我试图将PayPal SDK集成到我的网站中，但遇到了一个问题，我无法在文档中或通过Stackoverflow找到解决方案。

我使用标准设置：

start.php：

    <?php

    //require 'vendor/autoload.php';
    require __DIR__ . '/../vendor/autoload.php';

    use PayPal\Rest\ApiContext;
    use PayPal\Auth\OAuthTokenCredential;

    define('BASE_URL', 'http://localhost:80/paypaltut/');

    if(!defined("PP_CONFIG_PATH")){
            define('PP_CONFIG_PATH', '../vendor/paypal/rest-api-sdk-php/tests/');
            }
    $clientid = 'ARe54bHOzRcn13nRglDpIst46bWOp6pyBRYlP4nulwwTL2ivIuKlIJrUp5LdgZfuC0qPbqIuGdVFsmeK';
    $clientsecret = 'EJarieZ8B_6WEZ__gZl0uS-Dmc-ypa1RH1joF1u4_XlJje2IINBRCsARhNyZk-dJG7kBJS8ceQF5GNVr';

    $apiContext = new ApiContext(new OAuthTokenCredential($clientid, $clientsecret));

当我尝试使用我的应用的paypal沙盒版本处理付款时，我收到错误：

 exception 'PayPal\Exception\PayPalInvalidCredentialException' with message 'Credential not found for default user.

我已经完成了通过paypal开发人员的信息中心创建应用程序的过程，我尝试添加新的ApiContext到付费（返回网址）文件并仍然得到相同的错误。有谁知道如何解决这个问题？

哦，我正在使用v1.5.0 sdk和php 5.6.1

答案 0 :(得分：9)

找到根本原因。

您忘记传递$ apiContext对象以执行try { $result = $payment->execute($execute); } catch(Exception $e) { die($e); } 代码中的调用。 

try {
    $result = $payment->execute($execute, $apiContext);
}
catch(Exception $e){
    die($e);
}

将其更改为此，它应该有效：
