Even though Armin beat me to the punch with an accepted answer I thought I’d show an abbreviated example of how I implemented a regex matcher in Flask just in case anyone wants a working example of how this could be done.
from flask import Flask
from werkzeug.routing import BaseConverter
app = Flask(__name__)
class RegexConverter(BaseConverter):
def __init__(self, url_map, *items):
super(RegexConverter, self).__init__(url_map)
self.regex = items[0]
app.url_map.converters['regex'] = RegexConverter
@app.route('/<regex("[abcABC0-9]{4,6}"):uid>-<slug>/')
def example(uid, slug):
return "uid: %s, slug: %s" % (uid, slug)
if __name__ == '__main__':
app.run(debug=True, host="0.0.0.0", port=5000)
this URL should return with 200: http://localhost:5000/abc0-foo/
this URL should will return with 404: http://localhost:5000/abcd-foo/
