Java判断cookie中是否有某个具体的cookie

/**
 * 从request 中取出 cookie
 */
private String getUgcCookie(HttpServletRequest request) {
    String ugcInfo = null;
    try {
        Cookie[] cookies = request.getCookies();
        if (cookies == null) {
            return null;
        }
        for (Cookie cookie : cookies) {
            if (CookieConst.COOKIE_UGC.equals(cookie.getName())) {
                ugcInfo = cookie.getValue();
            }
        }
    } catch (Throwable e) {
        logger.error("getUgcCookie error, [msg = {}]", e.getMessage(), e);
    }
    return ugcInfo;
}
