This is a static website demo. It does not use the JavaScript to load the data.
import crawlist as clif__name__=='__main__':# Initialize a pager to implement page flipping pager = cl.StaticRedirectPager(uri="https://www.douban.com/doulist/893264/?start=0&sort=seq&playable=0&sub_type=", uri_split="https://www.douban.com/doulist/893264/?start=%v&sort=seq&playable=0&sub_type=",
start=0, offset=25)# Initialize a selector to select the list element selector = cl.CssSelector(pattern=".doulist-item")# Initialize an analyzer to achieve linkage between pagers and selectors analyzer = cl.AnalyzerPrettify(pager, selector) res = [] limit =100# Iterating a certain number of results from the analyzerfor tr inanalyzer(limit):print(tr) res.append(tr)# If all the data has been collected, the length of the result will be less than the limitprint(len(res))
This is a dynamic website demo. It uses the JavaScript to load the data.So we need to load a selenium webdriver to drive the JavaScript.
