Hi, About WFS-T I have no knowledge, because I use MapServer, which doesn't support that.

Can you please let me know what service context you were using the requests in? (Ie where you able to update/insert features to a WFS-T using this approach?). Pure .ASP, too! Keep it real brother.

Instead of Request.Form to get the post data, one have to use Request.BinaryRead. Source : http://www.bigresource.com/Tracker/Track-asp-zMoQgx8B/ Below the code snippet, that works for me: Dim requestMethod, strParams, strRequest, strURL, lngByteSize requestMethod = Request.ServerVariables("REQUEST_METHOD") strParams = Request.QueryString lngByteSize = Request.TotalBytes strRequest = BytesToText(Request.BinaryRead(lngByteSize)) 'not working 'strRequest = Request.Form strURL = MapserverUrl & strParams Dim objHTTP set objHTTP = CreateObject("MSXML2.ServerXMLHTTP") objHTTP.open "POST", strURL, false objHTTP.setRequestHeader "Content-Type", "application/xml; charset=UTF-8" '"application/x-www-form-urlencoded" objHTTP.send strRequest Response.write objHTTP.responseText set objHTTP = nothing 'Quelle : http://www.bigresource.com/Tracker/Track-asp-zMoQgx8B/ Function BytesToText(strBytes) Dim lngLength, lngIndex, lngAsciiCode strAsciiText = "" lngLength = LenB(strBytes) For lngIndex = 1 To lngLength lngAsciiCode = AscB(MidB(strBytes, lngIndex, 1)) strAsciiText = strAsciiText & Chr(lngAsciiCode) Next BytesToText = strAsciiText End Function Here is the application, where I use this approach: http://gis.ibbeck.de/ginfo/apps/Landtagswahl_NRW_2010/Wahlen_NRW_2010.asp Arnd -----Ursprüngliche Nachricht----- Von: [email protected] [mailto:[email protected]] Im Auftrag von Arnd Wippermann Gesendet: Donnerstag, 9.

I'm not able to catch the request of the control with asp. Request.Form contains nothing and results in the mentioned MapServer message ... WCS Server does not support XML POST requests ... If I try a script with OpenLayers.Request.issue for testing with the same post parameter, then the asp-script get the post parameter and sending this to MapServer and retrieving the response works as expected. Is there something specific with the OpenLayers.Protocol.WFS, so that the asp-script get the post parameter?

Basically, the setup is MapServer and OpenLayers. I have two pages, both are exactly the same with the exception that one calls mapserver on Port 81 (Apache) and the other calls Mapserver on Port 81 via an asp page using MSXML2.ServerXMLHTTP to hide the mapfile string and its location. This method is documented here: http://mapserver.org/ogc/wms_server.html (3.On IIS servers (Windows), you can use the following ASP script ..... etc). OpenLayers.Layer.WFS works fine on both setups as this uses GET requests but this will be deprecated in version 3, see here: http://dev.openlayers.org/docs/files/OpenLayers/Layer/WFS-js.html. I am trying to port the setup so that it uses OpenLayers.Layer.Vector with OpenLayers.Protocol.WFS which uses POST as opposed to GET. This works fine with the setup that calls Apache directly on port 81 but does not work using MSXML2.ServerXMLHTTP in the asp page. When I say that it works fine with Apache, it returns valid GML but there's no geometry which, I believe, is sorted in MapServer 5.6.4 - I am using 5.6.3 in the latest MS4W package. The method using MSXML2.ServerXMLHTTP (see the first link above) converts everything to GET but I have changed the code to use post as follows: ============================================================= Set xmlhttp = Server.CreateObject("MSXML2.ServerXMLHTTP") Select Case Request.ServerVariables("REQUEST_METHOD") Case "GET" strRequest = Request.QueryString MapserverUrl = "<url>mapserv.exe?MAP=<map file>.map&" & strRequest xmlhttp.open "GET", MapServerURL, False xmlhttp.send ' Case "POST" strRequest = Request.Form MapserverUrl = "<url>mapserv.exe?MAP=<map file>" xmlhttp.Open "POST", MapserverUrl, False Set SendDoc = server.createobject("Microsoft.XMLDOM") SendDoc.ValidateOnParse= True SendDoc.LoadXML(strRequest) 'Various header types (All tried at different times) 'xmlhttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded" 'xmlhttp.setRequestHeader "Content-Type", "application/xml" //OpenLayers 'xmlhttp.setRequestHeader "Content-Type","text/xml" 'Two ways of sending xml (Both tried) 'xmlhttp.send strRequest xmlhttp.send Sendoc End Select Response.ContentType = xmlhttp.getResponseHeader("content-type") Response.BinaryWrite xmlhttp.responseBody Set xmlhttp = Nothing ============================================================= I have tried everything I can think of including setting a variable that contains the xml within the code above, i.e. it isn't sent from the html page with the map, to no avail. The closest I can get to it working is a response (as shown in Firebug) as follows: ============================================================= <?xml version='1.0' encoding="ISO-8859-1" ?> <ServiceExceptionReport version="1.2.0" xmlns="http://www.opengis.net/ogc"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.opengis.net/ogc http://schemas.opengis.net/wfs/1.0.0/OGC-exception.xsd";> <ServiceException code="InvalidParameterValue" locator="filter"> msWFSGetFeature(): WFS server error.

I also get the following when using the Request.Form from the map page: ============================================================= <?xml version='1.0' encoding="ISO-8859-1" ?> <ServiceExceptionReport version="1.2.0" xmlns="http://www.opengis.net/ogc"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.opengis.net/ogc http://schemas.opengis.net/wcs/1.0.0/OGC-exception.xsd";> <ServiceException>msWCSParseRequest(): WCS server error. WCS Server does not support XML POST requests, please use KVP. </ServiceException> </ServiceExceptionReport> ============================================================= What I want to get using MSXML2.ServerXMLHTTP is the same response as I get using the method that calls MapServer on port 81 i.e. I should get valid GML without the geometry. OpenLayers uses MSXML2.ServerXMLHTTP for the POST and all I am really trying to do is pass that request through another MSXML2.ServerXMLHTTP to MapServer. This is be quite basic I think but I have spent hours on the problem and have visited everything that I possibly can on Google without success. I suppose that someone who knows about MSXML2.ServerXMLHTTP might be the person to ask but I am hopeful that someone in the MapServer or the OpenLayers community might have cracked this problem. I'm stumped! HELP PLEASE!!! Many thanks. Regards, Donald Kerr P.S. Please don't tell me to use Apache directly! I know that this may be a solution that would work but I want to solve this one and I want to have IIS on port 80 for other stuff and MS4w on Port 81 for maps. _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users
