Python抓取電影天堂電影信息的代碼

更新時間：2016年04月07日 21:36:30 作者：itjh

最近想做一個電影資訊的App，由于豆瓣不對外開發(fā)API了，正愁怎么錄入數(shù)據(jù)呢。最近在學(xué) Python 想想那就用它來抓取電影信息吧

Python2.7Mac OS

抓取的是電影天堂里面最新電影的頁面。鏈接地址： http://www.dytt8.net/html/gndy/dyzz/index.html

獲取頁面的中電影詳情頁鏈接

import urllib2
import os
import re
import string


# 電影URL集合
movieUrls = []


# 獲取電影列表
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="(.*?)" 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])

抓取詳情頁中的電影數(shù)據(jù)

def queryMovieInfo(movieUrls):

 for index, item in enumerate(movieUrls):

 print('電影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] + ""
  # 截取名稱
  movieName = movieName[movieName.find("《") + 3:movieName.find("》")]
 else:
  movieName = ""

 print("電影名稱: " + 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("電影發(fā)布時間: " + movieDate[-10:])

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

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

  # 刪除<br />標簽
  movieInfo = movieInfo.replace("<br />","")

  # 根據(jù) ◎ 符號拆分

  movieInfo = movieInfo.split('◎')

 else:
  movieInfo = ""

 print("電影基礎(chǔ)信息: ")

 for item in movieInfo:
  print(item)


 # 電影海報
 pattern = re.compile('<img.*? src="(.*?)".*? />', re.S)		
 movieImg = re.findall(pattern,movieContent[0])

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

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

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

 print("電影下載地址：" + movieDownUrl + "")

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

執(zhí)行抓取

if __name__=='__main__':

  print("開始抓取電影數(shù)據(jù)");
 
  queryMovieList()
  print(len(movieUrls))

  queryMovieInfo(movieUrls)
  print("結(jié)束抓取電影數(shù)據(jù)")

總結(jié)

學(xué)好正則表達式很重要,很重要,很重要!!!! Python的語法好有感覺, 對比Java …
