        self._router = routes.middleware.RoutesMiddleware(self._dispatch, self._mapper)

    @webob.dec.wsgify

    @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
