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 mainimport ("bytes""fmt""io""io/ioutil""net/http""os""strings")func getImg(url string) (n int64, err error) {path := strings.Split(url, "/")var name stringif len(path) > 1 {name = path[len(path)-1]}fmt.Println(name)out, err := os.Create(name)defer out.Close()resp, err := http.Get(url)defer resp.Body.Close()pix, err := ioutil.ReadAll(resp.Body)n, err = io.Copy(out, bytes.NewReader(pix))return}func main() {getImg("http://img2.bdstatic.com/img/image/166314e251f95cad1c8f496ad547d3e6709c93d5197.jpg")}//该片段来自于http://outofmemory.cn
