使用PayPal PHP SDK在PayPal沙箱上执行支付时获得Http响应代码400

Question

PayPal\Exception\PayPalConnectionException
Got Http response code 400 when accessing https://api.sandbox.paypal.com/v1/payments/payment/PAYID-L7KLVNA5VA13973Y0247405F/execute.

我的灵感来自：https://github.com/evolutednewmedia/paypal-rest-api-example/blob/master/src/response.php

我也尝试过：https://paypal.github.io/paypal-php-sdk/sample/doc/payments/executepayment.html

下面是我返回URL的代码：

public function actionResponse($paymentId, $PayerID)
    {
        if( $paypalPayment = PaypalPayment::find()->where(['transaction_id' => $paymentId])->one() ) {
            $order = $paypalPayment->getOrder()->one();
        }else{
            die('Can not find PayPal reference in DB');
        }

        $apiContext = $this->getApiContext(self::OMT_PAYPAL_CLIENT_ID, self::OMT_PAYPAL_CLIENT_SECRET, self::OMT_PAYPAL_SANDBOX);

        $amount = new Amount();
        $amount->setCurrency($order->currency);
        $amount->setTotal($order->amount/100);

        $transaction = new Transaction();
        $transaction->setAmount($amount);


        $execution = new PaymentExecution();
        $execution->setPayerId($PayerID);
        $execution->addTransaction($transaction);

        //die($execution);

        $payment = Payment::get($paymentId, $apiContext);

        try {
            $payment->execute($execution, $apiContext);

            try {

                $paypalPayment = PaypalPayment::find()->where(['transaction_id' => $payment->getId()])->one();
                $paypalPayment->payment_amount =  $payment->transactions[0]->amount->total;
                $paypalPayment->payment_status =  $payment->getState();
                $paypalPayment->invoice_id =  $payment->transactions[0]->invoice_number;

                if ($paypalPayment->save() && $paypalPayment->payment_status === 'approved') {
                    // Payment successfully added, redirect to the payment complete page.
                    echo 'success';
                } else {
                    // Payment failed
                    echo 'Payment failed';

                }

            } catch (Exception $ex) {
                // Failed to retrieve payment from PayPal
                die('Failed to retrieve payment from PayPal');
                echo $ex->getCode();
                echo $ex->getData();
                die($ex);

            }

        } catch (Exception $ex) {
            // Failed to take payment
            die('Failed to take payment from PayPal');
            echo $ex->getCode();
            echo $ex->getData();
            die($ex);

        }
    }

不推荐使用V1/Payments PayPal-PHP-SDK。

使用v2 Checkout-PHP-SDK，在这里进行了说明：https://developer.paypal.com/docs/business/checkout/server-side-api-calls/

您需要两条路由，一条用于“创建订单”，另一条用于“捕获订单”。
