简单糗事百科(一)

好久没写python，今天放假，无聊来回忆一下以前学习的时候写的爬虫，无奈正则已经忘光了。。。幸好最后还是写了出来，代码如下：

import urllib
import urllib2
import re
page = 1 
url = "http://www.qiushibaike.com/hot/page/" + str(page)
user_agent = 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.101 Safari/537.36'
headers = {'User-Agent' : user_agent}
try:
    request = urllib2.Request(url, headers = headers)
    response = urllib2.urlopen(request)
    content = response.read().decode('utf-8')
    pattern = re.compile(r'
\s*(?P.*?)\s*
')
    items = re.findall(pattern, content)
#print content
    for item in items:
        print item
except urllib2.URLError, e:
    if hasattr(e, "code"):
        print e.code
    if hasattr(e, "reason"):
        print e.reason
