【API接口封装系列】程序员的福音，高效取电商商品详情页面数据

业务场景：作为全球最大的 B2C 电子商务平台之一，淘宝天猫平台提供了丰富的商品资源，吸引了大量的全球买家和卖家。为了方便开发者接入淘宝天猫平台，淘宝天猫平台提供了丰富的 API 接口，其中历史价格接口是非常重要的一部分。大家有探讨稳定采集淘宝（天猫）京东阿里拼多多等平台整站实时商品详情历史价格数据接口，通过该接口开发者可以更好地了解商品的情况，商品详情数据详细信息查询，数据参数包括：商品链接，商品列表主图、价格、标题，sku，库存，销量，店铺昵称，店铺等级，商品详情SKU属性，商品视频，商品优惠券，促销信息，详情属性描述，宝贝ID，区域ID,发货地，发货至，快递费用，物流费用等页面上有的数据完整解决方案帮助买家更准确地进行商品选购及商品分析。

这个引起了我对技术挑战的兴趣。目前，自己做了压测，QPS 高、出滑块概率极低，API 整体稳定，可满足商品分析，竞品分析，品牌监控，商品搬家，商品上传，商城建设，淘宝客，erp 选品，店铺同步，CID 店铺订单回传接口等业务场景的性能需求，下面介绍接口封装代码教程：

首先，大家要到官方主页去申请一个 appkey，这个是做什么用的呢？App Key 是应用的唯一标识，TOP 通过 App Key 来鉴别应用的身份。AppSecret 是 TOP 给应用分配的密钥，开发者需要妥善保存这个密钥，这个密钥用来保证应用来源的的可靠性，防止被伪造。就是说嘛，想要进门可要先有钥匙啊，所以，appkey 就是我们进入 openAPI 大门的钥匙。点击获取请求key和secret
