Magento关闭Google Checkout模块受到的启发
今天在关闭Google Checkout模块的时候发现在CHECKOUT ONEPAGE遇到了问，就是明明已经关闭了，可结算页面还在加载GOOGLE CHECKOUT里的类。
由于我是在Mage_All里面直接代码级别关闭的，所以页面报错。

后来通过报错信息寻找发现是在结算页面需要加载允许的结算方式，正常配置文件应该走/Payment/etc/config.xml里的默认配置，可是Mage毕竟不是完美的，发现在Sales的模块配置文件竟有这样一段：
<payment> <googlecheckout> <active>1</active> <model>googlecheckout/payment</model> <title>Google Checkout</title> </googlecheckout> </payment>
这段配置本来应该在GoogleCheckout模块配置文件里的，我将其注释掉，OK了一切正常。
还有就是获取配置数据的getConfig方法，以往大家以为$path参数一定要写全，比如payment/googcheckout/active，其实你写开头的一部分也会有返回数据，你可以试试
Mage::getStoreConfig('payment');
你会发现，它返回的是一个多维数组。
你有用google checkout了，能相互交流下吗？
没用到，想把它关闭掉，在中国大家认的还是支付宝、财付通、拍拍等
