初步看了下CacheCow与OutputCache，感觉还是CacheOutput比较符合自己的要求，使用也很简单

PM>Install-Package Strathweb.CacheOutput.WebApi2

基础使用

CacheOutput特性

        [Route("get")]
        [CacheOutput(ClientTimeSpan = 60, ServerTimeSpan = 60)]
        public IEnumerable<string> Get()
        {
            return new string[] { "Tom", "Irving" };
        }

以参数为key

        [Route("get")]
        [CacheOutput(ServerTimeSpan = 50, ExcludeQueryStringFromCacheKey = true)]
        public string Get(int id)
        {
            return DateTime.Now.ToString();
        }

Etag头

使用Redis

客户端使用StackExchange.Redis，Install-Package StackExchange.Redis.StrongName


在Autofac中注册Redis连接

          var builder = new ContainerBuilder();
            //注册api容器的实现
            builder.RegisterApiControllers(Assembly.GetExecutingAssembly());
            //注册mvc容器的实现
            // builder.RegisterControllers(Assembly.GetExecutingAssembly());
            //在Autofac中注册Redis的连接，并设置为Singleton
            builder.Register(r =>
            {
                return ConnectionMultiplexer.Connect(DBSetting.Redis);
            }).AsSelf().SingleInstance();
            var container = builder.Build();
            GlobalConfiguration.Configuration.DependencyResolver = new AutofacWebApiDependencyResolver(container);

通过构造注入即可

/// <summary>
    ///Redis服务
    /// </summary>
    public class RedisService : IRedisService
    {
        private static readonly Logger logger = LogManager.GetCurrentClassLogger();

        /// <summary>
        ///Redis服务
        /// </summary>
        private readonly ConnectionMultiplexer _connectionMultiplexer;

        /// <summary>
        /// 构造函数
        /// </summary>
        /// <param name="connectionMultiplexer">Redis服务</param>
        public RedisService(ConnectionMultiplexer connectionMultiplexer)
        {
            _connectionMultiplexer = connectionMultiplexer;
        }

        /// <summary>
        /// 根据KEY获得值
        /// </summary>
        /// <param name="key">key</param>
        /// <returns></returns>
        public async Task<WebAPIResponse> Get(string key)
        {
            try
            {
                var db = _connectionMultiplexer.GetDatabase();
               /*
               var set = await db.StringSetAsync("name", "irving");
               var get = await db.StringGetAsync("name");
               */
                return new WebAPIResponse
                {
                    IsError = false,
                    Msg = string.Empty,
                    Data = await db.StringGetAsync(key)
                };
            }
            catch (Exception ex)
            {
                logger.Error(ex, "RedisService Get Exception : " + ex.Message);
                return new WebAPIResponse
               {
                   IsError = false,
                   Msg = string.Empty,
                   Data = string.Empty
               };
            }
        }
    }

CacheOutput与Redis

默认CacheOutput使用System.Runtime.Caching.MemoryCache来缓存数据，可以自定义扩展到DB,Memcached,Redis等;只需要实现IApiOutputCache接口

public interface IApiOutputCache
{
    T Get<T>(string key) where T : class;
    object Get(string key);
    void Remove(string key);
    void RemoveStartsWith(string key);
    bool Contains(string key);
    void Add(string key, object o, DateTimeOffset expiration, string dependsOnKey = null);
}

实现服务

/// <summary>
    /// 实现Redis服务
    /// </summary>
    public class RedisCacheProvider : IApiOutputCache
    {
        /// <summary>
        ///Redis服务
        /// </summary>
        private readonly ConnectionMultiplexer _connectionMultiplexer;

        /// <summary>
        /// 构造函数
        /// </summary>
        /// <param name="connectionMultiplexer">Redis服务</param>
        public RedisCacheProvider(ConnectionMultiplexer connectionMultiplexer)
        {
            _connectionMultiplexer = connectionMultiplexer;
        }

        public void Add(string key, object o, DateTimeOffset expiration, string dependsOnKey = null)
        {
            throw new NotImplementedException();
        }

        public IEnumerable<string> AllKeys
        {
            get { throw new NotImplementedException(); }
        }

        public bool Contains(string key)
        {
            throw new NotImplementedException();
        }

        public object Get(string key)
        {
            var db = _connectionMultiplexer.GetDatabase();
            return db.StringGet(key);
        }

        public T Get<T>(string key) where T : class
        {
            throw new NotImplementedException();
        }

        public void Remove(string key)
        {
            throw new NotImplementedException();
        }

        public void RemoveStartsWith(string key)
        {
            throw new NotImplementedException();
        }
    }

注册WebAPIConfig

configuration.CacheOutputConfiguration().RegisterCacheOutputProvider(() => RedisCacheProvider);

或者使用Autofac for Web API

var builder = new ContainerBuilder();
builder.RegisterInstance(new RedisCacheProvider());
config.DependencyResolver = new AutofacWebApiDependencyResolver(builder.Build());
