今天爬取的是微博评论。

可以发现其特点是下一页评论的max_id在上一页中。

于是代码如下：

import requests
import json
import re
import time
headers = {
    'User-Agent': '',
    "Cookie": "",
    "Referer": "https://m.weibo.cn/detail/4991918748471161"
}
url="https://m.weibo.cn/comments/hotflow?id=4991918748471161&mid=4991918748471161&max_id_type=0"

def get_page(url):
    response = requests.get(url, headers=headers)
    maxid=response.json()['data']["max_id"]
    if response.status_code == 200:
        return response, maxid
    else:
        print("请求失败")

def parse_page(datas):
        for data in datas:
            item=re.compile(r'<[^>]+>',re.S).sub('',data["text"])
            print(item)
            print("----------")

def get_url(max_id):
    urls=[]
    for i in range(1,14):
        print("第"+str(i)+"页")
        url="https://m.weibo.cn/comments/hotflow?id=4991918748471161&mid=4991918748471161&max_id="+str(max_id)
        r=requests.get(url,headers=headers)
        max_id=r.json()['data']["max_id"]
        datas=r.json()['data']["data"]
        parse_page(datas)
        time.sleep(1)
        print("第"+str(i)+"爬取完毕")


if __name__ == '__main__':
    html,max_id = get_page(url)
    get_url(max_id)

运行效果：
