HTTP::Body(3)

NAME
HTTP::Body - HTTP Body Parser

SYNOPSIS
    use HTTP::Body;

    sub handler : method {
        my ( $class, $r ) = @_;

        my $content_type   = $r->headers_in->get('Content-Type');
        my $content_length = $r->headers_in->get('Content-Length');

        my $body   = HTTP::Body->new( $content_type, $content_length );
        my $length = $content_length;

        while ( $length ) {

            $r->read( my $buffer, ( $length < 8192 ) ? $length : 8192 );

            $length -= length($buffer);

            $body->add($buffer);
        }

        my $uploads     = $body->upload;     # hashref
        my $params      = $body->param;      # hashref
        my $param_order = $body->param_order # arrayref
        my $body        = $body->body;       # IO::Handle
    }

DESCRIPTION
HTTP::Body parses chunks of HTTP POST data and supports application/octet-stream, application/x-www-form-urlencoded, and multipart/form-data.

Chunked bodies are supported by not passing a length value to new().

It is currently used by Catalyst to parse POST bodies.

NOTES
When parsing multipart bodies, temporary files are created to store any uploaded files. You must delete these temporary files yourself after processing them, or set $body->cleanup(1) to automatically delete them at DESTROY-time.

METHODS

new Constructor. Takes content type and content length as parameters, returns a HTTP::Body object.

add Add string to internal buffer. Will call spin unless done. returns length before adding self.

body
    accessor for the body.

chunked
    Returns 1 if the request is chunked.

cleanup
    Set to 1 to enable automatic deletion of temporary files at DESTROY-time.

content_length
    Returns the content-length for the body data if known. Returns -1 if the request is chunked.

content_type
    Returns the content-type of the body data.

init
    return self.

length
    Returns the total length of data we expect to read if known. In the case of a chunked request, returns the amount of data read so far.

trailing_headers
    If a chunked request body had trailing headers, trailing_headers will return an HTTP::Headers object populated with those headers.

spin
    Abstract method to spin the io handle.

state
    Returns the current state of the parser.

param
    Get/set body parameters.

upload
    Get/set file uploads.

tmpdir
    Specify a different path for temporary files. Defaults to the system temporary path.

param_order
    Returns the array ref of the param keys in the order how they appeared on the body
