JSP 웹 브라우저 검증 연습

  1   getHeader()를 이용한 브라우저 검증

---

 웹 프로젝트를 진행할 때 각가의 브라우저마다 지원하는 내용이 다르기 때문에 꼭! 브라우저를 확인해야한다. 요청 브라우저의 정보는 Header에 각각 저장이되며, 이러한 정보는 HttpServletRequest 객체제 저장되어 전송되게 된다.

HttpServletRequest 객체가 제공하는 getHeader()메소드를 이용하여 요청단의 OS, 및 브라우저를 확인하는 간단한 예제이다.

  2   Header에 담기는 정보들

---

1. host
2. connection
3. accept
4. user-agent(OS 및 브라우저의 정보)
5. referer(요청 URL)
6. accept-encoding
7. accept-language
8. cookie

  3   Jsp source

---

  4   Java source

---

한가지 중요한정보는 브라우저 검증 순서이다. 내 노트북만 그런줄 알았는데, 회사의 코드도 이렇게 진행이 되어있었다. 순서는 밑과 같은 순서이다.(PC에 많은 종류의 브라우저가 설치되어있으면 이렇게 출력이되는건가 -_-??)

Opera - Chrome - Safari - Firefox - IE 시리즈

 이유는 Header의 엘리먼트중 user-agent에 브라우저 정보가 담겨있는데, Opera및 Chrome등이 다음과같은 정보를 전송한다.

Opera 디버그

http-bio-8080-exec-6> [2013-10-16 11:02:54] [HeaderTest] [40] [DEBUG] 엘리먼트->user-agent 내용->Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.69 Safari/537.36 OPR/17.0.1241.45

Chrome 디버그

http-bio-8080-exec-4> [2013-10-16 11:03:36] [HeaderTest] [40] [DEBUG] 엘리먼트->user-agent 내용->Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.69 Safari/537.36

Safari 디버그

http-bio-8080-exec-10> [2013-10-16 11:03:10] [HeaderTest] [40] [DEBUG] 엘리먼트->user-agent 내용->Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/534.57.2 (KHTML, like Gecko) Version/5.1.7 Safari/534.57.2

 

 디버그 정보를 보면 Opera 브라우저의 경우 Opera 뿐만 아니라 Safari, Chrome의 정보가 포함되어있고, Chrome의 경우 Safari의 정보가 같이 출력이 되게된다. 

그렇기 때문에 순서를 제멋대로 정하면 Opera브라우저를 사용해도 Chrome을 사용하고있다는 엉뚱한 결과가 튀어나올수도 있기 때문에 조심해야한다.
