beego批量上传文件

最近项目中用到beego，需要实现文件批量上传，翻了好久beego的文档都没有找到满意的解决办法，结果看源码时发现作者已经给出了相关实现代码，在源码包controller.go文件中560-586行，记录如下：

//GetFiles return multi-upload files
files, err:=c.GetFiles("myfiles")
	if err != nil {
		http.Error(w, err.Error(), http.StatusNoContent)
		return
	}
for i, _ := range files {
	//for each fileheader, get a handle to the actual file
	file, err := files[i].Open()
	defer file.Close()
	if err != nil {
		http.Error(w, err.Error(), http.StatusInternalServerError)
		return
	}
	//create destination file making sure the path is writeable.
	dst, err := os.Create("upload/" + files[i].Filename)
	defer dst.Close()
	if err != nil {
		http.Error(w, err.Error(), http.StatusInternalServerError)
		return
	}
	//copy the uploaded file to the destination file
	if _, err := io.Copy(dst, file); err != nil {
		http.Error(w, err.Error(), http.StatusInternalServerError)
		return
	}
}

对应的input标签需设置multiple 属性

<input type="file" multiple name="myfiles">
