Python Flask 服务器不能与 Twilio 一起工作

Question

我一直在尝试使用 Raspberry Pi 创建人员日志来记录谁在屋子里，回复 Twilio 短信和回复谁在家。我正在使用 flask 将服务器构建到 Twilio，但是当我向 'whoshome' 查询发送短信时，我根本没有收到任何回复。它应该回复谁在家，尽管目前只分配了一个人！此外，Twilio 应该向仪表板中的预定义客户端发送 POST 请求，然后在收到短信后询问说明。

这里是 Twilio 布道者。

看起来您正在return从您的路线进行空试：

return ' '

由于您已将路由标记为接受 GET 请求，因此您可以通过在浏览器中打开此路由的 public URL 并查看 return 是什么来检查发生了什么编辑。您还可以运行一个针对路由的 cURL 请求来验证它的 return 符合您的预期。

我认为您可能需要 return 来自路由的 TwiML 响应而不是空字符串：

return str(r)

希望对您有所帮助。
