CacheFs 缓存文件系统
通过比较修改时间,在Open和Read时如果没有修改,减少系统调用(具体是避免os.Open,(*os.File).Read)
type HttpCacheFs ¶
type HttpCacheFs struct {
// contains filtered or unexported fields
}
HttpCacheFs Http缓存文件系统
Example ¶
path := "path" http.Handle("/", http.FileServer(NewHttpCacheFs(path)))
Output:
func NewHttpCacheFs ¶
func NewHttpCacheFs(path string) *HttpCacheFs
NewHttpCacheFs 创建NewHttpCacheFs
- path 是相对的路径 相当于 http.Dir
func (*HttpCacheFs) Open ¶
func (fs *HttpCacheFs) Open(name string) (http.File, error)
Open 实现 http.FileSystem 接口
