crawler vs scraper

问题 Can somebody distinguish between a crawler and scraper in terms of scope and functionality. 回答1: A crawler gets web pages -- i.e., given a starting address (or set of starting addresses) and some conditions (e.g., how many links deep to go, types of files to ignore) it downloads whatever is linked to from the starting point(s).

How can I scrape website content in PHP from a website that requires a cookie login?

梦想的初衷 提交于 2019-11-26 20:27:15

Can anyone give me an example of how to accept cookies in Snoopy or Goutte? Thanks in advance! Object-Oriented answer We implement as much as possible of the previous answer in one class called Browser
