在.Net中操作redis

在.Net中操作redis

一、环境

• .Net 7
• redis 7.2.4

二、所需类包

• StackExchange.Redis

三、连接redis信息

appsettings.json配置redis连接信息

 // Redis配置
 //"Redis": {
 //  "Default": {
 //    "Connection": "", // 连接地址，端口号，密码
 //    "InstanceName": "", // 实例名
 //    "DefaultDB": "1" // 数据库
 //  }
 //},

 "Redis": {
   "Host": "120.xxx.xx.xx", // ip地址
   "Port": "6379", // 端口
   "password": "123456", // redis密码
   "InstanceName": "local", // 实例名称
   "DefaultDb": 1, // 连接的库
   "maxWritePoolSize": 60,
   "maxReadPoolSize": 60,
   "autoStart": true,
   "ConnectTimeout": 60, // 超时
   "KeepAlive": 5, // 保存x秒的活动连接
   "recordeLog": false, 
   "preName": "test_" // key的前缀
 },

四、实例

using AspNetFrame.Domain.Entity.User;
using AspNetFrame.Domain.Service;
using Microsoft.AspNetCore.Mvc;
using Newtonsoft.Json;
using StackExchange.Redis;
using System.Security.Policy;
using System;

namespace AspNetFrame.Api.Controller.Redis
{
    [ApiController]
    [Route("[controller]/[action]")]
    public class RedisCnnTestController : ControllerBase
    {
        private readonly IConfiguration _configuration;
        private IDatabase cache;
        private ConnectionMultiplexer connection;
        public RedisCnnTestController(IConfiguration configuration) 
        {
            _configuration = configuration;
            string redisHost = _configuration["Redis:host"]; // 连接的url
            int redisPort = int.Parse(_configuration["Redis:port"]); // 端口
            string Password =_configuration["Redis:Password"]; // 连接密码
            int DefaultDatabase = int.Parse(_configuration["Redis:DefaultDb"]); // 数据库
            int ConnectTimeout = int.Parse(_configuration["Redis:ConnectTimeout"]); // 超时时间
            int KeepAlive = int.Parse(_configuration["Redis:KeepAlive"]); // 保存x秒的活动连接

            // 连接配置
            var configurationOptions = new ConfigurationOptions
            {
                EndPoints =
                {
                    { redisHost, redisPort },
                },
                DefaultDatabase = DefaultDatabase,
                KeepAlive = KeepAlive, // 保存x秒的活动连接
                Password = Password, // 连接密码
                ConnectTimeout = ConnectTimeout, //超时时间
                AllowAdmin = true,
            };
            connection = ConnectionMultiplexer.Connect(configurationOptions);
            cache = connection.GetDatabase();
        }
        public JsonResult Test()
        {
            //string redisHost = _configuration["Redis:host"]; // 连接的url
            //int redisPort = int.Parse(_configuration["Redis:port"]); // 端口
            //string pwd = _configuration["Redis:Password"];

            cache.StringSet("test", "hello");
            string test = cache.StringGet("test");
            JsonResult json = new JsonResult(new
            {
                code = 200,
                msg = test
            });
            return json;
        }

        [HttpPost]
        public JsonResult Test2()
        {
            LoginUser loginUser = new LoginUser()
            {
                UserName = "admin",
                Password = "admin",
                AuthorityId = 1,
            };

            LoginUser loginUser2 = new LoginUser()
            {
                UserName = "admin2",
                Password = "admin2",
                AuthorityId = 1,
            };


            List<LoginUser> loginUsers = new List<LoginUser>() { loginUser, loginUser2 };
            cache.StringSet("loginUserList", JsonConvert.SerializeObject(loginUsers), TimeSpan.FromMinutes(10));  // 过期时间为10分钟
            cache.StringSet("loginUser_admin", JsonConvert.SerializeObject(loginUser), TimeSpan.FromMinutes(10)); 
            cache.StringSet("test", "hello");

            LoginUser redisLoginUser = JsonConvert.DeserializeObject<LoginUser>(cache.StringGet("loginUser_admin"));

            string test = cache.StringGet("test");
            JsonResult json = new JsonResult(new
            {
                code = 200,
                msg = test,
                result= redisLoginUser
            });
            return json;
        }
    }
}

五、调用api结果

可视化工具:Another Redis Desktop Manager
redis中数据

这样就把list数据存入了redis中
