Python MVC路由

Question

我有一个和这个问题一样的问题；——从来没有人回答过。在

我希望能够以类似的方式发送我的请求ASP.netMVC有。在

例如，address/Home/Index/query string/应该将请求映射到HomeController并调用Index方法。在

我为此做了一个实现，它很有效，但我想知道一个更好的方法来实现它。我已经 我刚开始第一次使用googleappengine和Python，在开发网站和web应用程序方面我没有太多经验。在

这是我的实现

Yaml文件：

- url: /.*
script: router.app

路由配置：

^{pr2}$

路由器

class Router(webapp2.RequestHandler):

    def getControllerName(self, handler):
            handler = handler.lower()
            if(len(handler) == 0):
                    """ Error - redirect to error page """
                    return webapp2.redirect('/Error/')
            if len(handler) == 1:
                    handler = handler[0].capitalize()
            else:
                    handler = handler[0].capitalize() + handler[1:]

            handler = handler + 'Controller'

            return handler

    def getActionName(self, method):
            method = method.lower()
            if(len(method) == 0):
                    """ Error - redirect to error page """
                    return webapp2.redirect('/Error/')
            if len(method) == 1:
                    method = method[0].capitalize()
            else:
                    method = method[0].capitalize() + method[1:]

            requestType = self.request.method.lower()
            requestType = requestType[0].capitalize() + requestType[1:]

            return method

    def loadController(self, controllerName):
            """ Load the controller """
            try:
                    fileName, pathName, description = imp.find_module(controllerName, None)
                    module = imp.load_module(controllerName, fileName, pathName, description)

                    # Add checking if class was found
                    controllerRef = getattr(module, controllerName)
                    return controllerRef

            except ImportError, args:
                    logging.error('Error importing controller. ' + pprint.saferepr(args))
            except Exception, args:
                    logging.error('Exception. ' + pprint.saferepr(args))
            finally:
                    fileName.close()

    def loadAction(self, controller, actionName):
            try:
                    actionRef = getattr(controller, actionName)
            except Exception, args:
                    logging.error('Exception. ' + pprint.saferepr(args))
            return actionRef

    def callController(self, controllerName, actionName, query):
            try:
                    """ Load the controller """
                    controllerRef = self.loadController(controllerName)
                    controller = controllerRef(self, query)
                    actionRef = self.loadAction(controller, actionName)
                    actionRef()
            except Exception, args:
                    logging.error('Exception. ' + pprint.saferepr(args))

    def map(self, handler, method, query):
            query = query.lower()
            """ Create Names for Controller and Action"""
            controllerName = self.getControllerName(handler)
            actionName = self.getActionName(method)

            self.callController(controllerName, actionName, query)

这是我的家庭控制器：

class HomeController(MVC.Controller):

    def Index(self):

            path = os.path.join(os.path.dirname('Views/Home/'), 'home.html')
            self.Request.response.out.write(template.render(path, None))
