我刚刚开始熟悉Google Checkout API，但是有些事情我有一个问题。在Google Checkout文档中，提交实际购物车的唯一方法是通过echo调用创建的按钮，例如echo $cart->CheckoutButtonCode("LARGE");，但这不是我需要的。我想从我的PHP脚本手动提交我的购物车。
然而，与PayPal API不同的是，Google Checkout脚本中似乎没有提交类型函数。经过进一步的研究，我注意到HTML的例子将他们的字段发布到https://sandbox.google.com/checkout/api/checkout/v2/checkout/Merchant/MERCHANT_ID_HERE。
如何在PHP中做到这一点?我正在使用他们的官方API。以下是我目前所做的:
$merchant_id = $google_merchant_ID;
$merchant_key = $google_merchant_key;
if ($enable_Google_Sandbox == 1)
{
$server_type = "sandbox";
}
$currency = $currency_code;
$cart = new GoogleCart($merchant_id, $merchant_key, $server_type,
$currency);
$shop_cart = $_SESSION['cart'];
foreach ($shop_cart as $value)
{
$k_product = $value['Product'];
$k_quantity = $value['Quantity'];
$k_price = $value['Price'];
$k_orderID = $_SESSION['order_id'];
if (isset($_SESSION['Discount']))
{
$k_discount = $_SESSION['Discount'];
$k_price = $k_price - $k_discount;
}
$cart_item = new GoogleItem($k_product,
"Some Product",
$k_quantity,
$k_price);
$cart_item->SetMerchantItemId(generateProductID());
$cart->AddItem($cart_item);
}
// Specify <edit-cart-url>
$cart->SetEditCartUrl("http://192.168.100.100:8888/order.php?action=showCart");
// Specify "Return to xyz" link
$cart->SetContinueShoppingUrl("http://192.168.100.100:8888/store.php");
// Request buyer's phone number
$cart->SetRequestBuyerPhone(false);
没有$cart->submitCart();类型函数，我该怎么办?
list($status, $error) = $cart->CheckoutServer2Server();
那应该能解决你的问题。当您使用PHP api时，我可以推荐PHP演示。本例(DigitalUsecase())演示了CheckoutServer2Server。(digitalCart.php)
CheckoutServer2Server文档:
/**
* Submit a server-to-server request.
* Creates a GoogleRequest object (defined in googlerequest.php) and sends
* it to the Google Checkout server.
*
* more info:
* {@link http://code.google.com/apis/checkout/developer/index.html#alternate_technique}
*
* @return array with the returned http status code (200 if OK) in index 0
* and the redirect url returned by the server in index 1
