Paypal连接Timedout

Question

我试图通过composer设置paypal checkout，当我运行它时，它在我们的实时站点中运行它时给了我一个连接超时异常，但它在我的localhost中完美运行。我现在正在使用Laravel框架。 Exception message

以下是用于它的代码

$ payer = PayPal :: Payer（）;         $ payer-＆GT; setPaymentMethod（ '贝宝'）;

    $amount = PayPal:: Amount();
    $amount->setCurrency('EUR');
    $amount->setTotal(42); // This is the simple way,
    // you can alternatively describe everything in the order separately;
    // Reference the PayPal PHP REST SDK for details.

    $transaction = PayPal::Transaction();
    $transaction->setAmount($amount);
    $transaction->setDescription('What are you selling?');

    $redirectUrls = PayPal:: RedirectUrls();
    $redirectUrls->setReturnUrl(action('PaypalController@getDone'));
    $redirectUrls->setCancelUrl(action('PaypalController@getCancel'));

    $payment = PayPal::Payment();
    $payment->setIntent('sale');
    $payment->setPayer($payer);
    $payment->setRedirectUrls($redirectUrls);
    $payment->setTransactions(array($transaction));

    $response = $payment->create($this->_apiContext);
    $redirectUrl = $response->links[1]->href;

    return Redirect::to( $redirectUrl );
