判断微信浏览器

如何判断微信浏览器?

前端:

//是否是微信浏览器
	    isWeiXinBrowser: function (){ 
	    	var ua = window.navigator.userAgent; 
	    	if(ua.match(/MicroMessenger/i) ){ 
	    		return true; 
	    	}else{ 
	    		return false; 
	    	} 
	   } 

后台:

    public static boolean isMicromessengerBrowser(HttpServletRequest request) {
        String userAgent = request.getHeader("user-agent").toLowerCase();
        return userAgent.contains("micromessenger");
    }
