關於websocket遇到的問題

1.nginx進行代理：

http://nginx.org/en/docs/http/websocket.html

location /chat/ { proxy_pass http://backend; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade";}

或者

http { map $http_upgrade $connection_upgrade { default upgrade; '' close; } server { ... location /chat/ { proxy_pass http://backend; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; } }
