golang文件服务器的两种方式(可以访问任何目录)

package main

import (
  "fmt"
  "net/http"
)

func main() {
  http.Handle("/", http.FileServer(http.Dir("./")))

  e := http.ListenAndServe(":8080", nil)
  fmt.Println(e)
}

package main

import (
  "fmt"
  "net/http"
)

func main() {
  mux := http.NewServeMux()
  mux.Handle("/", http.StripPrefix("/", http.FileServer(http.Dir("/"))))
  mux.Handle("/c/", http.StripPrefix("/c/", http.FileServer(http.Dir("c:"))))
  mux.Handle("/d/", http.StripPrefix("/d/", http.FileServer(http.Dir("d:"))))
  mux.Handle("/e/", http.StripPrefix("/e/", http.FileServer(http.Dir("e:"))))
  if err := http.ListenAndServe(":3008", mux); err != nil {
    log.Fatal(err)
  }
}

package main

import (
 "fmt"
 "net/http"
 "os"
 "path/filepath"
)

func main() {
 p, _ := filepath.Abs(filepath.Dir(os.Args[0]))
 http.Handle("/", http.FileServer(http.Dir(p)))
 err := http.ListenAndServe(":8088", nil)
 if err != nil {
 fmt.Println(err)
 }
}
