我正在工作的项目，我需要整合支付宝。我在Laravel 8中集成了PayPal。https://devnote.in/how-to-integrate-paypal-payment-gateway-with-laravel/
一切都很完美。但是我无法在我的沙箱活动选项卡中看到事务，所以我调试了代码，我在响应中发现的是
"CHECKOUTSTATUS" => "PaymentActionNotInitiated"
我认为这是错误的
$response = $provider->setExpressCheckout($data);
$response = $provider->setExpressCheckout($data, true);
这是我付款后的回复

有了这个EC API，当买家返回到您的网站时，您应该显示一个最终的订单审查页面，最终的批准操作将触发DoExpressCheckoutPaymentAPI调用(使用返回的url查询字符串中的EC令牌和PayerID)来创建一个PayPal交易。根据响应，您将显示一个感谢/成功消息-或关于无法处理付款的错误消息。在调用DoExpressCheckoutPayment之前，不会创建任何事务。
无论如何，您正在尝试的这种集成是与经典的EC API，这是几代人的旧(大约15年)。你不应该在任何新的集成中使用这个旧的API，你所遵循的指南是相当旧的，应该忽略。
相反，遵循当前的设置标准支付指南，并在您的服务器上创建2个路由，一个用于"创建订单"，一个用于"捕获订单"，记录在这里。两个路由都应该只返回JSON数据(没有HTML或文本)。在第二条路线中，当捕获API成功时，您应该将其结果支付详细信息存储在数据库中(特别是purchase_units[0].payments.captures[0].id，这是PayPal交易ID)，并在将返回JSON转发给前端调用者之前立即执行任何必要的业务逻辑(例如发送确认电子邮件或预订产品)。
将这2条路由与前端审批流程配对:https://developer.paypal.com/demo/checkout/#/pattern/server
