登录验证码无痕验证

文档链接
https://help.aliyun.com/document_detail/122237.html?spm=a2c4g.11186623.6.576.5b6251b3FrkgHe

具体：
首先index.html加入代码

 <script src="//g.alicdn.com/mtb/lib-flexible/0.3.4/??flexible_css.js,flexible.js"></script>

然后在输入框代码组件里引入无痕验证的组件

 <NoCaptcha ref="captcha" />

在发验证码前调用组件方法

 this.$refs.captcha.handleCaptcha(params).then(res => {

组件代码如下

/* eslint-disable */
<template>
  <div class="no-captcha-wrap">
    <van-dialog v-model="captchaVisible" :show-confirm-button=false overlay-class="captVisi">
      <div slot="title" class="captHeader">
        <span>请完成安全验证</span>
        <img @click="captchaVisible = false" src="../../assets/images/capeClose.png" alt="">
      </div>
      <div id="captcha"></div>
    </van-dialog>
  </div>
</template>
