ASP.NET 核心中的 Redis 缓存

Question

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

Install-Package StackExchange.Redis

但是我无法将它注入和配置到我的服务中，没有 RedisCache 或“AddDistributedRedisCache”方法。

如何注入使用？

Answer 1

01.Download 来自 download 的最新 redis，安装并启动来自 services.msc

的 redis 服务

02.Add project.json

中的两个库

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

03.Add 你在

中进行了依赖注入

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。现在你可以在HomeController.cs

中这样使用

public class HomeController : Controller
{
    private readonly IDistributedCache _distributedCache;
    public HomeController(IDistributedCache distributedCache)
    {
        _distributedCache = distributedCache;
    }
    //Use version Redis 3.22
    //
    public IActionResult Index()
    {
        _distributedCache.SetString("helloFromRedis", "world");
        var valueFromRedis = _distributedCache.GetString("helloFromRedis");
        return View();
    }
 }

Answer 2

我使用了以下解决方案并得到了答案。

1.Download Redis-x64-3.0.504.msi 并安装它 (link)

2.Install Microsoft.Extensions.Caching.StackExchangeRedis 来自 Nuget 包管理器

3.Inside Startup.cs class ，在ConfigureServices方法中，添加这条命令：

 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.In结束：

   [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！！！

Answer 3

Install-Package StackExchange.Redis

Redis 服务：

public class RedisService : IDisposable
{
    private readonly IConnectionMultiplexer Connection;
    private readonly string _connectionString;


    public RedisService(IConfiguration Configuration, ILogger<RedisService> logger)
    {
        _connectionString = Configuration.GetConnectionString("redis connection string");

        var conn = new Lazy<IConnectionMultiplexer>(() => ConnectionMultiplexer.Connect(_connectionString));
        Connection = conn.Value;

        Main = Connection.GetDatabase(1); 


        logger.LogWarning("Redis Service Attached!");

    }

    public IDatabase Main { get; }

   
    
    public void Dispose()
    {
        Connection?.Dispose();
    }
}

在startup.cs

中添加服务

services.AddSingleton<RedisService>();

现在在您的控制器中使用它
