Python3解析邮件正文的方式与Python2不同

目前,我正在开发一个电子邮件解析器,它只需使用imaplib建立与我的gmail帐户的连接并阅读新的电子邮件。

这一切都很好,使用python2(即“python my script.py”)运行我的脚本时,结果与预期一样

例如,如果我有一封这样的电子邮件:

To: receiver@qwerty.com
From: sender@asdf.com
Subject: Test Subject

Test1
Test2

我的脚本将按预期输出:

To: receiver@qwerty.com
From: sender@asdf.com
Subject: Test Subject
Body: Test1
Test2

但是,当使用python3(即“python3 myScript.py”)运行此命令时,结果不同,转义字符显示在消息正文中,请参见以下内容:

To: receiver@qwerty.com
From: sender@asdf.com
Subject: Test Subject
Body: b'Test1\r\nTest2\r\n'

下面是用于此过程的代码:

def readMailbox(mail):
    res, data = mail.uid('search', None, 'UNSEEN')
    i = len(data[0].split())

    for x in range(i):
        latestEmailUID = data[0].split()[x]
        result, emailData = mail.uid('fetch', latestEmailUID, '(RFC822)')
        emailMessage = email.message_from_string(emailData[0][1].decode('utf-8'))

        emailFrom = str(email.header.make_header(email.header.decode_header(emailMessage['From'])))
        emailTo = str(email.header.make_header(email.header.decode_header(emailMessage['To'])))
        subject = str(email.header.make_header(email.header.decode_header(emailMessage['Subject'])))

        # Body details
        for part in emailMessage.walk():
            if part.get_content_type() == 'text/plain':
                body = part.get_payload(decode=True)
                print('To: %s' % emailTo)
                print('From: %s' % emailFrom)
                print('Subject: %s' % subject)
                print('Body: %s' % body)

我需要能够捕获字符串体,而不显示转义字符供以后使用。有谁能向我解释一下为什么会发生这种情况,或者我在python3中需要做些什么才能正常解析邮件的正文?

感谢您的时间,任何正确的指导方向将不胜感激!
