InboundEmailMessage引發的UnicodeDecodeError例外

在我的生產日誌我看到許多錯誤，如下面InboundEmailMessage引發的UnicodeDecodeError例外

我怎樣才能得到更多的細節會發生什麼？我怎樣才能妥善處理這個異常？

我沒有unicode的問題與此代碼（不InboundMailHandler）：

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

編輯：

我在dev_appserver > Inbound Mail做了一些測試，在主題欄"àèé"和對象是Unicode，但如果您的msg_body不是unicode，請首先找到type(msg_body)的編解碼器並首先解碼該主題。

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

感謝。我遇到的主要問題是這個問題只發生在一些電子郵件上，而不是所有電子郵件。甚至在我開始解析它之前。我甚至不知道如何獲得消息的細節，這導致了這個問題。 –

拋開'InboundMailHandler'可以幫助調試。只有找到「奇怪」的字符時，你的應用纔會提出unicode錯誤。如果您提交的是主題。順便說一句，編碼py27是一個黑洞。 –

我是否正確理解你建議使用'webapp2.RequestHandler' /'post'而不是'InboundMailHandler'？ –

import base64 

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