Secured WMS Question

[Sven Axt]

Hi All,

I would like to access a secured WMS with GeoScript Groovy to generate mbtiles. While unsecured services work fine, there is a problem with a secured one: I see no possibility to set the credentials.

WMS wms = new WMS("https://secured.org/geoserver/test/wms?service=wms&version=1.1.1&request=GetCapabilities")
def layer = new WMSLayer(wms, ["test"])
def minZoom = 9
def maxZoom = 10

Projection latLonProj = new Projection("EPSG:4326")
Projection mercatorProj = new Projection("EPSG:3857")
Bounds latLonBounds = wms.getLayer('test').latLonBounds
Bounds mercatorBounds = latLonBounds.reproject(mercatorProj)

File mbfile = new File("test.mbtiles")
MBTiles mbtiles = new MBTiles(mbfile, "TEST", "test")

TileRenderer renderer = new ImageTileRenderer(mbtiles, layer)
TileSubGridGenerator generator = new TileSubGridGenerator()
generator.generate(mbtiles, renderer, minZoom, maxZoom, mercatorBounds)
mbtiles.close()

The constructor of the WMS class throws a GetCapabilities request, which is of course answered with a "401" without credentials.
The WebMapServer in the WMS class is private, so we can not inject one with credentials.

Does somebody has any idea?

Regards
Sven

Hi Sven,

I some some ideas,  but I'll disclose that I haven't actually tried it.  ;-)

So,  looking at the source for geoscript.layer.WMS,  It is a friendly wrapper

around org.geotools.data.wms.WebMapServer.   If you look at the constructors 

listed in the javadoc,  you'll notice another constructor that isn't in the Groovy

wrapper that takes an additional parameter of type org.geotools.data.ows.HTTPClient.

I think that's where you'll need to pass in the credentials.

I betcha you can subclass GeoScript's WMS and add a constructor to pass that info in

and call the other constructor for WebMapServer.   I've found some sample code that shows

how to create a WebMapServer w/credentials via google:

http://www.programcreek.com/java-api-examples/index.php?api=org.geotools.data.wms.WebMapServer

(check out Example 10)

Hopefully,  that will kinda get the ball rolling,  lemme know.

Take care,

--scottie

Thank you Scottie!  

Sven, can you test this?  If it works, we could add a constructor with user and password parameters.

Cheers,

Jared

Hi Jared and  Scott,

 

yes, sure. I will provide feedback.

 

Regards

Sven
