vue-------滑动验证

 

 

 

 

 

 

需要写一个滑动验证是否为本人操作,框架用的是vue的elementui,

逻辑是,通过后端的接口取出来相应的大图和小图展示到布局中,然后判断滑行距离(误差十像素之内)

有需要的可以私信我

放上代码供参考:  

 

<template>  
  <div>

需要在main.js中配置是否请求携带cookie

 
// 请求是否携带cookie
axios.defaults.withCredentials=true;

 

接口文档:(删除了主要部分但是参数都在)

参数    没有参数

请求方式    get
返回参数    Errcode:错误码,如果为零没有错误
smallImage:要拖动的小图片的base64
bigImage:大图的base64
Errmsg:错误消息返回success则为获取成功
yHeight:图片距离下边框的高度
