将电子邮件属性转换为JSON字典格式

Question

我写了一个代码来阅读电子邮件并打印其内容。我想创建一个有序的字典，并将.items（）中存在的电子邮件属性转换为dict，并且还想在字典中打印正文部分，而不是在msg.items（）中。我该如何实现？

import email
import imaplib2
from collections import OrderedDict

.... 
def read_mail_from_server():
    try:
        mail = imaplib2.IMAP4_SSL(EMAIL_SERVER, 993)
        mail.login(EMAIL_USER, EMAIL_PASSWORD)
        mail.select('INBOX')

        typ, raw_data = mail.search(None, 'ALL')
        mail_ids = raw_data[0]
        for i in mail_ids.split():
            result, msg_data = mail.fetch(i, '(RFC822)')

            for each_response in msg_data:
                if isinstance(each_response, tuple):
                    msg = email.message_from_string(each_response[1])
                    email_subject = msg['subject']
                    print('Subject:' + email_subject + '\n')
                    email_from = msg['from']
                    print('From:' + email_from + '\n')

                    items_list = msg.items()
                    print(items_list)
                    dict_items = OrderedDict(items_list)
                    print(dict_items)

                    body = ''
                    if msg.is_multipart():
                        for part in msg.walk():
                            ctype = part.get_content_type()
                            disp = str(part.get('Content-Disposition'))

                            if ctype == 'text/plain' and 'attachment' not in disp:
                                body = part.get_payload()
                                break
                            else:
                                body = msg.get_payload(decode=True)

                    print('body:' + body + '\n')
    except Exception, e:
        print str(e)


read_mail_from_server()

我得到的输出：

[('Return-Path', '<name@mail.com>'), ('Delivered-To', 
'recipient@mail.com'), ('Delivery-date', 'Tue, 14 May 2019 14:07:07 
+0530'), ('Subject', 'Fw: Tuesday'), ('Importance', 'Normal')]

Body:
URGENT: Sensitive Classifier Alert

我期望的输出：

 {
  'Body': 
       {
        URGENT: Sensitive Classifier Alert
       }
  'Delivered-To':'recipient@mail.com'
  'Delivery-date':'Tue, 14 May 2019 14:07:07+0530'
  'Return-Path':'<name@mail.com>'
  ....
 }
