一、python

import requests
from bs4 import BeautifulSoup
import pymysql
import time


class Administrative(object):
    def __init__(self):
        self.db = pymysql.connect(host="127.0.0.1", port=3306,
                              database="county_db",
                              charset="utf8mb4", user="root",
                              password="admin")
        self.main()
        self.db.close()

    def main(self):
        base_url = http://www.stats.gov.cn/tjsj/tjbz/tjyqhdmhcxhfdm/2021/

        trs = self.get_response(base_url, provincetr)
        for tr in trs:  # 循环每一行
            datas = []
            for td in tr:  # 循环每个省
                province_name = td.a.get_text()
                province_url = base_url + td.a.get(href)
                print(province_name)
                trs = self.get_response(province_url, None)

                    city_name = tr.find_all(td)[1].string
                    city_url = base_url + tr.find_all(td)[1].a.get(href)
                    trs = self.get_response(city_url, None)
                    for tr in trs[1:]:  # 循环每个区
                        county_code = tr.find_all(td)[0].string
                        county_name = tr.find_all(td)[1].string
                        data = [province_name, city_code, city_name, county_code, county_name]
                        print(data)
                        datas.append(data)
                    time.sleep(1)
            sql = "insert into china (province_name,city_code,city_name,county_code,county_name) values (%s,%s,%s,%s,%s)"
            self.connect_mysql(sql, datas)

    def get_response(self, url, attr):
        response = requests.get(url)
        response.encoding = utf-8  # 编码转换
        soup = BeautifulSoup(response.text, lxml)
        table = soup.find_all(tbody)[1].tbody.tbody.table
        if attr:
            trs = table.find_all(tr, attrs={
          
   class: attr})
        else:
            trs = table.find_all(tr)
        return trs

    def connect_mysql(self, sql, data):
        cursor = self.db.cursor()
        try:
            result = None
            if data:
                if isinstance(data[0], list):
                    cursor.executemany(sql, data)
                else:
                    cursor.execute(sql, data)
            else:
                cursor.execute(sql)
                result = cursor.fetchall()
        except Exception as e:
            print(e)
            self.db.rollback();
        finally:
            cursor.close()
            self.db.commit();  # 提交操作
            return result


if __name__ == __main__:
    Administrative()

二、数据表SQL

CREATE TABLE `china` (
  `province_name` varchar(200) NOT NULL,
  `city_code` varchar(32) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL,
  `city_name` varchar(200) NOT NULL,
  `county_code` varchar(32) NOT NULL,
  `county_name` varchar(32) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL,
  PRIMARY KEY (`city_code`,`county_code`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

总结

亲测，可用，修改base_url，可以获取每年最新数据！
