支付宝关闭退款功能（支付宝退款背后的秘密）
支付宝关闭退款功能（支付宝退款背后的秘密）
官方接口文档：
退款接口：https://opendocs.alipay.com/apis/api_1/alipay.trade.refund
支付订单查询接口：https://opendocs.alipay.com/apis/api_1/alipay.trade.query
示例代码如下：
<?php
/**
* 扫码支付
* 提醒：提交支付请求后微信会同步返回支付结果（没有异步回调通知）。当返回结果为“系统错误”时，商户系统等待5秒后调用【查询订单API】，查询支付实际交易结果；当返回结果为“USERPAYING”时，商户系统可设置间隔时间(建议10秒)重新查询支付结果，直到支付成功或超时(建议30秒)；
