好吧！没人回答，自己弄了一下午，最后用nginx做反向代理弄好了！

@qinyang912 写下解决方法啊！

@youqingkui socket.io还是照常开发，配置一个nginx的https的反向代理就行。下面是nginx反向代理的配置代码

server{
        listen 443 ssl;
        server_name xxx.xxx.com;
        ssl_certificate /root/certs/test.crt;
        ssl_certificate_key /root/certs/test.key;
        ssl_session_cache shared:SSL:1m;
        ssl_session_timeout 5m;
        ssl_ciphers HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers on;
        location /{
                proxy_pass http://localhost:3000;
                proxy_set_header Host $host;
				proxy_http_version 1.1;
				proxy_set_header Upgrade $http_upgrade;
				proxy_set_header Connection "upgrade";
				proxy_read_timeout 86400;
        }
}
