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

			waitWebElement(driver, By.id("code"), 500).click();
			Thread.sleep(100);
			// 获取到验证区域

			// 获取滑动按钮
			WebElement moveElemet = waitWebElement(driver, By.id("tcaptcha_drag_button"), 500);
