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: [email protected], "User Two" <[email protected]", "Three, User <[email protected]>
From: [email protected]
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: [email protected], "User Two" <[email protected]", "Three, User <[email protected]>
$
通过所有To行email.utils.getaddresses()：
msg="""To: [email protected], John Doe <[email protected]>, "Public, John Q." <[email protected]>
From: [email protected]
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。
