同時(shí)代理http

2個(gè)服務(wù)：localhost:3000，localhost:8000，ws服務(wù)在localhost:3000上。
用nginx實(shí)現(xiàn)代理：

location /test/ {
            proxy_pass   http://localhost:8000/;
        }
        location / {
            proxy_hide_header X-Frame-Options;
            proxy_pass  http://localhost:3000;

            ＃代理ws
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_set_header Origin ""; #此句一定要加，不然cors不會(huì)通過
        }
