我们都知道淘宝平台推出了拍立淘功能，如果大家遇到了自己喜欢的商品，就可以拍一张照片，在淘宝用拍立淘搜索就能够出现相似的同款，这样就不用再去找别人要链接了。淘宝拍立淘主要是通过图片识别来找相似主图的宝贝，那么第三方软件如何实现批量按图片搜索淘宝商品，批量获取商品详情数据呢？
前段时间我试着利用网络爬虫技术，将拍立淘功能封装成一个API接口，调用此接口，即可轻松实现图片搜索商品功能。该API请求参数为图片地址（支持淘宝或天猫图片地址，外部地址先调用上传图片(upload_img)接口，返回图片地址）。
接口名称：item_search_img 图片搜索商品（拍立淘）
upload_img-上传图片到淘宝
-- 请求示例 url 默认请求参数已经URL编码处理 curl -i "https://api-服务器.cn/taobao/item_search_img/?key=<您自己的apiKey>&secret=<您自己的apiSecret>&imgid=http://g-search3.alicdn.com/img/bao/uploaded/i4/O1CN01IDpcD81zHbpHs1YgT_!!2200811456689.jpg&cat="
