laravel paypal 使用 paypal/rest-api-sdk-php 集成错误

Question

在我单击 myweb 应用程序中的付款按钮时出现的错误下方。我看过类似问题的解决方案可能是什么，但似乎无法解决我的解决方案。 访问https://api.sandbox.paypal.com/v1/payments/payment时得到 Http 响应代码 400。 PayPal\Core\PayPalHttpConnection: ERROR: Got Http response code 400 when access https://api.sandbox.paypal.com/payment.com/v1/payments . {"name":"MALFORMED_REQUEST","message":"Incoming JSON request does not map to API request","information_link":"https://developer.paypal.com/webapps/developer/docs/api/#MALFORMED_REQUEST ","debug_id":"7abde5aa538aa"}

Answer 1

PayPal-PHP-SDK 和 v1/payments API 已弃用。

而是将 Checkout-PHP-SDK 用于 v2/checkout/orders API，记录在此： https://developer.ZA0A058BAAEEF16E88F6BD2EE36C03F6-server-api-api.com/docs/business/checkout-serverside-api-api.com/ -调用

您应该制作两条路线，一条用于“创建订单”，一条用于“捕获订单”。 这些路由应仅返回/输出 JSON 数据（无 HTML 或文本）

将这两条路线与以下批准流程配对： https://developer.paypal.com/demo/checkout/#/pattern/server
