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">
