[OpenLayers-Users] Strange behaviour withOpenLayers.Request.POST and MapServer

David,

Thanks for your response. The strange thing is that I've got a TEMPLATE defined at Layer level in MapServer's mapfile:

LAYER
			DEBUG 5
			NAME "RecintosSigpac"
			PROJECTION
				"init=epsg:23030"
			END

				STYLE

				END
				TEMPLATE "ms_template.html"
			END
			
			
			STATUS ON
		END # Layer

The thing is that with the following instruction:

OpenLayers.Request.POST({url: this.onlineResource, callback: callbackFunction, data: filter});

Having this.onlineResource = http://192.168.1.65/cgi-bin/mapserv.exe?map=../htdocs/MFD/ejemplo_wfs.map&
data = filter for getFeature Request

I don't have any troubles, I get the features correctly. But when I try to make the same request over the proxy, that's when then troubles come:

OpenLayers.Request.POST({url: networkSettings.proxyURL, callback: callbackFunction, params: {url: this.onlineResource, method: "POST", data: filter}});

Having:

networkSettings.proxyURL = http://192.168.1.65/webproxy.php?
filter = filter for getFeature Request

I've tried, also, to use the parameter proxy but without success, in fact, I don't get anything, no error, no response, nothing at all.

Apache log:

Maybe there is something wrong with webproxy.php???

Thanks in advance.

David, 

I just skimmed the text of post XML, but if your OpenLayers app is sending a query to MapServer, your layer will need a template.  In the case of WFS, I don't think that you need a real template file.  But, you still might need an entry  in your LAYER that is something like TEMPLATE "dummy.html".

David.

Subject: [mapserver-users] RV: [OpenLayers-Users] Strange behaviour with OpenLayers.Request.POST and MapServer 


Hi list,

I posted this question in OpenLayers mailing list but without response, maybe here someone knwos what could be happening. I'm trying to load some data from a remote WFS Server (MapServer). At the beginning I used OpenLayers.Request.POST({url: this.onlineResource, callback: callbackFunction, method: 'POST', data: filter}); to load the features and it worked perfectly, but now, due to some architecture issues, I have to make the request over a proxy script made in php, but I don't get the features. I don't get any OpenLayers error but I get an error from MapServer:

Error:
mapserv(): Web application error. Traditional BROWSE mode requires a TEMPLATE in the WEB section, but none was provided.

Request: 

OpenLayers.Request.POST({url: networkSettings.proxyURL + "?method=POST&url=" + escape(this.onlineResource) + "&data=" + filtro, callback: callbackFunction, method: 'POST', headers: {"Content-Type": "text/xml; charset=utf-8"}});

Web Proxy:

<?

	$strURL = @$_REQUEST["url"];
	$strMethod = @$_REQUEST["method"];
	$strData = @$_REQUEST["data"];

	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL, $strURL);
	if ($strMethod == "POST"){
		curl_setopt($ch, CURLOPT_POST, 1);
		curl_setopt($ch, CURLOPT_POSTFIELDS, $strData);
	}
	
	$data = curl_exec($ch);
	curl_close($ch);
	
?>

In Firebug I can see all the parameters:

data	<?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>

And in Apache access.log I get :

This seems to be OK, isn't it?

Am I doing something wrong with the new request??
 
Thanks in advance.
