当正文中有unicode字符时,使用python解析Gmail电子邮件

Question

我写了一个脚本来解析一封电子邮件.从Mac OS X Mail客户端接收信件时它工作正常(到目前为止只测试了这个),但是当字母在其正文部分中包含unicode字母时,我的解析器会失效.

例如,我发送了一条包含内容的消息???.

这是我的脚本部分同时解析正文和附件:

p = FeedParser()
p.feed(msg)
msg = p.close()
attachments = []
body = None
for part in msg.walk():
  if part.get_content_type().startswith('multipart/'):
    continue
  try:
    filename = part.get_filename()
  except:
    # unicode letters in filename, set default name then
    filename = 'Mail attachment'

  if part.get_content_type() == "text/plain" and not body:
    body = part.get_payload(decode=True)
  elif filename is not None:
    content_type = part.get_content_type()
    attachments.append(ContentFile(part.get_payload(decode=True), filename))

if body is None:
    body = ''

好吧,我提到它适用于来自OS X Mail的信件,但是使用Gmail信件却没有.

我的脚本给了我以下的身体????.如何解码才能???回来？

好吧,我自己找到了解决方案.我现在会做一些测试,如果有任何失败,现在就让你们.

我需要再次解码身体:

body = part.get_payload(decode=True).decode(part.get_content_charset())
