例子:
代码语言:javascript复制import requests
from bs4 import BeautifulSoup
def getHTMLText(url):
try:
r = requests.get(url, timeout = 30)
r.raise_for_status()
#r.encoding = 'utf-8'
return r.text
except:
return ""
def getContent(url):

# print(html)
soup = BeautifulSoup(html, "html.parser")
title = soup.select("div.hd > h1")
print(title[0].get_text())
time = soup.select("div.a_Info > span.a_time")
print(time[0].string)
author = soup.select("div.qq_articleFt > div.qq_toolWrap > div.qq_editor")
print(author[0].get_text())
paras = soup.select("div.Cnt-Main-Article-QQ > p.text")
for para in paras:
if len(para) > 0:
print(para.get_text())
print()
#写入文件
fo = open("text.txt", "w ")
fo.writelines(title[0].get_text() "n")
fo.writelines(time[0].get_text() "n")
for para in paras:
if len(para) > 0:
fo.writelines(para.get_text() "nn")
fo.writelines(author[0].get_text() 'n')
fo.close()
#将爬取到的文章用字典格式来存
article = {
'Title' : title[0].get_text(),
'Time' : time[0].get_text(),
'Paragraph' : paras,
'Author' : author[0].get_text()
}
print(article)
def main():
