Getting a permanent redirect instead of executing the function on a URL with variables

[flixman]

In my code I have the following:

@bp.post('/refresh', defaults={'mode': 'app'})
@bp.post('/refresh/<mode>')
def refresh_expiring_jwts(mode):
    if mode not in ['app', 'web']:
        raise NotFound

I would expect that when pointing a request to /refresh/app, I'd get refresh_expiring_jwts executed. Instead, I am getting back a permanent redirect to "/refresh/". I have checked the urls map and there are two rules pointing to the same method, one for /refresh and another for /refresh/. At the same time, I see that in the definition of Map (line, 99) is set to True, with this description for the parameter:

    :param redirect_defaults: This will redirect to the default rule if it
                              wasn't visited that way. This helps creating
                              unique URLs.

This map is used in the initialization of MapAdapter, line 391, and then in then in line 628, for match():

            if self.map.redirect_defaults:
                redirect_url = self.get_default_redirect(rule, method, rv, query_args)
                if redirect_url is not None:
                    raise RequestRedirect(redirect_url)

So... I think I am missing something here? What am I doing wrong?

Environment:

• Python version: 3.11.5
• Flask version: 3.0.0

If you dont have the urls in use as is,I recommend using https://werkzeug.palletsprojects.com/en/3.0.x/routing/#werkzeug.routing.AnyConverter

As for the defaults redirect, at first glance it looks like different trailing slashes might cause confusion

Personally id recommend having distinct urls and not using a default with redirect

I had done that, finally. What I do not understand is: what is the reason/business case for implementing this with a redirect, that can be seen from outside the application, instead of just making a call to the method?
