Python 2.7_Second_try_爬取阳光电影网_获取电影下载地址并写入文件 20161207

1、昨天文章http://www.cnblogs.com/Mr-Cxy/p/6139705.html 是获取电影网站主菜单 然后获取每个菜单下的电影url 

2、今天是对电影url 进行再次解析获取下载地址 并写入文件  

 

4、python 代码 

#coding:utf-8
import requests
from bs4 import BeautifulSoup as bs

#爬取入口
rooturl="http://www.ygdy8.com/index.html"
#获取网页源码
res=requests.get(rooturl)
#网站编码gb2312
res.encoding='gb2312'
#网页源码
html=res.text
soup=bs(html,'html.parser')
cate_urls = []
for cateurl in soup.select('.contain ul li a'):
    #网站分类标题
    cate_name=cateurl.text.encode('utf-8')
    #分类url 进行再次爬取
    cate_url="http://www.ygdy8.com/"+ cateurl['href']
    cate_urls.append(cate_url)
    print "网站一级菜单:",cate_name,"菜单网址：",cate_url
    # newdir = "E:/moive24/"+ cate_name
    # os.makedirs(newdir.decode("utf-8"))
    # print "创建分类目录成功------" + newdir
#每个菜单url 解析
for i in range(len(cate_urls)):
    cate_listurl=cate_urls[i]
    res = requests.get(cate_listurl)
    res.encoding = 'gb2312'
    html = res.text
    soup = bs(html, 'html.parser')
    print "正在解析第"+str(i+1)+"个链接",cate_urls[i]
    contenturls=[]
    contents=soup.select('.co_content8 ul')[0].select('a')
    #print contents
    for title in contents:
        moivetitle=title.text.encode('utf-8')
        moiveurl="http://www.ygdy8.com/"+ title['href']
        contenturls.append(moiveurl)
        print moivetitle,moiveurl
        # file_name=newdir +'/'+ moivetitle +'.txt'
        # print file_name
        # f = open(file_name.decode("utf-8"), "wb")
        # f.close()
        res = requests.get(moiveurl)
        res.encoding = 'gb2312'
        html = res.text
        soup = bs(html, 'html.parser')
        moive_sources=soup.select('#Zoom span tbody tr td a')
        for source in moive_sources:
            moive_source=source['href']
            #print moive_source
            f=open('E:/moive24/moive.txt','a')
            f.write(moive_source.encode("utf-8") + "\n")
            f.close
