NAME

Mojo::Content - HTTP content base class

SYNOPSIS

  package Mojo::Content::MyContent;
  use Mojo::Base 'Mojo::Content';

  sub body_contains  {...}
  sub body_size      {...}
  sub get_body_chunk {...}

DESCRIPTION

Mojo::Content is an abstract base class for HTTP content as described in RFC 2616.

EVENTS

Mojo::Content inherits all events from Mojo::EventEmitter and can emit the following new ones.

body

  $content->on(body => sub {
    my $content = shift;
    ...
  });

Emitted once all headers have been parsed and the body starts.

  $content->on(body => sub {
    my $content = shift;
    $content->auto_upgrade(0) if $content->headers->header('X-No-MultiPart');
  });

drain

  $content->on(drain => sub {
    my ($content, $offset) = @_;
    ...
  });

Emitted once all data has been written.

  $content->on(drain => sub {
    my $content = shift;
    $content->write_chunk(time);
  });

read

  $content->on(read => sub {
    my ($content, $bytes) = @_;
    ...
  });

Emitted when a new chunk of content arrives.

  $content->unsubscribe('read');
  $content->on(read => sub {
    my ($content, $bytes) = @_;
    say "Streaming: $bytes";
  });

ATTRIBUTES

Mojo::Content implements the following attributes.

auto_relax

  my $relax = $content->auto_relax;
  $content  = $content->auto_relax(1);

Try to detect when relaxed parsing is necessary.

headers

  my $headers = $content->headers;
  $content    = $content->headers(Mojo::Headers->new);

Content headers, defaults to a Mojo::Headers object.

max_buffer_size

  my $size = $content->max_buffer_size;
  $content = $content->max_buffer_size(1024);

Maximum size in bytes of buffer for content parser, defaults to the value of the MOJO_MAX_BUFFER_SIZE environment variable or 262144.

max_leftover_size

  my $size = $content->max_leftover_size;
  $content = $content->max_leftover_size(1024);

Maximum size in bytes of buffer for pipelined HTTP requests, defaults to the value of the MOJO_MAX_LEFTOVER_SIZE environment variable or 262144.

relaxed

  my $relaxed = $content->relaxed;
  $content    = $content->relaxed(1);

Activate relaxed parsing for responses that are terminated with a connection close.

skip_body

  my $skip = $content->skip_body;
  $content = $content->skip_body(1);

Skip body parsing and finish after headers.

METHODS

Mojo::Content inherits all methods from Mojo::EventEmitter and implements the following new ones.

body_contains

  my $success = $content->body_contains('foo bar baz');

Check if content contains a specific string. Meant to be overloaded in a subclass.

body_size

  my $size = $content->body_size;

Content size in bytes. Meant to be overloaded in a subclass.

boundary

  my $boundary = $content->boundary;

Extract multipart boundary from Content-Type header.

build_body

  my $str = $content->build_body;

Render whole body.

build_headers

  my $str = $content->build_headers;

Render all headers.

charset

  my $charset = $content->charset;

Extract charset from Content-Type header.

clone

  my $clone = $content->clone;

Clone content if possible, otherwise return undef.

generate_body_chunk

  my $bytes = $content->generate_body_chunk(0);

Generate dynamic content.

get_body_chunk

  my $bytes = $content->get_body_chunk(0);

Get a chunk of content starting from a specific position. Meant to be overloaded in a subclass.

get_header_chunk

  my $bytes = $content->get_header_chunk(13);

Get a chunk of the headers starting from a specific position.

header_size

  my $size = $content->header_size;

Size of headers in bytes.

is_chunked

  my $success = $content->is_chunked;

Check if content is chunked.

is_compressed

  my $success = $content->is_compressed;

Check if content is gzip compressed.

is_dynamic

  my $success = $content->is_dynamic;

Check if content will be dynamically generated, which prevents clone from working.

is_finished

  my $success = $content->is_finished;

Check if parser is finished.

is_limit_exceeded

  my $success = $content->is_limit_exceeded;

Check if buffer has exceeded max_buffer_size.

is_multipart

  my $false = $content->is_multipart;

False.

is_parsing_body

  my $success = $content->is_parsing_body;

Check if body parsing started yet.

leftovers

  my $bytes = $content->leftovers;

Get leftover data from content parser.

parse

  $content
    = $content->parse("Content-Length: 12\x0d\x0a\x0d\x0aHello World!");

Parse content chunk.

parse_body

  $content = $content->parse_body('Hi!');

Parse body chunk and skip headers.

progress

  my $size = $content->progress;

Size of content already received from message in bytes.

write

  $content = $content->write($bytes);
  $content = $content->write($bytes => sub {...});

Write dynamic content non-blocking, the optional drain callback will be invoked once all data has been written.

write_chunk

  $content = $content->write_chunk($bytes);
  $content = $content->write_chunk($bytes => sub {...});

Write dynamic content non-blocking with chunked transfer encoding, the optional drain callback will be invoked once all data has been written.
