HTTP::Cookies to Mojo::UserAgent::CookieJar

Question

I have $cookie_jar which created using HTTP::Cookies:

$cookie_jar = HTTP::Cookies->new(
  file => "my$path/my_cookies.dat",
  autosave => 1,
);

I want to use this $cookie_jar using Mojo::UserAgent but didn't find an option, the only option I see is parsing raw string:

my $cookies = $cookie->parse($str);

Answer 1

I've uploaded a new version of HTTP::Cookies::Mozilla and it includes a sample program that solves this issue.

Load your data using HTTP::Cookie then convert it whatever format that you like by calling scan with a callback:

$cookie_jar = HTTP::Cookies->new(
  file => "my$path/my_cookies.dat",
  autosave => 1,
);
$cookie_jar->scan( \&callback )

Inside that callback, convert it to the Mojo::Cookie::Response object:

{
my $jar = Mojo::UserAgent::CookieJar->new

# access the scoped variable after you've run all the callbacks.
sub jar { $jar }

sub callback {
    my( $version, $key, $val, $path, $domain, $port, 
        $path_spec, $secure, $expires, $discard, $hash ) = @_;

    my $cookie = Mojo::Cookie::Response->new;
    ...fill in data...

    $jar->add( $mojo_cookie);
    )
}

Alternately, write a subclass of HTTP::Cookies that reads your format the HTTP::Cookies way but populates a Mojo::CookieJar instead. It's not that hard (and I've written several such things, some of which are on CPAN).

HTTP::Cookies also has the as_string method which makes a multi-line string with one cookie per string. You can use those lines to feed into Mojo::Cookie to re-parse them, but that's not as appealing to me.

Answer 2

They are not compatible objects, and nothing other than HTTP::Cookies can read the file it creates. You need to use a Mojo::UserAgent::CookieJar with Mojo::UserAgent. Note that it will create one by default, accessed via $ua->cookie_jar. It does not have file serialization support, but the Persistent role can add this functionality -- it still will not read the HTTP::Cookies format however.
