Question

我是Redis的新手并使用VS 2015和ASP.NET Core应用程序（v 1.0），我安装了nugget包：

Install-Package StackExchange.Redis

但是我无法将其注入并配置到我的服务中，没有 RedisCache 或＆＃34; AddDistributedRedisCache ＆＃34;方法

我如何注射和使用它？

Answer 1

01.从download下载最新的redis，从services.msc安装并启动redis服务

02.在 project.json

中添加两个库

"Microsoft.Extensions.Caching.Redis.Core": "1.0.3",
"Microsoft.AspNetCore.Session": "1.1.0",

03.在

中添加依赖注入

public void ConfigureServices(IServiceCollection services)
    {
        services.AddApplicationInsightsTelemetry(Configuration);

        services.AddMvc();
        //For Redis
        services.AddSession();
        services.AddDistributedRedisCache(options =>
        {
            options.InstanceName = "Sample";
            options.Configuration = "localhost";
        });
  }

并在Configure方法中添加 app.UseMvc 行的顶部

app.UseSession（）;

在asp.net核心的会话存储中使用redis。现在可以在 HomeController.cs

public class HomeController : Controller
{
    private readonly IDistributedCache _distributedCache;
    public HomeController(IDistributedCache distributedCache)
    {
        _distributedCache = distributedCache;
    }
    //Use version Redis 3.22
    //http://stackoverflow.com/questions/35614066/redissessionstateprovider-err-unknown-command-eval
    public IActionResult Index()
    {
        _distributedCache.SetString("helloFromRedis", "world");
        var valueFromRedis = _distributedCache.GetString("helloFromRedis");
        return View();
    }
 }

Answer 2

我使用以下解决方案并获得了答案。

1。下载 Redis-x64-3.0.504.msi 并安装（link）

2。从Nuget Packge Manager安装Microsoft.Extensions.Caching.StackExchangeRedis

3。在Startup.cs类的内部，在ConfigureServices方法中，添加以下命令：

 services.AddStackExchangeRedisCache(options => options.Configuration = "localhost:6379");

将IDistributedCache注入控制器：

 private readonly IDistributedCache _distributedCache;

 public WeatherForecastController( IDistributedCache distributedCache)
 {
     _distributedCache = distributedCache;
 }

5。最后：

   [HttpGet]
    public async Task<List<string>> GetStringItems()
    {
        string cacheKey = "redisCacheKey";
        string serializedStringItems;
        List<string> stringItemsList;

        var encodedStringItems = await _distributedCache.GetAsync(cacheKey);
        if (encodedStringItems != null)
        {
            serializedStringItems = Encoding.UTF8.GetString(encodedStringItems);
            stringItemsList = JsonConvert.DeserializeObject<List<string>>(serializedStringItems);
        }
        else
        {
            stringItemsList = new List<string>() { "John wick", "La La Land", "It" };
            serializedStringItems = JsonConvert.SerializeObject(stringItemsList);
            encodedStringItems = Encoding.UTF8.GetBytes(serializedStringItems);
            var options = new DistributedCacheEntryOptions().SetSlidingExpiration(TimeSpan.FromMinutes(1))
                .SetAbsoluteExpiration(TimeSpan.FromHours(6));
            await _distributedCache.SetAsync(cacheKey, encodedStringItems, options);

        }
        return stringItemsList;
    }

祝你好运！
