     伟大的博客文章，我找到了我的答案，在这里它是记录的完整解决方案：

   <pre>
    <code>
      // PhotoCreatePOST saves multiple photo uploads
func PhotoCreatePOST(w http.ResponseWriter, r *http.Request) {

err := r.ParseMultipartForm(100000)
    if err != nil {
        fmt.Println("error parsing multiplepart form", err)
        return
    }

files := r.MultipartForm.File["files"]

for i, _ := range files { //Iterate over multiple uploaded files

file, err := files[i].Open()
        defer file.Close()
        if err != nil {
            fmt.Println("error opening file ", err)
            return
        }

ext := path.Ext(files[i].Filename)

//TODO: Verify extension is valid

filename := GetRandomString(10) + ext

//create destination file making sure the path is writeable.
        dst, err := os.Create("media/photos/" + filename)
        defer dst.Close()
        if err != nil {
            fmt.Println("error creating destination ", err)
            return
        }

//copy the uploaded file to the destination file
        if _, err := io.Copy(dst, file); err != nil {
            fmt.Println("error copying file", err)
            return
        }

fmt.Println("Image upload success: ", files[i].Filename)
    }

fmt.Println("all are uploaded")

PhotoCreateGET(w, r)
    return

}

//Generate random filename (never trust user input!)
var letterRunes = []rune("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ123456789")

// GetString returns a random string
func GetRandomString(n int) string {
    rand.Seed(time.Now().UnixNano())
    b := make([]rune, n)
    for i := range b {
        b[i] = letterRunes[rand.Intn(len(letterRunes))]
    }
    return string(b)
}

    <code>
      <form method="post" action="/create/photo" enctype="multipart/form-data">
