如何从python的RFC 2822邮件标题中提取多个电子邮件地址？

如何解决如何从python的RFC 2822邮件标题中提取多个电子邮件地址？

通过所有To行email.utils.getaddresses()：

msg="""To: user1@company1.com, John Doe <user2@example.com>, "Public, John Q." <user3@example.com>
From: anotheruser@user.com
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。

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: user1@company1.com,"User Two" <user2@company2.com","Three,User <user3@company3.com>                               
From: anotheruser@user.com                                                                                                      
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: user1@company1.com,User <user3@company3.com>
$
