您好，我尝试在 PayPal 中使用欧元创建付款，但出现错误。但是当我使用美元付款时它工作正常。

最佳答案
用这个替换你的代码，paypal 不推荐使用一些字段，比如
PAYMENTACTION 到 PAYMENTREQUEST_n_PAYMENTACTION
AMT TO PAYMENTREQUEST_n_AMT
CUSTOM 到 PAYMENTREQUEST_n_CUSTOM
$nvpstr = "&TOKEN=" . $token;
$nvpstr = $nvpstr . "&PAYMENTREQUEST_0_PAYMENTACTION=Sale";
$nvpstr = $nvpstr . "&PAYERID=" . $payerID;
$nvpstr = $nvpstr . "&PAYMENTREQUEST_0_AMT=" . $paymentAmount;
$nvpstr = $nvpstr . "&PAYMENTREQUEST_0_CUSTOM=" . $userId;
$nvpstr = $nvpstr . "&PAYMENTREQUEST_0_CURRENCYCODE=".$currency;
您在“DoExpressCheckoutPayment”API 调用中进行这些更改应该没问题。
