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。

在手机浏览器下打开实现效果

在微信中打开实现效果

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

代码

<?php

header('Content-type:text/html; Charset=utf-8');

$appid = 'xxxxx';  //https://open.alipay.com 账户中心->密钥管理->开放平台密钥,填写添加了电脑网站支付的应用的APPID

$returnUrl = 'http://www.xxx.com/alipay/return.php';     //付款成功后的同步回调地址

$notifyUrl = 'http://www.xxx.com/alipay/notify.php';     //付款成功后的异步回调地址

$outTradeNo = uniqid();     //你自己的商品订单号

$payAmount = 0.01;          //付款金额,单位:元

$orderName = '支付测试';    //订单标题

$signType = 'RSA2';       //签名算法类型,支持RSA2和RSA,推荐使用RSA2

//商户私钥,填写对应签名算法类型的私钥,如何生成密钥参考:https://docs.open.alipay.com/291/105971和https://docs.open.alipay.com/200/105310
