A url looks like:
http://www.example.com/cgi-bin/blahblah?&PC=abd23423&uy=020
I need to extract the value: abc23423
I tried this regex but its not working:
rx = re.compile(r'PC=(\w*)&uy=')
I then I did:
pc = rx.search(url).groups()
but I get an error:
attribute error: nonetype object has no attribute groups.
尝试urlparse 。
Update
Sheesh. What was I thinking?
import urlparse
u = 'http://www.example.com/cgi-bin/blahblah?&PC=abd23423&uy=020'
query = urlparse.urlparse(u).query
urlparse.parse_qs(query) # {'PC': ['abd23423'], 'uy': ['020']}
Original Answer
This code snippet worked for me. Take a look:
import urlparse, re
u = 'http://www.example.com/cgi-bin/blahblah?&PC=abd23423&uy=020'
query = urlparse.urlparse(u).query
pattern = re.compile('PC=(\w*)&uy')
pattern.findall(query) # ['abd23423']
lol = "http://www.example.com/cgi-bin/blahblah?&PC=abd23423&uy=020"
s = re.compile("&PC=(\w+)&uy=")
g = s.search(lol)
g.groups()
('abd23423',)
This seems to work for me.
