I'm creating a simple server to serve images from a Google Cloud Storage
bucket. It will serve images to a mobile app. I'm new to Google Cloud
Storage and a python3 Appengine server, I've been running a py2.7 server
for years.
I am able to create a cloud storage client and query items, that's working.
It seems wasteful to download the images to the Appengine server to in-turn
send those to my app. Ideally I can provide my app a url to pull from
storage directly. I can do this if I make the bucket publicly accessible
but ideally I don't have to do that.
>From what I can tell there are a couple of options
1) Use *from google.appengine.api import images *which has a *get_serving_url
*function which sounds like it's the right thing. But when I try using it
I'm getting and error:
*AssertionError: No api proxy found for service "image"*
2) Also looks like there's an option to use *from google.appengine.api
import blobstore *and use* blobstore.create_gs_key('/gs' + filename) *but
I get a similar error:
*AssertionError: No api proxy found for service "blobstore"*
3) lastly it looks like there's a way to generate a url that times out using*
blob.generate_signed_url().
*When I use that I get:
*You need a private key to sign credentials.the credentials you are
currently using <class
'google.auth.compute_engine.credentials.Credentials'> just contains a
token. see
https://googleapis.dev/python/google-api-core/latest/auth.html#setting-up-a-service-account
for more details.*
So far a lot of dead ends. Reading about the* no api proxy *most people are
pointing to users who are not running within the AppEngine environment ..
but I am and I think it may be because these api's were originally built
for the py2 version of Appengine and I'm attempting to use them in py3? I
suppose I could change my app to a py2 app, but that seems like a dead end
long term.
Thanks for any pointers!
