前两天折腾了下socketio，部署完发现通过nginx代理之后前端的socket无法和后端通信了，于是暴查一通，最后解决问题：
location / { proxy_pass http://127.0.0.1:9999; proxy_connect_timeout 60; 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-NginX-Proxy true; # 下面是关键 proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; # 这是配置webpysessoin丢失的问题 fastcgi_param SCRIPT_NAME ""; }
