[PHP知识库]PHP对接农行快e通授权登录

开发文档地址：
https://openbank.abchina.com/Portal/serIntroduced/fastEtransfer.html

授权登录农行暂时是没有php版本，而且文档中API参数没有说明，示例传参有一些错误，下面我就来说说我遇到的坑

1.一般授权登录需要获取用户信息，首先要进行一下两步（具体获取看开发文档）:

1.获取Authorization Code
2.通过Authorization Code获取Access Token

2.通过AccessToken获取用户的个人信息 ：

访问资源服务器的接口使用方法，在访问特定的接口时需要在Header头部加入Authorization，值为”Bearer accessToken” 。

“encrypt_data”: “ENCRYPTDATA”,encrypt_data这个参数不是要你传 "encrypt_data"这个值，是传biz_data使用AES加密后的字符串

AES具体加密请查看我上一篇文章

代码详细说明请求接口参数传递加密及返回参数解密
