如何获取淘宝店铺的退款率呢？用ShopService4C.htm查询。

[jungwen]

据我了解，应该是使用：
http://rate.taobao.com/ShopService4C.htm?userNumId="UMFgGMGQ0vGQT"&shopID="103403516"&isB2C="false"&k=241161
或者使用：
http://rate.taobao.com/ShopService4C.htm?shopID="103403516"

但奇怪的是，将URL输入到浏览器，按回车，，，，，按一次回车，获取到的数据都不一样，太奇怪了，都不知道怎么搞的：

第一次：
{"avgRefund":{"indVal":"1.50","localVal":"5.52"},"isBShop":"block","punish":{"cPunishTimes":"0","indVal":"1.32","weibeiTimes":"0","punishCount":"0","localVal":"0","xujiaTimes":"0","eyiTimes":"0","miaoshuTimes":"0"},"ratRefund":{"merchReceiveTimes":"2","refundCount":"5","indVal":"5.03","localVal":"0.19","noReasonTimes":"0","merchQualityTimes":"0"},"complaints":{"afterSaleTimes":"","refundSumNum":"0","indVal":"0.00","violationTimes":"","localVal":"0.00","disputRefundNum":"0","taobaoSolveNum":"0","complaintsCount":"","refundSupportSellerNum":"0","reasons":[],"taobaoSolvePercent":"0.00"}}

2秒钟后再查询：
{"avgRefund":{"indVal":"2.28","localVal":"2.38"},"isBShop":"block","punish":{"cPunishTimes":"0","indVal":"0.85","weibeiTimes":"0","punishCount":"0","localVal":"0","xujiaTimes":"0","eyiTimes":"0","miaoshuTimes":"0"},"ratRefund":{"merchReceiveTimes":"1","refundCount":"6","indVal":"3.33","localVal":"3.90","noReasonTimes":"2","merchQualityTimes":"0"},"complaints":{"afterSaleTimes":"","refundSumNum":"0","indVal":"0.00","violationTimes":"","localVal":"0.00","disputRefundNum":"0","taobaoSolveNum":"0","complaintsCount":"","refundSupportSellerNum":"0","reasons":[],"taobaoSolvePercent":"0.00"}}

再次查询，又有变化，奇怪了，淘宝是不是出问题了，谁了解吗？？
{"avgRefund":{"indVal":"2.37","localVal":"3.34"},"isBShop":"block","punish":{"cPunishTimes":"0","indVal":"1.38","weibeiTimes":"0","punishCount":"0","localVal":"0","xujiaTimes":"0","eyiTimes":"0","miaoshuTimes":"0"},"ratRefund":{"merchReceiveTimes":"24","refundCount":"2829","indVal":"4.43","localVal":"16.28","noReasonTimes":"795","merchQualityTimes":"182"},"complaints":{"afterSaleTimes":"","refundSumNum":"0","indVal":"0.00","violationTimes":"","localVal":"0.00","disputRefundNum":"0","taobaoSolveNum":"0","complaintsCount":"","refundSupportSellerNum":"0","reasons":[],"taobaoSolvePercent":"0.00"}}
