打开淘宝商品详情页后，抓包后会有类似这样的一个GET发包信息
http://count.tbcdn.cn/counter3?keys=DFX_200_1_9855818746,ICVT_7_9855818746,ICCP_1_9855818746,SCCP_2_64584149,ICE_3_feedcount-9855818746,ZAN_27_2_9855818746&inc=ICVT_7_9855818746&sign=6939f9d65fbdbd582cf7454340e684652e50&callback=TShop.mods.SKU.CounterCenter.saveCounts
其中的数字[9855818746]是商品的ID，想知道&sign=6939f9d65fbdbd582cf7454340e684652e50这个里面的参数是怎么算出来的。
