Mojo::Content(3p)

NAME
Mojo::Content - HTTP 1.1 content base class

SYNOPSIS
  use Mojo::Base 'Mojo::Content';

DESCRIPTION
Mojo::Content is an abstract base class for HTTP 1.1 content as described in RFC 2616.

EVENTS
Mojo::Content can emit the following events.

  "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);
  });

  "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');
  });

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

Emitted when a new chunk of content arrives.

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

ATTRIBUTES
Mojo::Content implements the following attributes.

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

Try to detect broken web servers and turn on relaxed parsing automatically.

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

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

  "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 HTTP 0.9 and responses that are terminated with a connection close.

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 $string = $content->build_body;

Render whole body.

  "build_headers"
  my $string = $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 $chunk = $content->generate_body_chunk(0);

Generate dynamic content.

  "get_body_chunk"
  my $chunk = $content->get_body_chunk(0);

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

  "get_header_chunk"
  my $chunk = $content->get_header_chunk(13);

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

  "has_leftovers"
  my $success = $content->has_leftovers;

Check if there are leftovers.

  "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_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_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\r\n\r\nHello World!");

Parse content chunk.

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

Parse body chunk.

  "parse_body_once"
  $content = $content->parse_body_once("Hi!");

Parse body chunk once.

  "parse_until_body"
  $content = $content->parse_until_body(
    "Content-Length: 12\r\n\r\nHello World!"
  );

Parse chunk and stop after headers.

  "progress"
  my $size = $content->progress;

Size of content already received from message in bytes.

  "write"
  $content->write('Hello!');
  $content->write('Hello!', sub {...});

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

  "write_chunk"
