之前看到了这道shell面试题:获取51CTO博客列表按时间倒序排序http://oldboy.blog.51cto.com/2561410/1860985
由于学了一段时间的python,试想着能否使用python来解题
思路:通过requests模块获取网页源码,通过split()函数获取总页数,拼接字符串获取所有博客地址的url。同样,通过requests获取所有页面的源码并通过正则匹配,获取关键信息,从而拼接出html页面。
#coding:utf-8 import requests import re,sys reload(sys) sys.setdefaultencoding(‘utf-8‘) # 获取页数 def page(): url = ‘http://oldboy.blog.51cto.com/all/2561410‘ content = requests.get(url).content msg = re.findall(r‘<center>(.*)</center>‘,content)[0] return msg.split(‘/‘)[-1].split()[0] # 获取关键信息并拼接html def oldboy(): uri = ‘http://oldboy.blog.51cto.com/all/2561410/page/‘ num = page() res = [] for i in range(int(num)): url = uri + str(int(i)+1) content = requests.get(url).content res += re.findall(r‘<a href="(/\d+/\d+)">(.*)</a>‘,content) # res格式[(‘/2561410/1867160‘,‘2017\xd7\xee\xd0\xc2\xc6\xf3\xd2\xb5Shell\xc3\xe6\xca\xd4\xcc\xe2\xbc\xb0\xc6\xf3\xd2\xb5\xd4\xcb\xce\xac\xca\xb5\xd5\xbd\xb9\xb230\xb5\xc0\xb0\xb8\xc0\xfd‘),...] html = ‘‘ for i in res: msg = i[1].decode(‘gbk‘) href = ‘http://oldboy.blog.51cto.com‘+i[0] html += "<p><br></p><p>{0}</p><p><a href=‘{1}‘ target=‘_blank‘>{1}</a></p>".format(msg,href) # html格式"<p><br></p><p>2017最新企业Shell面试题及企业运维实战共30道案例</p><p><a href=‘http://oldboy.blog.51cto.com/2561410/1867160‘ target=‘_blank‘>http://oldboy.blog.51cto.com/2561410/1867160</a></p>..." with open(‘oldboy_blog.html‘,‘w‘) as f: f.write(html) if __name__==‘__main__‘: oldboy()
