一个PHP文件搞定支付宝系列之手机网站支付（兼容微信浏览器）

来源：互联网发布：c 串口通信编程编辑：程序博客网时间：2024/04/26 09:29

网上的很多PHP支付宝支付接入教程都颇为复杂，且需要配置和引入较多的文件，本人通过整理后给出一个单文件版的，希望可以给各位想接入支付宝支付的带来些许帮助和借鉴意义。

一个PHP文件搞定微信支付系列：https://github.com/dedemao/weixinPay

在手机浏览器下打开实现效果

这里写图片描述

在微信中打开实现效果

这里写图片描述

注：兼容微信浏览器需依赖支付宝官方提供的demo（alipay_in_weixin_demo）中的两个文件，即：ap.js及pay.htm

环境依赖

PHP5.0以上，且需要开启CURL服务、SSL服务。

如需兼容微信浏览器，还需依赖ap.js及pay.htm。

注意事项

1.文件开头的配置信息必须完善
2.商户私钥需填写对应签名算法类型的私钥，如何生成密钥参考：
2.1 https://docs.open.alipay.com/291/105971
2.2 https://docs.open.alipay.com/200/105310
