1、Python中获取整个页面的代码: importrequestsres=requests.get('https://blog.csdn.net/yirexiao/article/details/79092355')res.encoding='utf-8'print(res.text) 2、运行结果 实例扩展: from bs4 import BeautifulSoupimport ti

import requests res = requests.get('https://blog.csdn.net/yirexiao/article/details/79092355') res.encoding = 'utf-8' print(res.text)
2、运行结果
实例扩展:
from bs4 import BeautifulSoup import time,re,urllib2 t=time.time() websiteurls={} def scanpage(url): websiteurl=url t=time.time() n=0 html=urllib2.urlopen(websiteurl).read() soup=BeautifulSoup(html) pageurls=[] Upageurls={} pageurls=soup.find_all("a",href=True) for links in pageurls: if websiteurl in links.get("href") and links.get("href") not in Upageurls and links.get("href") not in websiteurls: Upageurls[links.get("href")]=0 for links in Upageurls.keys(): try: urllib2.urlopen(links).getcode() except: print "connect failed" else: t2=time.time() Upageurls[links]=urllib2.urlopen(links).getcode() print n, print links, print Upageurls[links] t1=time.time() print t1-t2 n+=1 print ("total is "+repr(n)+" links") print time.time()-t scanpage(http://news.163.com/)
