[Chameleon] Extract WFS Data

[Dave Findlay]

Hi Bart,

Thanks for the advice.  I've tried things two ways in my mapfile

1.  

##########################################
MAP


WEB

  METADATA
		"wfs_title"     "WMS Demo Server" 
		"wfs_onlineresource" "http://127.0.0.1/cgi-bin/mapserv.exe?"
		"wfs_srs"               "NAD83:401"  
  END
END

LAYER #  Start of Boundaries Layer

    NAME Boundaries 
    CONNECTIONTYPE WFS
    METADATA
	
	"wfs_title"    "Boundaries" 
	"wfs_service"           "WFS"
	"wfs_typename"          "Boundaries"
	"wfs_version"           "1.0.0"
	"wfs_request_method"    "GET"
	"wfs_connectiontimeout" "60"
	"wfs_maxfeatures"       "1"

    END

    TYPE LINE
    STATUS ON
    DATA "./base_info_boundaries"
    PROJECTION
      "init=nad83:401"
    END
    DUMP TRUE
    CLASS
      NAME "Boundaries"
      COLOR 80 80 80
      OUTLINECOLOR 80 80 80
    END
  END # End of Boundaries Layer
########################################

AND

2.

########################################
MAP


WEB

  METADATA
		"wfs_title"     "WMS Demo Server"  
  END
END

LAYER #  Start of Boundaries Layer

    NAME Boundaries 
    METADATA
	
	"wfs_title"    "Boundaries" 

    END

    TYPE LINE
    STATUS ON
    DATA "./base_info_boundaries"
    PROJECTION
      "init=nad83:401"
    END
    DUMP TRUE
    CLASS
      NAME "Boundaries"
      COLOR 80 80 80
      OUTLINECOLOR 80 80 80
    END
  END # End of Boundaries Layer
####################################

Both of these result in the same error and a zero string length in the
$szWFSConnection variable.  Oh and I'm using Mapserver 4.6 so the CONNECTION
is no longer used.  Any ideas?

Thanks,
Dave Findlay

Hi Dave,

is your layer a WMS or WFS connectiontype of layer?

If it is a WMS, the widget performs a DescribeLayer request to get the WFS
URL and the name of a typename, something like:

service=WMS&request=DescribeLayer&layers=blabla&version=1.1.1

So if your layer is WMS, can you check this request?

Best regards,
Bart

Hello all,

 

I'm having a bit of a problem with the sample_roi.  When I try and extract
wfs data I get :

 

"Invalid layer or none selected. Please ensure that the selected layer is a
WFS or WMS layer."

 

Now the layer I'm trying to extract seems to be configured fine in the
mapfile and if I do a straight:

 

http://localhost/cgi-bin/mapserv.exe?MAP=ex2.map
<http://localhost/cgi-bin/mapserv.exe?MAP=ex2.map&SERVICE=WFS&VERSION=1.0.0&
REQUEST=GetFeature&TYPENAME=Boundaries>
&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&TYPENAME=Boundaries

 

I get the complete gml in my browser.  I noticed that in the
ExtractWFSData.php file right around line 247 where it checks for a
connection the $szWFSConnection

actually has a length of zero.  I'm assuming this is the problem but I'm not
sure exactly how to fix it.  Any suggestions would be appreciated.

 

Cheers,

 

Dave Findlay
