golang 下载图片

想用golang下载图片，因为golang和其他语言相比较不用在复制那么多其他的文件。

package main

import (
	"bytes"
	"fmt"
	"io"
	"io/ioutil"
	"net/http"
	"os"
	"strings"
)

func getImg(url string) (n int64, err error) {
	path := (url, "/")
	var name string
	if len(path) > 1 {
		name = path[len(path)-1]
	}
	(name)
	out, err := (name)
	defer ()
	resp, err := (url)
	defer ()
	pix, err := ()
	n, err = (out, (pix))
	return

}
func main() {
	getImg("/img/image/")
}
