做个小练习，抓取的是电影天堂里面最新电影的页面。链接地址：http://www.dytt8.net/html/gndy/dyzz/index.html

首先我们需要获取里面电影详情的网页地址：

import urllib2
import os
import re
import string


# 电影URL集合
movieUrls = []


# 获取电影列表
def queryMovieList():

    url = ‘http://www.dytt8.net/html/gndy/dyzz/index.html‘   
    conent = urllib2.urlopen(url)
    conent =  conent.read()
    conent = conent.decode(‘gb2312‘,‘ignore‘).encode(‘utf-8‘,‘ignore‘)  
    pattern = re.compile (‘<div class="title_all"><h1><font color=#008800>.*?</a>></font></h1></div>‘+
                          ‘(.*?)<td height="25" align="center" bgcolor="#F4FAE2"> ‘,re.S)
    items = re.findall(pattern,conent) 
    
    str = ‘‘.join(items)
    pattern = re.compile (‘<a href="http://www.mamicode.com/(.*?)" class="ulink">(.*?)</a>.*?<td colspan.*?>(.*?)</td>‘,re.S)
    news = re.findall(pattern, str)

    for  j in news:
       
            movieUrls.append(‘http://www.dytt8.net‘+j[0])

抓取详情页中的电影数据

def queryMovieInfo(movieUrls):

    for index, item in enumerate(movieUrls):

        print(‘电影URL: ‘ + item)

        conent = urllib2.urlopen(item)
        conent = conent.read()
        conent = conent.decode(‘gb2312‘,‘ignore‘).encode(‘utf-8‘,‘ignore‘)  


        movieName = re.findall(r‘<div class="title_all"><h1><font color=#07519a>(.*?)</font></h1></div>‘, conent, re.S)
        if (len(movieName) > 0):
            movieName = movieName[0] + ""
            # 截取名称
            movieName = movieName[movieName.find("《") + 3:movieName.find("》")]
        else:
            movieName = ""

        print("电影名称: " + movieName.strip())

        movieContent = re.findall(r‘<div class="co_content8">(.*?)</tbody>‘,conent , re.S)


        pattern = re.compile(‘<ul>(.*?)<tr>‘, re.S)
        movieDate = re.findall(pattern,movieContent[0])

        if (len(movieDate) > 0):
            movieDate = movieDate[0].strip() + ‘‘
        else:
            movieDate = ""

        print("电影发布时间: " + movieDate[-10:])

        pattern = re.compile(‘<br /><br />(.*?)<br /><br /><img‘)
        movieInfo = re.findall(pattern, movieContent[0])

        if (len(movieInfo) > 0):
            movieInfo = movieInfo[0]+‘‘

            # 删除<br />标签
            movieInfo = movieInfo.replace("<br />","")

            # 根据 ◎ 符号拆分

            movieInfo = movieInfo.split(‘◎‘)

        else:
            movieInfo = ""

        print("电影基础信息: ")

        for item in movieInfo:
            print(item)


        # 电影海报
        pattern = re.compile(‘<img.*? src="http://www.mamicode.com/(.*?)".*? />‘, re.S)        
        movieImg = re.findall(pattern,movieContent[0])

        if (len(movieImg) > 0):
            movieImg = movieImg[0]
        else:
            movieImg = ""
 
        print("电影海报: " + movieImg)

        pattern = re.compile(‘<td style="WORD-WRAP: break-word" bgcolor="#fdfddf"><a href="http://www.mamicode.com/(.*?)">.*?</a></td>‘, re.S)
        movieDownUrl = re.findall(pattern,movieContent[0])

        if (len(movieDownUrl) > 0):
            movieDownUrl = movieDownUrl[0]
        else:
            movieDownUrl = ""

        print("电影下载地址：" + movieDownUrl + "")

        print("------------------------------------------------\n\n\n")

执行抓取

if __name__==‘__main__‘:


     print("开始抓取电影数据");
     
     queryMovieList()

     print(len(movieUrls))


     queryMovieInfo(movieUrls)

     print("结束抓取电影数据")
