以前有大概介绍过类似的几个不错的通用文件系统工具包，以下是关于spf13/afero 的试用
参考代码
package main
import (
"io/ioutil"
"log"
"github.com/spf13/afero"
)
func main() {
var appFs = afero.NewMemMapFs()
log.Println(appFs.Name())
appFs.Mkdir("/", 0755)
fh, _ := appFs.Create("/demoapp.js")
fh.WriteString("This is a test")
fh.Close()
file, err := appFs.Open("/demoapp.js")
defer file.Close()
if err != nil {
log.Println("open file error:", err.Error())
}
bytes, err := ioutil.ReadAll(file)
if err != nil {
log.Println("read file error:", err.Error())
}
log.Println(string(bytes))
}
集成http server 方法
package main
import (
"io/ioutil"
"log"
"net/http"
"github.com/spf13/afero"
)
func httpFs() {
var appFs = afero.NewMemMapFs()
appFs.Mkdir("/", 0755)
fh, _ := appFs.Create("/demoapp.js")
fh.WriteString("This is a test")
fh.Close()
httpFs := afero.NewHttpFs(appFs)
fileserver := http.FileServer(httpFs.Dir("/"))
http.Handle("/", fileserver)
http.ListenAndServe(":8090", nil)
}
func main() {
httpFs()
}
说明
目前官方也在计划实现一个通用的文件系统，抽象层，比较期待ga，基于通用文件系统的好处是，方便测试，同时屏蔽了
对于多种异构文件系统的访问
