### php achieve Alipay online payment and payment demo scan code
Background: The increase in the number when making a public h5 end, you need to pay for access, non-micro-channel environment, chose to implement under Alipay, the following simple recording process, and do a simple package that can be used to use, Note: This item only based on the official demo modify, you need access to need to get their own projects demand.
The demo github Address: https://github.com/alisleepy/alipay
Directory Structure:
The following file directory without modification, only modify configuration files and paytest.php config.php file and create_qrcode.php
/aop //核心库
/img //二维码中心的icon（自己引入的）
/lib //核心库
/lotusphp_runtime //没用到
/phpqrcode //生成二维码的插件（扫码支付时自己引入的，没用官方的）
/service //官方demo的测试文件（没用到）
AopSdk.php //demo项目入口文件，不用修改
config.php //重要，存放配置文件
create_qrcode.php //二维码扫码支付demo
notify_url.php //异步回调地址（只测试了支付，没用到）
paytest.php //在线支付demo
return_url.php //同步跳转地址（没用到）step:
- Alipay application developers
- Create a sandbox application, access to appId
- Obtain public keys and other information, modify config.php
- Modify the file functions to achieve pay
Online payment code: paytest.php

The end is to obtain public keys this section must not be wrong, if there is demand in the real project introduced sdk files, but aop, lotusphp_runtime both folders Alipay core library must be introduced, AopSdk.php is the entry file It must be introduced
