Using mimetools.Message in urllib2.urlopen

I'm using urllib2.urlopen():

req = urllib2.Request('http://www.google.com')
resp = urllib2.urlopen(req)
print resp.info()

print resp.info(开发者_运维知识库)['set-cookie']

As you can see in the headers received in the response, there are TWO statements of 'set-cookie', HOWEVER in the resp.info() object I receive it has grouped both cookie statements together and separates them by a ',' (comma)

This is troublesome to separate the cookies by this delimiter since there are commas inside the cookie information i'm try to separate with this comma delimiter

Is there an easy way to call upon each cookie string individually with this mimetools.message object? (resp.info())

else-> I'll just have to parse the headers manually without this not so helpful mimetools.message/dictionary object

Try using getheaders() to get a list of the cookies:

>>> msg = resp.info()
>>> msg.getheaders('Set-Cookie')
['PREF=ID=5975a5ee255f0949:FF=0:TM=1305336283:LM=1305336283:S=1vkES6eF4Yxd-_oM; expires=Mon, 13-May-2013 01:24:43 GMT; path=/; domain=.google.com.au', 'NID=46=lQVFZg6yKUsoWT529Hqp5gA8B_CKYd2epPIbANmw_J0UzeMt2BhuMF-gtmGsRhenUTeajKz2zILXd9xWpHWT8ZGvDcmNdkzaGX-L_-sKyY1w4e2l3DKd80JzSkt2Vp-H; expires=Sun, 13-Nov-2011 01:24:43 GMT; path=/; domain=.google.com.au; HttpOnly']

In this case, you get a list of two strings.

Then you can iterate over that list and grab whichever cookie you like. str.startswith() is your friend:

>>> cookies = msg.getheaders('Set-Cookie')
>>> for cookie in cookies:
...     if cookie.startswith('PREF='):
...             print 'Got PREF: ', cookie
...     else:
...             print 'Got another: ', cookie
... 
Got PREF:  PREF=ID=5975a5ee255f0949:FF=0:TM=1305336283:LM=1305336283:S=1vkES6eF4Yxd-_oM; expires=Mon, 13-May-2013 01:24:43 GMT; path=/; domain=.google.com.au
