SOLVED: minimal ruby mapserver GetCapabilities (was Re: [UMN_MAPSERVER-USERS] ruby mapscript: bug in Makefile + GetCapabilities return zlitch !)

[s duclos]

Hi,

I'm following up on myself for googlers .. 

Bellow is a minimal WMS/mapserver in ruby
that send back to the browser the capabilities
of the WMS server. No .map or any other config.
It work in OpenEV also.


Cheers,

Sylvain.

#!/usr/bin/ruby

require 'webrick'
include WEBrick

require "mapscript"
include Mapscript

WMS_proc = lambda do |req, resp|
  resp['Content-Type'] = "text/xml"

  map = MapObj.new()
  map.setMetaData( "ows_onlineresource",
"http://dummy.org/" )

  wxsReq = OWSRequest.new()
  wxsReq.setParameter("SERVICE", "WMS")
  wxsReq.setParameter("VERSION", "1.1.1")
  wxsReq.setParameter("REQUEST", "GetCapabilities")

  msIO_installStdoutToBuffer()
  ret = map.OWSDispatch(wxsReq)
  resp.body = msIO_getStdoutBufferBytes().to_s
end

WMS = HTTPServlet::ProcHandler.new(WMS_proc)

s = HTTPServer.new(:Port => 2000)
s.mount("/WMS",   WMS)

trap("INT"){ s.shutdown }
s.start
