1、Python中獲取整個(gè)頁(yè)面的代碼：

import requestsres = requests.get(’https://blog.csdn.net/yirexiao/article/details/79092355’)res.encoding = ’utf-8’print(res.text)

2、運(yùn)行結(jié)果

實(shí)例擴(kuò)展：

from bs4 import BeautifulSoupimport time,re,urllib2t=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()-tscanpage(http://news.163.com/)
