Java HttpURLConnection 下载图片 图片全是“加密图片”文字

Question

如题
想从QQ空间里批量下载图片
代码                URL url = new URL(surl);
                HttpURLConnection uc = (HttpURLConnection)url.openConnection();
                
                InputStream is = uc.getInputStream();
                
                FileOutputStream fs = new FileOutputStream(".\\workspace\\result" + "\\" + FileIdMgr.mgr.getId() + Conf.conf.filestyle);
                
                byte[] buf = new byte[1024];
                int c = 0;
                while((c = is.read(buf)) > 0){
                    fs.write(buf, 0, c);
                }
                
                fs.close();
                
                is.close();
                uc.disconnect();

Answer 1

有认证的，你打开ＱＱ空间再F12查看一下cookie把里面的key,value全部复杂出来，然后setProperty到connection中就可以了
