pyhton爬取爱豆(李易峰)微博评论

  今日目标:微博,以李易峰的微博为例:
https://weibo.com/liyifeng2007?is_all=1  然后进入评论页面,进入XHR查找真是地址:
https://weibo.com/aj/v6/comment/big?ajwvr=6&id=4353796790279702&from=singleWeiBo  很明显,是动态的,抓取也是按我以前写的那些方法来,就不一一说了,他这里最重要的还是那串数字,所以我们只要在第一个网址哪里把那串数字找出来就算成功一半了,这次需要用到re正则,嗯,这个我不擅长,不过没事,应该还是可以搞到的:

}


html = requests.get(target,headers=headers).text


for each in re.findall('(.*?)<\/div>', res)


for each in conmment:
      # 将 内容里的那些表情替换
      each = re.sub('<.*?>','',each)
      print(each)

  re 不太会用,大家将就着看,主要是能把数据搞到手,这个最重要,哈哈…


  把那些表情给去除了,有些只发表情没法字的就会只显示名字,这个是正常的,其余就是一毛一样了。
  数据拿到了,咱们就存储到本地吧,全部代码:

  只是测试,所以就只爬了十几页:


  爬下来后可以自己对比一下:
