我试图在带有Twilio API的烧瓶框架上运行一个简单的python应用程序。我正在virtualenv开发具有以下依赖项：
当我使用foreman运行时，我的索引页面呈现正常并加载TwiML很好，但我正在处理sms响应的/ sms页面继续收到500错误，“服务器遇到内部错误，无法完成您的请求。服务器过载或应用程序出错。“如果我推送到Heroku，会发生同样的错误。以下是我的代码，任何想法？

我被Twilio的开发者倡导者JoëlFranusic引导解决方案。事实证明这是一个unicode问题。我使用其他网站的文字来形成测验。在文本中是一个隐藏的unicode起源撇号而不是预期的UTF-8，这阻止了Green Unicorn的运行。
获得的经验教训 - 不要复制webtext，重新输入所有内容，以防止错误，或者在文本编辑器或IDE上使用明显的字体来判断两种字体类型之间的区别。
