防止使用Golang服务器访问文件夹中的文件 [英] prevent access to files in folder with a golang server

问题描述

我在golang中有一台服务器，它可以像这样处理文件夹路径:

I've a server in golang who handle folder path like that :

fs := http.FileServer(http.Dir("./assets"))
http.Handle("/Images/", fs)
http.ListenAndServe(":8000", nil)

但是在此文件夹中有私人图像，因此不应访问文件.因此，如何保护图像访问并防止任何人访问文件夹的内容.

But in this folder there are privates images, and it shouldn't be possible to access files. So how can i secure image access and prevent anybody to access content of folder.

推荐答案

如果您想使用 http 包阻止目录，那么这可能对您有用:

If you want to block a directory using http package, maybe this will be useful to you :

package main

import (
  "net/http"
  "os"
)

type justFilesFilesystem struct {
  fs http.FileSystem
}

func (fs justFilesFilesystem) Open(name string) (http.File, error) {
  f, err := fs.fs.Open(name)
  if err != nil {
      return nil, err
  }
  return neuteredReaddirFile{f}, nil
}

type neuteredReaddirFile struct {
  http.File
}

func (f neuteredReaddirFile) Readdir(count int) ([]os.FileInfo, error) {
  return nil, nil
}

func main() {
  fs := justFilesFilesystem{http.Dir("/tmp/")}
  http.ListenAndServe(":8080", http.FileServer(fs))
}
