Reading Firefox 3.x cookies in Python

I found the following code snippet on my hard drive today. It allows you to access Firefox 3.x cookies in Python. Firefox 3.x moved away from the older text file format to a sqlite database.

This code is useful if you want to access something behind an authentication gateway and you also access the page through your web browser. You can also use this code to convert a sqlite database into a cookie file CURL can read.

I didn’t write this code, it was written by Noah Fontes when we where doing some scraping of the Google Summer of Code website (before I joined Google).

    from cStringIO import StringIO
    from pysqlite2 import dbapi2 as sqlite
 
    con = sqlite.connect(filename)
 
    cur = con.cursor()
    cur.execute("select host, path, isSecure, expiry, name, value from moz_cookies")
 
    ftstr = ["FALSE","TRUE"]
 
    s = StringIO()
    s.write("""\

    for item in cur.fetchall():
        s.write("%s\t%s\t%s\t%s\t%s\t%s\t%s\n" % (
            item[0], ftstr[item[0].startswith('.')], item[1],
            ftstr[item[2]], item[3], item[4], item[5]))
 
    s.seek(0)
 
    cookie_jar = cookielib.MozillaCookieJar()
    cookie_jar._really_load(s, '', True, True)
    return cookie_jar
