需要cookie验证的java抓包程序使用java编写的抓包程序，对于一般的抓包比较简单，这里主要是对需要cookie验证的网页进行抓包，代码比较简单，自行下载理解。立即下载

import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Cookie工具类

public class CookieUtils {

    /**

    public static void addCookie(HttpServletResponse response, String name, String value, int maxAge) {
        Cookie cookie = new Cookie(name, value);
        cookie.setPath("/");
        if (maxAge > 0) {
            cookie.setMaxAge(maxAge);
        }
        response.addCookie(cookie);
    }

    /**

    }
