In the current implementation, the input, output, doc, and auth_required are standalone decorators, which makes it hard to config the internal behavior since it can't access the config object. I'm thinking of changing them to methods of APIFlask class:

from apiflask import APIFlask


app = APIFlask(__name__)

@app.get('/')
@app.input(PetInSchema)
@app.output(PetOutSchema)
def hello(data):
    return 'Hello'

With this change, we can easily implement:

• More support for pagination
• Skip all validation for input with a global configuration variable
• Support external authentication libraries

The initial plan:

• Add these mirror methods to APIFlask and APIBlueprint in 0.12.0
• Add warning for old standalone decorators in 1.0
• Remove the standalone decorators in 2.0
