php - Paypal 拒绝网站教程中示例代码的凭据

我一直在尝试通过 this interactive tutorial page 中的示例找出 PHP SDK .我稍微修改了代码以适应我自己的应用程序的目的并包括我自己的 clientId 和 clientSecret，但不足以构成重大违规。您将在下面的注释代码中看到我所做的更改。

我的问题是 payment->create() 方法不接受我的凭据。它抛出一个 400 代码异常，消息为“无效凭证”。我做错了什么？

代码:(输出如下)

        <?php
        //I wrote the PayPalAutoloader and stored it in the PayPal folder.
        //the autoloader uses the namespace data to parse the folder structure
        //and loads the corresponding object or throws an Exception if the file
        //is not found.
        require_once 'PayPal-PHP-SDK/PayPalAutoloader.php';

        //added my own INI file, where I can store API related values.
        $ini = \parse_ini_file('libsec.ini', true);
        $clientId = $ini['PayPal']['clientId'];
        $clientSecret = $ini['PayPal']['clientSecret'];

        //Step 1 of 5 from website
        $sdkConfig = [ "mode" => "sandbox"];
        $oauthCredential = new \PayPal\Auth\OAuthTokenCredential($clientId, $clientSecret, $sdkConfig);
        $apiContext = new \PayPal\Rest\ApiContext($oauthCredential);
        //end Step 1 of 5


        //observation, apiContext is never actually used in Step 1 and is redefined in Step 2

        //I found that to send the request I had to call getAccessToken (not mentioned in interactive tutorial)
        $accessToken = $oauthCredential->getAccessToken($sdkConfig);

        //peaking at the accessToken value
        var_dump( $accessToken );

        //Begin Step 2 of 5 from website
        //reuse sdkConfig from Step 1, it is unchanged
        $credentials = "Bearer {$accessToken}";
        $apiContext = new \PayPal\Rest\ApiContext($credentials, 'Request' . time() );
        $apiContext->setConfig($sdkConfig);

        $payer = new \PayPal\Api\Payer();
        $payer->setPaymentMethod("paypal");

        $amount = new \PayPal\Api\Amount();
        $amount->setCurrency("USD");
        $amount->setTotal("483.00");

        $transaction = new \PayPal\Api\Transaction();
        $transaction->setDescription("Annual Dues");
        $transaction->setAmount($amount);

        //removed as $baseURL is not actually used by any of the code that follows.
        //the results of the code are the same after commenting out the baseURL variable.
        //$baseUrl = getBaseUrl();
        $rootURL = $ini['General']['rootURL'];
        $successfulTransactionURL = $rootURL . $ini['PayPal']['success_bill_pay'];
        $cancelledTransactionURL = $rootURL . $ini['PayPal']['cancel_bill_pay'];
        $redirectUrls = new \PayPal\Api\RedirectUrls();
        $redirectUrls->setReturnUrl($successfulTransactionURL);
        $redirectUrls->setCancelUrl($cancelledTransactionURL);

        $payment = new \PayPal\Api\Payment();
        $payment->setIntent("sale");
        $payment->setPayer($payer);
        $payment->setRedirectUrls($redirectUrls);
        $payment->setTransactions($transaction);

        //a var_dump is added in the create method to look at the payment formatted as JSON prior to the
        //REST API call.
        $result = $payment->create($apiContext);

        //peaking at result
        var_dump( $result );

        ?>
    </body>
</html>

输出: enter image description here

上面的输出是来自同一次程序运行的 3 个独立的输出实例。第一个字符串是 $accessToken 的 var_dump() 以验证是否正在检索 token 。每次运行都会成功检索此 token ，并且值会更改。

第二个输出是在 Payment::create() 方法中形成的 $json 对象的 var_dump。此 json 对象被传递到 API 系统，以通过 POST 方法对“/v1/payments/payment”的硬编码地址进行 REST 调用。

输出的第三部分是异常，它已传播到屏幕并阻止了 Payment::create() 方法的完成。

最佳答案

经进一步调查，问题出在指定行的 RestHandler 中。代码如下:

    if ($credential == null || !($credential instanceof OAuthTokenCredential)) {
        throw new PayPalInvalidCredentialException("Invalid credentials passed");
    }

但是，当我转储 $credential 变量时，我有:

string 'Bearer A015kCDeXpDfAvtTj7dbRg7ldRk-OdKboQhPaY4EmYu-bRA' (length=54)

SDK 必须从编写教程时开始更新。不幸的是，从 PayPal 的 API 文档到这个交互式教程的链接仍然存在，但该链接已过时。

事实证明，当我在 OAuthTokenCredential 对象上调用“getAccessToken”时，它准备好在将来再次使用。我不需要存储结果并创建一个“Bearer”。 $ token 字符串。我再次使用相同的 OAuthTokenCredential，一切正常。

在寻找解决方案的过程中，我删除了我的代码并从网站上复制了代码，演示修复的工作代码如下:

        //storing the result is not needed, because the result automatically updates the same credential object.
