PDF print password protected page (ideally if wkhtmltopdf uses a cookie)

I'm trying to print a password-protected PDF page with wkhtmltopdf

, but I can't load the (working) cookie, meaning I always just print the "login" page.

Saving cookie after login

The following code works as expected: if I log in, I can view the correct pages, whether I loaded from a cookie or entered my login details:

class PrintPages(object):
    def __init__(self):
        ...
        self.browser = mechanize.Browser()
        self.cj = mechanize.MozillaCookieJar()
        self.browser.set_cookiejar(self.cj)
        self.login("cookies.txt")

    def login(self, cookie_jar):
        """ Log in, save cookie if doesn't exist. Otherwise, load cookie. """
        if os.path.isfile(cookie_jar):
            self.cj.load(cookie_jar, ignore_discard=True, ignore_expires=True)
        else:
            self.browser.open(self.login_url)

            self.browser.select_form(name="loginform")
            self.browser["username"] = self.username
            self.browser["password"] = getpass.getpass()

            self.browser.submit()
            self.cj.save(cookie_jar, ignore_discard=True, ignore_expires=True)

      

        
        
        
      

    

(cookies.txt)

    # Netscape HTTP Cookie File
    # http://www.netscape.com/newsref/std/cookie_spec.html
    # This is a generated file!  Do not edit.

sub.example.com  FALSE   /   TRUE        JSESSIONID  B8307A77925DB287B0346C728BBF8F24

      

        
        
        
      

    

However, by reporting either wget

or wkhtmltopdf

to download cookies, you will get a login page.

$ wget -p --load-cookies cookies.txt sub.example.com/page.html
$ wkhtmltopdf --cookie-jar cookies.txt sub.example.com/page.html page.pdf

      

        
        
        
      

    

What gives? Ideally, any solution that allows me to print to PDF would be ideal, but I'm curious what is going on here.

I use:

• wkhtmltopdf
  
  version 0.9.9
• mechanize
  
  : version 0.2.5
