要获取电商平台的商品数据进行竞品分析，可以采用以下几种方法：
1. 通过爬虫技术获取：使用Python等编程语言编写爬虫程序，模拟用户在电商平台的操作，例如搜索、翻页、点击商品等，然后获取页面的HTML源码，提取其中的商品信息。但需要注意的是，这种方式涉及到网站的反爬虫机制和法律风险，需要谨慎使用。
2. 联系电商平台合作：如果具备相关资源和资质，可以联系电商平台官方寻求合作，获取他们提供的开放API接口来获得数据。
3. 使用第三方工具：市面上有些付费的数据采集工具，可以帮助我们快速获取电商平台的商品数据，如SimilarWeb、DataForSEO等。但需要注意的是，这些工具的数据可能不够精确，且价格较高。
无论使用哪种方法，一定要遵守相关法律法规，尊重电商平台的数据隐私权和商业权益。
下面是我之前用爬虫爬取淘宝商品数据的返回示例，希望可以给需要的朋友一点帮助。
