python之Google 应用引擎 TypeError 问题

我在 google app engine 上使用 django 获得了一个简单的应用程序，我有两个看起来非常相同的类，但其中一个因 TypeError 而崩溃。

Traceback (most recent call last): 
  File "C:\Program Files (x86)\Google\google_appengine\google\appengine\tools\dev_appserver.py", line 3211, in _HandleRequest

TypeError: NotFoundPage() takes exactly 1 argument (0 given) 

我的类看起来像这样(main.py):

import os 
import datetime 
 
from google.appengine.ext import webapp 
from google.appengine.ext.webapp import template 
from google.appengine.ext.webapp.util import run_wsgi_app 
 
class BasePage(webapp.RequestHandler): 
   def initialize(self, request, response): 
       webapp.RequestHandler.initialize(self, request, response) 
       dir = os.path.join(os.path.dirname(__file__), "../templates") 
       self.template_path = os.path.abspath(dir) 
 
   def render_to_response(self, page, template_values): 
       page_path = os.path.join(self.template_path, page) 
       self.response.out.write(template.render(page_path, template_values)) 
 
 
class DefaultPage(BasePage): 
   def get(self): 
      visitor = Visitor() 
      visitor.ip = self.request.remote_addr 
      visitor.put() 
 
      page = Page() 
      page.title = "MY PORTAL" 
      page.subtitle = "Home" 
      page.name = self.request.path 
 
      visitors_query = Visitor.all().order('-added_on') 
      visitors = visitors_query.fetch(20) 
 
      self.render_to_response("main.html", 
        { 
            "page": page, 
            "visitors":  visitors, 
        }) 
 
 
def NotFoundPage(BasePage): 
   def get(self): 
      page = Page() 
      page.title = "MY PORTAL" 
      page.subtitle = "Not Found" 
      page.name = self.request.path 
 
      self.render_to_response("empty.html",  
        { 
           "page": page, 
        }) 
 
application = webapp.WSGIApplication( 
                                    [('/', DefaultPage), 
                                     ('/index.html', DefaultPage), 
                                     ('/.*', NotFoundPage), 
                                     ], 
                                    debug=True) 
 
def main(): 
    run_wsgi_app(application) 
 
if __name__ == "__main__": 
    main() 

当我访问/index.html 时，一切正常。但是当我转到/not-found.html 时，它因错误而崩溃。我不知道这个脚本有什么问题。也许我忽略了一些东西。请帮忙。

请您参考如下方法:

def NotFoundPage(BasePage): 

应该是:

class NotFoundPage(BasePage):
