达芙妮拒绝所有远程请求

Question

我有一个项目，在该项目中我使用通道并且在本地一切正常，但是当我部署在 Heroku 上时，每次我尝试连接时都会收到 403。起初我以为问题出在 Heroku 上，因为我在本地对其进行了测试，甚至在本地使用了 Heroku 中的数据库和 redis 实例，一切正常。

但是，当我使用 ngrok 打开到我的本地主机的 public 隧道时，我发现结果与 Heroku 中的结果相同。对于每个请求，我都会收到 403 并尝试调试它并没有多大帮助，因为事件循环有时会突然控制或者我会收到超时错误。除了一个在本地访问而另一个在远程访问之外，设置完全相同。这就是我开始达芙妮的方式： daphne weout.asgi:application --port 8000 --bind 0.0.0.0 -v 3.

我的库版本：

Django==2.0.7
频道==2.2.0
channels-redis==2.4.0
达芙妮==2.3.0

将 Daphne 的 versbosity 设置为最大，这是我尝试连接时得到的结果：

我使用 Daphne 为我的普通 Django 视图和 websocket 消费者提供服务。 Django 视图一切正常，所以只有在连接到消费者时才会出现问题

有没有人在远程访问Dapnhe时遇到类似的问题？起初我尝试用 uvicorn 搭配 gunicorn 但他们有 bug when the consumer is closed during the initial connection phase 所以我换回达芙妮

Answer 1

原来是AllowedHostsOriginValidator！那肯定浪费了我很多时间。顺便说一下，如果没有 Origin header，你知道中间件如何处理来自移动应用程序或其他来源的请求吗？

无论如何我暂时删除它并且当前问题已解决
