pyhton爬取爱豆(李易峰)微博评论(附源码)_爬数据

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:

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('<a name=(.*?)date=',html):
    real_id = each.split(" ")[0]
    filename = each.split("\\")[-2].replace('"',"").replace(":",".")
    print(real_id,filename)




输出如下:

第一个就是我们需要的ID,后面则是发微博的时间,我们用它来做存储评论数据的文件名称。

然后我们把ID传入第二个网址:

comment_url = f'https://weibo.com/aj/v6/comment/big?ajwvr=6&id={real_id}&from=singleWeiBo'


当然这个是抓取热度的,如你要抓取最新回复的,需要下面这个:

comment_url = f'https://weibo.com/aj/v6/comment/big?ajwvr=6&id={read_id}&page=1'


拿到这个就简单了,JSON 数据,直接进json网站解析就行,然后找到我们需要的数据,这里就直接上代码了:

comment_url = f'https://weibo.com/aj/v6/comment/big?ajwvr=6&id={real_id}&page=1'
res = requests.get(comment_url,headers=headers).json()["data"]["html"]


# 提取评论人和评论内容
conmment = re.findall('ucardconf="type=1">(.*?)</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:
