很少有Google Checkout问题

Question

我打算在社交网站上集成Google Checkout支付系统.这个想法是成员可以为真钱购买"代币"(这是一种网站货币)然后他们可以购买访问网站上的一些额外内容等.

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购买了令牌是否成功(如果信用卡/借记卡已被收费)所以我可以更新本地数据库.

该网站使用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 Checkout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？

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.

Answer 1

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">"偏好设置"中自动为卡充电,但您也可以取消注释2行并保持选项处于打开状态.

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-protection'] ['值']).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,以便您在收取资金之前将资金链接到某个帐户,但也许这只是我的偏执狂.

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,则会指出以下内容:"指定Google的URL以通知您新订单和订单状态的更改.您必须提供运行128-的服务器的URL位SSLv3或TLS"

回答你的评论:我在"new_order_notification"下执行此操作,不确定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
}
