import java.io.*;
import java.net.*;
public class Yugi {
    public static String resolveHTML(String spec, String charsetName) {
        try {
            URL url = new URL(spec);
            HttpURLConnection huc = (HttpURLConnection) url.openConnection();
            InputStreamReader isr = new InputStreamReader(huc.getInputStream(), charsetName);
            BufferedReader br = new BufferedReader(isr);
            StringBuilder builder = new StringBuilder();
            String line = null;
            while (null != (line = br.readLine())) {
                builder.append(line);
            }
            br.close();
            isr.close();
            huc.disconnect();
            return builder.toString();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    public static void main(String[] args){
        int page = 1;
        String prev= "ht防止tp://v.m.zjxuexi.com/a/archiver/?tid-21.html&page=";
        String url = prev + page;
        String str = "";
        String result = "";
        while((result = resolveHTML(url, "utf-8")).length() != str.length()){
           url = prev + (++page);
           str = result;
           System.out.println(result);
        }
    }
}

追问这和我的问题好像没什么关系

追答你不是要获取每个页面的内容么

你不是要取么

你之前的那几个问题不都透露了么

还来忽悠我

我打印出来3行，说明就是最大页码了，还要别人来说明

真是一点觉悟都没有，采纳即可

不采纳，就加你到诚信的黑名单
