上次发了博客
腾讯防水墙滑动验证码破解
之后有人问我：

腾讯防水墙滑动验证码破解 https://open.captcha.qq.com/online.html

有人问我
博主你好，试过你的代码，可以跑通，但是这个网站的防水墙无法验证通过https://urlsec.qq.com/report.html 我使用webdriver.Chrome()打开该网站后，手动拖动验证码仍然失效… 不知道啥原因
我看了下
的确会出现这种情况，我刚开始猜：估计腾讯这个网页开启了window.navigator.webdriver 验证
但是后来我发现应该不是webdriver验证的问题，应该是鼠标轨迹，滑动轨迹有什么特殊的判断吧，目前还不是很清楚。
这里写一了一个循环滑动，直至滑动成功的脚本。
之后如果有更好的解决方案了再看看吧。
