NAME

HTTP::MultiPartParser - HTTP MultiPart Parser

SYNOPSIS

    $parser = HTTP::MultiPartParser->new(
        boundary  => $boundary,
        on_header => $on_header,
        on_body   => $on_body,
    );
    
    while ($octets = read_octets_from_body()) {
        $parser->parse($octets);
    }
    
    $parser->finish;

DESCRIPTION

This class provides a low-level API for processing MultiPart MIME data streams conforming to MultiPart types as defined in RFC 2616.

IMPORTANT: This is an early release intended primarily for feedback from people who have discussed it. The API is still subject to change. The documentation is not complete, please see eg/example.pl for an example.

METHODS

new

    $parser = HTTP::MultiPartParser->new( %attributes );
    

This constructor returns a instance of HTTP::MultiPartParser. Valid attributes inculde:

  • boundary (Mandatory)

        boundary => $value

    The unquoted and unescaped boundary parameter value from the Content-Type header field. The boundary parameter value consist of a restricted set of characters as defined in RFC 2046.

        DIGIT / ALPHA / "'" / "(" / ")" /
        "+" / "_" / "," / "-" / "." /
        "/" / ":" / "=" / "?"
  • on_header (Mandatory)

        on_header => $callback->($header)

    This callback will be invoked when the header of a part has successfully been received. The callback will only be invoked once for each part.

  • on_header_as

        on_header_as => 'unparsed' | 'lines'

    Defines the $header value for the on_header callback.

    • unparsed

      Callback invoked with an octet string containing the unparsed header.

    • lines

      Callback invoked with an ARRAY reference, where each element of the array is a header line. Folding whitespace is removed from all lines and header continuation lines are unwrapped.

  • on_body (Mandatory)

        on_body => $callback->($chunk, $final)

    This callback will be invoked when there is any data available for the body of a part. The callback may be invoked multiple times for each part.

  • on_error

        on_error => $callback->($message)

    This callback will be invoked anytime an error occurs in the parser. After receiving an error the parser is no longer useful in its current state.

  • max_preamble_size

        max_preamble_size => 32768
  • max_header_size

        max_header_size => 32768

parse

    $parser->parse($octets);

Parses the given octets.

finish

    $parser->finish;

Finish the parsing.

reset

    $parser->reset;
