    @staticmethod
    @webob.dec.wsgify
    def _dispatch(req):
        match = req.environ['wsgiorg.routing_args'][1]

        if not match:
            return webob.exc.HTTPNotFound()

        app = match['controller']
        return app



app = Router()
httpd = make_server('localhost', 8282, app)
httpd.serve_forever()

 

  22行：创建一个mapper

  23行：#注册一个路由

  28行：创建一个RoutesMiddleware对象，匹配路由，修改环境变量后，调用self._dispatch
