I'm aware of how to use the Python API to authenticate to a GIS and then create a FeatureLayer from a feature service to query or extract data from.
However, I can't seem to figure out how to do the same when there is no underlying Portal.
The feature service in question is restricted, but I am able to login and traverse the REST endpoints from my browser. Similarly, I can (using Python) generate a token from the Server's generateToken endpoint. However, since the server is not federated, I am not able to use the Python API to get access to the underlying feature services:
For my example: say my REST endpoints are at: https://myserver.domain.com/restricted/rest/services
gis = GIS("https://myserver.domain.com/restricted", username=username, password=password) - generates an error
fl = arcgis.features.FeatureLayer("https://myserver.domain.com/restricted/rest/services/myservice/0").query() - also generates an error.
I have tried generating a token and then passing it in to both the Feature layer or the GIS and nothing seems to work. Is there any workaround here I'm missing?
Nevermind - just realized there is a arcgis.gis.server module that solves my issue. Figured it out.
gis = arcgis.gis.server.Server("https://myserver.domain.com/restricted/admin", username=username, password=password)
fl = arcgis.features.FeatureLayer(featurelayerurl, gis=gis).query()
