This module provides a bunch of methods to manage HTTP cookies.


item

my $cookies = HTTP::Cookies.new(
    autosave => 1,
    :file<./cookies.here>
);


method set-cookie(HTTP::Cookies:, Str $str)


Adds a cookie (passed as an argument $str of type Str) to the list of cookies.


my $cookies = HTTP::Cookies.new;
$cookies.set-cookie('Set-Cookie: name1=value1; HttpOnly');


my $cookies = HTTP::Cookies.new;
$cookies.set-cookie('Set-Cookie: name1=value1; HttpOnly');
$cookies.save;


my $cookies = HTTP::Cookies.new;
$cookies.load;


method extract-cookies(HTTP::Cookies:, HTTP::Response $response)


Gets cookies ('Set-Cookie: ' lines) from the HTTP Response and adds it to the list of cookies.


my $cookies = HTTP::Cookies.new;
my $response = HTTP::Response.new(Set-Cookie => "name1=value; Secure");
$cookies.extract-cookies($response);


method add-cookie-header(HTTP::Cookies:, HTTP::Request $request)


Adds cookies fields ('Cookie: ' lines) to the HTTP Request.


my $cookies = HTTP::Cookies.new;
my $request = HTTP::Request.new;
$cookies.load;
$cookies.add-cookie-header($request);


my $cookies = HTTP::Cookies.new;
$cookies.set-cookie('Set-Cookie: name1=value1; Secure');
$cookies.set-cookie('Set-Cookie: name2=value2; Expires=Wed, 09 Jun 2021 10:18:14 GMT');
$cookies.clear-expired; # contains 'name1' cookie only


my $cookies = HTTP::Cookies.new;
$cookies.load; # contains something
$cookies.clear; # will be empty after this action


method push-cookie(HTTP::Cookies:, HTTP::Cookie $c)


Pushes cookies (passed as an argument $c of type HTTP::Cookie) to the list of cookies.


my $c = HTTP::Cookie.new(:name<a>, :value<b>, :httponly);
my $cookies = HTTP::Cookies.new;
$cookies.push-cookie: $c;


Returns all cookies in human (and server) readable form.
