Using Flask with Google App Engine Dev Server, swagger ui not found?

Question

I am developing a website using Flask and Flask Restplus. I tried to use Google App Engine to deploy the app, however when I run dev_appserver.py on my computer, all the swagger-ui files cannot be found. I have no ideas why this happens? Can anyone tell me how to solve this?

Here is the example logs 404 for the resource:

You need to put swaggerui inside your project. I suggest making a libs directory at the root of your project (same level as app.yaml).

Then, use GAE's vendoring method. To use vendoring, create (or modify) appengine_config.py in the root of your project, as follows:

from google.appengine.ext import vendor

# Add 3rd party libraries in the "libs" folder.
vendor.add('libs')
