Php 贝宝支付集成
我已经将paypal支付集成到了我的网站中,但代码非常基本,我对它的安全性没有信心,因此我开始寻找一种更安全、更复杂的paypal集成代码,最近偶然发现了这一代码,问题是,我只理解notify/listener.php中的部分代码,我希望有人能真正地将其分解,并用更简单的术语解释,例如,我不理解脚本中的get magic quotes部分Php 贝宝支付集成,php,paypal,Php,Paypal,我已经将paypal支付集成到了我的网站中,但代码非常基本,我对它的安全性没有信心,因此我开始寻找一种更安全、更复杂的paypal集成代码,最近偶然发现了这一代码,问题是,我只理解notify/listener.php中的部分代码,我希望有人能真正地将其分解,并用更简单的术语解释,例如,我不理解脚本中的get magic quotes部分 // CONFIG: Enable debug mode.

不要使用那些代码中的任何东西,它非常旧 下面是一个更好的HTML/JS基本支付示例: Jist:
PayPal智能支付按钮集成|客户端演示
//将PayPal按钮渲染到#PayPal按钮容器中
贝宝,按钮({
//设置事务
createOrder:函数(数据、操作){
return actions.order.create({
购买单位:[{
金额:{
值:“88.44”
}
}]
});
},
//完成交易
onApprove:功能(数据、操作){
返回actions.order.capture().then(函数(详细信息){
//向买家显示成功消息
警报(“+details.payer.name.given_name+”!”完成的交易);
});
}
}).render(“#贝宝按钮容器”);
此jist在撰写本文时会随着时间的推移而衰减,请始终咨询开发人员paypal客户端集成门户演练以了解最新的示例。“我不理解获取魔法报价部分”。。。也许最好的情况是,这些垃圾已经消失多年了。此脚本看起来已经过时,非常危险。虽然此链接可以回答问题,但最好在此处包含答案的基本部分,并提供链接供参考。如果链接页面发生更改,则仅链接的答案可能无效-
