Question

我正在尝试阅读上一封收到的电子邮件中的信息：

    mail = imaplib.IMAP4_SSL('imap.gmail.com')
    mail.login('test1@gmail.com', 'ABC#')
    mail.list()
    mail.select("inbox")

    result, data = mail.search(None, "ALL")
    ids = data[0]  # data is a list.
    id_list = ids.split()  # ids is a space separated string
    latest_email_id = id_list[-1]  # get the latest

    #print ("latest_email_id= ", latest_email_id)
    result, data = mail.fetch(latest_email_id, "(RFC822)")
    raw_email = data[0][1]

“ raw_email”的打印语句是这样的（请注意，出于安全原因，我更改了信息：

我已经阅读了有关阅读电子邮件信息的一些stackoverflow。即python imaplib to get gmail inbox subjects titles and sender name

他们大多认为返回的数据是元组，并且对此有些怀疑

   for response_part in data:
      if isinstance(response_part, tuple):
          msg = email.message_from_string(response_part[1])
          varSubject = msg['subject']
          varFrom = msg['from']

如何检索主题和收件人等信息。
自从我尝试过

以来，它似乎不是字典。

dTemp = {}
dTemp = raw_email
dTemp["Subject"]

最后一条语句给我一个错误

Answer 1

要解析电子邮件，最好使用内置的email.parser模块。

如果您将raw_email设为bytes，则可以使用email.parser.BytesParser()对其进行解析：

>>> parser = email.parser.BytesParser()
>>> parsed_message = parser.parsebytes(email_body, headersonly=True)  # or False...

然后请参阅email.message.Message上的文档，以从消息中访问数据，但通常它是这样工作的：

>>> parsed_message["Subject"]
'Welcome to the X Portal'
>>> parsed_message["From"]
'Y Ferdowsian <pingY@gmail.com>'
>>> parsed_message["To"]
'zXtest@gmail.com'
