为什么要加验证码？
验证码（CAPTCHA）是 Completely Automated Public Turing test to tell Computers and Humans Apart的缩写。是一种区分用户是计算机还是人的公共全自动程序。可以防止：恶意破解密码、刷票、论坛灌水，有效防止某个黑客对某一个特定注册用户用特定程序暴力破解方式进行不断的登陆尝试，实际上用验证码是现在很多网站通行的方式，我们利用比较简易的方式实现了这个功能。 有效制止大多数的恶意请求，减轻服务端的压力，可以有效的区分有效请求和无效请求。
常见的验证码方式
- 点击按钮通过验证
- 滑动拼图验证
- 文字点选
- 图标点选
- 推理拼图
- 语序点选
- 语音验证 当然还有其他的方式这里就不一一列举了今天我们这里主要说一下滑块验证
