nginx 可以转发websocket

nginx 配置,注意代理端口后面不要有“/”
location /mysocket/ {
	      proxy_pass http://xxx.com:3000; 
	      proxy_http_version 1.1;
	      proxy_set_header Upgrade $http_upgrade;
	      proxy_set_header Connection 'upgrade';
	      proxy_set_header Host $host;
	      proxy_cache_bypass $http_upgrade;
    }

socket.io client
'/'代表http:xxx.com/,使用path选择，替换默认的socket.io选项，不需要使用ws：xxx.com:3000这类地址，直接使用http,或者https，socket.io会自动将其转换成websocket的
let socket= io('/',{
  path: '/mysocket',
  query: {
    args: "122"
  }
});

socket.io server
 const io = require('socket.io')(server,{
        path: '/mysocket'
    });
