Python tornado.wsgi.WSGIApplication问题：_调用__恰好接受3个参数（给定2个）

作为一个项目的一部分，我一直在尝试移植一个Tornado服务器，以便在Google应用程序引擎上工作。由于应用程序引擎没有实现普通Tornado的异步功能，我一直在尝试将主应用程序转换为WSGIApplication。正常的主代码工作正常（请原谅导入和格式化，尝试遵循其他示例会造成混乱）：

我可以访问网页，浏览网站，效果很好。如果我将第24行更改为返回tornado.wsgi.WSGIApplication，如下所示：

import wsgiref
import tornado.wsgi
import tornado.web
import tornado.httpserver
import os
import Handlers
from tornado.options import define, options

define("port", default=8000, help="run on the given port", type=int)

def application():
    handlers=[(r"/", Handlers.MainHandler),
            (r"/Login", Handlers.LoginHandler),
            (r"/ViewHistory",Handlers.ViewHistoryHandler),
            (r"/UploadFile", Handlers.UploadHandler),
            (r"/Index", Handlers.IndexHandler),
            (r"/About", Handlers.AboutHandler),
            (r"/Profile", Handlers.ProfileHandler)]

    settings=dict(template_path=os.path.join(os.path.dirname(__file__), "templates"),
                static_path=os.path.join(os.path.dirname(__file__), "static"),
                debug=True)

    return tornado.wsgi.WSGIApplication(handlers, **settings)

def main():
    tornado.options.parse_command_line()
    http_server = tornado.httpserver.HTTPServer(application())
    http_server.listen(options.port)
    tornado.ioloop.IOLoop.instance().start()

if __name__ == "__main__":
    main()

它也运行得很好。但是，当我尝试访问任何网页时，会出现以下错误：

我对此一无所知，谷歌也没有发现任何人有同样的问题（除了那个建议在Tornado文件中捣乱的家伙，这对应用程序引擎AFAIK没有帮助）。以前是否有其他人见过此错误，或者可以发现当默认应用程序没有崩溃时WSGIApplication崩溃的原因？

这里的名称“Application”不幸超载-tornado.web.Application和WSGIApplication与服务器的接口不同。tornado.web.Application可由tornado HTTPServer使用，但WSGIApplication必须在WSGI容器中运行。在应用程序引擎部署中，您只需在配置文件中直接提到您的WSGIApplication实例，而不必提及tornado.httpserver。要将wsgi应用程序适配到tornado.httpserver，请使用tornado.wsgi.WSGIContainer:

httpserver（WSGIContainer（application（））
