Hi, I tried also with QGIS 3.21 nightly and it did not work any better for me. I do not see the Options panel as in the screenshot by Jorge. Somehow it feels like my QGIS does not manage to make the http connection. I am behind a proxy server but I can reach WMS and WMTS services through the proxy.

Hi, I have tried, but that does not work for me with QGIS 3.18. Opening the URL (with or without double quotes) as a file gives me just this: Invalid Data Source: https://api.digitransit.fi/routing/v1/routers/hsl/isochrone?fromPlace=60.168,24.938&mode=WALK,TRANSIT&date=2019-11-01&time=08:00:00&maxWalkDistance=500&cutoffSec=1800&cutoffSec=3600 is not a valid or recognized data source. -Jukka- Lähettäjä: Even Rouault <even.roua...@spatialys.com<mailto:even.roua...@spatialys.com>> Lähetetty: tiistai 21. syyskuuta 2021 13.56 Vastaanottaja: Rahkonen Jukka (MML) <jukka.rahko...@maanmittauslaitos.fi<mailto:jukka.rahko...@maanmittauslaitos.fi>>; qgis-user@lists.osgeo.org<mailto:qgis-user@lists.osgeo.org> Aihe: Re: [Qgis-user] How make reading from protocol to use /vsicurl_streaming/ instead of /vsicurl/? Jukka, Somewhat counter-intuitively, you can use "https://api.digitransit.fi/routing/v1/routers/hsl/isochrone?fromPlace=60.168,24.938&mode=WALK,TRANSIT&date=2019-11-01&time=08:00:00&maxWalkDistance=500&cutoffSec=1800&cutoffSec=3600" as a filename when using the File source type. This is due to GeoJSON driver having a particular logic when passed a http[s]:// filename to ingest it fully in memory.

With this service /vsicurl/ does not work but /vsicurl_streaming/ works. It there any way to force QGIS to use the streaming mode? The debugging tools do not seem to log the network traffic from the "read from protocol" requests. Is that a right observation? -Jukka Rahkonen- _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org<mailto:Qgis-user@lists.osgeo.org> List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user -- http://www.spatialys.com My software is free, but my time generally not.
