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"> </head> <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();

3、Redis封装

配置appsetting.json

Hash
这种存储list数组（适用于三层数据结构，前面两个键最后一个值分别是key、datakey、value）
注意： redisHelp.HashSet("a",str1,str2); "a",str1这两个参数原本有就覆盖
Set
