NAME

Catalyst::Plugin::Authentication::Credential::HTTP - Superseded / deprecated module providing HTTP Basic and Digest authentication for Catalyst applications.

SYNOPSIS

use Catalyst qw/
    Authentication
    Authentication::Store::Minimal
    Authentication::Credential::HTTP
/;

__PACKAGE__->config->{authentication}{http}{type} = 'any'; # or 'digest' or 'basic'
__PACKAGE__->config->{authentication}{users} = {
    Mufasa => { password => "Circle Of Life", },
};

sub foo : Local {
    my ( $self, $c ) = @_;

    $c->authorization_required( realm => "foo" ); # named after the status code ;-)

    # either user gets authenticated or 401 is sent

    do_stuff();
}

# with ACL plugin
__PACKAGE__->deny_access_unless("/path", sub { $_[0]->authenticate_http });

sub end : Private {
    my ( $self, $c ) = @_;

    $c->authorization_required_response( realm => "foo" );
    $c->error(0);
}

DEPRECATION NOTICE

Please note that this module is DEPRECATED, it has been Superseded by Catalyst::Authentication::Credential::HTTP, please use that module in any new projects.

Porting existing projects to use the new module should also be easy, and if there are any facilities in this module which you cannot see how to achieve in the new module then please contact the maintainer as this is a bug and will be fixed.

Let me say that again: THIS MODULE IS NOT SUPPORTED, use Catalyst::Authentication::Credential::HTTP instead.

DESCRIPTION

This moduule lets you use HTTP authentication with Catalyst::Plugin::Authentication. Both basic and digest authentication are currently supported.

When authentication is required, this module sets a status of 401, and the body of the response to 'Authorization required.'. To override this and set your own content, check for the $c->res->status == 401 in your end action, and change the body accordingly.

TERMS

Nonce

A nonce is a one-time value sent with each digest authentication request header. The value must always be unique, so per default the last value of the nonce is kept using Catalyst::Plugin::Cache. To change this behaviour, override the store_digest_authorization_nonce and get_digest_authorization_nonce methods as shown below.

METHODS

authorization_required %opts

Tries to authenticate_http, and if that fails calls authorization_required_response and detaches the current action call stack.

This method just passes the options through untouched.

authenticate_http %opts

Looks inside $c->request->headers and processes the digest and basic (badly named) authorization header.

This will only try the methods set in the configuration. First digest, then basic.

See the next two methods for what %opts can contain.

authenticate_basic %opts

authenticate_digest %opts

Try to authenticate one of the methods without checking if the method is allowed in the configuration.

%opts can contain store (either an object or a name), user (to disregard %the username from the header altogether, overriding it with a username or user %object).

authorization_required_response %opts

Sets $c->response to the correct status code, and adds the correct header to demand authentication data from the user agent.

Typically used by authorization_required, but may be invoked manually.

%opts can contain realm, domain and algorithm, which are used to build %the digest header.

store_digest_authorization_nonce $key, $nonce

get_digest_authorization_nonce $key

Set or get the $nonce object used by the digest auth mode.

You may override these methods. By default they will call get and set on $c->cache.

get_http_auth_store %opts

CONFIGURATION

All configuration is stored in YourApp->config->{authentication}{http}.

This should be a hash, and it can contain the following entries:

store

Either a name or an object -- the default store to use for HTTP authentication.

type

Can be either any (the default), basic or digest.

This controls authorization_required_response and authenticate_http, but not the "manual" methods.

authorization_required_message

Set this to a string to override the default body content "Authorization required."

RESTRICTIONS

When using digest authentication, this module will only work together with authentication stores whose User objects have a password method that returns the plain-text password. It will not work together with Catalyst::Authentication::Store::Htpasswd, or Catalyst::Plugin::Authentication::Store::DBIC stores whose password methods return a hashed or salted version of the password.
