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

{"result":true,"redirect":http://bbs.dakele.com/member.php?mod=logging&action=login&loginsubmit=yes&infloat=yes&lssubmit=yes&inajax=0&fastloginfield=username&quickforward=yes&handlekey=ls&cookietime=2592000&remember=0&username=youname&AccessKey=[]}

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 <NameValuePair> nvps = new ArrayList <NameValuePair>();
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<Cookie> 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@1

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);
}
}
}

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<elements.size();i++){
Element e = elements.get(i);
urList.add(e.attr("abs:href"));
}

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<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(" ", "").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 <NameValuePair> nvps = new ArrayList <NameValuePair>();
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请移步

参考连接：

我为开源做贡献，网页正文提取

Jsoup使用选择器语法来查找元素

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
