QGIS Desktop Main Window

How can I connect to Geonode?

Open QGIS Desktop and go to Layer Menu > Data Source Manager. At the bottom of Data Source Manager, you can see a tab with the name and an icon related to Geonode. This is because Geonode is recognized as a data source inside QGIS.

Note

It’s possible as well load Geonode instances from an existence file this is useful to share between users or to backup existence connections.

To add a new Geonode instance, in the Geonode tab selected click on New and you will see the following dialog:

In the dialog Fill the name as you like and in the URL put the link of the Geonode instance. It’s possible edit some WFS and WMS options to optimize the connection. If everything is ok you will receive the following successful connection dialog:

After the successful dialog it’s now possible to load all layers of the Geonode instance clicking on Connect button. You can see both WMS and WFS connections of the Geonode and you can load to QGIS Desktop.

Example of Geonode layer

Warning

This procedure only work with public layers. If the layers are for private use is necessary to do the standard qgis add remote WMS/WFS layers (through Data Source Manager) along with basic auth method and specific endpoints.

Connect to Private layers by using OAuth2

GeoNode OAuth2 Client App Setup

Login to GeoNode as a superuser

../../../_images/geonode_oauth2_001.png

Browse to http://<geonode>/o/applications/

../../../_images/geonode_oauth2_002.png

Create a new specific app or, better, edit the existing one (“GeoServer”) based on OAuth2 Authorization Code Grant Type

Click on “Edit” and add the Redirect URI http://127.0.0.1:7070/qgis-client as shown below

Note

This is an example. The port and path of the URI can be customized. They must be the same on both GeoNode and QGis Client as shown later.

Also you will need the Client ID and Client Secret keys later when configuring QGis.

Configure QGis Desktop Client OAuth2 Authentication

Open the QGis Desktop Client and add a new OWS remote Layer configuration

../../../_images/geonode_oauth2_005.png

Create a new service connection

../../../_images/geonode_oauth2_006.png

Provide the connection details

Note

It is Important that the URL ends with /gs/ows

When finished click on “+” in order to add a new auth configuration

../../../_images/geonode_oauth2_007.png

Provide the needed information as shown below:

  • Name: any descriptive string
  • Type: OAuth2 authentication
  • Grant Flow: Authorization Code
  • Request URL: must end with /o/authorize/
  • Token URL and Refresh URL: must end with /o/token/
  • Redirect URL: must match with the one defined on GeoNode above
  • Client ID and Client Secret: must match with the one defined on GeoNode above
  • Scopes: openid write
  • Enable the persistent Token Session via Headers

Save and click on “Connect”. QGis will redirect you on a browser page asking to GeoNode to authenticate. Approve the Claims and go back to QGis.
