Routes是采用Python实现的Rails的URL映射控制. Routes makes it easy to create pretty and concise URL's that are RESTful with little effort.
Speedy and dynamic URL generation means you get a URL with minimal cruft (no big dangling query args). Shortcut features like Named Routes cut down on repetitive typing.
Current features:
Named Routes
Sophisticated Route lookup and URL generation
Wildcard path's before and after static parts
Groupings syntax to allow flexible URL's to accommodate almost any need
Sub-domain support built-in
Conditional matching based on domain, cookies, HTTP method (RESTful), and more
Easily extensible utilizing custom condition functions and route generation functions
Extensive unit tests
