Shop::eBay - eBay 搜索结果爬虫工具
爬虫工具概览
使用 eBay 商品爬虫工具，您可以从商品详情页获取数据、采集商品链接库、监控商品价格动态、卖家数量变化、采集评分等级和评论数量，以及采集商品图片。
A-Parser 的功能允许您保存数据抓取设置以便后续使用（预设）、设置数据抓取计划等。您可以使用自动查询扩展、从文件替换子查询、遍历数字字母组合和列表，以获取尽可能多的结果。
采集的数据
- 商品名称
- 商品链接
- 商品图片
- 价格和原价
- 货币
- 评分和评论数
- 卖家数量
- 附加信息
应用场景
- 采集商品链接
- 评估商品受欢迎程度
- 监控价格动态和商品热度
查询
在查询中需要指定商品名称，就像直接在 eBay 搜索框中输入一样，例如：
mi band 6
iPhone 11
kingston CanvasGo+
AMD Ryzen R3 2200U
查询占位符
您可以使用 内置宏 来扩展查询，例如我们想要获取一个非常庞大的各品牌商品库：
philips
sony
xiaomi
samsung
在查询格式中指定从 a 到 zzzz 的字符遍历，此方法可以最大程度地轮换搜索结果并获取大量新的唯一结果：
$query {az:a:zzzz}
该宏将为每个原始搜索查询创建 475254 个额外查询，总计将产生 4 x 475254 = 1901016 个搜索查询，这个数字虽然惊人，但对于 A-Parser 来说完全不是问题。在每分钟 2000 个查询的速度下，此类任务仅需 16 小时即可处理完毕。
结果输出选项
得益于内置的 Template Toolkit 模板引擎，A-Parser 支持灵活的结果格式化，使其能够以任意形式输出结果，包括 CSV 或 JSON 等结构化格式。
