nginx如何实现跳转到指定接口的功能

server {
        listen 80;
        server_name yunmasoft.com www.yunmasoft.com;
        if ( $uri ~* "^/user/loginInput$" ) {
                rewrite ^/(.*)$ http://123.57.250.51/$1 redirect;
        }
        location / {
                proxy_pass    http://182.92.97.72:8083;
                # proxy_redirect on ;

                index index.php index.html index.htm;
        }
        error_page 500 502 503 504 /50x.html;
