解析 multipart/related 封电子邮件

Question

我正在尝试解析电子邮件并将其中的表格转换为 pandas 数据帧。由于一些电子邮件是多部分的，因此我从 .

中提取了一些代码

以下代码工作正常，但它因 multipart/related 封电子邮件而中断（未找到表格）。

HOST = 'imap.gmail.com'
m = imaplib.IMAP4_SSL(HOST, 993)
m.login(USERNAME, PASSWORD)
m.select('Inbox')

result, data = m.uid('search', None, "UNSEEN", '(FROM "xxx@xxx.xxx")')
print(result)
if result == 'OK':
      for num in data[0].split()[:]:
            result, data = m.uid('fetch', num, '(RFC822)')
            if result == 'OK':
                  email_message = email.message_from_bytes(data[0][1])
                  b = email_message 
                  body = ""

                  print(b.is_multipart())
                  if b.is_multipart():
                      for part in b.walk():
                          ctype = part.get_content_type()
                          cdispo = str(part.get('Content-Disposition'))

                          # skip any text/plain (txt) attachments
                          if ctype == 'text/plain' and 'attachment' not in cdispo:
                              body = part.get_payload(decode=True)  # decode
                              break
                  else:
                      body = b.get_payload(decode=True)
                  soup = BeautifulSoup(body)
                  table = soup.find_all('table')
                  df = pd.read_html(str(table))[0]
                  display(df)

这是 multipart/related 一封电子邮件的 header：

有什么想法吗？谢谢
