我需要从Django的后端到前端的推送消息，最后我找到了这个Twisted + Django服务器但在产品环境中我们使用nginx代理请求到Django，我很困惑可以hendrix和nginx工作一起？
如果是，那么如何编写nginx.conf？
答案 0 :(得分：0)
是的，您可以使用nginx代理传递给hendrix，方法与使用任何其他WSGI / ASGI容器相同。
This Question有样本配置来执行此操作。

今天我尝试将原来的nginx配置更改为反向代理hendrix，这里有一些片段：
upstream django {
server localhost:8000;
}
server {
listen 80;
server_name localhost;
location /static/ {
#root /var/www;
alias /var/www/static;
}
location / {
proxy_pass http://django;
proxy_pass_header Server;
proxy_set_header Host $host;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
然后我重新启动nginx并启动hendrix：hx start --log ./test.log
终于工作了，但我发现了一些警告信息： *
WebSocket连接到'...'失败：WebSocket期间出错 握手：'Connection'标头值不是'Upgrade'：keep-alive socket.io.js：2371
*
在一些google消息之后，我发现nginx版本必须要高1.3.13，所以我将nginx更新为1.10.1（稳定），警告消息消失。但是如果想在我的生产环境中使用hendrix，需要多个hendrix-worker，所以我尝试：hx start -w 2，输出失败：
root@proxy:/vagrant/hendrix_taste/hendrix/examples/django_hx_chatserver/example_app# hx start -w 2
