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、
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
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：
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：
输入错误的用户名和密码会发现实际登录地址为 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
{"result":true,"redirect":[]} 直接输入rediret连接和正常登录
获取跳转链接：
private LoginResult getRedirectUrl(){ LoginResult loginResult = null; CloseableHttpClient httpClient = HttpClients.createDefault(); HttpPost httpost = new HttpPost(LOGINURL); httpost.setHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8"); httpost.setHeader("Accept-Language", "zh-CN,zh;q=0.8"); httpost.setHeader("Cache-Control", "max-age=0"); httpost.setHeader("Connection", "keep-alive"); httpost.setHeader("Host", "passport.dakele.com"); httpost.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"); List nvps = new ArrayList (); nvps.add(new BasicNameValuePair("product", "bbs")); nvps.add(new BasicNameValuePair("surl", "http://bbs.dakele.com/")); nvps.add(new BasicNameValuePair("username", "yourname"));//用户名 nvps.add(new BasicNameValuePair("password", "yourpass"));//密码 nvps.add(new BasicNameValuePair("remember", "0")); httpost.setEntity(new UrlEncodedFormEntity(nvps, Consts.UTF_8)); CloseableHttpResponse response2 = null; try { response2 = httpClient.execute(httpost); if(response2.getStatusLine().getStatusCode()==200){ HttpEntity entity = response2.getEntity(); String entityString = EntityUtils.toString(entity); JSONArray jsonArray = JSONArray.fromObject("["+entityString+"]"); JsonConfig jsonConfig=new JsonConfig(); jsonConfig.setArrayMode(JsonConfig.MODE_OBJECT_ARRAY); jsonConfig.setRootClass(LoginResult.class); LoginResult[] results= (LoginResult[]) JSONSerializer.toJava( jsonArray, jsonConfig ); if(results.length==1){ loginResult = results[0]; } } } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }finally{ try { response2.close(); httpClient.close(); } catch (IOException e) { e.printStackTrace(); } } return loginResult; } 登录代码：
public boolean login(){ boolean flag = false; LoginResult loginResult = getRedirectUrl(); if(loginResult.getResult().equals("true")){ cookieStore = new BasicCookieStore(); globalClient = HttpClients.custom().setDefaultCookieStore(cookieStore).build(); HttpGet httpGet = new HttpGet(loginResult.getRedirect()); httpGet.setHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8"); httpGet.setHeader("Accept-Language", "zh-CN,zh;q=0.8"); httpGet.setHeader("Connection", "keep-alive"); httpGet.setHeader("Host", HOST); httpGet.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 { globalClient.execute(httpGet); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } List cookies2 = cookieStore.getCookies(); if (cookies2.isEmpty()) { log.error("cookie is empty"); } else { for (int i = 0; i < cookies2.size(); i++) { } } } return flag; } 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
for(int i=1;i<200;i++){ String basurl="http://bbs.dakele.com/forum-43-"+i+".html"; log.info(basurl); List 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); } } } 在列表页内获取帖子地址：
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 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
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 ", ""); 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(" ", "").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")){ content.setSubject(input.attr("value")); } } }else{ log.warn("您现在无权发帖:"+url); } } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return content; } 地址有了，内容有了接下来开始放水了
public void replay(ReplayContent content){ HttpPost httpost = new HttpPost(content.getAction()); httpost.setHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8"); httpost.setHeader("Accept-Language", "zh-CN,zh;q=0.8"); httpost.setHeader("Cache-Control", "max-age=0"); httpost.setHeader("Connection", "keep-alive"); httpost.setHeader("Host", HOST); httpost.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"); List nvps = new ArrayList (); nvps.add(new BasicNameValuePair("posttime", content.getPosttime())); nvps.add(new BasicNameValuePair("formhash", content.getFormhash())); nvps.add(new BasicNameValuePair("usesig", content.getUsesig())); nvps.add(new BasicNameValuePair("subject", content.getSubject())); nvps.add(new BasicNameValuePair("message", content.getMessage())); httpost.setEntity(new UrlEncodedFormEntity(nvps, Consts.UTF_8)); //HTTP 三次握手 必须处理响应刚开始没注意卡在这了 CloseableHttpResponse response2 = null; try { response2 = globalClient.execute(httpost); //log.info(content.getAction()); //log.info(content.getMessage()); HttpEntity entity = response2.getEntity(); EntityUtils.consume(entity);// BufferedWriter bw= new BufferedWriter(new FileWriter("d:/tt1.html"));// bw.write(EntityUtils.toString(response2.getEntity()));// bw.flush();// bw.close(); //System.out.println(EntityUtils.toString(response2.getEntity())); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } 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
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
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

早上把代码整理了下，现在分享给大家，直接对Myeclipse工程进行的打包解压后可直接导入
