【问题描述】：

在我单击 myweb 应用程序中的付款按钮时出现的错误下方。我查看过类似问题的解决方案可能是什么，但似乎没有解决我的解决方案。 访问https://api.sandbox.paypal.com/v1/payments/payment 时得到 Http 响应代码 400。 PayPal\Core\PayPalHttpConnection：错误：访问https://api.sandbox.paypal.com/v1/payments/payment 时得到 Http 响应代码 400。 "name":"MALFORMED_REQUEST","message":"传入的 JSON 请求未映射到 API 请求"​​,"information_link":"https://developer.paypal.com/webapps/developer/docs/api/#MALFORMED_REQUEST ","debug_id":"7abde5aa538aa"

【参考方案1】：

PayPal-PHP-SDK 和 v1/payments API 已弃用。

改为使用 Checkout-PHP-SDK 作为 v2/checkout/orders API，此处记录：https://developer.paypal.com/docs/business/checkout/server-side-api-calls/#server-side-api-calls

您应该创建两条路线，一条用于“创建订单”，一条用于“捕获订单”。这些路由应该只返回/输出 JSON 数据（没有 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
