flask_nofloc.add_nofloc_header(view_function)¶

Adds the Permission-Policy header to a result from a view function.

This is supposed to be used as a decorator and should come after the flask.Flask.route() or flask.Blueprint.route() decorator:

@app.route('/nofloc')
@add_nofloc_header
def nofloc_route():
    return 'response'

Parameters: view_function (callable()) – A view function, see Blueprints and Views.

flask_nofloc._add_nofloc_header(response)¶

Adds the Permission-Policy header to a Response.

This is an internal function and is called by add_nofloc_header() and registered as an flask.Flask.after_request() hook in NoFLoC.init_app() .

The function adds the Permission-Policy header with a value of interest-cohort=() unless it is already present.
