基础使用初步看了下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
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(intid) { returnDateTime.Now.ToString(); }
Etag头
客户端使用StackExchange.Redis，
Install-Package StackExchange.Redis.StrongName
在Autofac中注册Redis连接
var builder = newContainerBuilder(); //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 => { returnConnectionMultiplexer.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 classRedisService : IRedisService { private static readonly Logger logger =LogManager.GetCurrentClassLogger(); /// <summary> ///Redis服务 /// </summary> private readonlyConnectionMultiplexer _connectionMultiplexer; /// <summary> ///构造函数 /// </summary> /// <param name="connectionMultiplexer">Redis服务</param> publicRedisService(ConnectionMultiplexer connectionMultiplexer) { _connectionMultiplexer =connectionMultiplexer; } /// <summary> ///根据KEY获得值 /// </summary> /// <param name="key">key</param> /// <returns></returns> public async Task<WebAPIResponse> Get(stringkey) { try { var db =_connectionMultiplexer.GetDatabase(); /* var set = await db.StringSetAsync("name", "irving"); var get = await db.StringGetAsync("name"); */ return newWebAPIResponse { IsError = false, Msg = string.Empty, Data = awaitdb.StringGetAsync(key) }; } catch(Exception ex) { logger.Error(ex, "RedisService Get Exception : " +ex.Message); return newWebAPIResponse { IsError = false, Msg = string.Empty, Data = string.Empty }; } } }
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 interfaceIApiOutputCache { T Get<T>(string key) where T : class; object Get(stringkey); void Remove(stringkey); void RemoveStartsWith(stringkey); bool Contains(stringkey); void Add(string key, object o, DateTimeOffset expiration, string dependsOnKey = null); }
实现服务
/// <summary> ///实现Redis服务 /// </summary> public classRedisCacheProvider : IApiOutputCache { /// <summary> ///Redis服务 /// </summary> private readonlyConnectionMultiplexer _connectionMultiplexer; /// <summary> ///构造函数 /// </summary> /// <param name="connectionMultiplexer">Redis服务</param> publicRedisCacheProvider(ConnectionMultiplexer connectionMultiplexer) { _connectionMultiplexer =connectionMultiplexer; } public void Add(string key, object o, DateTimeOffset expiration, string dependsOnKey = null) { throw newNotImplementedException(); } public IEnumerable<string>AllKeys { get { throw newNotImplementedException(); } } public bool Contains(stringkey) { throw newNotImplementedException(); } public object Get(stringkey) { var db =_connectionMultiplexer.GetDatabase(); returndb.StringGet(key); } public T Get<T>(string key) where T : class { throw newNotImplementedException(); } public void Remove(stringkey) { throw newNotImplementedException(); } public void RemoveStartsWith(stringkey) { throw newNotImplementedException(); } }
注册WebAPIConfig
configuration.CacheOutputConfiguration().RegisterCacheOutputProvider(() => RedisCacheProvider);
或者使用Autofac for Web API
var builder = newContainerBuilder(); builder.RegisterInstance(newRedisCacheProvider()); config.DependencyResolver = new AutofacWebApiDependencyResolver(builder.Build());
