如何确定电子邮件是否经过Base64编码? [英] How do I determine if an email is Base64 encoded?

问题描述

我很难确定文本电子邮件的正文是否为base64编码. 如果是，则使用以下代码行； 利用jython 2.2.1

I am having difficulty determining if the body of a text email message is base64 encoded. if it is then use this line of code; making use of jython 2.2.1

dirty=base64.decodestring(dirty)

其他都照常进行.

这是我有atm的代码.哪行代码可以让我从电子邮件中提取出来:

This is the code I have atm. What line of code will allow me to extract this from the email:

"Content-Transfer-Encoding:base64"

"Content-Transfer-Encoding: base64"

import email, email.Message
import base64

def _get_email_body(self):
    try:
        parts=self._email.get_payload()
        check=parts[0].get_content_type()
        if check=="text/plain":
            part=parts[0].get_payload()
            enc = part[0]['Content-Transfer-Encoding']
            if enc == "base64":
                dirty=base64.decodestring(dirty)
        elif check=="multipart/alternative":
            part=parts[0].get_payload()
            enc = part[0]['Content-Transfer-Encoding']
            if part[0].get_content_type()=="text/plain":
                dirty=part[0].get_payload()
                if enc == "base64":
                    dirty=base64.decodestring(dirty)
            else:
                return "cannot obtain the body of the email"
        else:
            return "cannot obtain the body of the email"
        return dirty
    except:
        raise

好的，此代码现在可以使用！谢谢大家

OKAY this code works now! thanks all

推荐答案

尝试:

enc = msg['Content-Transfer-Encoding']

这是一个标头，因此您将无法看到它.您应该能够到达找到主题的地方.

It's a header so you won't be able to get it looking at the body. You should be able to get at the same place you find out the Subject.
