java HttpClient+Jsoup打造灌水利器再也不怕起火了

不知道多久以前就有过写个自动回帖的小软件一直没有实现,最近闲下来了遂研究了下,本人小菜对于HTTP协议一知半解只能在请教google大神了,把我的想法跟google大神说了之后,google大神说这小子不错,这是为防火事业做贡献啊!特赐予小弟以下神器:

1、HttpClient 4.3.1 (GA)

以下列出的是 HttpClient 提供的主要的功能,要知道更多详细的功能可以参见 HttpClient 的主页。

  • 实现了所有 HTTP 的方法(GET,POST,PUT,HEAD 等)
  • 支持自动转向
  • 支持 HTTPS 协议
  • 支持代理服务器等

2、Jsoup

jsoup 的主要功能如下

  • 从一个 URL,文件或字符串中解析 HTML
  • 使用 DOM 或 CSS 选择器来查找、取出数据
  • 可操作 HTML 元素、属性、文本
  • 使用与jquery几乎一样的语法

废话不多说直接进入正题,在HTTPClient源码包内包含example文件夹此文件夹内包含一些基本用法这些例子入门足够了找到ClientFormLogin.java具体解释注释已经很清楚了大致意思就是模拟HTTP请求存储cookies。

测试网站:http://bbs.dakele.com/

因为此网站对登录做了特殊处理所以与标准的DZ论坛可能会有些出入请自行修改

对网站的分析使用的chrome自带的审查元素,这个折腾了不少时间

登录地址:http://passport.dakele.com/login.do?product=bbs

输入错误的用户名和密码会发现实际登录地址为http://passport.dakele.com/logon.do注意【i/n的区别刚开始没注意以为见鬼了】

返回错误信息

{"err_msg":"帐号或密码错误"}

输入正确信息返回

直接输入rediret连接和正常登录

获取跳转链接:

                if(results.length==1){
                    loginResult = results[0];
                }
            }
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }finally{
            try {
                response2.close();

登录代码:

        boolean flag = false;
        LoginResult loginResult = getRedirectUrl();
        if(loginResult.getResult().equals("true")){
            cookieStore = new BasicCookieStore();

            } else {
                for (int i = 0; i < cookies2.size(); i++) {
                    
                }
            }
        }
        
        return flag;
    }
复制代码

到此已经登录成功可以进行只有登录号才能做的事了,什么?你不知道当然是灭火了

首先取得需要回复的帖子地址,列表页比较有规律所有没有写自动发现的所以写了个循环@1

复制代码
for(int i=1;i<200;i++){
            String basurl="http://bbs.dakele.com/forum-43-"+i+".html";
            log.info(basurl);
            List<String> urls = dakele.getThreadURLs(basurl);
            for(String url:urls){
                //log.info(url);
                ReplayContent content = dakele.preReplay(url);
                if(content!=null){
                    log.info(content.getUrl());
                    log.info(content.getMessage());
                    //dakele.replay( content);
                    //Thread.sleep(15300);
                }
            }
        }
复制代码

在列表页内获取帖子地址:

复制代码
String html = EntityUtils.toString(entity);
            Document document = Jsoup.parse(html,HOST);
            Elements elements=document.select("tbody[id^=normalthread_] > tr > td.new > a.xst");
            for(int i=0;i<elements.size();i++){
                Element e = elements.get(i);
                urList.add(e.attr("abs:href"));
            }
复制代码

在需要回复的帖子内获得需要提交的form表单地址以及构造回复内容

复制代码
public ReplayContent preReplay(String url){
        ReplayContent content = null;
        HttpGet get  = new HttpGet(url);
        get.setHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");
        get.setHeader("Accept-Language", "zh-CN,zh;q=0.8");
        get.setHeader("Connection", "keep-alive");
        get.setHeader("Host", HOST);
        get.setHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.101 Safari/537.36");
        try {
            CloseableHttpResponse response = globalClient.execute(get);
            HttpEntity entity = response.getEntity();
            String html = EntityUtils.toString(entity);
            Document document = Jsoup.parse(html, HOST);
            Element postForm = document.getElementById("fastpostform");
            if(!postForm.toString().contains("您现在无权发帖")){
                content = new ReplayContent();
                content.setUrl(url);
                
                log.debug(postForm.attr("abs:action"));
                content.setAction(postForm.attr("abs:action"));
                
                
                ////////
                Elements teElements = document.select("td[id^=postmessage_]");
                String message = "";
                for(int i=0;i<teElements.size();i++){
                    String temp = teElements.get(i).html().replaceAll( "(?is)<.*?>", "");
                    if(temp.contains("发表于")){
                        String[] me = temp.split("\\s+");
                        temp = me[me.length-1];
                    }
                    message+=temp.replaceAll("\\s+", "");
                }
                log.debug(message.replaceAll("\\s+", ""));
                ///////////////
                /*取最后一条评论
                Element messageElement= document.select("td[id^=postmessage_]").last();
//                String message = messageElement.html().replaceAll("\\&[a-zA-Z]{1,10};", "").replaceAll("<[^>]*>", "").replaceAll("[(/>)<]", "");
                String message = messageElement.html().replaceAll( "(?is)<.*?>", "");
                */
                if(message.contains("发表于")){
                    String[] me = message.split("\\s+");
                    message = me[me.length-1];
                }
                content.setMessage(message.replaceAll("&nbsp;", "").replaceAll("上传", "").replaceAll("附件", "").replaceAll("下载", ""));
                Elements inputs = postForm.getElementsByTag("input");
                for(Element input:inputs){
                    log.debug(input.attr("name")+":"+input.attr("value"));
                    if(input.attr("name").equals("posttime")){
                        content.setPosttime(input.attr("value"));
                    }else if(input.attr("name").equals("formhash")){
                        content.setFormhash(input.attr("value"));
                    }else if(input.attr("name").equals("usesig")){
                        content.setUsesig(input.attr("value"));
                    }else if(input.attr("name").equals("subject")){

当然这只适用于没有验证码的论坛对于有验证码的只能绕道了,

灌水有害,经过一番轰炸这就是结果QQ截图20140109224028

对于回复内容刚开始只取了当前帖子内最后一条评论然后进行回复,被警告!然后使用IK分词获取关键字代码是贴来的请移步

参考连接:

缺点:没有使用多线程、没有进行充分测试

代码整理中尽快提供

后期计划:加入签到、做任务功能、把@1循环改为自动发现

小弟第一次发帖其中有不足之处望批评指正
