PHP搞定支付宝WAP手机网站支付

开工大吉,早上在公司开了一个多小时会,老板还发了开工红包,趁着中午没事就接着前段时间的一个PHP文件搞定微信H5支付再来一篇总结PHP文件搞定支付宝WAP网站支付。此支付方式为调起手机支付宝客户端支付,如果没有安装支付宝客户端则进入支付宝网页收银台进行支付。

环境依赖

PHP5.0以上,且需要开启CURL服务、SSL服务。

业务功能

适用于商家在移动端网页应用中集成支付宝支付功能。

商家在网页中调用支付宝提供的网页支付接口调起支付宝客户端内的支付模块,商家网页会跳转到支付宝中完成支付,支付完后跳回到商家网页内,最后展示支付结果。若无法唤起支付宝客户端,则在一定的时间后会自动进入网页支付流程。

代码实现

此处省略申请信息步骤,直接上代码了。

 //程序执行完后必须打印输出“success”(不包含引号)。如果商户反馈给支付宝的字符不是success这7个字符,支付宝服务器会不断重发通知,直到超过24小时22分钟。一般情况下,25小时以内完成8次通知(通知的间隔频率一般是:4m,10m,10m,1h,2h,6h,15h);
 echo 'success';exit();
