用python写个博客迁移工具

请自行替换user_name与blog_id
// 下载单篇文章到默认目录'./cnblogs' 并输出日志到'./log'
python3 main.py -m download -a https://www.cnblogs.com/{{user_name}}/p/{{blog_id}}.html --enable_log 

// 下载用户所有文章到目录'/Users/cnblogs_t'
python3 main.py -m download -u https://www.cnblogs.com/{{username}} -p /Users/cnblogs_t

// 上传单篇文章到掘金草稿箱
python3 main.py -m upload -f ./cnblogs/{{blog_id}}.html

// 上传'./test_blogs'下所有的html文件到掘金草稿箱
python3 main.py -m upload -d ./test_blogs
