go get github.com/patrickmn/go-cache

func New(defaultExpiration, cleanupInterval time.Duration) *Cache
func (c *cache) Set(k string, x interface{}, d time.Duration)
func (c *cache) Get(k string) (interface{}, bool)

package main

)
func main() {
    // 设置默认过期时间10秒；清理间隔30分钟
    caching := cache.New(10*time.Second, 30*time.Minute)
    // 设置过期时间
    caching.Set("key", "value", 10*time.Second)
    // 获取数据
    value, ok := caching.Get("key")

        log.Fatal()
    }
    fmt.Printf("value: %v\n", value)
