Python 用于验证传入Twilio请求的装饰程序

我试图遵循这个非常直接的指南，了解如何防止非twilio请求命中我为传入twilio消息设置的webhook url。它主要涉及复制他们作为装饰器开发的函数，并将其应用于处理传入消息的视图

不幸的是，在我将decorator应用于处理传入消息的视图之后，我立即遇到了这个错误

Traceback (most recent call last):

    response = get_response(request)

谢谢你的帮助

RequestValidator

不接受无。这应该可以解决这个问题：

validator = RequestValidator(os.environ.get('TWILIO_AUTH_TOKEN', ''))
