Question

大家好我不知道我是否做得对，但我无法理解google checkout是如何运作的。我有PHP代码将XML发送到谷歌结账一切都很好我在结账过程中达到税收价格运输是好的。

$_currency    = $params['currency'];
            $base_domain  = 'https://' . (($params['mode'] == 'transaction') ? 'checkout.google.com' : 'sandbox.google.com/checkout');
            $base_url     = $base_domain . '/cws/v2/Merchant/' . $params['merchantId'] . '/checkout';

            // Form XML array with cart items
            $_items = '';

            $google_products = $this->CI->go_cart->contents();

            foreach ($google_products as $k => $v) {
                $item_options = '';

                if (isset($v['options'])) {
                    foreach ($v['options'] as $name => $value) {
                        if (is_array($value)) {
                            foreach ($value as $item) {
                                $item_options .= $item;
                            }
                        } else {
                            $item_options .= $value;
                        }
                    }
                }


                $_items .= '<item>' . '<merchant-item-id>' . $v['id'] . '</merchant-item-id>' . '<item-name>' . strip_tags($v['name']) . ' ' . $item_options . '</item-name>' . '<item-description>' . substr(strip_tags($item_options), 0, 299) . '</item-description>' . "<unit-price currency='" . $_currency . "'>" . $v['price'] . '</unit-price>' . '<quantity>' . $v['quantity'] . '</quantity>' . '</item>';
            }

$xml_cart = "<?xml version='1.0' encoding='UTF-8'?>
    <checkout-shopping-cart xmlns='http://checkout.google.com/schema/2'>
      <shopping-cart>
        <merchant-private-data>
            <additional_data>
                <session_id>" . base64_encode($customer['bill_address']["email"] . date('h:i:s')) . "</session_id>
                <currency_code>" . $_currency . "</currency_code>
                <payment_id>" . base64_encode($customer['bill_address']["email"] . date('h:i:s')) . "</payment_id>
                " . $private_ship_data . "
            </additional_data>
        </merchant-private-data>
        <items>" . $_items . "</items>
      </shopping-cart>
      <checkout-flow-support>
        <merchant-checkout-flow-support>

          <request-buyer-phone-number>true</request-buyer-phone-number>
          <edit-cart-url>" . $edit_cart_url . "</edit-cart-url>
          <merchant-calculations>
            <merchant-calculations-url>" . $calculation_url . "</merchant-calculations-url>
          </merchant-calculations>
          <continue-shopping-url>" . $return_url . "</continue-shopping-url>
          " . $shippings . $taxes . "
        </merchant-checkout-flow-support>
      </checkout-flow-support>
    </checkout-shopping-cart>";

            $signature     = $this->fn_calc_hmac_sha1($xml_cart, $params['merchantKey']);
            $b64_cart      = base64_encode($xml_cart);
            $b64_signature = base64_encode($signature);


            echo '<form method="post" action="' . $base_url . '" name="BB_BuyButtonForm">
        <input type="hidden" name="cart" value="' . $b64_cart . '" />
        <input type="hidden" name="signature" value="' . $b64_signature . '" />
        <input alt="" src="' . $base_domain . '/buttons/checkout.gif?merchant_id=' . $params['merchantId'] . '&amp;w=160&amp;h=43&amp;style=' . 'white' . '&amp;variant=text&amp;loc=en_US" type="image"/>
        </form>';

            exit;
        }

点击提交付款后，我会重定向到包含成功消息的页面，并带有返回我网站的链接。我想知道如何检查付款是否成功。还有一个回调，我不知道应该做什么。请帮助我更好地理解

我已附上以下代码。

免责声明：我不是PHP开发者。

上面的代码称为Part 1. Checkout API documented here。它涵盖了如何将数据/购物车添加到Google 以用于结帐
Part II. Order Processing介绍了如何从Google （进入您的系统）获取数据。提供了一个教程here。在这里，您提供Callback API URL 侦听（等待）来自Google的HTTP POST并继续处理数据。
