Altering AWS environment custom variable with PyQGIS

Question

I was able to create a script which imports into QGIS .vrt files from a private bucket in Amazon Web Services S3.

But I had this one-time task to manually set the environment custom variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY.

What I did was: Settings (1) -> Options (2) -> System (3) --> Environment (use custom variables) (4) --> Variable (5) --> Values (6)

Is there a way to do this with PyQGIS?

I am using QGIS 3.34.5

Answer 1

You could just use os.environ at the start of your script:

import os
os.environ["AWS_ACCESS_KEY_ID"] = "Some value"
os.environ["AWS_SECRET_ACCESS_KEY"] = "Another value"
