[OpenLayers-Users] Strange behaviourwithOpenLayers.Request.POSTand MapServer

[David Alda Fernandez de Lezea]

Hi Christopher, 

I started making it yesterday afternoon, and I came to the end that using php with my PHP knowledge was definitely the problem. So I decided to make an ASP script, I've done things like this before, and manage to get work a standalone script. My source code is like this:

<%
	dim strURL, xmlhttp, strMethod, strData
	
	'Response.End
	'strURL = request.querystring("url")
	'strMethod = request.querystring("method")
	'strData = request.querystring("data")
	
	strURL = "http://192.168.1.65/cgi-bin/mapserv.exe?map=../htdocs/MFD/ejemplo_wfs.map&"
	strMethod = "POST"
	strData = "<?xml version='1.0'?><wfs:GetFeature service='WFS' version='1.1.0' outputFormat='text/xml; subtype=gml/3.1.1' xmlns:wfs='http://www.opengis.net/wfs' xmlns:ogc='http://www.opengis.net/ogc' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:schemaLocation='http://www.opengis.net/wfs ../wfs/1.1.0/WFS.xsd'><wfs:Query typeName='RecintosSigpac'><PropertyName>msGeometry</PropertyName><Filter><Or><And><PropertyIsEqualTo><PropertyName>PROVINCIA</PropertyName><Literal>1</Literal></PropertyIsEqualTo><PropertyIsEqualTo><PropertyName>MUNICIPIO</PropertyName><Literal>1</Literal></PropertyIsEqualTo><PropertyIsEqualTo><PropertyName>POLIGONO</PropertyName><Literal>1</Literal></PropertyIsEqualTo><PropertyIsEqualTo><PropertyName>PARCELA</PropertyName><Literal>1</Literal></PropertyIsEqualTo><PropertyIsEqualTo><PropertyName>RECINTO</PropertyName><Literal>1</Literal></PropertyIsEqualTo></And><And><PropertyIsEqualTo><PropertyName>PROVINCIA</PropertyName><Literal>1</Literal></PropertyIsEqualTo><PropertyIsEqualTo><PropertyName>MUNICIPIO</PropertyName><Literal>1</Literal></PropertyIsEqualTo><PropertyIsEqualTo><PropertyName>POLIGONO</PropertyName><Literal>1</Literal></PropertyIsEqualTo><PropertyIsEqualTo><PropertyName>PARCELA</PropertyName><Literal>86</Literal></PropertyIsEqualTo><PropertyIsEqualTo><PropertyName>RECINTO</PropertyName><Literal>1</Literal></PropertyIsEqualTo></And></Or></Filter></wfs:Query></wfs:GetFeature>"

	
    Set xmlhttp = Server.CreateObject("Msxml2.ServerXMLHTTP")   
    xmlhttp.setTimeouts 30000,30000,30000,30000
    
    'xmlhttp.Open "GET", strURL
	xmlhttp.Open strMethod, strURL

    xmlhttp.setRequestHeader "Man", strMethod & strURL & " HTTP/1.1"
    xmlhttp.setRequestHeader "Content-Type", "text/xml; charset=utf-8"
    
	xmlhttp.send(strData)
		
    If xmlhttp.Status = 200 Then	     

	   'response.write xmlhttp.readyState
	   'response.write "--------------------"
	   response.write xmlhttp.responseText
	   'response.write xmlhttp.responseXML
	end if  
	
%>

But now, I can't figure out how to integrate this with OL. Should I use OpenLayers.Request.Post?? How?? Cuz I've try to do it but without success, maybe I'm doing something wrong.

My javascriot request:

OpenLayers.Request.POST({url: "http://192.168.1.65:8090/proxygis/proxygis.asp?", callback: callbackFunction, params: {data: escape(filtro), url: escape(this.onlineResource), method: "POST"}});

But it doesn't even appear in Firebug the request...

Hope you can help me.

Thanks.

Un saludo,

Ah. Yeah. If the same URL is working without the proxy, I would suspect the proxy :) I had missed that in your earlier emails.

I would recommend trying to write a standalone PHP script that successfully sends a request; have you done that yet? (When I say standalone, I mean something that doesn't take parameters from the URL; just hardcoded values).
