这里有新鲜出炉的Java并发编程示例,程序狗速度看过来!
java 是一种可以撰写跨平台应用软件的面向对象的程序设计语言,是由Sun Microsystems公司于1995年5月推出的Java程序设计语言和Java平台(即JavaEE(j2ee), JavaME(j2me), JavaSE(j2se))的总称。
这篇文章主要介绍了Java模拟HTTP Get Post请求实现论坛自动回帖功能,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
最近想自动发帖回帖,拿某论坛试验了一下,发现可行,不过后续没有再使用,以免影响论坛正常运行。
1、帖子链接的格式为
http://bbs.***.***.**/forum.php?mod=viewthread&tid=774210
最后面774210数字变化, 就可以得到不同的帖子
2、防止帖子发表会又被删了的情况, 进行判断帖子是否存在
3、递增后面的 id 数字, 对每个链接做回帖的 POST 请求
重难点
回帖需要用户登录信息
一种是利用Cookie
另一种是进行模拟登录
本文采用前者
判断 url 对应的帖子是否存在
有可能用户发了帖子,比如 url 为 http://bbs.***.***.**/forum.php?mod=viewthread&tid=774200
后来该帖子用户删除了或者被管理员删除了,虽然帖子不在了,但是该 tid=774200 还是存在的
- public static boolean isExist(int id) {
- String tmpPath = baseRefer + id;
- URL url;
- try {
- url = new URL(tmpPath);
- HttpURLConnection con = (HttpURLConnection) url.openConnection();
- con.addRequestProperty("Content-Type", "text/html; charset=UTF-8");
- con.addRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1) ApplewebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.104 Safari/537.36");
- con.addRequestProperty("Referer", "http://t.dianping.com/register");
- con.setRequestMethod("GET");
- if (con.getResponseCode() == 200) {
- InputStream inputStr = con.getInputStream();
- String info = new String(StreamTool.read(inputStr), "UTF-8");
- if (info.contains("抱歉,指定的主题不存在或已被删除或正在被审核")) {
- System.out.println("id=" + id + "帖子存在或已被删除!");
- return false;
- }
- }
- } catch(MalformedURLException e) {
- // TODO Auto-generated catch block
- e.printStackTrace();
- } catch(IOException e) {
- // TODO Auto-generated catch block
- e.printStackTrace();
- } catch(Exception e) {
- // TODO Auto-generated catch block
- e.printStackTrace();
- }
- return true;
- }
模拟发帖
代码比较简单,注意事项是找到自己的Cookie,赋给String yourCookeie
用post发送一个回帖,回帖信息在 mapData.put("message", "友情帮顶了") 中
- private static final String baseRefer = "http://bbs.**.**.**/forum.php?mod=viewthread&tid=";
- private static final String yourCookeie = "Q8qA_2132_saltkey=**; Q8qA_2132_lastvisit=****3699;";
- public static void main(String[] args) {
- int startId = 774210; // you need change
- for (int i = 0; i < 100; i++) {
- postMessage(startId);
- startId++;
- }
- }
- public static void postMessage(int id) {
- if (!isExist(id)) {
- return;
- }
- String tmpPath = baseRefer + id;
- StringBuilder path = new StringBuilder(tmpPath);
- Map < String,
- String > mapData = new LinkedHashMap < String,
- String > ();
- mapData.put("mod", "post");
- mapData.put("action", "reply");
- mapData.put("replysubmit", "yes");
- mapData.put("infloat", "yes");
- mapData.put("handlekey", "fastpost");
- mapData.put("inajax", "1");
- mapData.put("message", "友情帮顶了");
- mapData.put("formhash", "86ec5d81");
- try {
- for (Map.Entry < String, String > mapEnt: mapData.entrySet()) {
- path.append("&");
- path.append(mapEnt.getKey() + "=");
- path.append(URLEncoder.encode(mapEnt.getValue(), "UTF-8"));
- }
- URL url = new URL(path.toString());
- HttpURLConnection con = (HttpURLConnection) url.openConnection();
- con.setRequestMethod("POST");
- con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
- con.setRequestProperty("Content-Length", String.valueOf(path.length()));
- con.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.104 Safari/537.36");
- con.setRequestProperty("Cookie", yourCookeie);
- con.setDoOutput(true);
- OutputStream outStr = con.getOutputStream();
- outStr.write(path.toString().getBytes());
- if (con.getResponseCode() == 200) {
- InputStream inputStr = con.getInputStream();
- String info = new String(StreamTool.read(inputStr), "UTF-8");
- System.out.println("在id=" + id + "成功发帖!");
- try {
- Thread.sleep(20 * 1000);
- } catch(InterruptedException e) {
- // TODO Auto-generated catch block
- e.printStackTrace();
- }
- }
- } catch(UnsupportedEncodingException e) {
- // TODO Auto-generated catch block
- e.printStackTrace();
- } catch(MalformedURLException e) {
- // TODO Auto-generated catch block
- e.printStackTrace();
- } catch(IOException e) {
- // TODO Auto-generated catch block
- e.printStackTrace();
- } catch(Exception e) {
- // TODO Auto-generated catch block
- e.printStackTrace();
- }
- }
还有一个工具方法,将输入流转化为字节
- class StreamTool {
- public static byte[] read(InputStream inputStr) throws Exception {
- ByteArrayOutputStream outStr = new ByteArrayOutputStream();
- // TODO Auto-generated method stub
- byte[] buffer = new byte[1024];
- int len = 0;
- while ((len = inputStr.read(buffer)) != -1) {
- outStr.write(buffer, 0, len);
- }
- inputStr.close();
- return outStr.toByteArray();
- }
- }
效果图:
