ArcGIS REST provider uri().uri() has a double 'crs' attbute

rduivenvoorde commented 3 years ago

What is the bug or the crash?

Answering a question on matrix group (https://matrix.to/#/!iIpqCcxrWNnIYCMjjO:matrix.org/$1627713567115747aYUNR:matrix.org?via=libera.chat&via=matrix.org&via=osgeo.org) I see a double crs item in the provider uri which seems obsolete?

"crs='EPSG:26917' crs='EPSG:26917' url='https://services2.arcgis.com/XZg2efAbaieYAXmu/ArcGIS/rest/services/Hospitals/FeatureServer/0'"

Steps to reproduce the issue

To reproduce: 1) use the following service to create a ArcGIS Rest service in QGIS gui: https://services2.arcgis.com/XZg2efAbaieYAXmu/ArcGIS/rest/services/ 2) load the service 'Hospitals' in (a epsg:4326 world) project QGIS 3) make sure Hospitals is active and start the python console and paste:

uri = iface.mapCanvas().currentLayer().dataProvider().uri().uri()
print(uri)

It will show you the line above, with a double "crs='EPSG:26917'" part.

All is working fine, the uri can be used to create/load a valid layer:

layer = QgsVectorLayer(uri, "layername", "arcgisfeatureserver")
QgsProject.instance().addMapLayer(ayer)

but maybe this is a sign for something going wrong?

@rduivenvoorde I can't reproduce on master:

iface.activeLayer().dataProvider().uri()
#<QgsDataSourceUri:  crs='EPSG:26917' url='https://services2.arcgis.com/XZg2efAbaieYAXmu/ArcGIS/rest/services/Hospitals/FeatureServer/0'>
iface.activeLayer().dataProvider().uri().uri()
#" crs='EPSG:26917' url='https://services2.arcgis.com/XZg2efAbaieYAXmu/ArcGIS/rest/services/Hospitals/FeatureServer/0'"

can you try with a fresh build?

rduivenvoorde commented 3 years ago

@lbartoletti just did, with fresh build:

uri = iface.mapCanvas().currentLayer().dataProvider().uri().uri()
print(uri)
 crs='EPSG:26917' crs='EPSG:26917' url='https://services2.arcgis.com/XZg2efAbaieYAXmu/ArcGIS/rest/services/Hospitals/FeatureServer/0'
