一、前端客服代码

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>LayIM测试</title>
<link rel="stylesheet" href="./layui/css/layui.css" media="all">
<link rel="stylesheet" href="./contextMenu/contextMenu.css">

<body>
<script src="./layui/layui.js"></script>
<script>
    layui.config({
      base: './contextMenu/' //扩展 JS 所在目录
      ,version: true
    }).extend({
      ext: 'contextMenu'
    });
    //演示代码
    layui.use('layim', function(layim){
      var layim = layui.layim;
      layim.config({
        init: {
          //配置客户信息
          mine: {
            "username": "访客" //我的昵称
            ,"id": "100000123" //我的ID
            ,"status": "online" //在线状态 online：在线、hide：隐身
            ,"remark": "在深邃的编码世界，做一枚轻盈的纸飞机" //我的签名
            ,"avatar": "//res.layui.com/images/fly/avatar/00.jpg" //我的头像
          }
        }
        //开启客服模式
        ,brief: true
      });
      //打开一个客服面板
      layim.chat({
        name: '在线客服一' //名称
        ,type: 'kefu' //聊天类型
        ,avatar: '//tp1.sinaimg.cn/5619439268/180/40030060651/1' //头像
        ,id: 1111111 //定义唯一的id方便你处理信息
      }).chat({
        name: '在线客服二' //名称
        ,type: 'kefu' //聊天类型
        ,avatar: '//tp1.sinaimg.cn/5619439268/180/40030060651/1' //头像
        ,id: 2222222 //定义唯一的id方便你处理信息
      });
      layim.setChatMin(); //收缩聊天面板
    });    
</script>
</body>
</html>

二、在.Net Core 2.1中使用

1、安装依赖包：Nugget: StackExchange.Redis

2、新建Helper类库，并添加RedisHelper.cs类

    public class RedisHelper
    {
        private ConnectionMultiplexer Redis { get; set; }
        private IDatabase DB { get; set; }
        public RedisHelper(string connection)
        {
            Redis = ConnectionMultiplexer.Connect(connection);
            DB = Redis.GetDatabase();
        }

        /// <summary>
        /// 增加/修改
        /// </summary>
        /// <param name="key"></param>
        /// <param name="value"></param>
        /// <returns></returns>
        public bool SetValue(string key, string value)
        {
            return DB.StringSet(key, value);
        }

        /// <summary>
        /// 查询
        /// </summary>
        /// <param name="key"></param>
        /// <returns></returns>
        public string GetValue(string key)
        {
            return DB.StringGet(key);
        }

        /// <summary>
        /// 删除
        /// </summary>
        /// <param name="key"></param>
        /// <returns></returns>
        public bool DeleteKey(string key)
        {
            return DB.KeyDelete(key);
        }
    }

3、使用

        RedisHelper redisHelper = new RedisHelper("127.0.0.1:6379");
        string value = "测试数据";
        bool testValue = redisHelper.SetValue("key", value);
        string saveValue = redisHelper.GetValue("key");

        Console.WriteLine(saveValue);

        bool newValue = redisHelper.SetValue("key", "NewValue");
        saveValue = redisHelper.GetValue("key");

        Console.WriteLine(saveValue);

        bool deleteKey = redisHelper.DeleteKey("key");
        string empty = redisHelper.GetValue("key");

        Console.WriteLine(empty);

        Console.ReadKey();

using StackExchange.Redis;

using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Text;
using System.Threading.Tasks;

        private int DbNum { get; set; }
        private readonly ConnectionMultiplexer _conn;
        public string CustomKey;

        #region 构造函数

        public RedisHelper(int dbNum = 0)
            : this(dbNum, null)
        {
        }

        public RedisHelper(int dbNum, string readWriteHosts)
        {
            DbNum = dbNum;
            _conn =
                string.IsNullOrWhiteSpace(readWriteHosts) ?
                RedisConnectionHelp.Instance :
                RedisConnectionHelp.GetConnectionMultiplexer(readWriteHosts);
        }
