[python]爬取手机号码前缀和地区信息

概述

使用python爬取手机号码前缀7位、区号和地区。

小网站不容易，对爬虫也挺友好，就不放链接了。

代码

import requests
from lxml import etree
from fake_useragent import UserAgent
import time

def parse_page(url,header,cookie):
    """ 解析url，并写到文件中 """
    resp = requests.get(url,headers=header,cookies=cookie)
    html = etree.HTML(resp.text)
    filename = "phonenum.txt"

    # 爬取手机前缀
    phone_number_1 = html.xpath("//tr[@class='even']/td[1]/a/text()")
    # 爬取所在地区
    phone_number_1_city = html.xpath("//tr[@class='even']/td[2]/text()")
    # 爬取地区区号
    phone_number_1_citynum = html.xpath("//tr[@class='even']/td[4]/text()")

    phone_number_2 = html.xpath("//tr[@class='odd']/td[1]/a/text()")
    phone_number_2_city = html.xpath("//tr[@class='odd']/td[2]/text()")
    phone_number_2_citynum = html.xpath("//tr[@class='odd']/td[4]/text()")

    # 使用zip()组合爬取结果，并追加到文件中
    for i,j,k in zip(phone_number_1,phone_number_1_citynum,phone_number_1_city):
        with open(filename,"a",encoding="utf-8") as f_obj:
            f_obj.write(f"{i},{j},{k}\n")
    for x,y,z in zip(phone_number_2,phone_number_2_citynum,phone_number_2_city):
        with open(filename,"a",encoding="utf-8") as f_obj:
            f_obj.write(f"{x},{y},{z}\n")

def cookie_to_dict(cookie_src):
    cookie_dict = {}
    for i in cookie_src.split('; '):
        cookie_dict[i.split('=')[0]] = i.split('=')[1]
    return cookie_dict

def main():
    """ 执行主程序 """
    ua = UserAgent()
    # 地址很简单，直接range
    for page in range(1,1234):
        # 网站地址
        phone_url = "...........%d"%page
        phone_headers = {"User-Agent": ua.random}
        # 填写自己的cookie
        cookie_src = ""
        cookie = cookie_to_dict(cookie_src)
        parse_page(phone_url,phone_headers,cookie)
        print(f"page: {page}")
        # 暂停2秒，防止目标网站宕机
        time.sleep(2)

if __name__ == '__main__':
    main()

结果

爬取了463600条数据，部分数据如下：
