Gunicorn 中 Django 通道的 WebSocket 连接问题

Question

我尝试使用 Django Channels 和 Daphne 实现实时聊天。它在我的本地服务器上运行良好，但现在我想使用 Gunicorn、nginx 在生产中实现它。但是，当我重新加载并重新启动并运行时，我在服务中收到错误（如下图所示）。我尝试修改我的服务，但仍然不起作用。由于没有具体的错误，我无法找出原因。我阅读了一些文档，我是否需要进行迁移？任何想法将不胜感激。

这是我尝试过的

服务Gunicorn

Nginx

    location / {
        include proxy_params;
        proxy_pass http://unix:/run/tev/tev.sock;

        #WebSocket support

        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        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_headers_hash_max_size 1024;
    proxy_headers_hash_bucket_size 128;

asgi.py配置

import os
from django.core.asgi import get_asgi_application
from channels.routing import ProtocolTypeRouter, URLRouter
#from django.core.asgi import get_asgi_application
from channels.auth import AuthMiddlewareStack
from main import routing
import main.routing

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'tev.settings')

django.setup()

django_asgi_app = get_asgi_application()

#application = get_asgi_application()
application = ProtocolTypeRouter({
    #"http": get_asgi_application(),
    "http": django_asgi_app,
    "websocket": URLRouter(
        main.routing.websocket_urlpatterns
    )
})

Answer 1

您只需将这些行移到 asgi.py 文件的顶部即可。

import os

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "your_project.settings")

import django

django.setup()

并且不要忘记将

nginx

服务中的套接字路由到 /ws url:

location /ws/ {
        proxy_pass http://unix:/run/daphne/daphne.sock;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        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-Proto $scheme;
    }
