我正在使用Django通道教程,我做了教程中的任何事情,当我点击我的消息的发送按钮时,我的终端出现错误:“GET /ws/chat/lobby/ HTTP/1.1”404 2232

我该如何解决这个问题?
我试了python manage.py runserver
,得到了:
Not Found: /ws/chat/lobby/
[11/Nov/2022 11:15:36] "GET /ws/chat/lobby/ HTTP/1.1" 404 2232

我有类似的问题,在我的情况下,这是一个事实,即请求没有处理的一个aplogic工作。我有它固定与:
pip install channels[daphne]
然后将
daphne
添加为INSTALLED_APPS
中的第一个条目。您可以从列表的末尾删除channels
。我的工作现在是这样配置的:字符串
Daphne控制
runserver
命令。如果您在INSTALLED_APPS
末尾添加channels
并单独启动一个worker,则可以不使用它。有关更多信息,请参阅通道教程here。
