PHP 支付宝(单笔转账到银行账户接口)

alipay.fund.trans.tobank.transfer(单笔转账到银行账户接口)

小程序文档 - 支付宝文档中心

一、下载支付宝SDK，现有版本v1、v2、v3

https://github.com/alipay/alipay-sdk-php-all

github 慢的话，DNS   直达即可 140.82.112.3 github.com

【host文件路径c:\windows\system32\drivers\etc】

二、引用代码编写

回调的时候，默认签名使用的是 rsaCheckV1

暂时还没有碰到 rsaCheckV2 的，本来我以为我发送的是V2版本的签名，回调也是V2的

后面试了又试，rsaCheckV1 无疑了

支付宝的SDK无疑是很完善的，接入也方便很多

这里使用的是V2版本
