频道 django nginx 502

Question

我在安装并将“频道”添加到设置中，然后添加到 asgi 文件后遇到了问题。 服务器崩溃，我得到 502 和 nginx 无法启动。 我怎样才能添加这些频道并开始工作

ASGI_APPLICATION = "mysite.asgi.application"

application = ProtocolTypeRouter({
"http": get_asgi_application(),
# Just HTTP for now. (We can add other protocols later.)
# WebSocket chat handler
"websocket": AuthMiddlewareStack(
    URLRouter([
        
    ])
),

})

求助，相信很多人都遇到过，谢谢

您是否正确配置了 Nginx？ 以下是示例 Nginx 配置。

upstream channels-backend {
    server localhost:8000;
}
...
server {
    ...
    location / {
        try_files $uri @proxy_to_app;
    }
    ...
    location @proxy_to_app {
        proxy_pass http://channels-backend;

        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Host $server_name;
    }
    ...
}
