python - Add a prefix to all Flask routes -

i have prefix want add every route. right add constant route @ every definition. there way automatically?

prefix = "/abc/123"  @app.route(prefix + "/") def index_page():   return "this website burritos"  @app.route(prefix + "/about") def about_page():   return "this website burritos" 

the answer depends on how serving application.

sub-mounted inside of wsgi container

assuming going run application inside of wsgi container (mod_wsgi, uwsgi, gunicorn, etc); need mount, @ prefix application sub-part of wsgi container (anything speaks wsgi do) , set application_root config value prefix:

app.config["application_root"] = "/abc/123"  @app.route("/") def index():     return "the url page {}".format(url_for("index"))  # return "the url page /abc/123/" 

setting application_root config value limit flask's session cookie url prefix. else automatically handled flask , werkzeug's excellent wsgi handling capabilities.

an example of sub-mounting app

if not sure first paragraph means, take @ example application flask mounted inside of it:

from flask import flask, url_for werkzeug.serving import run_simple werkzeug.wsgi import dispatchermiddleware  app = flask(__name__) app.config['application_root'] = '/abc/123'  @app.route('/') def index():     return 'the url page {}'.format(url_for('index'))  def simple(env, resp):     resp(b'200 ok', [(b'content-type', b'text/plain')])     return [b'hello wsgi world']  app.wsgi_app = dispatchermiddleware(simple, {'/abc/123': app.wsgi_app})  if __name__ == '__main__':     app.run('localhost', 5000) 

proxying requests app

if, on other hand, running flask application @ root of wsgi container , proxying requests (for example, if it's being fastcgi'd to, or if nginx proxy_pass-ing requests sub-endpoint stand-alone uwsgi / gevent server can either:

• use blueprint, miguel points out in his answer.
• or use dispatchermiddleware werkzeug (or prefixmiddleware su27's answer) sub-mount application in stand-alone wsgi server you're using. (see an example of sub-mounting app above code use).
