本文针对博客园实现了一个自动备份脚本，可以快速将自己的文章备份成Markdown格式的独立文件，备份后的md文件可以直接放入到hexo博客中，感兴趣的可以了解一下

鉴于有些小伙伴在寻找博客园迁移到个人博客的方案，本人针对博客园实现了一个自动备份脚本，可以快速将博客园中自己的文章备份成Markdown格式的独立文件，备份后的md文件可以直接放入到hexo博客中，快速生成自己的站点，而不需要自己逐篇文章迁移，提高了备份文章的效率。

首先第一步将博客园主题替换为codinglife默认主题，第二步登录到自己的博客园后台，然后选择博客备份，备份所有的随笔文章，如下所示：

 

备份出来以后将其命名为backup.xml，然后新建一个main.py脚本，以及一个blog目录，代码实现的原理是，解析xml格式并依次提取出文档内容，然后分别保存为markdown文件。

 

转存文章到MD

写入备份脚本，代码如下所示，运行后即可自动转存文件到blog目录下，当运行结束后备份也就结束了。

                f.close()

        except Exception:

            pass

    GetMarkDown("backup.xml")

备份后的效果如下所示：

 

打开Markdown格式看一下，此处的标签和分类使用了一个别名，在备份下来以后，你可以逐个区域进行替换，将其替换成自己需要的分类类型即可。

 

转存图片到本地

接着就是继续循环将博客中所有图片备份下来，同样新建一个image文件夹，并运行如下代码实现备份。

备份后的效果如下：

 

替换文章内的图片链接地址，可以使用编辑器，启用正则批量替换。

 

当把博客备份下来以后你就可以把这些文章拷贝到hexo博客_post目录下面，然后hexo命令快速渲染生成博客园的镜像站点，这样也算是增加双保险了。
