Java支付宝身份认证对接WEB

一.支付宝创建应用后会得到APP_ID、接着弄公钥、私钥以及前面方式（RSA、RSA2).

二.js

 <div id="renop2" style="width: 60%;margin-left: 59px;margin-top: 22px;"></div>
    
<script>

  //js页面生成二维码
  jQuery('#renop2').qrcode({
    
    
       width: 250,
       height: 250,
       text: data.data.url
       });
</script>
