웹 브라우저 종류 버전 체크

웹 브라우저 종류 버전 체크

보통 프론트 엔드에서 사용하는 로직으로 javascript에서 웹 브라우저 종류, 버전, OS의 버전등을 체크하여 알맞는 ActiveX 같은 파일을 다운받을 수 있게 하거나, 웹브라우저에 맞는 스크립트 개발을 이용할 때 사용한다.

여기에선 java Servlet에서 체크하는 로직으로 사용한다.

<iframe> 기반으로 url이나 api로 호출할때 사용자의 웹 브라우저를 종류, 버전을 수집하거나 확인하는 목적으로 사용한다.

먼저 테스트 케이스를 작성하였다.

          @Test

          public void browserSearchTest() {

                   List<String> list = new ArrayList<>();

                   String userAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36";

//                 0. Internet Explorer 9

                   String userAgent0 ="Mozilla/5.0 (compatible; MSIE 9.0; Windows Phone OS 7.5; Trident/5.0; IEMobile/9.0";

                   list.add(userAgent0);

//                 1. Internet Explorer 11

                   String userAgent1 ="Mozilla/5.0 (Windows NT 6.3; WOW64; Trident/7.0; rv:11.0) like Gecko";

                   list.add(userAgent1);

//                 1-1. Internet Explorer 10

                   String userAgent2 = "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0)";

                   list.add(userAgent2);

//                 2. Safari

                   String userAgent3 = "Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/534.57.2 (KHTML, like Gecko) Version/5.1.7 Safari/534.57.2";

                   list.add(userAgent3);

//                 3. Chrome

                   String userAgent4 = "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.101 Safari/537.36";

                   list.add(userAgent4);

//                 4. Opera

                   String userAgent5 = "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.101 Safari/537.36 OPR/17.0.1241.53";

                   list.add(userAgent5);

//                 4-1. Opera 구버전

                   String userAgent6 = "Opera/9.80 (Windows NT 6.1; WOW64; U; ko) Presto/2.10.229 Version/11.62";

                   list.add(userAgent6);

//                 5. Firefox

                   String userAgent7 = "Mozilla/5.0 (Windows NT 6.3; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0";

                   list.add(userAgent7);

                   

                   for(String val : list) {

                             System.out.println(browserVersionTest(val));

                   }

                   

          }

          //웹브라우저 버전체크

          private String browserVersionTest(String agentValue) {

                             String userAgent = agentValue;

                             String browserVersion  = "";

                             if(userAgent.indexOf("Opera") > -1 ||  userAgent.indexOf("OPR") > -1) {

                                      browserVersion = "Opera";

                             }else if (userAgent.indexOf("Firefox") > -1) {

                                      browserVersion = "Firefox";

                             }else if (userAgent.indexOf("Safari") > -1) {

                                      if( userAgent.indexOf("Chrome") > -1){

                                                browserVersion = "Chrome";  

                                      }else {

                                                browserVersion = "Safari";

                                      }

                             }else if ( userAgent.indexOf("Chrome") > -1) {

                                      browserVersion = "Chrome";

                             }else if(((userAgent.indexOf("MSIE") > -1) || (userAgent.indexOf("Trident") > -1))) {

                                      String word = "";

                                      if((userAgent.indexOf("MSIE") > -1)) {

                                                word = "MSIE ";

                                      }else if((userAgent.indexOf("Trident") > -1)) {

                                                word = "Trident/.*rv:";

                                      }

                                                Pattern browserPattern = Pattern.compile(word+"([0-9]{1,}[0-9]{0,1})");

                                                Matcher version = browserPattern.matcher(userAgent);

                                                if(version.find()) {

                                                          browserVersion = "MSIE" + version.group(1);

                                      }

                             }

                             return browserVersion;

          }

결과)

참고) 실세 사용시 함수호출시 HttpServletReqeust로 넘겨서 getHeader("User-Agent") 값을 받아서 사용하면된다.

public void browserInfo(HttpServletRequest request) {

    String userAgent = request.getHeader("User-Agent");

}
