vue仿淘宝滑动验证码功能(样式模仿)

我们知道验证码的目的 是为了验证到底是人还是机器。

淘宝滑动验证码会采集用户的操作数据，环境数据等等，通过算法加密成一个字符串，提交到服务器分析，判断是不是人工在操作。

我这里写的只是模仿了样式，并没有进行那些复杂的操作，所以并不安全（不能判断人还是机器）。

因为touch事件和mouse事件不同，和获取clientx在移动端和pc端也不同！！！所以分两端

下面有pc端和移动端！！！（2019-03-12更新）

本文基于vue，引入下面组件 可以直接使用

1、实际效果

2、pc端！！！ vue组件（下面是一个vue组件，可以引入直接使用）
