import httplib, urllib
params =          


        

Answer 1

Their server seems to want you to acquire the proper cookie. This works:

import urllib, urllib2, cookielib

cookie_jar = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookie_jar))
urllib2.install_opener(opener)

# acquire cookie
url_1 = 'http://www.bkstr.com/webapp/wcs/stores/servlet/BuybackMaterialsView?langId=-1&catalogId=10001&storeId=10051&schoolStoreId=15828'
req = urllib2.Request(url_1)
rsp = urllib2.urlopen(req)

# do POST
url_2 = 'http://www.bkstr.com/webapp/wcs/stores/servlet/BuybackSearch'
values = dict(isbn='9780131185838', schoolStoreId='15828', catalogId='10001')
data = urllib.urlencode(values)
req = urllib2.Request(url_2, data)
rsp = urllib2.urlopen(req)
content = rsp.read()

# print result
import re
pat = re.compile('Title:.*')
print pat.search(content).group()

# OUTPUT: Title:  Statics & Strength of Materials for Arch (w/CD)
