cherrypy URL问题

Question

我在cherrypy中有一个URL，类似于堆栈溢出：

http://sample.com/post/12345/hello-world

但是，我想让以下URL在cherrypy中也起作用：

http://sample.com/post/12345/hello-world?from=something&else=123

并应更正为：

http://sample.com/post/12345/hello-world

我怎么能这么做？

我正在使用popargs和_cp_dispatch，但没有成功。如有任何建议，将不胜感激。

谢谢

编辑

我让它基于saaj的答案工作，但是我想将代码移到index()，urls都返回404。

import cherrypy

class App:

@cherrypy.expose
def index(self, id, name = None, **kwargs):
  if kwargs:
    # do your querystring processing
    raise cherrypy.HTTPRedirect(cherrypy.url())

  if not name:
    # get name part for canonical url
    name = '{0}/hello-world'.format(id)
    raise cherrypy.HTTPRedirect(cherrypy.url(name))

    return '{0} {1} {2}'.format(id, name, kwargs)

if __name__ == '__main__':
  cherrypy.quickstart(App(), '/post', config)

更多的帮助是非常感谢的。我仍然是一个快乐的初学者。
