Answer 1

Paypal经常返回内部服务器错误。这在沙盒模式中很常见。最常见的是再试一次，然后get execute。

Answer 2

您包含了不应该包含的元素，并且遗漏了重要的元素。如果你正在设置PayPal支付，你需要取消并返回url:

{
    "redirect_urls":{
        "return_url":"http://<return URL here>",
        "cancel_url":"http://<cancel URL here>"
    },
    "transactions":[
        {
            "amount":{
                "currency":"USD",
                "total":"12.00"
            },
            "description":"This is the payment transaction description."
        }
    ],
    "intent":"sale",
    "payer":{
        "payment_method":"paypal"
    }
}

Answer 3

在我的情况下，我将Content-Type标头设置为application/json，并获得有意义的响应:

{"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":"688b8ab4b2895"}

代替:
