[JAVA] user agent 브라우저/버전 정보 확인

 

Java에서 브라우저와 버전을 확인하기 위한 예제입니다.

private static String UserBrowserChk(IckContext context) {

	String userAgent = context.getRequest().getHeader("user-agent");
	String browser = "";

	if(userAgent.indexOf("Trident") > -1 || userAgent.indexOf("MSIE") > -1) { //IE

		if(userAgent.indexOf("Trident/7") > -1) {
			browser = "IE 11";
		}else if(userAgent.indexOf("Trident/6") > -1) {
			browser = "IE 10";
		}else if(userAgent.indexOf("Trident/5") > -1) {
			browser = "IE 9";
		}else if(userAgent.indexOf("Trident/4") > -1) {
			browser = "IE 8";
		}else if(userAgent.indexOf("edge") > -1) {
			browser = "IE edge";
		}

	}else if(userAgent.indexOf("Whale") > -1){ //네이버 WHALE
		browser = "WHALE " + userAgent.split("Whale/")[1].toString().split(" ")[0].toString();
	}else if(userAgent.indexOf("Opera") > -1 || userAgent.indexOf("OPR") > -1){ //오페라
		if(userAgent.indexOf("Opera") > -1) {
			browser = "OPERA " + userAgent.split("Opera/")[1].toString().split(" ")[0].toString();
		}else if(userAgent.indexOf("OPR") > -1) {
			browser = "OPERA " + userAgent.split("OPR/")[1].toString().split(" ")[0].toString();
		}
	}else if(userAgent.indexOf("Firefox") > -1){ //파이어폭스
		browser = "FIREFOX " + userAgent.split("Firefox/")[1].toString().split(" ")[0].toString();
	}else if(userAgent.indexOf("Safari") > -1 && userAgent.indexOf("Chrome") == -1 ){ //사파리
		browser = "SAFARI " + userAgent.split("Safari/")[1].toString().split(" ")[0].toString();
	}else if(userAgent.indexOf("Chrome") > -1){ //크롬
		browser = "CHROME " + userAgent.split("Chrome/")[1].toString().split(" ")[0].toString();
	}

	LOG.debug("userAgent 확인 ["+userAgent+"]");
	LOG.debug("브라우저/버전 확인 ["+browser+"]");

	return browser;
}

 

 

context.getRequest().getHeader("user-agent");는 java 프레임워크에 따라 다르므로

request.getHeader("user-agent"); 로 사용 가능합니다.
