使用Python find函数和urllib下载图片。
A：
#!/usr/bin/env python
import time
import urllib
i = 0
url = ['']*10
name = ['']*10
con = urllib.urlopen('http://www.ithome.com/html/bizhi/164396.htm').read()
src = con.find(r'/newsuploadfiles')
end = con.find(r'.jpg',src)
name[0] = con[src +24 :end +1]
while src != -1 and end != -1 and i < 10:
url[0] = con[src -21 :end +4]
src = con.find(r'/newsuploadfiles',end)
end = con.find(r'.jpg',src)
content = urllib.urlopen(url[0]).read()
open(r'img/'+ name[0]+'jpg','w+').write(content)
name[0] = con[src +24 :end +1]
print url[0]
time.sleep(3)
i = i + 1
else:
print "Download Over!"B：
#!/usr/bin/env python
import re
import urllib

i = 0
for imgurl in imglist:
name = imgurl[45:]
print name
content = urllib.urlopen(imgurl).read()
open(r'tmp/' + name,'w+').write(content)
i = i + 1
html = getHtml("http://www.ithome.com/html/bizhi/164396.htm")
