基于python的extract_msg模块提取outlook邮箱保存的msg⽂件中的附件
笔者保存了⼀些outlook邮箱中保存的⼀些msg格式的邮件⽂件，现需要将其中的附件提取出来，
当然直接在outlook中就可以另存附件，但outlook默认是不⽀持批量提取邮件中的附件的
思考过⼏种⽅案，其中之⼀就是使⽤python编程语⾔下的extract_msg模块，记录如下
1、安装extract_msg模块pip install extract-msg，笔者写此随笔时，最新版本为extract-msg 0.27.4
陶瓷彩绘2、安装后，最简单的使⽤，直接在命令⾏⼀条命令，即可将msg中的⽂件解压到当前⽬录下的⼀个⼦⽬录中（⽬录名与邮件信息有关）
#会在当前⽬录下，⽣成⼀个⽬录，然后将msg邮件⽂件中的附件和解压到其中
python -m extract_msg qq_5201351.msg
3、在py⽂件中，可以使⽤如下⽅法只提取其中的附件(需要先创建要保存附件的⽬录)：
import extract_msg
msg = extract_msg.Message("qq_5201351.msg")
msg_attachment = msg.attachments
if msg_attachment:车牌号英文
for attachment in msg_attachment:
attachment.save(customPath="./qq_5201351_dir")
++++++未解决的问题>>>>：
1、使⽤上⾯的⽅法对于⼤多数msg都能够正常提取出附件，或者邮件内容，但是笔者有的mgs提取时会报如下错误，
⽬录未找到解决⽅法，如有找到解决⽅法的，欢迎下⽅留⾔，⾮常感谢！
