邮件内容解析
背景：
将手机验证码转发到qq邮箱后，通过python代码解析邮件获取验证码。
以下代码主要展示如何解析邮件正文内容。
具体代码功能，可以通过查看imaplib的用法进行了解。
import imaplib
import email
from email.parser import Parser
from email.header import decode_header
from flanker import mime
import re
import time
# 连接到邮件服务器
imap_server = imaplib.IMAP4_SSL("imap.qq.com")
# 登录
imap_server.login("13***********[email protected]", "kp**********iig")
# 选择邮件箱
imap_server.select("INBOX") # 选择收件箱
typ, data = imap_server.search(None,'Subject','手机短信转发'.encode('utf-8')) # 通过主题搜索邮件
for msg_id in data[0].split():
res, msg = imap_server.fetch(msg_id, '(RFC822)')
for response in msg:
if isinstance(response,tuple):
msg=email.message_from_bytes(response[1])
subject,encoding=decode_header(msg['Subject'])[0]
if isinstance(subject,bytes):
subject=subject.decode(encoding)
From,encoding=decode_header(msg.get('From'))[0]
if isinstance(From, bytes):
From=From.decode(encoding)
date_time = msg.get("Date") # 解析时间
dt = time.strptime(date_time[5:24],"%d %b %Y %H:%M:%S")
print('\n')
print('Sub:',subject)
print('From:',From)
print("date_time...", type(date_time),date_time, dt)
body = ""
if msg.is_multipart():
print('**** ---multipart--')
for part in msg.walk():
content_type=part.get_content_type()
content_disposition=str(part.get('Content-Disposition'))
#body
try:
body=part.get_payload(decode=True).decode()
except:
pass
if content_type=='text/plain' and 'attachment' not in content_disposition:
print(body)
#attachment
elif 'attachment' in content_disposition:
filename=part.get_filename()
#if filename:
# folder_name=clean(subject)
# if not os.path.isdir(folder_name):
# os.mkdir(folder_name)
# filepath=os.path.join(folder_name,filename)
# open(filepath,'wb').write(part.get_payload(decode=True))
# print(filepath,'save')
else:
print('****---singlepart---')
content_type=msg.get_content_type()
body=msg.get_payload(decode=True).decode()
#if content_type=='text/plain':
# print(body)
print("- --- -----", body)
imap_server.close()
imap_server.logout()
