与popagrs装饰的Cherrypy调度员。子节点路由

Question

我想让以下网址回复

1. / book / [bookname]（工作）
2. / book / getdetails / [bookname]（工作）
3. / book / [bookname] / page / [pagenumber]（工作）
4. / book / [bookname] / page / getdetails / [pagenumber] （不工作）
5. / book / [bookname] / page / test（working）

基本服务处理程序：

class Service(object):
    def __init__(self):
        self.book = Book()

    @cherrypy.expose
    def index(self):
        return 'normal page'

图书类：

@cherrypy.popargs('book_name')
class Book(object):

    def __init__(self):
        self.page = Page()

    @cherrypy.expose
    @cherrypy.tools.json_out()
    def index(self, book_name):
        return {"book name": book_name}

    @cherrypy.expose
    @cherrypy.tools.json_out()
    def getdetails(self, book_name):
        return {"details": bookname}

Page Class：

@cherrypy.popargs('page_number')
class Page(object):

    @cherrypy.expose
    @cherrypy.tools.json_out()
    def index(self, book_name, page_number):
        return {"book": book_name, "no": page_number}

    # DOES NOT WORK AS EXPEXTED
    # @cherrypy.expose
    # @cherrypy.tools.json_out()
    # def getdetails(self, book_name, page_number):
    #     return {"book": book_name, "no": page_number}

    @cherrypy.expose
    @cherrypy.tools.json_out()
    def test(self, book_name):
        return {"details": "some test"}

服务是根类

if __name__ == '__main__':
    cherrypy.quickstart(Service())
