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： ```python https://weibo.com/liyifeng2007?is_all=1 ``` 然后进入评论页面，进入XHR查找真是地址： ```python 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： ```python target = 'https://weibo.com/liyifeng2007?is_all=1' headers = { 'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.83 Safari/537.36', 'cookie': 'SUB=_2AkMowDDgf8NxqwJRmPoSyWnqao53ywzEieKenME7JRMxHRl-yT9kqnEjtRB6A0AeDzsLF_aeZGlWOMf4mEl-MBZZXqc_; SUBP=0033WrSXqPxfM72-Ws9jqgMF55529P9D9WWcpq860VQlJcIRRNP9pzqS; SINAGLOBAL=1033839351635.7524.1604108279474; login_sid_t=c071efc77911ceace152df2be5986e09; cross_origin_proto=SSL; WBStorage=8daec78e6a891122|undefined; _s_tentry=-; Apache=8275565331127.246.1604195643561; ULV=1604195643568:3:1:1:8275565331127.246.1604195643561:1604122447982; wb_view_log=1920*10801; UOR=,,editor.csdn.net' } 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…  对比一下：  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： ```python # -*- coding: utf-8 -*- """ Created on 2020-11-18 @author: 李运辰 """ #https://weibo.com/liyifeng2007?is_all=1 import requests import re,os url = 'https://s.weibo.com/?topnav=1&wvr=6' target = 'https://weibo.com/liyifeng2007?is_all=1' headers = { 'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.83 Safari/537.36', 'cookie': 'SUB=_2AkMowDDgf8NxqwJRmPoSyWnqao53ywzEieKenME7JRMxHRl-yT9kqnEjtRB6A0AeDzsLF_aeZGlWOMf4mEl-MBZZXqc_; SUBP=0033WrSXqPxfM72-Ws9jqgMF55529P9D9WWcpq860VQlJcIRRNP9pzqS; SINAGLOBAL=1033839351635.7524.1604108279474; login_sid_t=c071efc77911ceace152df2be5986e09; cross_origin_proto=SSL; WBStorage=8daec78e6a891122|undefined; _s_tentry=-; Apache=8275565331127.246.1604195643561; ULV=1604195643568:3:1:1:8275565331127.246.1604195643561:1604122447982; wb_view_log=1920*10801; UOR=,,editor.csdn.net' } html = requests.get(target,headers=headers).text for each in re.findall('(.*?)', res) # conmment = re.findall('(.*?)
