需要幫助修復500錯誤蟒蛇/燒瓶應用程序

Question

我正試圖在燒瓶框架上運行一個簡單的Python應用程序Twilio API。我在virtualenv與以下相關發展：

• 瓶
• Jinja2的
• MarkupSafe
• WERKZEUG
• argparse
• gunicorn
• httplib2的
• itsdangerous
• twilio
• unittest2
• 的wsgiref

當我運行使用工頭我的索引頁面呈現精緻和負載TwiML很好，但我在那裏我處理短信回覆/短信頁面繼續接收500錯誤，「服務器遇到內部錯誤，無法完成您的請求。無論是服務器超載或有錯誤的應用程序，「如果我推到Heroku上出現同樣的錯誤下面是我的代碼，任何想法

Answer 1

我是針對由Joel Franusic，爲Twilio開發者倡導的解決方案。事實證明，這是一個unicode的問題。我使用的文本從其他網站形成測驗。在文本中是統一的一個隱藏的撇號起源而不是預期的UTF-8，這阻止了格林獨角獸從r unning。

教訓教訓 - 不要複製webtext，重新輸入所有的，以避免錯誤，或者在文本編輯器或IDE，你可以分辨出兩者的字體類型之間的差異用明顯的字體。
