NAME

POE::Filter::HTTPD - convert stream to HTTP::Request; HTTP::Response to stream

SYNOPSIS

  $httpd = POE::Filter::HTTPD->new();
  $arrayref_with_http_response_as_string =
    $httpd->put($full_http_response_object);
  $arrayref_with_http_request_object =
    $line->get($arrayref_of_raw_data_chunks_from_driver);

DESCRIPTION

The HTTPD filter parses the first HTTP 1.0 request from an incoming stream into an HTTP::Request object (if the request is good) or an HTTP::Response object (if the request was malformed). To send a response, give its put() method a HTTP::Response object.

Here is a sample input handler:

  sub got_request {
    my ($heap, $request) = @_[HEAP, ARG0];

    # The Filter::HTTPD generated a response instead of a request.
    # There must have been some kind of error.  You could also check
    # (ref($request) eq 'HTTP::Response').
    if ($request->isa('HTTP::Response')) {
      $heap->{wheel}->put($request);
      return;
    }

    # Process the request here.
    my $response = HTTP::Response->new(200);
    $response->push_header( 'Content-Type', 'text/html' );
    $response->content( $request->as_string() );

    $heap->{wheel}->put($response);
  }

Please see the documentation for HTTP::Request and HTTP::Response.

Streaming Media

It is perfectly possible to use Filter::HTTPD for streaming output media. Even if it's not possible to change the input filter from Filter::HTTPD, by setting the output_filter to Filter::Stream and omitting any content in the HTTP::Response object.

  $wheel->put($response); # Without content, it sends just headers.
  $wheel->set_output_filter(POE::Filter::Stream->new());
  $wheel->put("Raw content.");
