我有一个项目，在其中使用渠道，并且在本地一切正常，但是当我在Heroku上部署时，每次尝试连接时我得到403。最初，我以为问题是Heroku，因为我在本地进行了测试，甚至在本地使用了Heroku的数据库和Redis实例，并且一切正常。
但是，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，我得到403并尝试对其进行调试没有太大帮助，因为事件循环有时会突然获得控制权，或者会出现超时错误。设置完全相同，只是其中一个正在本地访问，而另一个正在远程访问。
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lib版本：
- Django == 2.0.7
- channels == 2.2.0
- channels-redis == 2.4.0
- daphne == 2.3.0
在Daphne的通用性设置为最大的情况下，这是我尝试连接时得到的：

我使用Daphne为我的常规Django视图和websocket使用者提供服务。一切都适用于Django视图，因此仅当连接到使用者时才会出现问题
有人远程访问Dapnhe时是否有类似的问题？ 刚开始，我尝试将uvicorn和gunicorn搭配使用，但是它们有bug when the consumer is closed during the initial connection phase，所以我改回了Daphne
