How to receive mail using python
提问by Matthew Downey
I would like to receive email using python. So far I have been able to get the subject but not the body. Here is the code I have been using:
我想使用 python 接收电子邮件。到目前为止，我已经能够得到主题，但不能得到身体。这是我一直在使用的代码：
import poplib
from email import parser
pop_conn = poplib.POP3_SSL('pop.gmail.com')
pop_conn.user('myusername')
pop_conn.pass_('mypassword')
#Get messages from server:
messages = [pop_conn.retr(i) for i in range(1, len(pop_conn.list()[1]) + 1)]
# Concat message pieces:
messages = ["\n".join(mssg[1]) for mssg in messages]
#Parse message intom an email object:
messages = [parser.Parser().parsestr(mssg) for mssg in messages]
for message in messages:
print message['subject']
print message['body']
pop_conn.quit()
My issue is that when I run this code it properly returns the Subject but not the body. So if I send an email with the subject "Tester" and the body "This is a test message" it looks like this in IDLE.
我的问题是，当我运行此代码时，它会正确返回主题而不是正文。因此，如果我发送主题为“Tester”且正文为“This is a test message”的电子邮件，它在 IDLE 中看起来像这样。
>>>>Tester >>>>None
So it appears to be accurately assessing the subject but not the body, I think it is in the parsing method right? The issue is that I don't know enough about these libraries to figure out how to change it so that it returns both a subject and a body.
所以它似乎准确地评估了主题而不是身体，我认为它在解析方法中对吗？问题是我对这些库知之甚少，无法弄清楚如何更改它以便它同时返回主题和正文。

The email parser returns an email.message.Messageobject, which does not contain a bodykey, as you'll see if you run
电子邮件解析器返回一个email.message.Message对象，该对象不包含body密钥，您将在运行时看到
print message.keys()
What you want is the get_payload()method:
你想要的是get_payload()方法：
for message in messages:
print message['subject']
print message.get_payload()
pop_conn.quit()
But this gets complicated when it comes to multi-part messages; get_payload()returns a list of parts, each of which is a Messageobject. You can get a particular part of the multipart message by using get_payload(i), which returns the ith part, raises an IndexErrorif iis out of range, or raises a TypeErrorif the message is not multipart.
但是当涉及到多部分消息时，这会变得复杂；get_payload()返回一个部件列表，每个部件都是一个Message对象。您可以使用 获取多部分消息的特定部分get_payload(i)，它返回第ith 部分，引发IndexErrorifi超出范围，或引发 aTypeError如果消息不是多部分。
As Gustavo Costa De Oliveir points out, you can use the walk()method to get the parts in order -- it does a depth-first traversal of the parts and subparts of the message.
正如 Gustavo Costa De Oliveir 指出的那样，您可以使用该walk()方法按顺序获取部分——它对消息的部分和子部分进行深度优先遍历。
There's more about the email.parsermodule at http://docs.python.org/library/email.message.html#email.message.Message.

The object message does not have a body, you will need to parse the multiple parts, like this:
对象消息没有正文，您需要解析多个部分，如下所示：
for part in message.walk():
if part.get_content_type():
body = part.get_payload(decode=True)
The walk()function iterates depth-first through the parts of the email, and you are looking for the parts that have a content-type. The content types can be either text/plainor text/html, and sometimes one e-mail can contain both (if the message content_typeis set to multipart/alternative).
该walk()函数通过电子邮件的各个部分迭代深度优先，并且您正在寻找具有内容类型的部分。内容类型可以是text/plain或text/html，有时一封电子邮件可以包含两者（如果邮件content_type设置为multipart/alternative）。

it also good return data in correct encoding in message contains some multilingual content
它也很好地返回消息中正确编码的数据包含一些多语言内容
charset = part.get_content_charset()
content = part.get_payload(decode=True)
content = content.decode(charset).encode('utf-8')

if u want to use IMAP4. Use outlook python library, download here : https://github.com/awangga/outlookto retrieve unread email from your inbox :
如果你想使用 IMAP4。使用 Outlook python 库，在此处下载：https: //github.com/awangga/outlook从收件箱中检索未读电子邮件：
import outlook
mail = outlook.Outlook()
mail.login('[email protected]','yourpassword')
mail.inbox()
print mail.unread()
to retrive email element :
检索电子邮件元素：
print mail.mailbody()
print mail.mailsubject()
print mail.mailfrom()
print mail.mailto()
