达芙妮拒绝所有远程请求

Question

我有一个使用通道的项目，并且本地一切运行良好，但是当我部署在 Heroku 上时，每次尝试连接时都会收到 403 错误。起初我以为问题出在 Heroku 上，因为我在本地测试了它，甚至在本地使用了 Heroku 的数据库和 redis 实例，一切正常。

但后来，当我使用ngrok打开到本地主机的公共隧道时，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。设置完全相同，只是一个是本地访问，另一个是远程访问。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：

• 姜戈==2.0.7
• 频道==2.2.0
• 通道-redis==2.4.0
• 达芙妮==2.3.0

将 Daphne 的详细程度设置为最大后，这就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，因此仅在连接到消费者时才会出现问题

有人在远程访问 Dapnhe 时遇到类似的问题吗？起初，我尝试了 uvicorn 与 Gunicorn 一起使用，但是当消费者在初始连接阶段关闭时，它们有一个错误，所以我切换回 Daphne

原来是AllowedHostsOriginValidator！这肯定浪费了我很多时间。顺便说一句，您知道中间件对于来自移动应用程序或其他没有Origin标头的来源的请求将如何表现吗？

无论如何，我暂时删除了它，当前的问题已解决
