Mojo::Content(3pm) User Contributed Perl Documentation Mojo::Content(3pm) 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 Hello 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 Hello 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.
