前言

本文是结合第三方demo提供，然后整理的代码，主要涉及的接口有，签约，支付，流程是，用户输入身份证、银行卡等信息，调用平台接口，返回url，在url发送短信确认签约，然后异步回调确认是否签约，
成功则返回唯一标识，然后通过唯一标识调用支付接口，进行支付。

签约效果

签约前如果不传入个人信息等，可以直接在此页面填入，如果传入则不能更改

官网文档

汇付宝开发文档

问题

1. 测试环境没有问题，正式环境有问题
   请求url有问题，例如：商户与支付平台使用www.baidu.com地址进行授权签约，而平台使用的是api.baidu.com，这样就会造成这个问题，解决方案就是：解析api.baidu.com
