篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了在ASP.NET WebAPI 中使用缓存Redis相关的知识,希望对你有一定的参考价值。
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());
