in PHP MapScript should be something like
$map->setMetaData("ows_enable_request", "*");
in Python:
map.setMetaData("ows_enable_request", "*")

it goes in map->web->metadata
I guessed as much, but I can't fathom the syntax. The webObj doesn't seem to
have any constructor, and I don't see any documentation. Could you please point
me to an example?

a bit more investigation on producing a WMS response via Perl MapScript reveals
the following error
<?xml version='1.0' encoding="ISO-8859-1" standalone="no" ?>
<!DOCTYPE ServiceExceptionReport SYSTEM

<ServiceExceptionReport version="1.1.0">
<ServiceException>
msWMSDispatch(): WMS server error. WMS request not enabled. Check
wms/ows_enable_request settings.
</ServiceException>
</ServiceExceptionReport>
So, it seems I have to somehow, somewhere enable 'ows_enable_request'. Looking
at the documentation, seems like if I had a map file, I could add the following
line to do so
ows_enable_request '*'
However, I am not using a map file at all. Not finding any documentation on
this setting, I tried the following to no avail
$map->{ows_enable_request} = '*';
Suggestions, anyone?

I would really appreciate insight from someone well-versed in the ins and outs
of WMS via MapScript. Looking at the discussion at
[http://trac.osgeo.org/mapserver/ticket/670], the `img = wms_map.draw()` step
seems to be a crucial part of drawing the image.
So, I added `my $img = $map->draw();` to my code below, and indeed, the image
was drawn and sent back to the browser.
Is this something that should be added to the examples in the documentation? Is
this the right way to do things? In any case, I am not write to STDOUT, and
sending the buffer directly. Instead, my code is very much like a regular
request (and it works) --
my $new_extent = $map->{extent};
my $req = new mapscript::OWSRequest();
$req->setParameter( "SERVICE", "WMS" );
$req->setParameter( "VERSION", "1.1.0" );
$req->setParameter( "REQUEST", "GetMap" );
$req->setParameter( "BBOX", "-180,-90,180,90" );
$req->setParameter( "LAYERS", "layer_name");
$req->setParameter( "SRS", "-1");
$req->setParameter( "WIDTH", "1200");
$req->setParameter( "HEIGHT", "600");
my $dispatch_out = $map->OWSDispatch( $req );
my $img = $map->draw();
my $map_img = 'test_' . sprintf("%0.10d", rand(1000000000)) . '.png';
$img->save("/path/to/$map_img");
return send_file("/path/to/$map_img");
Comments? Corrections?

I am trying to convert my MapScript program to a WMS responder. I create my
$map where I set all the layers and classes and colors, etc, just like for a
normal, non-WMS request that works perfectly correctly.
my $map = undef;
$map = mapObj(name => 'mymap') unless defined $map;
my $req = new mapscript::OWSRequest();
$req->setParameter( "SERVICE", "WMS" );
$req->setParameter( "VERSION", "1.1.0" );
$req->setParameter( "REQUEST", "GetCapabilities" );
I changed the above line to
$req->setParameter( "REQUEST", "GetMap");
but, still no improvement.
mapscript::msIO_installStdoutToBuffer();
my $dispatch_out = $map->OWSDispatch( $req );
printf "%s\n", mapscript::msIO_getStdoutBufferString();
Except, the above doesn't really do anything for me. I get nothing in my
browser. Suggestions?
