webscraper簡介

Web Scraper 是一款網頁資料採集工具，只要是我們日常在網頁上可以瀏覽到的內容，它都可以幫助我們爬取下來。

Web Scraper最大的特色是免費和免程式設計，不懂程式設計的人也很容易操作，儘管在爬取網頁資料方面也有很多工具，但綜合對比來看還是web scraper更加方便快捷一些。

Web Scraper主要有以下幾個特點：

輕量級，只是瀏覽器外掛，無需在電腦中安裝
免費，並且沒有按下載資料條數收費的要求
免程式設計，好上手，一天學會無壓力
唯一缺點是免費版不能設定定時任務

webscraper下載

登入官方網站進行外掛安裝，外掛有兩種瀏覽器可供選擇：火狐或者谷歌的Chrome。我選擇的是火狐瀏覽器，如果選用Chrome瀏覽器，則需要科學上網。
（具體下載網址不方便貼上，可以私信獲取）
