滑块验证码识别 java版本
来源：互联网 发布：jsp和javascript的用途 编辑：程序博客网 时间：2024/05/21 22:48
好久没有更新技术文章了，很久之前研究过滑块验证码的破解，照着别人的代码改，将其他版本的代码改成java的，加上自己的一些研究，凑合凑合出了第一个java版本的，此版本不是控制浏览器进行验证，纯java控制（包含java js引擎执行js），目前都完成了，只是滑动轨迹的生成被后台识别出是机器人，除了这个问题以外，其他的均没有任何问题！如果谁能弄出轨迹算法出来，可以留言或者加我qq：1069478446，不胜感激
废话不多说，自己上代码：

private ArrayList<int[]> generate(int xpos) { System.out.println(xpos); int sx = rnd.nextInt(15)-25; int sy = rnd.nextInt(15)-25; ArrayList<int[]> arr = new ArrayList<int[]>(); arr.add(new int[] { sx, sy, 0 }); int maxCount = 300; // max len 100 double x = 0; double lx = xpos - x; while (Math.abs(lx) > 0.8 && maxCount-- > 0) { double rn = rnd.nextDouble(); double dx = rn * lx * 0.6; if (Math.abs(dx) < 0.5) continue; double dt = rnd.nextDouble() * (rn * 80 + 50)+ 10; rn = rnd.nextDouble(); double dy = 0; if (rn < 0.2 && dx > 10) // { dy = rn * 20.0; if (rn < 0.05) dy = -rn * 80; } x += dx; arr.add(new int[] { (int)(dx + 0.5), (int)(dy + 0.5), (int)(dt + 0.5) }); lx = xpos - x; } double dtlast = 500.0 * rnd.nextDouble() + 100.0; arr.add(new int[] { -1, 0, (int)(dtlast) }); return arr; }来算的，目前识别率很低，不到1%
由哪个大神能提供轨迹算法，不胜感激，但是前提是不是使用保存下来的轨迹
