If you integrate your API with an OAuth2 provider, you will be able to authenticate and come back to the API docs with the acquired credentials. And interact with it using the real OAuth2 authentication.

Swagger UI will handle it behind the scenes for you, but it needs this "redirect" helper.

Now, to be able to test that everything works, create a *path operation*:

All the dependencies we have seen are a fixed function or class.

But there could be cases where you want to be able to set parameters on the dependency, without having to declare many different functions or classes.

Let's imagine that we want to have a dependency that checks if the query parameter `q` contains some fixed content.

But we want to be able to parameterize that fixed content.

With `passlib`, you could even configure it to be able to read passwords created by **Django**, a **Flask** security plug-in or many others.

So, you would be able to, for example, share the same data from a Django application in a database with a FastAPI application. Or gradually migrate a Django application using the same database.

And your users would be able to login from your Django app or from your **FastAPI** app, at the same time.

When configured, MinIO sends request and credential details for every API call to an external HTTP(S) endpoint and expects an allow/deny response. MinIO is thus able to delegate access management to an external system, and users are able to use a custom solution instead of S3 standard IAM policies.

The .mvn directory is needed to be able to use the ${maven.multiModuleProjectDirectory} property....
