        # self.write('我的第一个简陋网站……')
        self.render('查找.html')
# 路由
application = web.Application([
            (r"/", MainPageHandler),
        ])
# application = web.Application([
#             (r"/index", MainPageHandler),

# socket服务
if __name__ == '__main__':
        http_server = httpserver.HTTPServer(application)
        http_server.listen(8080)  # 设置端口
        ioloop.IOLoop.current().start()
