Web Application

`connect.eaas.core.decorators.web_app`

This function returns a decorator that converts the decorated into a class-based view for the provided router.

Any methods of the decorated class that are decorated as endpoints using the router provided to this function will become endpoints in the router. The first positional argument to the methods (typically self) will be populated with an instance created using FastAPI's dependency-injection.

For more detail, review the documentation at https://fastapi-utils.davidmontague.xyz/user-guide/class-based-views/#the-cbv-decorator

This decorator is required to be used if you want to declare any endpoint.

Usage:

from connect.eaas.core.decorators import (
    router, web_app,
)
from connect.eaas.core.extension import WebApplicationBase


@web_app(router)
class MyWebApp(WebApplicationBase):
    pass

`connect.eaas.core.decorators.unauthorized()`

Mark an endpoint of a Web Application as not subject to the Connect authentication.

Usage:

from connect.eaas.core.decorators import unauthorized, router, web_app

class MyWebApp(WebApplicationBase):

    @unauthorized()
    @router.get('/my_endpoint')
    def my_endpoint(self):
        pass

Note

In releases prior to 27, unauthenticated endpoints required authorization by CloudBlue. Although this feature is now enabled by default, if your extension was created using a version earlier than release 27, you must still contact CloudBlue support to enable unauthenticated endpoints for your extension.
