我计划在社交网站上集成 Google Checkout 支付系统。这个想法是会员可以用真钱购买“代币”(这是一种网站货币),然后他们可以购买对网站上一些额外内容的访问等。

我想做的是创建一个 Google Checkout 按钮,将会员带到结帐页面,他用信用卡或借记卡付款。我想要的是 Google Checkout 通知我的服务器令牌购买是否成功(如果信用卡/借记卡已收费),以便我可以更新本地数据库。

该网站使用 PHP/MySQL 编码。

我已经从这里下载了示例 PHP 代码:code.google.com/p/google-checkout-php-sample-code/wiki/Documentation

我知道如何创建一个 Google 结帐按钮,并且我还在我的服务器上放置了 responsehandlerdemo.php 文件。这是 Google Checkout 应该发送响应的文件(当然我在 Google 商家帐户中设置了文件的路径)。

现在在响应处理程序文件中有一个带有多个 case 语句的 switch 块。哪一项表示支付成功,我可以在本地数据库的会员账户中添加代币?

  switch ($root) {
case "request-received": {
  break;
}
case "error": {
  break;
}
case "diagnosis": {
  break;

case "checkout-redirect": {
  break;
}
case "merchant-calculation-callback": {
  // Create the results and send it
  $merchant_calc = new GoogleMerchantCalculations($currency);

  // Loop through the list of address ids from the callback
  $addresses = get_arr_result($data[$root]['calculate']['addresses']['anonymous-address']);
  foreach($addresses as $curr_address) {
    $curr_id = $curr_address['id'];
    $country = $curr_address['country-code']['VALUE'];
    $city = $curr_address['city']['VALUE'];
    $region = $curr_address['region']['VALUE'];
    $postal_code = $curr_address['postal-code']['VALUE'];

    // Loop through each shipping method if merchant-calculated shipping
    // support is to be provided
    if(isset($data[$root]['calculate']['shipping'])) {
      $shipping = get_arr_result($data[$root]['calculate']['shipping']['method']);
      foreach($shipping as $curr_ship) {
        $name = $curr_ship['name'];
        //Compute the price for this shipping method and address id
        $price = 12; // Modify this to get the actual price
        $shippable = "true"; // Modify this as required

          //Compute tax for this address id and shipping type
          $amount = 15; // Modify this to the actual tax value
          $merchant_result->SetTaxDetails($amount);
        }

        if(isset($data[$root]['calculate']['merchant-code-strings']
            ['merchant-code-string'])) {
          $codes = get_arr_result($data[$root]['calculate']['merchant-code-strings']
              ['merchant-code-string']);
          foreach($codes as $curr_code) {

            $coupons = new GoogleCoupons("true", $curr_code['code'], 5, "test2");
            $merchant_result->AddCoupons($coupons);

case "risk-information-notification": {
  $Gresponse->SendAck();
  break;
}
default:
  $Gresponse->SendBadRequestStatus("Invalid or not supported Message");
  break;

}

我猜那个案例是“CHARGED”,对吗?

第二个问题,我是否需要 SSL 证书才能接收来自 Google Checkout 的响应?根据这个我做:groups.google.com/group/google-checkout-api-php/browse_thread/thread/10ce55177281c2b0

但我在官方文档中的任何地方都没有看到它。

谢谢你。

6 个多月前,我将其整合到我的网站中。它的音量非常低,但到目前为止效果很好。


您应该担心的第一件事是“CHARGEABLE”。这意味着信用卡已被批准用于交易,但在您采取行动之前它不会实际收取资金。为了发送充电请求,只需取消注释 CHARGEABLE 下的两行。您可以更改设置以使其在“设置”>“首选项”中自动从卡中收费,但您也可以取消注释这两行并保持选项打开。

请注意,您可能希望等待“风险信息通知”并确定风险检查是否在批准收费之前通过 ($data[$root]['risk-information']['eligible-for-protection'] ['价值'])。虽然,您似乎在谈论数字商品,但退款的可能性对您来说可能并不重要。

在某些时候,我相信您还应该检查请求是否有足够的信息让您在收费之前将资金链接到某个帐户,但这也许只是我的偏执。


我使用的另一种状态是'charge-amount-notification'。完全有可能使用“收费”的方法,但我不认为“收费”提供了实际收费的金额。($amount_charged = $data[$root]['total-charge-amount']['VALUE'];)


至于 SSL,如果您检查输入回调 URL 的位置,它会说明以下内容:“为 Google 指定一个 URL,以通知您新订单和订单状态的变化。您必须提供运行 128 的服务器的 URL-位 SSLv3 或 TLS"


回答您的评论:我在“new_order_notification”下执行此操作,不确定您是否可以在其他地方执行此操作。

$items = get_arr_result($data[$root]['shopping-cart']['items']['item'] );
foreach( $item 作为 $item ) {
   if( !isset ( $item['merchant-item-id']['VALUE'] ) ) {
     //错误
     返回;
   }
   $request_item_id = $item['merchant-item-id']['VALUE'];
   //保存您的商品ID和相应的谷歌订单ID以供进一步处理
}

是的,“收费”是您在 Google Checkout 订单中首先需要查看的内容。当您点击“Chargeable”时,会弹出一个窗口让您实际对订单进行收费,在实际对订单收费之前,请确保“Eligible for Protection”为真。这可确保您的付款受到 Google 付款保证的保护。您实际上可以在 Google Checkout 的“买家信用验证”部分中看到它。
