图片抓取

简单图片抓取，Java实现

public void getpic(String src,String num,int loc,String alt,String category,String name) {
        int id = Integer.parseInt(num);
        int id1 = id/1000000;
        int id2 = id/1000;
        String path ="F:\\image\\"+id1+"\\"+id2+"\\"+num+"\\";
        File cate = new File(path);
        if (!cate.exists()&&!cate.isDirectory()) {
            cate.mkdirs();
        }
        String target = path+loc+".png";
        File file = new File(target);
        //System.out.println("url "+src);

        //System.out.println(target);

        try {
            URL url = new URL(src);
            HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
            InputStream inputStream=httpURLConnection.getInputStream();
            byte[] bs = new byte[1024];
            int len;
            OutputStream outputStream = new FileOutputStream(file, true);
            while ((len=inputStream.read(bs))!=-1) {
                outputStream.write(bs, 0, len);
            }
            outputStream.close();
            inputStream.close();
            httpURLConnection.disconnect();
            BufferedImage bufferedImage = ImageIO.read(file);
            int width = bufferedImage.getWidth();
            int height = bufferedImage.getHeight();
                    } catch (Exception e) {
            // TODO: handle exception

             //e.printStackTrace();

            return ;
        }
    }
