如何从python的RFC 2822邮件标题中提取多个电子邮件地址？

问题描述

通过所有To行email.utils.getaddresses()：

msg="""To: [e-mail], John Doe <[e-mail]>, "Public, John Q." <[e-mail]>
From: [e-mail]
Subject: This is a subject

This is the message.
"""

import email

msg822 = email.message_from_string(msg)
for to in email.utils.getaddresses(msg822.get_all("To", [])):
    print("To:",to)

请注意，我改写了你的To电话。我认为您的示例格式无效。

参考：https ://docs.python.org/3/library/email.utils.html#email.utils.getaddresses

解决方法

Python的email模块非常适合解析标头。但是，To:标头可以有多个收件人，并且可能有多个To:标头。那么，如何拆分每个电子邮件地址？我不能在逗号上分开，因为逗号可以被引用。有没有办法做到这一点？

演示代码：

msg="""To: [e-mail],"User Two" <[e-mail]","Three,User <[e-mail]>                               
From: [e-mail]                                                                                                      
Subject: This is a subject

This is the message.                                                                                                            
"""

import email

msg822 = email.message_from_string(msg)
for to in msg822.get_all("To"):
    print("To:",to)

电流输出：

$ python x.py
To: [e-mail],User <[e-mail]>
$
