NAME

Plack::Request::WithEncoding - Subclass of Plack::Request which supports encoding.

SYNOPSIS

use Plack::Request::WithEncoding;

my $app_or_middleware = sub {
    my $env = shift; # PSGI env

    # Example of $env
    #
    # $env = {
    #     QUERY_STRING   => 'query=%82%d9%82%b0', # <= encoded by 'cp932'
    #     REQUEST_METHOD => 'GET',
    #     HTTP_HOST      => 'example.com',
    #     PATH_INFO      => '/foo/bar',
    # };

    my $req = Plack::Request::WithEncoding->new($env);

    $req->env->{'plack.request.withencoding.encoding'} = 'cp932'; # <= specify the encoding method.

    # If `$req->env->{'plack.request.withencoding.encoding'}` is undef (namely, the encoding method is not specified),
    # then this library will use `utf-8` as encoding method.

    my $query = $req->param('query'); # <= get parameters of 'query' that is decoded by 'cp932'.

    my $res = $req->new_response(200); # new Plack::Response
    $res->finalize;
};

DESCRIPTION

Plack::Request::WithEncoding is the subclass of Plack::Request. This module supports the encoding for requests, the following attributes will return decoded request values.

ATTRIBUTES

• encoding

  Returns a encoding method to use to decode parameters.

• query_parameters

  Returns a reference to a hash containing decoded query string (GET) parameters. This hash reference is Hash::MultiValue object.

• body_parameters

  Returns a reference to a hash containing decoded posted parameters in the request body (POST). As with query_parameters, the hash reference is a Hash::MultiValue object.

• parameters

  Returns a Hash::MultiValue hash reference containing decoded (and merged) GET and POST parameters.

• param

  Returns decoded GET and POST parameters with a CGI.pm-compatible param method. This is an alternative method for accessing parameters in $req->parameters. Unlike CGI.pm, it does not allow setting or modifying query parameters.

    $value  = $req->param( 'foo' );
    @values = $req->param( 'foo' );
    @params = $req->param;
  

• raw_query_parameters

  This attribute is the same as query_parameters of Plack::Request.

• raw_body_parameters

  This attribute is the same as body_parameters of Plack::Request.

• raw_parameters

  This attribute is the same as parameters of Plack::Request.

• raw_param

  This attribute is the same as param of Plack::Request.

REQUEST ENVIRONMENTS of Plack

You can specify the encoding method, like so;

$req->env->{'plack.request.withencoding.encoding'} = 'utf-7'; # <= set utf-7

And this encoding method will be used to decode.

Default encoding method is utf-8. If $req->env->{'plack.request.withencoding.encoding'} is undef then default encoding method will be used.
