DESCRIPTION

Plack::Response allows you a way to create PSGI response array ref through a simple API.

METHODS

new

  $res = Plack::Response->new;
  $res = Plack::Response->new($status);
  $res = Plack::Response->new($status, $headers);
  $res = Plack::Response->new($status, $headers, $body);

Creates a new Plack::Response object.

status

  $res->status(200);
  $status = $res->status;

Sets and gets HTTP status code. code is an alias.

headers

  $headers = $res->headers;
  $res->headers([ 'Content-Type' => 'text/html' ]);
  $res->headers({ 'Content-Type' => 'text/html' });
  $res->headers( HTTP::Headers->new );

Sets and gets HTTP headers of the response. Setter can take either an array ref, a hash ref or HTTP::Headers object containing a list of headers.

body

  $res->body($body_str);
  $res->body([ "Hello", "World" ]);
  $res->body($io);

Gets and sets HTTP response body. Setter can take either a string, an array ref, or an IO::Handle-like object. content is an alias.

header

  $res->header('X-Foo' => 'bar');
  my $val = $res->header('X-Foo');

Shortcut for $res->headers->header.

content_type, content_length, content_encoding

  $res->content_type('text/plain');
  $res->content_length(123);
  $res->content_encoding('gzip');

Shortcut for the equivalent get/set methods in $res->headers.

redirect

  $res->redirect($url);
  $res->redirect($url, 301);

Sets redirect URL with an optional status code, which defaults to 302.

location

Gets and sets Location header.

cookies

  $res->cookies->{foo} = 123;
  $res->cookies->{foo} = { value => '123' };

Returns a hash reference containing cookies to be set in the response. The keys of the hash are the cookies' names, and their corresponding values are a plain string (for value with everything else defaults) or a hash reference that can contain keys such as value, domain, expires, path, httponly, secure.

expires can take a string or an integer (as an epoch time) and does not convert string formats such as +3M.

  $res->cookies->{foo} = {
      value => 'test',
      path  => "/",
      domain => '.example.com',
      expires => time + 24 * 60 * 60,
  };
