Logging in and using cookies in pycurl

Question

I need to download a file that is on a password protected page. To get to the page manually I first have to authenticate via an ordinary login page. I want to use curl to fetc

You should store cookie first and then read from it:

C.setopt(pycurl.COOKIEJAR, 'cookie.txt')
C.setopt(pycurl.COOKIEFILE, 'cookie.txt')

Here what curl --help returned:

-b, --cookie STRING/FILE  String or file to read cookies from (H)
-c, --cookie-jar FILE  Write cookies to this file after operation (H)

See this sample:

def connect(self):
    '''
    Connect to NGNMS server
    '''
    host_url = self.ngnms_host + '/login'

    c = pycurl.Curl()
    c.setopt(c.URL, host_url)
    c.setopt(pycurl.TIMEOUT, 10)

    c.setopt(pycurl.FOLLOWLOCATION, 1)
    c.setopt(pycurl.POSTFIELDS, 'j_username={ngnms_user}&j_password={ngnms_password}'.format(**self.ngnms_login))
    c.setopt(pycurl.COOKIEJAR, 'data/ngnms.cookie')

    # c.setopt(c.VERBOSE, True)

    c.setopt(pycurl.SSL_VERIFYPEER, 0);
    session = c
    return session
