网络抓取是一种从网站或应用程序中提取数据的系统。你可以手工操作，复制和粘贴数天，也可以雇佣机器人来帮你完成。

We call these robots web scrapers. You can program them to scan, collect, organize, and analyze web data faster than a team of data scientists jacked on caffeine. 成本也更低。(以咖啡和美元计）

3 种网络搜刮工具。

Browser extension: These are simple web scraping solutions you can use on most browsers like Chrome and Safari. They are more suitable for small-scale web scraping projects because you can only scrape one page at a time. The benefit of using a browser scraping tool is that it tends to be free and easy to use. Installable software: These are downloadable software programs that can handle scraping multiple pages, ideal for most small-to-medium-sized projects. While these web scraping tools tend to have little cost, there is often a more significant learning curve. Cloud-based: These are commonly known as web scraping APIs. These exist on a cloud server owned and operated by a web scraping service. All you need to do is subscribe to one of their monthly plans and input the search parameters. They often come with web scraping proxies and require no coding. Web scraping APIs are more expensive but worth every penny for medium-to-large businesses who need to take data more seriously and are busy with more important tasks than messing around with technical know-how.
