高级Webapp2路由(Advanced Webapp2 Routing)

 在旧式webapp中，基于app.yaml的路由允许您检查正则表达式，如果匹配，则由处理程序处理请求，该处理程序的名称基于找到的模式。 例如，如果匹配的模式是“user”，则\ 1_handler.py会调度到user_handler.py。 
 
 有没有办法用webapp2.Route做同样的事情？ 惰性处理程序或method_handler参数可以基于模板中匹配的模式吗？ 

In old school webapp, app.yaml based routing allowed you to check for regular expressions and if matched, process a request by a handler whose name is based on the found pattern. For example \1_handler.py would dispatch to user_handler.py if the matched pattern was 'user'.
 
Is there a way to do the same thing with webapp2.Route? Can the lazy handler or the method_handler parameters be based on the matched patterns in template?
