简单整理一下PHP项目整合PayPal支付功能。
一、表单的构建:
<span><</span><span>form </span><span>method</span><span>="post"</span><span> name</span><span>="form"</span><span> action</span><span>="https://www.paypal.com/cgi-bin/webscr"</span><span>></span> <span><</span><span>input </span><span>type</span><span>="hidden"</span><span> name</span><span>="rm"</span><span> value</span><span>="2"</span><span>/></span> <span><</span><span>input </span><span>type</span><span>="hidden"</span><span> name</span><span>="cmd"</span><span> value</span><span>="_xclick"</span><span>/></span> <span><</span><span>input </span><span>type</span><span>="hidden"</span><span> name</span><span>="business"</span><span> value</span><span>="商家账号"</span><span>/></span> <span><</span><span>input </span><span>type</span><span>="hidden"</span><span> name</span><span>="return"</span><span> value</span><span>="返回网址"</span><span>/></span> <span><</span><span>input </span><span>type</span><span>="hidden"</span><span> name</span><span>="cancel_return"</span><span> value</span><span>="取消返回网址"</span><span>/></span> <span><</span><span>input </span><span>type</span><span>="hidden"</span><span> name</span><span>="notify_url"</span><span> value</span><span>="用于接收PayPal发送的即时付款通知的URL,必须是有效的URL"</span><span>/></span> <span><</span><span>input </span><span>type</span><span>="hidden"</span><span> name</span><span>="item_name"</span><span> value</span><span>="物品名称"</span><span>/></span> <span><</span><span>input </span><span>type</span><span>="hidden"</span><span> name</span><span>="item_number"</span><span> value</span><span>="可用于跟踪购买或捐赠的传递变量,在付款完成时传回给您"</span><span>/></span> <span><</span><span>input </span><span>type</span><span>="hidden"</span><span> name</span><span>="amount"</span><span> value</span><span>="物品的价格(购物车中所有物品的总价格"</span><span>/></span> <span><</span><span>input </span><span>type</span><span>="hidden"</span><span> name</span><span>="currency_code"</span><span> value</span><span>="币种"</span><span>/></span> <span></</span><span>form</span><span>></span>
二、IPN验证部分

即时付款通知(IPN)示意图如下:
1) 客户点击“付款”按钮向您的账户付款;
2) PayPal 接受到客户的付款后,向您的服务器指定的 URL 通过 POST 方式发送 IPN;
3) 在您的服务器收到 IPN 之后,您必须将收到的 POST 信息对原样返回给 PayPal 进行验证,PayPal 通过此方法帮您防范欺骗或“中间人”攻击;(对IPN信息的验证过程我们称之为通知确认)
4) PayPal 返回验证信息,通过验证为 VERIFIED,不通过则为 INVALD;
5) 根据验证信息处理付款明细。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
