python imap：如何解析多部分邮件内容

发布于 2024-09-30 06:03:36 字数 371 浏览 5 评论 0原文

邮件可以包含不同的块，例如：

--0016e68deb06b58acf04897c624e
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable
content_1
...

--0016e68deb06b58acf04897c624e
Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable
content_2
... and so on

如何使用 python 获取每个块的内容？
还有如何获取每个块的属性？（内容类型等）

原文

A mail can contain different blocks like:

--0016e68deb06b58acf04897c624e
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable
content_1
...

--0016e68deb06b58acf04897c624e
Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable
content_2
... and so on

How can I get content of each block with python?
And also how to get properties of each block? (content-type, etc..)

为了解析电子邮件，我使用了 Message.walk() 方法，如下所示：

if msg.is_multipart():
    for part in msg.walk():
        ...

对于内容，您可以尝试：part.get_payload()。对于内容类型，有： part.get_content_type()

您将在这里找到文档：http://docs.python.org/library/email.message.html

您还可以尝试email 模块及其迭代器。

For parsing emails I have used Message.walk() method like this:

if msg.is_multipart():
    for part in msg.walk():
        ...

For content you can try: part.get_payload(). For content-type there is: part.get_content_type()

You will find documetation here: http://docs.python.org/library/email.message.html

You can also try email module with its iterators.

http://docs.python.org/library/email.html

一个非常简单的例子（msg_as_str 包含从 imap 服务器获取的原始字节）：

import email
msg = email.message_from_string(msg_as_str)
print msg["Subject"]

http://docs.python.org/library/email.html

A very simple example (msg_as_str contains the raw bytes you got from the imap server):

import email
msg = email.message_from_string(msg_as_str)
print msg["Subject"]

我已经写了这段代码。如果您喜欢它来解析多部分内容，则可以使用它：

if mime_msg.is_multipart():
        for part in mime_msg.walk():
            if part.is_multipart():
                for subpart in part.get_payload():
                    if subpart.is_multipart():
                        for subsubpart in subpart.get_payload():
                            body = body + str(subsubpart.get_payload(decode=True)) + '\n'
                    else:
                        body = body + str(subpart.get_payload(decode=True)) + '\n'
            else:
                body = body + str(part.get_payload(decode=True)) + '\n'
else:
    body = body + str(mime_msg.get_payload(decode=True)) + '\n'

body = bytes(body,'utf-8').decode('unicode-escape')

如果您想以纯文本形式取出，则将正文转换为 html2text.HTML2Text()

I have wrote this code. You can use it if you like it for parsing multipart content:

if mime_msg.is_multipart():
        for part in mime_msg.walk():
            if part.is_multipart():
                for subpart in part.get_payload():
                    if subpart.is_multipart():
                        for subsubpart in subpart.get_payload():
                            body = body + str(subsubpart.get_payload(decode=True)) + '\n'
                    else:
                        body = body + str(subpart.get_payload(decode=True)) + '\n'
            else:
                body = body + str(part.get_payload(decode=True)) + '\n'
else:
    body = body + str(mime_msg.get_payload(decode=True)) + '\n'

body = bytes(body,'utf-8').decode('unicode-escape')

And if you want to take out in plain text then convert body into html2text.HTML2Text()
