Daphne拒绝所有远程请求

Question

我有一个项目，我使用渠道和本地一切都很好，但当我部署在Heroku，我得到403，每次我试图连接。起初，我认为问题出在Heroku，因为我在本地测试它，甚至在本地使用Heroku的数据库和redis实例，一切都正常。

但是，当我使用ngrok打开一个通往本地主机的公共隧道时，我发现结果和Heroku一样。对于每个请求，我得到403，并且尝试调试它没有多大帮助，因为事件循环有时只是突然控制，或者我得到超时错误。设置完全相同，其中一个是本地访问的，另一个是远程访问的。这就是我如何启动达芙妮：daphne weout.asgi:application --port 8000 --bind 0.0.0.0 -v 3。

我的库版本：

• Django==2.0.7
• channels==2.2.0
• 频道-redis=2.4.0
• daphne==2.3.0

随着Daphne的诗句被设置为最大，当我尝试连接时，这就是我得到的：

我使用Daphne为我的普通Django视图和websocket使用者提供服务。对于Django视图，一切都运行良好，所以只有连接到使用者时才会出现问题。

是否有人在远程访问Dapnhe时有类似的问题？一开始，我试过和古尼一起服务，但是他们有一个当使用者在初始连接阶段关闭时出错。，所以我换回了达芙妮。

Answer 1

原来是AllowedHostsOriginValidator！那肯定浪费了我很多时间。顺便问一下，没有Origin头的情况下，对于来自移动应用程序或其他来源的请求，该中间件将如何运行？

不管怎样，我暂时删除了它，现在的问题已经解决了。
