在codeigniter中条带支付网关集成

我使用stripe.js在codeigniter中使用Stripe支付网关 . 在条带支付过程中首先进行客户端验证，然后通过条带php 2.1.1库进行服务器端验证 . 客户端验证工作准备就绪，但服务器端验证会出错 . 我把条带php 2.1.1文件夹放在codeigniter库文件夹中 .

我推荐此链接http://code.tutsplus.com/tutorials/how-to-accept-payments-with-stripe--pre-80957

码：

<?php
$success = "";
$error = "";

require_once(APPPATH.'libraries/stripe/lib/Stripe.php');

if ($_POST) {
  Stripe::setApiKey("dm_wsdst_yJQB5mrfjpfQX2uMQHf3CbD");
  $error = '';
  $success = '';
  try {
    if (!isset($_POST['stripeToken']))
      throw new Exception("The Stripe Token was not generated correctly");
    Stripe_Charge::create(array("amount" => 11,
                                "currency" => "usd",
                                "card" => $_POST['stripeToken']));
    $success = 'Your payment was successful.';
  }
  catch (Exception $e) {
    $error = $e->getMessage();
  }
}

echo "sucess". isset($success) ? $success : "";
echo "error".isset($error) && $success ? $error : "";

?>

当我运行此文件然后运行准备，当我点击付款按钮然后检查卡数据和到期月份和年份，如果它是好的然后返回stripeToken然后再次重新提交表单然后它将返回错误，即

致命错误：第12行的D：\ xampp \ htdocs \ moviesaints \ application \ views \ user \ payment_precess.php中找不到“Stripe”类
