I understand you're trying to do it with Python, I know what PyQGIS is. The it in question though is as I have described, that is what you will need to do programmatically. If your urlWithParams = "url=http://www.geoportaligm.gob.ec/50k/wms&format=image/png&layers=igm:acequia_l&styles=&crs=EPSG:32717" is meant to be the URL that generates the contextual legend then you will need replace that with an appropriate GetLegendGraphic request. You will need to split the contextual and noncontextual components, as the contextual part changes as your zoom/move the map.

| Mar 4, 2018 at 4:07 | comment | added | George | Thanks for taking your time and give such a nice explanation. Nevertheless I am looking for doing it by means of python code. If you try to run the code provided within the python console, you will find that this method loads the data but there is no legend. Could you give me a hand with that? | |
