NAME
Mojo::Content - HTTP content base class
SYNOPSIS
use Mojo::Base 'Mojo::Content';
DESCRIPTION
Mojo::Content is an abstract base class for HTTP 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 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_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
$content->write_chunk('Hello!');
$content->write_chunk('Hello!', sub {...});
Write dynamic content non-blocking with chunked
transfer encoding, the optional drain callback will be invoked once all data has been written.
