Yes sorry about this - Eric reported this same problem this week. bioblend is not using API endpoints to download datasets and this is a problem for proxies with REMOTE_USER configured since most such proxies are only configured to allow through requests on /api and this is definitely not the route bioblend is using. I fixed a problem earlier this week and know at least bioblend is consistently using the wrong URL. https://github.com/afgane/bioblend/commit/01c20b18df68f00c016ef28e9d8bac2043... I added an API endpoint for downloading datasets from Galaxy in https://bitbucket.org/galaxy/galaxy-central/pull-request/131/implement-equiv... and I used it for some stuff - but it seems it has never made it into bioblend. I will try to find some time to update bioblend to use this - very sorry. -John On Thu, Aug 21, 2014 at 5:55 PM, Brad Zeitner <BZeitner@benaroyaresearch.org> wrote:

I have a python script that I use to download the qc data generated in one of the steps in a workflow. It used to work on a previous install of galaxy – but we’ve gone through and updated our Galaxy install so that it’s now running on a new file system - and when I try and use the bioblend api to download the dataset the request for the file gets redirected to the login page.

The call to download it is - dm = gi.datasets.download_dataset(qcf.get("id"), outfile, False ) Where qcf is the history step This calls the following url:/datasets/4fa2da3cf0e735a4/display?to_ext=html

If I visit the url in a browser that’s not in a session, it behaves the same way – but works correctly when I am logged in. How can I access this using the api key? When I add the parameters key=${myKey} it still fails.

Thanks, -Brad Zeitner
