[nginx]配置nginx支持websocket解决返回400错误问题

当nginx里没有配置支持webocket时 , 但是已经配置了域名 比如:ws://gofly.sopans.com/ws_visitor 

直接js连会返回400的错误

需要在nginx  location 块下增加这三个header头 , 把http连接升级为websocket连接

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

比如我的开源客服gofly中

server{

listen 80;

server_name gofly.sopans.com;

access_log /var/log/nginx/gofly.sopans.com.access.log main;

client_max_body_size 10M;

location /static {

root /var/www/html/go-fly;

}

location / {

proxy_pass http://127.0.0.1:8081;

proxy_http_version 1.1;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header Upgrade $http_upgrade;

proxy_set_header Connection "upgrade";

}

}
