下载煎蛋无聊图

昨天在网上想找一个下载jandan 里无聊图的工具。没有找到java版的。就写了一个简单的下载无聊图的代码。

public class jandan {
    // 煎蛋无聊图的地址 也可以换成是妹子图
    // 妹子图URL：http://jandan/ooxx
    public String jandan="http://jandan/pic";
    // 煎蛋页码url后缀
    public  String prfix ="/page-@#comments";
    // 图片保存路径，必须是存在的路径
    public String downLoadPath="d:\\jandan\\gaoxiao\\";
    // 无聊图开始页码
    public int currentPage = 855;
    // 图片的url
    private ArrayList<String> result = new ArrayList<String>();

    private void  analyse(int page){
        try {
        URL url = new URL(jandan+prfix.replace("@",page+""));
        URLConnection conn = url.openConnection();
        conn.setDoOutput(true);
        InputStream in = null;
        in = url.openStream();
        String content = pipe(in,"utf-8");
        String[] imgs = content.split("<img");
            ArrayList<String> tmp = new ArrayList<String>();
             int i=1;
              //html: *****<img> ******<img >,偶数为img 中含有src的字串
              for(String str:imgs){
                if(i%2==0){
                    tmp.add(str.split("src=\"")[1]);
                }
                i++;
               }
            for(String str:tmp){
                String sp =  str.split("\"")[0];
                if(sp.indexOf("http")==0){
                    result.add(sp);
                }
            }
        } catch (Exception e) {
        e.printStackTrace();
        }
    }


    private String pipe(InputStream in,String charset) throws IOException {
        StringBuffer s = new StringBuffer();
        if(charset==null||"".equals(charset)){
        	charset="utf-8";
        }
        String rLine = null;
        BufferedReader bReader = new BufferedReader(new InputStreamReader(in,charset));

        while ( (rLine = bReader.readLine()) != null) {
            String tmp_rLine = rLine;
            int str_len = tmp_rLine.length();
            if (str_len > 0) {
              s.append(tmp_rLine);
            }
            tmp_rLine = null;
       }
        in.close();
        return s.toString();
}
         public void download(){
             for(int i=currentPage;i>0;i--){
             analyse(i);
             for(String path:result){
             URL url = null;
             try {
                  // 生成图片名
                int index = path.lastIndexOf("/");
                String sName = path.substring(index+1, path.length()).replace("?","4");
                // 存放地址
                File img = new File(downLoadPath+sName);
                // 如果图片存在或者图片URL中包含以下网址则返回
                // 屏蔽几个无法访问的地址加快图片的下载速度
                if(img.exists() || path.indexOf("http://www.gravatar")>-1 || path.indexOf("http://www.dxbzyw/")>-1
                        || path.indexOf("http://24.media.tumblr")>-1 || path.indexOf("staticflickr")>-1) continue;
                BufferedInputStream in = new BufferedInputStream(new URL(path).openStream());
                System.out.println(path);
                // 生成图片
                BufferedOutputStream out = new BufferedOutputStream(
                        new FileOutputStream(img));
                byte[] buf = new byte[2048];
                int length = in.read(buf);
                while (length != -1) {
                    out.write(buf, 0, length);
                    length = in.read(buf);
                }
                in.close();
                out.close();
             } catch (Exception e) {
                 e.printStackTrace();
             }
              }
                 result=null;
                 result = new ArrayList<String>();
                 try {
                     // 线程休息10秒 
                     Thread.sleep(1000*10);
                 } catch (InterruptedException e) {
                     e.printStackTrace();
                 }
             }
         }

}

下载图片方法

public class download {

    public static void main(String[]a){
        jandan f = new jandan ();
        f.download();
    }
}
