* 验证码地址：/online.html* 使用OpenCv模板匹配* 成功率90%左右* Java + Selenium + OpenCV

产品样例

来吧！展示！

注意！！！

·在模拟滑动时不能按照相同速度或者过快的速度滑动，需要向人滑动时一样先快后慢，这样才不容易被识别。

模拟滑动代码↓↓↓

/*** 模拟人工移动* @param driver* @param element页面滑块* @param distance需要移动距离*/public static void move(WebDriver driver, WebElement element, int distance) throws InterruptedException {int randomTime = 0;if (distance > 90) {randomTime = 250;} else if (distance > 80 && distance <= 90) {randomTime = 150;}List<Integer> track = getMoveTrack(distance - 2);int moveY = 1;try {Actions actions = new Actions(driver);actions.clickAndHold(element).perform();Thread.sleep(200);for (int i = 0; i < track.size(); i++) {actions.moveByOffset(track.get(i), moveY).perform();Thread.sleep(new Random().nextInt(300) + randomTime);}Thread.sleep(200);actions.release(element).perform();} catch (Exception e) {e.printStackTrace();}}/*** 根据距离获取滑动轨迹* @param distance需要移动的距离* @return*/public static List<Integer> getMoveTrack(int distance) {List<Integer> track = new ArrayList<>();// 移动轨迹Random random = new Random();int current = 0;// 已经移动的距离int mid = (int) distance * 4 / 5;// 减速阈值int a = 0;int move = 0;// 每次循环移动的距离while (true) {a = random.nextInt(10);if (current <= mid) {move += a;// 不断加速} else {move -= a;}if ((current + move) < distance) {track.add(move);} else {track.add(distance - current);break;}current += move;}return track;}

看操作，no bb，直接上代码
