旧商城把规格存在这个字段，要怎么把这个字段的数据存到多商户的商品规格表
帮忙写段代码把这个数据遍历后存到规格去
[{"Spec":"KFR-72LW/N8KS1-1","Price":"6399","Num":"322","PriceCooperate":"5405","PricePartner":"5319","PriceService":"5759","PriceSatur":"5299","MinBuy":"1","CommService":10,"CommPartner":6.88,"DiscPartner":16.877637130802,"DiscService":10.001562744179},{"Spec":"KFR-51LW/N8KS1-1","Price":"5399","Num":"154","PriceCooperate":"4784","PricePartner":"4690","PriceService":"4859","PriceSatur":"4599","MinBuy":"","CommService":10,"CommPartner":3.13,"DiscPartner":13.132061492869,"DiscService":10.001852194851}]
在哪个位置遍历，哪个方法可以存这个规格的字段？
