基于Senparc.CO2NET 缓存策略扩展的缓存使用方法

没啥说的，直接上代码

1、缓存  CacheFactory 实现：

    public class CacheFactory
    {
        /// <summary>
        /// 缓存处理 Redis
        /// </summary>

        public static HashSetCacheModel<T> Cache<T>(string cacheKey, Func<HashSetCacheModel<T>> proc,bool isCache = false, bool refreshCache = false)
        {
            HashSetCacheModel<T> result;
            if (!isCache)
            {
                result = proc();
            }
            else
            {
                IContainerCacheStrategy containerCache = LocalContainerCacheStrategy.Instance;
                IBaseObjectCacheStrategy baseCache = containerCache.BaseCacheStrategy();
                // 缓存
                if (baseCache.CheckExisted(cacheKey)) //判断是否有缓存
                {
                    //已经缓存
                    if (refreshCache)//是否强制刷新缓存
                    {
                        //强制刷新
                        result = proc();
                        baseCache.Update(cacheKey, result);
                    }
                    else
                    {
                        //不强制刷新
                        result = baseCache.Get<HashSetCacheModel<T>>(cacheKey);
                        // 判断是否过期了
                        if (result.ExpireAt < DateTime.Now)
                        {
                            result = proc();
                            baseCache.Update(cacheKey, result);
                        }
                    }
                }
                else
                {
                    // 缓存中没有数据 获取一次存入缓存
                    result = proc();
                    baseCache.Set(cacheKey, result);
                }
            }
            return result;
        }
    }
}

注意：Senparc 底层的Redis使用了HashSet数据结构

2、使用方法：注释里是以前的写法，使用CacheFactory后简化了操作

        /// <summary>
        /// 获取微信用户
        /// </summary>
        /// <param name="weixinAppId"></param>
        /// <param name="openId"></param>
        /// <param name="refresh"></param>
        /// <returns></returns>
        protected WechatUserEntity GetWechatUser(string weixinAppId, string openId, bool refresh = false)
        {
            WechatUserEntity wechatUserEntity = null;
            // 进行缓存
            try
            {
                string cacheKey = "WechatUser:" + weixinAppId + ":" + openId;
                HashSetCacheModel<WechatUserEntity> hashCacheModel= CacheFactory.Cache<WechatUserEntity>(cacheKey, () =>
                {
                    WechatUserManager wechatUserManager = new WechatUserManager();
                    wechatUserEntity = wechatUserManager.GetObjectByWechatAppIdByOpenId(weixinAppId, openId);
                    var cacheModel = new HashSetCacheModel<WechatUserEntity>();
                    cacheModel.CreateOn = DateTime.Now;
                    cacheModel.ExpireAt = DateTime.Now.AddMinutes(10);
                    cacheModel.Value = wechatUserEntity;
                    return cacheModel;
                });
                return hashCacheModel.Value;

                //IContainerCacheStrategy containerCache = LocalContainerCacheStrategy.Instance;
                //IBaseObjectCacheStrategy baseCache = containerCache.BaseCacheStrategy();

                //    {
                //        baseCache.RemoveFromCache(key);
                //    }
                //}
                //if (baseCache.CheckExisted(key))
                //{
                //    cacheModel = baseCache.Get<HashSetCacheModel<WechatUserEntity>>(key);
                //    if (cacheModel.ExpireAt < DateTime.Now)
                //    {
                //        // 过期了，要更新一次

                //        cacheModel.CreateOn = DateTime.Now;
                //        cacheModel.ExpireAt = DateTime.Now.AddMinutes(10);

                //    }
                //    wechatUserEntity = cacheModel.Value;
                //}
                //else

                //}
            }
            catch (Exception ex)
            {
                NLogHelper.Warn(ex, "GetCurrentAutoreplyInfo,weixinAppId=" + weixinAppId);
            }

            return wechatUserEntity;
        }
