Java模拟HTTP Get Post请求实现论坛自动回帖功能
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++) {
postMesshttp://age(startId);
startId++;
}
}
public static void postMessage(int id) {
if (!isExist(id)) {
return;
}
String tmpPath = baseRefer + id;
StringBuilder path = new StringBuilder(tmpPath);
Map
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
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();
}
}
