个人实例

1.安装包

EasyCaching.Core
EasyCaching.Redis
这里是以1.4.0为例

2.服务注册

netcore3.0,5.0是在startup，net6是在program设置

builder.Services.AddEasyCaching(option =>
{
    option.UseRedis(t =>
    {
        //43.138.88.44服务器地址，6379端口
        t.DBConfig.Endpoints.Add(new EasyCaching.Core.Configurations.ServerEndPoint("43.138.88.44",6379) );
        //连接那个数据库
        t.DBConfig.Database = 1;
        //数据库密码
        t.DBConfig.Password = "000415";
    });
});

3.使用

Person辅助类

    public class Person
    {
        public string Name { get; set; }
        public string Sex { get; set; }
    }

ValuesController.cs

using EasyCaching.Core;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Newtonsoft.Json;

namespace RedisTest.Controllers
{
    [Route("api/[controller]")]
    [ApiController]
    public class ValuesController : ControllerBase
    {
        private readonly IRedisCachingProvider _redisCachingProvider;
        public ValuesController(IRedisCachingProvider redisCachingProvider)
        {
            _redisCachingProvider = redisCachingProvider;
        }
        [HttpPost]
        [Route("select-cache")]
        public async Task<string>  SelectCache()
        {
            return await _redisCachingProvider.StringGetAsync("name");
        }
        //这里在key不变的情况下，将上面的性别更改了
        [HttpPost]
        [Route("update-cache-sex")]
        public async Task UpdateCache()
        {
            Person person = new Person
            {
                Name = "lty",
                Sex = "woman"
            };
            await _redisCachingProvider.StringSetAsync("name", JsonConvert.SerializeObject(person),
                        TimeSpan.FromMinutes(1));
        }

		//这里在修改了缓存的key，尽管其他没有改变，但是会重新创建一个缓存
        [HttpPost]
        [Route("update-cache-sex-key")]
        public async Task UpdateCacheSexKey()
        {
            Person person = new Person
            {
                Name = "lty",
                Sex = "woman"
            };
            await _redisCachingProvider.StringSetAsync("womanname", JsonConvert.SerializeObject(person),
                        TimeSpan.FromMinutes(1));
        }
        [HttpPost]
        [Route("remove-cache")]
        public async Task RemoveCache()
        {
            Person person = new Person
            {
                Name = "lty",
                Sex = "man"
            };
            await _redisCachingProvider.KeyDelAsync("name");
                       
        }
        [HttpPost]
        [Route("create-cache")]
        public async Task CreateCache()
        {
            Person person = new Person
            {
                Name = "lty",
                Sex = "man"
            };
            await _redisCachingProvider.StringSetAsync("name", JsonConvert.SerializeObject(person),
                        TimeSpan.FromMinutes(1));
        }
    }
}
