I am a beginner with Flask and python. I want to create a handler function for paths that start with "/favicon". For example the following should be handled:
The following should not be handled:
If Flask supporeted wildcards, it would be "/favicon*"
EDIT: I don't need support for regular expressions.
How can I do this?
I would do a catch-all
url and then, try to use a wildcard
with it from inside the view:
@app.route('/<path:text>', methods=['GET', 'POST'])
def all_routes(text):
if text.startswith('favicon'):
#do stuff
else:
return redirect(url_for('404_error'))
you can use string
too:
@app.route('/<string:text>', methods=['GET'])
but using string
wouldn't catch /
strings. so if string is used, url's
containing something like favicon/buzz
wouldn't be cached by it, path
in the other hand would catch /
's too. so you should go with first option.
you can look at routing documentation in flask site. and you should
create a better conditional than if x in Y
because it will fail if you were passed something like /thingfavicon
