A simple way would be applying regular expression tests on the ``PATH_INFO`` and calling registered callback functions that return the value then. This module implements a much more powerful system than simple regular expression matching because it can also convert values in the URLs and build URLs. Here a simple example that creates a URL map for an application with two subdomains (www and kb) and some URL rules: .. code-block:: python m = Map([ # Static URLs Rule('/', endpoint='static/index'), Rule('/about', endpoint='static/about'), Rule('/help', endpoint='static/help'), # Knowledge Base Subdomain('kb', [ Rule('/', endpoint='kb/index'), Rule('/browse/', endpoint='kb/browse'), Rule('/browse/<int:id>/', endpoint='kb/browse'), Rule('/browse/<int:id>/<int:page>', endpoint='kb/browse') ]) ], default_subdomain='www') If the application doesn't use subdomains it's perfectly fine to not set the default subdomain and not use the `Subdomain` rule factory. The endpoint in the rules can be anything, for example import paths or unique identifiers. The WSGI application can use those endpoints to get the handler for that URL. It doesn't have to be a string at all but it's recommended. Now it's possible to create a URL adapter for one of the subdomains and build URLs: .. code-block:: python c = m.bind('example.com') c.build("kb/browse", dict(id=42)) 'http://kb.example.com/browse/42/' c.build("kb/browse", dict()) 'http://kb.example.com/browse/' c.build("kb/browse", dict(id=42, page=3)) 'http://kb.example.com/browse/42/3' c.build("static/about") '/about' c.build("static/index", force_external=True) 'http://www.example.com/' c = m.bind('example.com', subdomain='kb') c.build("static/about") 'http://www.example.com/about' The first argument to bind is the server name *without* the subdomain. Per default it will assume that the script is mounted on the root, but often that's not the case so you can provide the real mount point as second argument: .. code-block:: python c = m.bind('example.com', '/applications/example') The third argument can be the subdomain, if not given the default subdomain is used. For more details about binding have a look at the documentation of the `MapAdapter`. And here is how you can match URLs: .. code-block:: python c = m.bind('example.com') c.match("/") ('static/index', {}) c.match("/about") ('static/about', {}) c = m.bind('example.com', '/', 'kb') c.match("/") ('kb/index', {}) c.match("/browse/42/23") ('kb/browse', {'id': 42, 'page': 23}) If matching fails you get a ``NotFound`` exception, if the rule thinks it's a good idea to redirect (for example because the URL was defined to have a slash at the end but the request was missing that slash) it will raise a ``RequestRedirect`` exception. Both are subclasses of ``HTTPException`` so you can use those errors as responses in the application. If matching succeeded but the URL rule was incompatible to the given method (for example there were only rules for ``GET`` and ``HEAD`` but routing tried to match a ``POST`` request) a ``MethodNotAllowed`` exception is raised. � N)�pformat)�Template)�Lock)�CodeType� )� _encode_idna)� _get_environ)� _to_bytes)�_to_str)�_wsgi_decoding_dance)� ImmutableDict)� MultiDict)�BadHost)� BadRequest)� HTTPException)�MethodNotAllowed)�NotFound)�_fast_url_quote)� url_encode)�url_join)� url_quote)� url_unquote)�cached_property)�redirect)�get_host)�WSGIApplication)�WSGIEnvironment)�Request)�Responseao (?P<static>[^<]*) # static rule data < (?: (?P<converter>[a-zA-Z_][a-zA-Z0-9_]*) # converter name (?:\((?P<args>.*?)\))? # converter arguments \: # variable delimiter )?

There are some options for `Rule` that change the way it behaves and are passed to the `Rule` constructor. Note that besides the rule-string all arguments *must* be keyword arguments in order to not break the application on Werkzeug upgrades. `string` Rule strings basically are just normal URL paths with placeholders in the format ``<converter(arguments):name>`` where the converter and the arguments are optional. If no converter is defined the `default` converter is used which means `string` in the normal configuration. URL rules that end with a slash are branch URLs, others are leaves. If you have `strict_slashes` enabled (which is the default), all branch URLs that are matched without a trailing slash will trigger a redirect to the same URL with the missing slash appended. The converters are defined on the `Map`. `endpoint` The endpoint for this rule. This can be anything. A reference to a function, a string, a number etc. The preferred way is using a string because the endpoint is used for URL generation. `defaults` An optional dict with defaults for other rules with the same endpoint. This is a bit tricky but useful if you want to have unique URLs:: url_map = Map([ Rule('/all/', defaults={'page': 1}, endpoint='all_entries'), Rule('/all/page/<int:page>', endpoint='all_entries') ]) If a user now visits ``http://example.com/all/page/1`` he will be redirected to ``http://example.com/all/``. If `redirect_defaults` is disabled on the `Map` instance this will only affect the URL generation. `subdomain` The subdomain rule string for this rule. If not specified the rule only matches for the `default_subdomain` of the map. If the map is not bound to a subdomain this feature is disabled. Can be useful if you want to have user profiles on different subdomains and all subdomains are forwarded to your application:: url_map = Map([ Rule('/', subdomain='<username>', endpoint='user/homepage'), Rule('/stats', subdomain='<username>', endpoint='user/stats') ]) `methods` A sequence of http methods this rule applies to. If not specified, all methods are allowed. For example this can be useful if you want different endpoints for `POST` and `GET`. If methods are defined and the path matches but the method matched against is not in this list or in the list of another rule for that path the error raised is of the type `MethodNotAllowed` rather than `NotFound`. If `GET` is present in the list of methods and `HEAD` is not, `HEAD` is added automatically. `strict_slashes` Override the `Map` setting for `strict_slashes` only for this rule. If not specified the `Map` setting is used. `merge_slashes` Override :attr:`Map.merge_slashes` for this rule. `build_only` Set this to True and the rule will never match but will create a URL that can be build. This is useful if you have resources on a subdomain or folder that are not handled by the WSGI application (like static data) `redirect_to` If given this must be either a string or callable. In case of a callable it's called with the url adapter that triggered the match and the values of the URL as keyword arguments and has to return the target for the redirect, otherwise it has to be a string with placeholders in rule syntax:: def foo_with_slug(adapter, id): # ask the database for the slug for the old id. this of # course has nothing to do with werkzeug. return f'foo/{Foo.get_slug_for_id(id)}' url_map = Map([ Rule('/foo/<slug>', endpoint='foo'), Rule('/some/old/url/<slug>', redirect_to='foo/<slug>'), Rule('/other/old/url/<int:id>', redirect_to=foo_with_slug) ]) When the rule is matched the routing system will raise a `RequestRedirect` exception with the target for the redirect. Keep in mind that the URL will be joined against the URL root of the script so don't use a leading slash on the target URL unless you really mean root of that domain. `alias` If enabled this rule serves as an alias for another rule with the same endpoint and arguments. `host` If provided and the URL map has host matching enabled this can be used to provide a match rule for the whole host. This also means that the subdomain feature is disabled. `websocket` If ``True``, this rule is only matches for WebSocket (``ws://``, ``wss://``) requests. By default, rules will only match for HTTP requests. .. versionadded:: 1.0 Added ``websocket``. .. versionadded:: 1.0 Added ``merge_slashes``. .. versionadded:: 0.7 Added ``alias`` and ``host``. .. versionchanged:: 0.6.1 ``HEAD`` is added to ``methods`` if ``GET`` is present.

This helps creating unique URLs. :param converters: A dict of converters that adds additional converters to the list of converters.

Note that `script_name` will default to ``'/'`` if not further specified or `None`. The `server_name` at least is a requirement because the HTTP RFC requires absolute URLs for redirects and so all redirect exceptions raised by Werkzeug will contain the full canonical URL. If no path_info is passed to :meth:`match` it will use the default path info passed to bind. While this doesn't really make sense for manual bind calls, it's useful if you bind a map to a WSGI environment which already contains the path info. `subdomain` will default to the `default_subdomain` for this map if no defined. If there is no `default_subdomain` you cannot use the subdomain feature. .. versionchanged:: 1.0 If ``url_scheme`` is ``ws`` or ``wss``, only WebSocket rules will match. .. versionchanged:: 0.15 ``path_info`` defaults to ``'/'`` if ``None``. .. versionchanged:: 0.8 ``query_args`` can be a string. .. versionchanged:: 0.7 Added ``query_args``.

Note that because of limitations in the protocol there is no way to get the current subdomain and real `server_name` from the environment. If you don't provide it, Werkzeug will use `SERVER_NAME` and `SERVER_PORT` (or `HTTP_HOST` if provided) as used `server_name` with disabled subdomain feature. If `subdomain` is `None` but an environment and a server name is provided it will calculate the current subdomain automatically. Example: `server_name` is ``'example.com'`` and the `SERVER_NAME` in the wsgi `environ` is ``'staging.dev.example.com'`` the calculated subdomain will be ``'staging.dev'``. If the object passed as environ has an environ attribute, the value of this attribute is used instead. This allows you to pass request objects. Additionally `PATH_INFO` added as a default of the :class:`MapAdapter` so that you don't have to pass the path info to the match method. .. versionchanged:: 1.0.0 If the passed server name specifies port 443, it will match if the incoming scheme is ``https`` without a port. .. versionchanged:: 1.0.0 A warning is shown when the passed server name does not match the incoming WSGI server name. .. versionchanged:: 0.8 This will no longer raise a ValueError when an unexpected server name was passed. .. versionchanged:: 0.5 previously this method accepted a bogus `calculate_subdomain` parameter that did not have any effect. It was removed because of that. :param environ: a WSGI environment. :param server_name: an optional server name hint (see above). :param subdomain: optionally the current subdomain (see above). zwsgi.url_schemec s s | ]}|� � d kV qdS )�upgradeN)�strip�r� �vr, r, r- � <genexpr>~ s �z&Map.bind_to_environ.<locals>.<genexpr>ZHTTP_CONNECTIONr� r0 Z HTTP_UPGRADEr� �https�wss�wsN> r� rt z:80���> r� r� z:443���r� zCurrent server name z& doesn't match configured server name � )� stacklevelz <invalid>)r1 r$ c s" � � | �}|d ur t|�j�S d S rV )�getr r� )r1 �val��envrY r, r- �_get_wsgi_string� s z-Map.bind_to_environ.<locals>._get_wsgi_stringZ SCRIPT_NAMEZ PATH_INFOZ QUERY_STRING�REQUEST_METHOD)ry )r r rz re r� r r� r� rB �warnings�warnr� �filterr* ra rb r� r� )rY r] ru r� Zwsgi_server_name�schemer} Zcur_server_nameZreal_server_name�offsetr� rv rg ry r, r� r- �bind_to_environL sT / � �� �zMap.bind_to_environru c C s� | j s dS | j�^ | j s(W d � dS | jjdd� d� | j�� D ]}|jdd� d� qDd| _ W d � n1 st0 Y dS )zzCalled before matching and building to keep the compiled rules in the correct order after things changed.

It should look up the view function, call it, and return a response object or WSGI application. http exceptions are not caught by default so that applications can display nicer error messages by just catching them by hand. If you want to stick with the default error messages you can pass it ``catch_http_exceptions=True`` and it will catch the http exceptions. Here a small example for the dispatch usage:: from werkzeug.wrappers import Request, Response from werkzeug.wsgi import responder from werkzeug.routing import Map, Rule def on_index(request): return Response('Hello from the index') url_map = Map([Rule('/', endpoint='index')]) views = {'index': on_index} @responder def application(environ, start_response): request = Request(environ) urls = url_map.bind_to_environ(environ) return urls.dispatch(lambda e, v: views[e](request, **v), catch_http_exceptions=True) Keep in mind that this method might return exception objects, too, so use :class:`Response.force_type` to get a response object. :param view_func: a function that is called with the endpoint as first argument and the value dict as second. Has to dispatch to the actual view function with this information. (see above) :param path_info: the path info to use for matching. Overrides the path info specified on binding. :param method: the HTTP method used for matching. Overrides the method specified on binding. :param catch_http_exceptions: set to `True` to catch any of the werkzeug :class:`HTTPException`\s.

The following things can then happen: - you receive a `NotFound` exception that indicates that no URL is matching. A `NotFound` exception is also a WSGI application you can call to get a default page not found page (happens to be the same object as `werkzeug.exceptions.NotFound`) - you receive a `MethodNotAllowed` exception that indicates that there is a match for this URL but not for the current request method. This is useful for RESTful applications. - you receive a `RequestRedirect` exception with a `new_url` attribute. This exception is used to notify you about a request Werkzeug requests from your WSGI application. This is for example the case if you request ``/foo`` although the correct URL is ``/foo/`` You can use the `RequestRedirect` instance as response-like object similar to all other subclasses of `HTTPException`. - you receive a ``WebsocketMismatch`` exception if the only match is a WebSocket rule but the bind is an HTTP request, or if the match is an HTTP rule but the bind is a WebSocket request. - you get a tuple in the form ``(endpoint, arguments)`` if there is a match (unless `return_rule` is True, in which case you get a tuple in the form ``(rule, arguments)``) If the path info is not passed to the match method the default path info of the map is used (defaults to the root URL if not defined explicitly). All of the exceptions raised are subclasses of `HTTPException` so they can be used as WSGI responses. They will all render generic error or redirect pages. Here is a small example for matching: >>> m = Map([ ... Rule('/', endpoint='index'), ... Rule('/downloads/', endpoint='downloads/index'), ... Rule('/downloads/<int:id>', endpoint='downloads/show') ... ]) >>> urls = m.bind("example.com", "/") >>> urls.match("/", "GET") ('index', {}) >>> urls.match("/downloads/42") ('downloads/show', {'id': 42}) And here is what happens on redirect and missing URLs: >>> urls.match("/downloads") Traceback (most recent call last): ... RequestRedirect: http://example.com/downloads/ >>> urls.match("/missing") Traceback (most recent call last): ... NotFound: 404 Not Found :param path_info: the path info to use for matching. Overrides the path info specified on binding. :param method: the HTTP method used for matching. Overrides the method specified on binding. :param return_rule: return the rule that matched instead of just the endpoint (defaults to `False`). :param query_args: optional query arguments that are used for automatic redirects as string or dictionary. It's currently not possible to use the query arguments for URL matching. :param websocket: Match WebSocket instead of HTTP requests. A websocket request has a ``ws`` or ``wss`` :attr:`url_scheme`. This overrides that detection. .. versionadded:: 1.0 Added ``websocket``. .. versionchanged:: 0.8 ``query_args`` can be a string. .. versionadded:: 0.7 Added ``query_args``. .. versionadded:: 0.6 Added ``return_rule``.

Instead of `match` you call `build` and pass it the endpoint and a dict of arguments for the placeholders. The `build` function also accepts an argument called `force_external` which, if you set it to `True` will force external URLs. Per default external URLs (include the server name) will only be used if the target URL is on a different subdomain. >>> m = Map([ ... Rule('/', endpoint='index'), ... Rule('/downloads/', endpoint='downloads/index'), ... Rule('/downloads/<int:id>', endpoint='downloads/show') ... ]) >>> urls = m.bind("example.com", "/") >>> urls.build("index", {}) '/' >>> urls.build("downloads/show", {'id': 42}) '/downloads/42' >>> urls.build("downloads/show", {'id': 42}, force_external=True) 'http://example.com/downloads/42' Because URLs cannot contain non ASCII data you will always get bytes back. Non ASCII characters are urlencoded with the charset defined on the map instance. Additional values are converted to strings and appended to the URL as URL querystring parameters: >>> urls.build("index", {'q': 'My Searchstring'}) '/?q=My+Searchstring' When processing those additional values, lists are furthermore interpreted as multiple values (as per :py:class:`werkzeug.datastructures.MultiDict`): >>> urls.build("index", {'q': ['a', 'b', 'c']}) '/?q=a&q=b&q=c' Passing a ``MultiDict`` will also add multiple values: >>> urls.build("index", MultiDict((('p', 'z'), ('q', 'a'), ('q', 'b')))) '/?p=z&q=a&q=b' If a rule does not exist when building a `BuildError` exception is raised. The build method accepts an argument called `method` which allows you to specify the method you want to have an URL built for if you have different methods for the same endpoint specified. :param endpoint: the endpoint of the URL to build. :param values: the values for the URL to build. Unhandled values are appended to the URL as query parameters. :param method: the HTTP method for the rule if there are different URLs for different methods on the same endpoint. :param force_external: enforce full canonical external URLs. If the URL scheme is not provided, this will generate a protocol-relative URL. :param append_unknown: unknown parameters are appended to the generated URL as query string argument. Disable this if you want the builder to ignore those. :param url_scheme: Scheme to use in place of the bound :attr:`url_scheme`. .. versionchanged:: 2.0 Added the ``url_scheme`` parameter. .. versionadded:: 0.6 Added the ``append_unknown`` parameter.
