type Cache struct {
	// contains filtered or unexported fields
}

Cache 一个内存缓存库，支持过期和后台更新

func NewCache(size int) (*Cache, error)

NewCache 初始化缓存，缓存数量超过size将使用lru算法淘汰

func (c *Cache) Clean()

Clean 清理所有缓存内容

func (c *Cache) Delete(key string)

Delete 删除指定键缓存

func (c *Cache) Get(key string, loader func() (interface{}, error), expire time.Duration, backgroupUpdate bool) (interface{}, error)

Get 获取key缓存的值，如不存在则使用loader函数加载缓存

如果使用后台更新，函数直接返回过期的值，并使用协程调用loader更新缓存
