代码会在最后放出来)

1. 事件监听：
	重新配置广播时(主从同步更改)
	发生内部错误时(调试用)
	更改集群时
	配置更改时
	发生错误时
	物理连接失败时
	建立物理连接时

说明：此处只是进行一个简单的监听，请根据实际需要进行修改

2.存储功能:
	a. 【临时存储】直接 key - value string 类型存储 使用StringXxx方法进行调用
		此类方法用于存储一些临时的、但会被频繁请求到的数据

	b.【永久存储】使用 key - filed - value 类型存储 使用HashXxx方法进行调用
		此类方法存储的是一个类似键值对对象，不必设置有效期，可用于存储一些配置信息

3.消息队列
	【永久存储】 通过push/pop进行消息的读取与存储，可根据实际应用场景制定

4.发布/订阅
	【不进行存储】
	是类似一种即时通讯的功能，可根据实际应用场景制定

为了加深对于redis的使用，就弄了一个简单的通讯功能，这里说下主要的实现思路:

登录时

需要保存用户信息(永久)且设置登录时效(短暂)
a.使用Hash相关方法 添加 用户标识(filed) - Guid(value) key(固定)
b.使用StringXxx相关方法 添加 用户对应的Guid标识 - 固定值 并设置有效时长 

公共聊天室

a.使用Hash相关方法 获取所有Value 获取已登录的用户列表 (由于key 固定 ，每个登录用户获取的都会是同一份列表数据)
b.聊天室实现 (渠道固定+发布订阅)
  事件
	发送消息>
		将消息发布至聊天室渠道
	接收消息>
		订阅聊天室渠道，并将接收的消息显示至消息面板

私聊

a.使用登录用户 与 私聊对象作为参数，生成唯一标识(此处采用md5) 
b.使用唯一标识作为聊天渠道进行发布/订阅 进行单人聊天

细节说明

添加提醒相关的发布/订阅(不同提醒根据消息类型进行区分)
  a.登录/退出相关
	1.登录提醒:登录后发布登录提醒，通知其他已登录用户更新已登录用户列表
	2.退出提醒:与1类型
  b.私聊处理
	1.当私聊时发布消息，收到的订阅数为1时(即只有自己订阅了消息),需要将消息添加到消息队列中(使用私聊的唯一标识作为key),并添加一条私聊提示信息，将私聊对象的用户标识作为内容关键字
	2.当在聊天室收到与自己标识相匹配私聊提醒消息时，进行相应提醒
	3.在进入聊天室时，通过生成的标识码，去消息队列获取未读消息并进行显示。

《接口(实现根据场景自己实现吧:) 我是使用Newtonsoft.Json简单的实现了一下)》

public interface IJsonDeal
{

    string Serialize(object obj);

    T Deserialize<T>(string jsonDate);

}
