Python Message' Object Has No Attribute 'Get_Body

Question

I'm trying to search email body but facing some issues:

 #!/usr/local/bin/python3
from email.message import EmailMessage
import email
import imaplib
import re
import sys
import logging
import base64
import os
logging.basicConfig(stream=sys.stdout, level=logging.INFO)

###########log in to mailbox########################
user = ''
pwd = 'pwd'

conn = imaplib.IMAP4_SSL("outlook.office365.com")
conn.login(user,pwd)
conn.select("test")
count = conn.select("test")

resp, items = conn.uid("search" ,None, '(OR (FROM "some@email) (FROM "some@email"))')

items = items[0].split()
for emailid in items:
    resp, data = conn.uid("fetch",emailid, "(RFC822)")
    if resp == 'OK':
        email_body = data[0][1]#.decode('utf-8')
        mail = email.message_from_bytes(email_body)

        #get all emails with words "PA1" or "PA2" in subject
        if mail["Subject"].find("PA1") > 0 or mail["Subject"].find("PA2") > 0:
           print (mail)

I have issues in following line:

body = mail.get_body(preferencelist=('plain', 'html'))

getting:

AttributeError: 'Message' object has no attribute 'get_body'

To address the message:

AttributeError: 'Message' object has no attribute 'get_body'

When creating the Message object you need to specify a policy or you get the default email.policy.Compat32 policy. get_body() and several other methods did not exist in Python 3.2.

The line creating the mail object should be:

mail = email.message_from_bytes(data, policy=email.policy.default)

You should not convert the MIME structure to a string and then feed that to message_from_string. Instead, keep it as a bytes object.

from email.policy import default as default_policy
...
items = items[0].split()
for emailid in items:
    resp, data = conn.uid("fetch",emailid, "(RFC822)")
    if resp == 'OK':
        email_blob = data[0][1]
        mail = email.message_from_bytes(email_blob, policy=default_policy)
        if not any(x in mail['subject'] for x in ('PA1', 'PA2')):
            continue

You are not showing how you are traversing the MIME structure so I sort of assume you are currently not doing that at all. Probably you want something like

        # continuation for the above code
        body = mail.get_body(preferencelist=('plain', 'html'))
        for lines in body.split('\n'):
            if line.startswith('MACHINE:'):
                result = line[8:].strip()
                break

It looks like you have an email body part encoded using Content-Transfer-Encoding: quoted-printable. The above code is robust against various encodings because the email library decodes the encapsulation transparently for you, which gets rid of any QP-escaped line breaks, like the one in your question. For the record, quoted-printable can break up a long line anywere, including in the middle of the value you are attempting to extract, so you really do want to decode before attempting to extract anything.

Answer 3

If it's acceptable for you to first remove all the line breaks =^M\n from the text, then it's quite simple:

import re

email_body = open("1.txt").read().replace("=^M\n", "")

matches = re.findall(r"(?<=MACHINE:)\s*(\w+)", email_body)

print(matches)
print(list(set(matches)))

Output:

['p1prog07', 'p2prog06', 'p2prog06', 'p1prog07', 'ldnv260']
['p2prog06', 'ldnv260', 'p1prog07']

The positive look-behind is a non-capturing group, so the only captured group in the regex is your desired string.
