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).textfor 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)
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:

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:
搞定!!!!
