import requests
import sys
import argparse

# use argparse to get command line argument
# --username (or -u) and --password (or -p) are required
parser = argparse.ArgumentParser(description='Process parameters.')
parser.add_argument('-u', '--username', required=True)
parser.add_argument('-p', '--password', required=True)
parser.add_argument('-o', '--output', type=argparse.FileType('w'), required=True)
args = parser.parse_args()

# connect to delicious and retrieve cookies
data = {"action": "login", "username": args.username, "password": args.password}
response = requests.post("https://delicious.com/login", data=data)
cookies = response.cookies

# export bookmarks

args.output.write(unicode(response.content).encode("utf-8"))
