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 containers, based on RFC 7230
       <http://tools.ietf.org/html/rfc7230> and RFC 7231 <http://tools.ietf.org/html/rfc7231>,
       like Mojo::Content::MultiPart and Mojo::Content::Single.

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.

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

ATTRIBUTES

       Mojo::Content implements the following attributes.

   auto_decompress
         my $bool = $content->auto_decompress;
         $content = $content->auto_decompress($bool);

       Decompress content automatically if "is_compressed" is true.

   auto_relax
         my $bool = $content->auto_relax;
         $content = $content->auto_relax($bool);

       Try to detect when relaxed parsing is necessary.

   expect_close
         my $bool = $content->expect_close;
         $content = $content->expect_close($bool);

       Expect a response that is terminated with a connection close.

   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 (256KiB).

   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 (256KiB).

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

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

   skip_body
         my $bool = $content->skip_body;
         $content = $content->skip_body($bool);

       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 $bool = $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.

   charset
         my $charset = $content->charset;

       Extract charset from "Content-Type" header.

   clone
         my $clone = $content->clone;

       Return a new Mojo::Content object cloned from this 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. Note that this method
       finalizes the content.

   header_size
         my $size = $content->header_size;

       Size of headers in bytes. Note that this method finalizes the content.

   headers_contain
         my $bool = $content->headers_contain('foo bar baz');

       Check if headers contain a specific string. Note that this method finalizes the content.

   is_chunked
         my $bool = $content->is_chunked;

       Check if "Transfer-Encoding" header indicates chunked transfer encoding.

   is_compressed
         my $bool = $content->is_compressed;

       Check "Content-Encoding" header for "gzip" value.

   is_dynamic
         my $bool = $content->is_dynamic;

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

   is_finished
         my $bool = $content->is_finished;

       Check if parser is finished.

   is_limit_exceeded
         my $bool = $content->is_limit_exceeded;

       Check if buffer has exceeded "max_buffer_size".

   is_multipart
         my $bool = $content->is_multipart;

       False, this is not a Mojo::Content::MultiPart object.

   is_parsing_body
         my $bool = $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;
         $content = $content->write('');
         $content = $content->write($bytes);
         $content = $content->write($bytes => sub {...});

       Write dynamic content non-blocking, the optional drain callback will be executed once all
       data has been written. Calling this method without a chunk of data will finalize the
       "headers" and allow for dynamic content to be written later. You can write an empty chunk
       of data at any time to end the stream.

         # Make sure previous chunk of data has been written before continuing
         $content->write('He' => sub {
           my $content = shift;
           $content->write('llo!' => sub {
             my $content = shift;
             $content->write('');
           });
         });

   write_chunk
         $content = $content->write_chunk;
         $content = $content->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 executed once all data has been written. Calling this method without a
       chunk of data will finalize the "headers" and allow for dynamic content to be written
       later. You can write an empty chunk of data at any time to end the stream.

         # Make sure previous chunk of data has been written before continuing
         $content->write_chunk('He' => sub {
           my $content = shift;
           $content->write_chunk('llo!' => sub {
             my $content = shift;
             $content->write_chunk('');
           });
         });
