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MarkDown格式: 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。

# description检测

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。

response = requests.get(url=url, params=params, headers=header)
# print("网页编码方式: {} -> {}".format(response.encoding,response.apparent_encoding))
context = response.text.encode(response.encoding).decode(response.apparent_encoding, "ignore")
try:

ret = bs.select('div[id="cnblogs_post_body"] p img')
for item in ret:
try:
img_src_path = item.get("src")
img_src_name = img_src_path.split("/")[-1]
print("[+] 下载图片: {} ".format(img_src_name))
img_download = requests.get(url=img_src_path, headers=header, stream=True)
with open("./image/" + img_src_name, "wb") as fp:
for chunk in img_download.iter_content(chunk_size=1024):
fp.write(chunk)
except Exception:
print("下载图片失败: {}".format(img_src_name))
pass
except Exception:
pass
if __name__ == "__main__":
url = GetURL("backup.xml")
for u in url:
DownloadURLPicture(u)
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https://img2020.cnblogs.com/blog/(.*?)/(.*?)/
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。
对过滤器的进一步优化,使之可以直接过滤出特定的标题,只需要稍微修改一下代码即可,如下代码可实现过滤特定关键词的文章。
