go-cache是Go语言实现的一个内存中的缓存框架，实现Key-Value的序列存储。
示例代码：
import "github.com/pmylund/go-cache"// Create a cache with a default expiration time of 5 minutes, and which// purges expired items every 30 secondsc := cache.New(5*time.Minute, 30*time.Second)// Set the value of the key "foo" to "bar", with the default expiration timec.Set("foo", "bar", 0)// Set the value of the key "baz" to "yes", with no expiration time// (the item won't be removed until it is re-set, or removed using// c.Delete("baz")c.Set("baz", "yes", -1)// Get the string associated with the key "foo" from the cachefoo, found := c.Get("foo")if found { fmt.Println(foo)}
