request获取各种信息

private Map<String, String> getHeadersInfo(HttpServletRequest request) {    Map<String, String> map = new HashMap<String, String>();    Enumeration headerNames = request.getHeaderNames();    while (headerNames.hasMoreElements()) {        String key = (String) headerNames.nextElement();        String value = request.getHeader(key);        map.put(key, value);        //System.out.println(key+":"+value);    }    return map;}

private String getCookieId(HttpServletRequest request){    Cookie[] cookie = request.getCookies();    for (int i = 0; i < cookie.length; i++) {        Cookie cook = cookie[i];        System.out.println(cook.toString());        if(cook.getName().equalsIgnoreCase("eredg4.login.account")){ //获取键            System.out.println("account:"+cook.getValue().toString());    //获取值        }    }    return "";}
