爬虫工具概览​

Google 按图搜索爬虫工具。通过 SE::Google::ByImage 爬虫工具，您可以获取图像链接库或准备好供进一步使用的图像。您可以直接使用在 Google 搜索栏中输入的原始查询格式。

A-Parser 的功能允许您保存 Google 爬虫工具的数据抓取设置以便日后使用（预设），设置数据抓取计划等等。您可以使用自动查询扩展、从文件中替换子查询、遍历数字字母组合和列表，以获取尽可能多的结果。

由于内置了强大的 Template Toolkit 模板引擎，您可以按所需的格式和结构保存结果，该引擎允许对结果应用额外的逻辑并以各种格式输出数据，包括 JSON, SQL 和 CSV。

爬虫工具应用场景​

A-Parser 允许使用任务链，在第一个任务完成后，将开始执行第二个任务，第一个任务中的链接将作为第二个任务的查询。
