篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了404 curl_error当我在CURLOPT_HTTPHEADER中添加PayPal-Mock-Response时相关的知识，希望对你有一定的参考价值。

以下代码适用于成功的paypal交易没有错误（没有paypal-mock-response）。

当我在qazxsw poi中添加qazxsw poi来测试不同的场景，因为paypal建议在"PayPal-Mock-Response:{"mock_application_codes": "MALFORMED_REQUEST"}" CURLOPT_HTTPHEADER返回https://developer.paypal.com/docs/api/request-headers/#test-api-error-handling-routines

问题必须是我在curl_error()添加The requested URL returned error: 404 Not Found的方式，但我还没弄明白。

paypal_button.php

"PayPal-Mock-Response:{"mock_application_codes": "MALFORMED_REQUEST"}"

process.php

CURLOPT_HTTPHEADER

没有PayPal-Mock-Response的事务中的print_r（$ result），如果它有帮助：

<?php
    define("BASE_URL", "http://my_website.com/paypal_test/");
    define("PayPal_CLIENT_ID", "my_paypal_client_id");
    define("PayPal_BASE_URL", "https://api.sandbox.paypal.com/v1/");
?>
<div id="paypal-button-container"></div>
<script src="https://www.paypalobjects.com/api/checkout.js"></script>
<script>
    paypal.Button.render(
    {
        env: 'sandbox',
        client: {
            sandbox:    '<?php echo PayPal_CLIENT_ID; ?>'
        },
        commit: true,
        style: {
            layout: 'horizontal',
            fundingicons: 'true'
        },
        // payment() is called when the button is clicked
        payment: function(data, actions) 
        {
            // Make a call to the REST api to create the payment
            return actions.payment.create({
                payment: {
                    transactions: [
                        {
                            amount: {
                                total: '200',
                                currency: 'EUR'
                            }
                        } ]
                },
                experience: {
                    input_fields: {
                        no_shipping: 1
                    }
                }
            });
        },
        // onAuthorize() is called when the buyer approves the payment
        onAuthorize: function(data, actions) 
        {
            // Make a call to the REST api to execute the payment
            return actions.payment.execute().then(function() 
            {
                console.log('Payment Complete!');
                window.location = "<?php echo BASE_URL ?>process.php?paymentID="+data.paymentID+"&payerID="+data.payerID+"&token="+data.paymentToken
            });
        }
    }, '#paypal-button-container');
</script>
答案

根据<?php define("BASE_URL", "http://my_website.com/paypal_test/"); define("PayPal_CLIENT_ID", "my_paypal_client_id"); define("PayPal_SECRET", "my_paypal_secret"); define("PayPal_BASE_URL", "https://api.sandbox.paypal.com/v1/"); try { function paypalCheck($paymentID, $payerID, $paymentToken) { // Request Access Token $ch = curl_init(); $clientId = PayPal_CLIENT_ID; $secret = PayPal_SECRET; curl_setopt($ch, CURLOPT_URL, PayPal_BASE_URL.'oauth2/token'); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_USERPWD, $clientId .
