获取百度搜索结果的真实url以及摘要和时间

利用requests库和bs4实现，demo如下：

#coding:utf-8
import requests
from bs4 import BeautifulSoup
import bs4
import re
headers = {
    'User-Agent':'Chrome/68.0.3440.106'
}

def getHTMLText(url):
    try:
        r=requests.get(url,headers=headers)
        r.raise_for_status()
        r.encoding=r.apparent_encoding
        return r.text
    except:
        return ''
'''
def getHref(html):
    soup=BeautifulSoup(html,'lxml')
    for node in soup.find_all()
'''
def bdurlCode(url):
    res = requests.get(url, allow_redirects=False)
    Real_url = res.headers['location']
    return Real_url

def fillList(ulist,html):
    soup=BeautifulSoup(html,'lxml')
    for node in soup.find_all('div', {'class': 'result c-container '}):
        abstract_node = node.find('div',{'class':'c-abstract'})
        cite_node = node.find('a', {'class': 'c-showurl'})
        time_node=node.find('span',{'class':' newTimeFactor_before_abs m'})
        if not time_node:continue
        url=cite_node['href']
        url=bdurlCode(url)
        abstract=abstract_node.text
        time=time_node.text
        ulist.append([url,time,abstract])
    print(ulist)
    print(len(ulist))
