我正在测试使用 PHP 动态创建的基本 PayPal 按钮表单,并在页面加载时短暂延迟后使用 JS 提交到沙箱。大约一半的时间它工作正常,大约一半的时间 PayPal 以 500 错误响应。当我遇到错误时,我可以返回浏览器并让它重新提交完全相同的表单,在这一点上,它有时会再次工作,有时会出现错误。

任何想法将不胜感激。这可能是某种 cookie 问题吗?我已经向 PayPal 提交了一张票——还没有回复。谢谢!

编辑:这是相关代码。这是一个 Drupal 8 站点,它位于一个使用 Form API 的自定义模块中,用于多步骤表单。 buildForm() 被调用(然后是 validateForm()),然后是 submitForm()。本例中的流程在构建“步骤”3 之后开始。客户点击“支付”,submitForm() 被调用。

public function buildForm(array $form, FormStateInterface $form_state) {
...
//'step' 3
...
//'step' 4 is just to redirect to PayPal
elseif ($form_state->get('step') == 4) {
//prints in main form content area
$form['redirecting'] = array(
'#type' => 'html_tag',
'#tag' => 'div',
'#value' => $this->t('Redirecting to PayPal...'),
);
}
...
}

public function submitForm(array &$form, FormStateInterface $form_state) {
...
//called after 'step' 3
//gets id of record just inserted into database
$paypal_invoice = $query->execute()->fetchField();
$paypal_item_name = '[name of item]';
$paypal_amount = $form_state->getValue('amount');
$token = bin2hex(openssl_random_pseudo_bytes(16));

$paypal_html =
'<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post" target="_top" id="paypal_form">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="______________">
<input type="hidden" name="lc" value="US">
<input type="hidden" name="invoice" value="' . $paypal_invoice . '">
<input type="hidden" name="item_name" value="' . $paypal_item_name . '">
<input type="hidden" name="amount" value="' . $paypal_amount . '">
<input type="hidden" name="button_subtype" value="services">
<input type="hidden" name="no_note" value="1">
<input type="hidden" name="no_shipping" value="1">
<input type="hidden" name="rm" value="1">
<input type="hidden" name="return" value="http://__________________">
<input type="hidden" name="cancel_return" value="http://______________?cancel=1&token=' . $token . '">
<input type="hidden" name="currency_code" value="USD">
</form>
<script type="text/javascript">
window.onload = setTimeout(function() {
document.getElementById("paypal_form").submit();
}, 4000);
</script>';

//make sure html tags are evaluated
$rendered_message = \Drupal\Core\Render\Markup::create($paypal_html);
//string will be added to message area of form when 'step' 4 is loaded with buildForm()
drupal_set_message($rendered_message);

$form_state->set(['step'], 4);
...
}

最佳答案

回答我自己的问题以防对其他人有帮助:这是一个 PayPal 沙盒问题。

我在 PayPal 网站上生成了一个等效的按钮表单,在我的代码之外多次将其提交到沙箱,并遇到了类似的间歇性 500 错误。

然后我将代码中的引用切换到实时 PayPal 信息,运行了很多次(没有完成交易),没有出现任何错误。

因此,沙盒配置与实时配置有所不同,导致了这种情况(可能是内存问题?)。这一定不是一个独特的情况,因此令人沮丧的是 PayPal 没有记录沙箱的限制。但很高兴继续前进似乎没问题。

编辑:这是 PayPal 的确认回复。

We are aware of some issues with our PayPal Sandbox that intermittently causes a valid request to fail with a 500 Internal Server Error. Our developers are working on this issue and I will update you when the issue has been fully resolved.

Please note that this issue is only affecting the sandbox environment. No impact has been noted on the production environment.

进一步编辑:从 PayPal 更新。

Thank you for your patience as we tracked down the source of the instability on our Sandbox environment.

The PayPal engineers have resolved the issue that was resulting in the frequent Internal Server Errors. However, they have indicated that all requests should be going to the https://www.sandbox.paypal.com/ domain. If your integration is sending to https://sandbox.paypal.com (no www), then you may still experience some latency. Please update your integration, if this is the case for you, to include the www.
