Equivalent implementation of curl request using urllib2

Question

I have a curl command:

curl -H 'XXX:1' -b headerinfo https:.....com/getinfo

However, I want to do the same thing using Python. I tried the following:

with open('headerinfo', 'r') as headerfile:
    newData = headerfile.read()

req = urllib2.Request("https:....com/getinfo ", newData)
req.add_header('XXX', '1')
res2 = urllib2.urlopen(req)

However, the above code does not work. Is there something I am missing that is preventing my code from working?

Answer 1

-b option is used to send cookies to a web server. If the value of -b is name=value, it'll be sent as cookie otherwise the value is used as file name of cookie data.

To send cookies you have to create an opener.

import cookielib, urllib2
cj = cookielib.MozillaCookieJar()
cj.load('headerinfo')
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
opener.addheaders.append(('XXX','1'))
response = opener.open("http://example.com/")
