php - PayPal 付款 - HTTP 响应代码 400

Question

我正在使用 PHP 开发 PayPal 支付。一切都很好，直到出现此错误:

访问时得到 Http 响应代码 400 https://api.sandbox.paypal.com/v1/payments/payment .

当我尝试为我的支付创建方法时抛出:$payment->create($api);

<?php

use PayPal\Api\Payer;
use PayPal\Api\Details;
use PayPal\Api\Amount;
use PayPal\Api\Transaction;
use PayPal\Api\Payment;
use PayPal\Api\RedirectUrls;
use PayPal\Exception\PayPalConnectionException;

require '../src/start.php';

$payer = new Payer();
$details = new Details();
$amount = new Amount();
$transaction = new Transaction();
$payment = new Payment();
$redirectUrls = new RedirectUrls();


// Payer
$payer->setPaymentMethod('paypal');



// Details
$details->setShipping('2.00')
->setTax('0.00')
->setSubtotal('20.00');

// Amount
$amount->setCurrency('GBP')
->setTotal('22.00')
->setDetails($details);

// Transaction
$transaction->setAmount($amount)
->setDescription('Membership');


// Payment
$payment->setIntent('sale')
->setPayer($payer)
->setTransactions($transaction);

// Redirect urls
$redirectUrls->setReturnUrl($myReturnUrl)
->setCancelUrl($myCancelUrl);

$payment->setRedirectUrls($redirectUrls);

try {

$payment->create($api);


} catch (Exception $e) {
    echo $e->getMessage();
}

为什么会这样？我该如何解决？我最终如何才能获得更详细的异常消息？

Answer 1

// Amount
$amount->setCurrency('GBP')
->setTotal('22.00')
->setDetails($details);

并确保您的 Paypal 企业帐户在我的情况下是您的主要货币，它可以很好地将值从“英镑”更改为“美国”

// Amount
$amount->setCurrency('USA')
->setTotal('22.00')
->setDetails($details);
