  • .Core使用CSRedis

    一、为什么选择CSRedis

    ServiceStack.Redis 是商业版,免费版有限制;

    StackExchange.Redis 是免费版,但是内核在 .NETCore 运行有问题经常 Timeout,暂无法解决;

    CSRedis于2016年开始支持.NETCore一直迭代至今,实现了低门槛、高性能,和分区高级玩法的.NETCore redis-cli SDK;

    在v3.0版本更新中,CSRedis中的所有方法名称进行了调整,使其和redis-cli保持一致,如果你熟悉redis-cli的命令的话,CSRedis可以直接上手,这样学习成本就降低很多。

    二、使用CSRedis

      安装CSRedis

     在appsettings.json做Redis配置

    {
      "Cache": {
        "CacheType": "Redis", //CacheType
        "RedisEndpoint": "127.0.0.1:6379,password=123", //Redis节点地址,定义详见 https://github.com/2881099/csredis
        //如果Redis没有设置密码
        //"RedisEndpoint": "127.0.0.1:6379" //Redis节点地址,定义详见 https://github.com/2881099/csredis
      },
      "AllowedHosts": "*"
    }

    自定义IHostBuilder扩展方法,注入CSRedis服务

    using CSRedis;
    using Microsoft.Extensions.Caching.Distributed;
    using Microsoft.Extensions.Caching.Redis;
    using Microsoft.Extensions.Configuration;
    using Microsoft.Extensions.DependencyInjection;
    using Microsoft.Extensions.Hosting;
    using System;
    
    namespace CSRedisTest
    {
        public static class Extention
        {
            /// <summary>
            /// 使用缓存
            /// </summary>
            /// <param name="hostBuilder">建造者</param>
            /// <returns></returns>
            public static IHostBuilder UseCache(this IHostBuilder hostBuilder)
            {
                hostBuilder.ConfigureServices((buidlerContext, services) =>
                {
                    var cacheOption = buidlerContext.Configuration.GetSection("Cache").Get<CacheOption>();
                    switch (cacheOption.CacheType)
                    {
                        case CacheType.Memory: services.AddDistributedMemoryCache(); break;
                        case CacheType.Redis:
                            {
                                var csredis = new CSRedisClient(cacheOption.RedisEndpoint);
                                RedisHelper.Initialization(csredis);
                                services.AddSingleton(csredis);
                                services.AddSingleton<IDistributedCache>(new CSRedisCache(RedisHelper.Instance));
                            }; break;
                        default: throw new Exception("缓存类型无效");
                    }
                });
    
                return hostBuilder;
            }
        }
    }

    在Program调用该扩展方法

    using Microsoft.AspNetCore.Hosting;
    using Microsoft.Extensions.Hosting;
    
    namespace CSRedisTest
    {
        public class Program
        {
            public static void Main(string[] args)
            {
                CreateHostBuilder(args).Build().Run();
            }
    
            public static IHostBuilder CreateHostBuilder(string[] args) =>
                Host.CreateDefaultBuilder(args)
                    .UseCache()//调动方法
                    .ConfigureWebHostDefaults(webBuilder =>
                    {
                        webBuilder.UseStartup<Startup>();
                    });
        }
    }

    在Controller中使用CSRedis

    using Microsoft.AspNetCore.Mvc;
    using Microsoft.Extensions.Logging;
    using System;
    using System.Collections.Generic;
    using System.Linq;
    
    namespace CSRedisTest.Controllers
    {
        [ApiController]
        [Route("[controller]")]
        public class WeatherForecastController : ControllerBase
        {
            private readonly ILogger<WeatherForecastController> _logger;
    
            public WeatherForecastController(ILogger<WeatherForecastController> logger)
            {
                _logger = logger;
            }
    
            [HttpGet]
            public IEnumerable<WeatherForecast> Get()
            {
                //添加数据 字符串键-值对 
                RedisHelper.Set("hello", "1", 60);//设置过期时间,单位秒
                RedisHelper.Set("world", "2");//默认不过期
    
                // 根据键获取对应的值
                string helloValue=RedisHelper.Get("hello");
    
                // 移除元素
                RedisHelper.Del("world");
    
                var rng = new Random();
                return Enumerable.Range(1, 5).Select(index => new WeatherForecast
                {
                    Date = DateTime.Now.AddDays(index),
                })
                .ToArray();
            }
        }
    }
