  # Parse
  my $res = Mojo::Message::Response->new;
  $res->parse("HTTP/1.0 200 OK\x0d\x0a");
  $res->parse("Content-Length: 12\x0d\x0a");
  $res->parse("Content-Type: text/plain\x0d\x0a\x0d\x0a");
  $res->parse('Hello World!');
  say $res->code;
  say $res->headers->content_type;
  say $res->body;

  # Build
  my $res = Mojo::Message::Response->new;
  $res->code(200);
  $res->headers->content_type('text/plain');
  $res->body('Hello World!');
  say $res->to_string;

DESCRIPTION

Mojo::Message::Response is a container for HTTP responses, based on RFC 7230 <http://tools.ietf.org/html/rfc7230> and RFC 7231 <http://tools.ietf.org/html/rfc7231>.

EVENTS

Mojo::Message::Response inherits all events from Mojo::Message.

ATTRIBUTES

Mojo::Message::Response inherits all attributes from Mojo::Message and implements the following new ones.

code

  my $code = $res->code;
  $res     = $res->code(200);

HTTP response status code.

max_message_size

  my $size = $res->max_message_size;
  $res     = $res->max_message_size(1024);

Maximum message size in bytes, defaults to the value of the "MOJO_MAX_MESSAGE_SIZE" environment variable or 2147483648 (2GiB). Setting the value to 0 will allow messages of indefinite size.

message

  my $msg = $res->message;
  $res    = $res->message('OK');

HTTP response status message.

METHODS

Mojo::Message::Response inherits all methods from Mojo::Message and implements the following new ones.

cookies

  my $cookies = $res->cookies;
  $res        = $res->cookies(Mojo::Cookie::Response->new);
  $res        = $res->cookies({name => 'foo', value => 'bar'});

Access response cookies, usually Mojo::Cookie::Response objects.

  # Names of all cookies
  say $_->name for @{$res->cookies};

default_message

  my $msg = $res->default_message;
  my $msg = $res->default_message(418);

Generate default response message for status code, defaults to using ``code''.

  my $bool = $res->extract_start_line(\$str);

Extract status-line from string.

fix_headers

  $res = $res->fix_headers;

Make sure response has all required headers.

get_start_line_chunk

  my $bytes = $res->get_start_line_chunk($offset);

Get a chunk of status-line data starting from a specific position. Note that this method finalizes the response.

  my $bool = $res->is_client_error;

Check if this response has a "4xx" status ``code''.

start_line_size

  my $size = $req->start_line_size;

Size of the status-line in bytes. Note that this method finalizes the response.
