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 $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 $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 specfic 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 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_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\r\n\r\nHello 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.
