Hi to all.
I did resolve (after a lot of research), my first problem:
I can get from geoserver, in a wps jython process, the layer's catalog
authorized to me.
The little program:
from geoserver.wps import process
from geoscript.geom import Geometry
from geoserver.catalog import Catalog, Workspace, Layer, Store
import org.springframework.security.core.context.SecurityContextHolder as
SecurityContextHolder
import org.geoserver.catalog as catalog
from org.geoserver.platform import GeoServerExtensions
@process(
title='Sample',
description='Sample',
inputs={'login': (str, 'login'),
'password': (str, 'password')},
outputs={'result': (str, 'login status')})
def run(login, password):
user=SecurityContextHolder.getContext().getAuthentication()
debug_file="/tmp/geoserver.log"
f=open(debug_file, "a")
f.write(str(user.getAuthorities().size()))
if user==None or user.getAuthorities().size()==0:
f.write("anonymous access\n")
else:
f.write(str(SecurityContextHolder.getContext().getAuthentication().getAuthorities()))
# Devuelve: [ROLE_AUTHENTICATED, ROLE_ADMINISTRATOR,
ROLE_CARTOGRAFIA_RO, ROLE_GROUP_ADMIN]
f.write("\n")
cat=Catalog()
try:
for workspace in cat.keys():
w=Workspace(workspace)
for datastore in w.keys():
d=Store(datastore)
for layer in d.keys():
l=Layer(layer)
cat1=GeoServerExtensions.bean('catalog')
store1=cat1.getStoreByName(workspace, datastore,
catalog.StoreInfo)
if store1 is None:
type=""
else:
ft=cat1.getFeatureTypeByDataStore(store1, layer)
type=str(ft.getFeatureType().getGeometryDescriptor().getType())
type=type.split(" ")[1]
f.write(type+"|"+workspace+":"+layer+"|"+l.title+"|"+"\n")
except Exception, e:
f.write(str(e)+"\n")
pass
But, now, I need:
a) wath is the vartype on outputs to return a string list?. I'm writting to
a local file, to do debug, but, I'm thinking to talk with a specific plugin
in qgis.
b) I'd like to do better code (I'm using catalog, workspace, store and
layer extensions, but, I'm thinking I can to access to the java api, like
I'm using springframework api). Any idea? All information I did obtain from
the source code.
c) I'd like to know my access level to each layer, to show to the user.
Can any help me?
Thanks a lot in advance
