我看了一下源代码,这个是因为打开的页面只能看到20个答案:
其实可以用这种方式打开:https://www.zhihu.com/question/40132462?sort=created&nr=1&page=1
先爬取有多少个答案,根据答案数量确定page数,然后爬每一页,这样就可以把所有的答案爬取下来,想改来着,但是不太明白get_all_answers函数中这段代码
for i in xrange((answers_num - 1) / 50 + 1):
if i == 0:
for j in xrange(min(answers_num, 50)):
if self.soup == None:
self.parser()
soup = BeautifulSoup(self.soup.encode("utf-8"))
............
的意义。。

知乎以前一次是加载50个答案的,现在改成20了,把代码里的50改成20就可以了

原来是这样,我脑袋里完全是另一段代码。。。。。。不好意思:sweat_smile:
