前言 在服饰供应链采集场景中，很多方案习惯用商品 ID 请求 VVIC 详情接口，但业务侧经常只有前端商品链接，需要先从 URL 提取唯一标识再拉取数据。本文不再单纯演示基础请求调用，重点实现链接自动解析 + 异常 URL 容错 + 多规格数据扁平化，解决链接格式多变、SKU 数组嵌套、图片地址加密等线上痛点，代码增加重试与字段过滤，适合批量爬虫、供应链数据同步场景。 前置准备 依赖：requests 库，用于 HTTP 请求 权限说明：接口调用需携带合法请求头，模拟客户端访问，高频请求建议增加延时，避免触发风控 输入：VVIC 商品详情页 URL，自动提取商品编号，无需手动截取 ID 完整代码示例 核心逻辑解读 URL 解析模块：正则表达式自动提取 goodsId，兼容带参数、末尾斜杠等多种不规则链接，省去人工截取。 会话复用：使用 Session 保持 cookie，减少握手开销，批量采集场景性能更优。 数据扁平化处理：原始返回 SKU 为嵌套数组，清洗后转为简易列表，方便直接入库。
