【问题描述】：
总结：Stripe API：CurlClient.php 有一个 CURLOPT_HEADERFUNCTION，curl 在执行 curl_exec 命令时无法找到它。
Stripe API 版本 3.2.0（使用命名空间的较新版本）使用 PHP 版本 5.4.45 和 CURL 版本 7.36.0。我从 GitHub 下载了库，并使用库提供的 init.php 例程来绑定 Stripe 类。
我可以使用 Stripe.js 获取令牌，传递到我的服务器，进行身份验证并收取费用：
\Stripe\Charge::create(array(
"amount" => 400,
"currency" => "cad",
"source" => "tok_74MBD61UgMTtN7", // obtained with Stripe.js
"description" => "Charge for test@example.com"
), array(
"idempotency_key" => "yfwO6fUZh4qHctt6",
));
我收到一个错误：与 Stripe 通信时出现意外错误。如果此问题仍然存在，请通过 support@stripe.com 告知我们。 （我已经联系了 Stripe，但在 3 天内没有收到他们的消息。）
我的错误例程显示：无效的回调，没有给定文件的数组或字符串 (...)stripe-php-3.2.0/lib/HttpClient/CurlClient.php。调查显示，CurlClient.php 中的 curl_exec 会抛出错误，因为它找不到 $headerCallback。如果我注释掉这一行：
$opts[CURLOPT_HEADERFUNCTION] = $headerCallback;
然后一切正常，当然我没有将任何标头传递回调用函数。但是，我确实返回了 json，并且可以从 Stripe 控制面板看到成功的收费。
那么，关于为什么 Strip API 无法正常运行的任何想法？
在此处发布 CurlClient.php：

尝试将金额作为字符串传递。
