python在多玩图片上下载妹子图的实现代码

代码如下:
# -*- coding:utf-8 -*-
import httplib
import urllib
import string
import re
def getContent():                   #从网站中获取所有内容
 conn = httplib.HTTPConnection("tu.duowan.com")
 conn.request("GET", "/m/meinv/index.html")
 r = conn.getresponse()
 print r.status, r.reason
 data1 = r.read()#.decode('utf-8') #编码根据实际情况酌情处理
 return data1

def getImageUrl(data):            #将获取到img链接写到sour.txt文件中国
 sour = open("test//sour.txt", 'w')
 pplen = len("http://s1.dwstatic.com/group1/M00/37/2A/e2c30e89184ea942a4be9c1f7ba217a5.jpg")
 for i in range(len(data) - 3):
  if data[i] == 'i' and data[i + 1] == 'm' and data[i + 2] == 'g':
   for j in xrange(i + 9, i + 9 + pplen):
    sour.write(data[j])
   sour.write('/n')
 sour.close()

def downImage():               #根据test//sour.txt里面的url自动下载图片
 tt = 0    #name
 sour = open('test//sour.txt')
 while 1:
  line = sour.readline()
  if line:
   Len = len(line)
   #print Len
   if line[Len - 2] == 'g' and line[Len - 3] == 'p' and line[Len - 4] == 'j':
    path = line
    data = urllib.urlopen(line).read()
    f = open('test//' + str(tt) + '.jpg', 'wb')
    f.write(data)
    f.close()
    tt = tt + 1
  else:
   break
 sour.close()

content = getContent()
getImageUrl(content)
downImage()
