(精华)2020年7月20日 ASP.NET Core CSRedisCore的使用

首先安装如下包

Install-Package Caching.CSRedis
Install-Package CSRedisCore
Install-Package Microsoft.Extensions.Caching.Memory

/// <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;
}

class CacheOption
{
    public CacheType CacheType { get; set; }
    public string RedisEndpoint { get; set; }
}

public class Program
{
    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .UseIdHelper()//分布式自增Id组件
            .UseLog()//使用serilog日志框架
            .UseCache()//使用CSRedisCore缓存
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
            });
}

使用

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Caching.Distributed;
using Microsoft.Extensions.Logging;

namespace CORE.WEBERP.Controllers
{
    [ApiController]
    [Route("[controller]")]
    public class WeatherForecastController : ControllerBase
    {
        private static readonly string[] Summaries = new[]
        {
            "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
        };

        private readonly ILogger<WeatherForecastController> _logger;
        readonly IDistributedCache _cache;

        public WeatherForecastController(ILogger<WeatherForecastController> logger, IDistributedCache cache)
        {
            _logger = logger;
            _cache = cache;
        }

        [HttpGet]
        public IEnumerable<WeatherForecast> Get()
        {
            //缓存
            _cache.SetStringAsync("redis测试", "123456ask");
            //取缓存
            string key=_cache.GetStringAsync("redis测试").ToString();
            var rng = new Random();
            return Enumerable.Range(1, 5).Select(index => new WeatherForecast
            {
                Date = DateTime.Now.AddDays(index),
                TemperatureC = rng.Next(-20, 55),
                Summary = Summaries[rng.Next(Summaries.Length)]
            })
            .ToArray();
        }
    }
}

备注：其他函数请移到类库中去查看，本人博客里都有。
