微信公众号文章的爬取（搜狗微信搜索）

1.模拟浏览器登陆，获取cookies

2.request.get()带上cookies访问

3.反反爬虫（待定，目前是代理ip+休眠，搜狗模式：封ip+封cookie+重点关照[我这里有一句mmp一定要讲]）

附上勉强能用的代码（自己根据实际情况，选择代理ip和休眠时间）

PS：获取代理ip代码：gei_ip_pools在置顶文章里面

from selenium import webdriver
import requests
import time
from bs4 import BeautifulSoup
import re
from mysql_py import *
import threading
from urllib import request
from get_ip_pools import *
import random#get cookie
def get_cookies():driver = webdriver.Chrome()driver.get("http://weixin.sogou.com/")driver.find_element_by_xpath('//*[@id="loginBtn"]').click()time.sleep(10)cookies = driver.get_cookies()cookie = {}for items in cookies:cookie[items.get('name')] = items.get('value')return cookie#url = "http://weixin.sougou.com"
#response = requests.get(url,cookies = cookie)
#search = input("输入你想搜索的关键词")#get total url
def get_total_url(url):if url.startswith("//"):url = "http:" + urlelif url.startswith("/"):url = "http:/" + urlelse:url = urlreturn url#init header

-----------------------调用，一部分是淘宝店铺的，同样在置顶文章中------------------------分割线：两部分代码

from final_test import *
from mysql_py import *
import threading
from sougou_wechat import *
#choice
choice = input('''输入需要获取的数据:a.淘宝店铺b.公众号文章''')
if choice == 'a':db,db_cursor = init_fun("taobao")check_tab_exist(db,db_cursor)href_list = get_item_href()for i in range(len(href_list)):start_url = href_list[i]get_shop_url(store_list,start_url)for shop_url in store_list:print(shop_url)t = threading.Thread(target = get_img_url,args = (shop_url,db,db_cursor))t.start()#t.join()#阻塞待定elif choice == 'b':db,db_cursor = init_fun("weixin")check_tab_exist(db,db_cursor)my_cookie = get_cookies()    search = input("输入你想搜索的关键词")page_num = get_page_count(search,my_cookie)main_fun(page_num,search,my_cookie,db,db_cursor)

插入了对数据库的操作，可以自己选择性保留
