如何使用第三方API采集电商数据呢？

电商商家最常唠叨的就是店铺运营难做。每日多平台店铺数据统计汇总繁琐耗时，人工效率偏低，且工作内容有限。

特别是眼下“618，双十一，双十二，年底大促”将至，如何提高运营的效率和质量、保证产品及服务的良性运作，是电商企业急需解决的难题。

01

数据，电商运营重中之重

数据（以及数据分析）对于电商而言至关重要。透过海量数据，商家可以了解客户行为和喜好，也可洞察同行对手的方向与动态，所谓知己知彼。

随着市场规模的普遍增大，业务规模的快速增长，电商业务流程开始变得纷繁复杂，其所涉及的交易数据量也将持续攀升。

为了能够在激烈的市场竞争中脱颖而出，很多电商公司会设立专门的岗位与人员，及时了解广告投放、产品价格和销量数据，根据竞品的产品和营销策略进行调整。

数据部门的运营人员访问电商平台页面，人工统计商品标题、商品价格、销量等信息、并复制粘贴到表格中，大量重复操作消耗了六七成的工作时间，且数据易遗漏、难监控。

数据整理效率会直接影响电商运营的报表分析速度，所以部分商家选择爬虫工具作为数据收集的主要工具，可以一次性抓取大量数据。

什么是爬虫？

爬虫，一般也称作“网络蜘蛛”（Spider），以编程的方式实现（使用Python开发脚本），通过发送http请求获取cookies或者直接注入网页等方式自动获取互联网上的数据。

由于使用Python语言写脚本直接操作HTML，爬虫非常灵活和精细，抓取网页数据的速度非常之快，抓取量巨大（甚至可达到几千万上亿的数据量）。

在应用时，爬虫采用接口或暴力破解的方式解析网页内容以获取资料，采集效率高，会对后台造成巨大负担，因此也会被反爬虫机制识别、禁止。爬虫API免费测试入口
