我怎样才能得到更多的细节会发生什么？我怎样才能正确处理这个异常？

我对这段代码没有 unicode 问题（没有InboundMailHandler）：

message = mail.InboundEmailMessage(request.body)
msg_body = message.subject

编辑：

我在主题字段中进行了一些测试，主题是 unicode，但如果您dev_appserver > Inbound Mail不是unicode，请首先找到编解码器并解码主题。"àèé"msg_bodytype(msg_body)

message = mail.InboundEmailMessage(request.body)
msg_body = message.subject # if unicode or
msg_body = message.subject.decode("ascii") # if ascii then
_str = msg_body.encode("utf-8") # str

import base64

message_raw = request.body.encode('UTF-8')
message_decoded = base64.urlsafe_b64decode(message_raw)
message = InboundEmailMessage(message_decoded)
