<?php

    $base = realpath($_SERVER["DOCUMENT_ROOT"]);
    require_once $base.'/gsys3/assets/php/paypal.api.php';

    use PayPal\Api\Payer;

    if(!isset($_SESSION['account'])){
        header('Location: ../../main.php');
    } elseif($_SESSION['account']['perms'] != 3){
        header('Location: ../../main.php');
    }

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

    $payer->setPaymentMethod('paypal');

    $shippingcost           = '1';
    $taxcost                = '7';
    $subtotalcost           = '100';
    $totalcost              = $shippingcost + $taxcost + $subtotalcost;

    $details->setShipping($shippingcost)
            ->setTax($taxcost)
            ->setSubtotal($subtotalcost);

    $amount->setCurrency('USD')
            ->setTotal($totalcost)
            ->setDetails($details);

    $transaction->setAmount($amount)
                ->setDescription('Enrollment');

    $payment->setIntent('sale')
            ->setTransactions([$transaction]);

    $redirectUrls->setReturnUrl('http://localhost:8080/gsys3/public/dashboard/parent/pay.php?approved=true')
                 ->setCancelUrl('http://localhost:8080/gsys3/public/dashboard/parent/pay.php?approved=false');

    $payment->setRedirectUrls($redirectUrls);

    try {

    }

    $apiContext->setConfig(
        array(

            'log.LogEnabled' => true,
            'log.FileName' => 'PayPal.log',
            'log.LogLevel' => 'DEBUG',
        )
    );

我已经检查了客户端和密钥，这些密钥是准确的

我建议您激活的日志以获取有关异常的更多信息。这些是我的开发设置

你查过了吗？@pyromank是的，我查过了，我想我放对了参数。如果它返回400，那么其中一个参数很可能是关闭的。我建议你回音（除非有安全隐患）。谢谢你，我会尽快尝试的

    $apiContext->setConfig(
        array(
            'mode' => 'sandbox',
            'log.LogEnabled' => true,
            'log.FileName' => 'PayPal.log',
            'log.LogLevel' => 'DEBUG',
        )
    );
