Ready for Python code on port 39093...
127.0.0.1 - - [29/Nov/2016 14:51:17] "GET / HTTP/1.1" 200 216
127.0.0.1 - - [29/Nov/2016 14:51:17] "GET /favicon.ico HTTP/1.1" 400 23

이렇게 해서 39093 포트 를 열 고 브 라 우 저 에 직접 접근 할 수 있 습 니 다.

http://127.0.0.1:39093/

하지만 이렇게 코드 를 제출 할 때 bad request 를 알려 줍 니 다.
그래서 hosts 파일 을 설정 해 야 합 니 다.

127.0.0.1      local.liaoxuefeng.com

다음 방식 으로 접근:

http://local.liaoxuefeng.com:39093/
