很少有Google Checkout问题

我打算在社交网站上整合Google Checkout支付系统。我们的想法是,会员可以购买真钱的“代币”(这是一种网站货币),然后他们就可以购买网站上一些额外内容的访问权。

我想要做的是创建一个Google Checkout按钮,将会员带到结账页面,用他的信用卡或借记卡付款。我想要的是Google Checkout通知我的服务器是否成功购买代币(如果信用卡/借记卡已收费),我可以更新本地数据库。

该网站采用PHP / MySQL编码。

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

我知道如何创建Google结帐按钮,我还在我的服务器上放置了responsehandlerdemo.php文件。这是Google Checkout应该发送回复的文件(当然我在Google商家帐户中设置了该文件的路径)。

现在在响应处理程序文件中有一个包含多个case语句的switch块。哪一个意味着付款成功,我可以将令牌添加到本地数据库中的成员帐户?

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

  break;

  $merchant_calc = new GoogleMerchantCalculations($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

我猜那个案子'充电'就是那个,我是对的吗?

第二个问题,我是否需要SSL证书才能收到Google Checkout的回复?根据这个,我做:groups.google.com/group/google-checkout-api-php/browse_thread/thread/10ce55177281c2b0

但我不会在官方文档中的任何地方看到它。

谢谢。

我在6个月前将其整合到我的网站中。它的体积非常小,但到目前为止效果很好。


你应该担心的第一件事是'充电'。这意味着信用卡已被批准用于交易,但在您采取行动之前,它实际上不会收取资金。要发送费用请求,只需取消注释CHARGEABLE下的两行即可。您可以更改设置,使其在“设置”&gt;中自动为卡充电'偏好',但您也可以取消评论2行并保持选项开放。

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

在某些时候,我确信您还应该检查该请求是否有足够的信息让您在充值之前将资金链接到某个帐户,但这可能只是我的偏执狂。


我使用的另一个州是“费用金额通知”。完全可能有一种方法可以使用'CHARGED',但我不认为'CHARGED'提供实际收费的金额。 ($ amount_charged = $ data [$ root] ['total-charge-amount'] ['VALUE'];)


对于SSL,如果您检查输入回调URL的位置,则说明以下内容: “指定Google的URL以通知您订单状态中的新订单和更改。您必须提供运行128位SSLv3或TLS的服务器的URL”


回答你的意见: 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( $items as $item ) { 
   if( !isset ( $item['merchant-item-id']['VALUE'] ) ) { 
     //error 
     return; 
   } 
   $request_item_id = $item['merchant-item-id']['VALUE']; 
   //save your item id with corresponding google order id for further processing
}

是的,“费用”是您在Google Checkout订单中首先需要查看的内容。当您点击“可充电”时,会弹出一个窗口,让您实际收取订单确保“符合保护条件”为真,然后才能实际收到订单。这可确保您的付款受到Google付款保证的保障。您实际上可以在Google Checkout的“买家信用验证”部分中看到它。
