浅谈tornado项目应用设计

一.预备知识  

 最近开始尝试做一些tornado商城项目,在开始之前需要引入一些项目设计知识,如接口,抽象方法抽象类,组合,程序设计原则等,个人理解项目的合理设计可增加其灵活性,降低数据之间的耦合性,提高稳定性,下面介绍一些预备知识 

1.接口

  其实py中没有接口这个概念。要想实现接口的功能,可以通过主动抛出异常来实现

  接口作用:对派生类起到限制的作用

例:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""
接口,python中的接口,通过在父类中主动抛出异常实现
接口的作用:起到了限制的作用
"""

class IFoo:
    def fun1(self):
        pass
        raise Exception("----")

class Bar(IFoo):
    def fun1(self):
        #方法名必须和父类中的方法名相同,不然没办法正常执行,会抛出异常
        print("子类中如果想要调用父类中的方法,子类中必须要有父类中的方法名")
    def fun2(self):
        print("test")

obj = Bar()
obj.fun2()

2.抽象方法抽象类

  抽象类,抽象方法是普通类和接口的综合,即可以继承也可以起到限制作用

  由于python 本身没有抽象类、接口的概念,所以要实现这种功能得abc.py 这个类库,具体实现方法如下 :

#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""
抽象类,抽象方法
抽象类,抽象方法是普通类和接口的综合,即可以继承也可以起到限制作用
"""

import abc
class Foo(metaclass=abc.ABCMeta):
    def fun1(self):
        print("fun1")

    def fun2(self):
        print("fun2")

    @abc.abstractclassmethod
    def fun3(self):
        pass


class Bar(Foo):
    def fun3(self):
        print("子类必须有父类的抽象方法名,不然会抛出异常")


obj = Bar()
obj.fun1()
obj.fun2()
obj.fun3()

 3.组合

  python中“多用组合少用继承”,因为继承的偶合性太强,可以把基类,当做参数传入派生类中,用于解偶

如;

#!/usr/bin/env python
# -*- coding: utf-8 -*-
#继承

class Animals:
    def eat(self):
        print(self.Name + " eat")
    def drink(self):
        print(self.Name + " drink")

class Person(Animals):
    def __init__(self, name):
        self.Name = name

    def think(self):
        print(self.Name + " think")
obj = Person("user1")
obj.drink()
obj.eat()
obj.think()
继承
class Animals:
    def __init__(self,name):
        self.Name = name

    def eat(self):
        print(self.Name + " eat")

    def drink(self):
        print(self.Name + " drink")

class Person:
    def __init__(self, obj):
        self.obj = obj

    def eat(self):
        self.obj.eat()

    def think(self,name):
        print(name + " think")

animals = Animals("animals")
obj = Person(animals)
obj.think("person")
obj.eat()
组合

4.依赖注入

  刚接触理解的比较浅显

  像上一例中,如果有多层关系时,需要传入多个对象,为了解决这个问题就引入了依赖注入,如上例在Person类实例化时自动传入Animals对象

  那么,在引入依赖注入时先了解一下python类实例化过程中背后做了什么事情

class Foo:
    def __init__(self):
        self.name = 111
    
    
    def fun(self)
        print(self.name)
        
obj = Foo() #obj是Foo的实例化对象

在python中一切皆对象,Foo是通过type类创建的

例:

#!/usr/bin/env python
# -*- coding:utf-8 -*-

class MyType(type):

    def __call__(cls, *args, **kwargs):
        obj = cls.__new__(cls, *args, **kwargs)
        obj.__init__(*args, **kwargs)
        return obj


class Foo(metaclass=MyType):

    def __init__(self, name):
        self.name = name

    def f1(self):
        print(self.name)
 解释器解释:
    1.遇到 class Foo,执行type的__init__方法
    1.Type的init的方法里做什么么呢?不知道
        obj = Foo(123)
    3.执行Type的 __call__方法
        执行Foo类的 __new__方法
        执行Foo类的 __init__ 方法

先来了解几个概念

new 和 __init()和__metaclass__:

  • __new__函数是实例一个类所要调用的函数,每当我们调用obj = Foo()来实例一个类时,都是先调用__new__()

  • 然后再调用__init__()函数初始化实例. __init__()在__new__()执行后执行,

  • 类中还有一个属性 __metaclass__,其用来表示该类由 谁 来实例化创建,所以,我们可以为 __metaclass__ 设置一个type类的派生类,从而查看 类 创建的过程。

那么依赖注入的实现方法,自定义一个type方法,实例化类的时候指定由自定义的type方法创建,具体实现方法如下:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
# 依赖注入应用
#DI
class Mapper:
    __mapper_relation ={}

    @staticmethod
    def register(cls,value):
        Mapper.__mapper_relation[cls] = value

    @staticmethod
    def exist(cls):
        if cls in Mapper.__mapper_relation:
            return True
        return False

    @staticmethod
    def value(cls):
        return Mapper.__mapper_relation[cls]


class MyType(type):
    def __call__(self, *args, **kwargs):
        obj = self.__new__(self, *args, **kwargs)
        arg_list = list(args)
        if Mapper.exist(self):
            value=Mapper.value(self)
            arg_list.append(value)
        obj.__init__(*arg_list, **kwargs)
        return obj


#定义由谁来实例化
class Foo(metaclass=MyType):
    def __init__(self,name):
        self.name = name

    def f1(self):
        print(self.name)

class Bar(metaclass=MyType):
    def __init__(self,name):
        self.name = name

    def f1(self):
        print(self.name)

Mapper.register(Foo,"test1")
Mapper.register(Bar,"test12")
f=Foo()
print(f.name)
依赖注入应用

5.程序的设计原则

  1. 单一责任原则       

一个对象只对一个元素负责

优点;

  消除耦合,减小因需求变化引起代码僵化

  2.开放封闭原则

    对扩展开放,对修改关闭

    优点:

      按照OCP原则设计出来的系统,降低了程序各部分之间的耦合性,其适应性、灵活性、稳定性都比较好。当已有软件系统需要增加新的功能时,

      不需要对作为系统基础的抽象层进行修改,只需要在原有基础上附加新的模块就能实现所需要添加的功能。增加的新模块对原有的模块完全没有影响或影响很小,

      这样就无须为原有模块进行重新测试

    如何实现 ? 

      在面向对象设计中,不允许更必的是系统的抽象层,面允许扩展的是系统的实现层,所以解决问题的关键是在于抽象化。

      在面向对象编程中,通过抽象类及接口,规定具体类的特征作为抽象层,相对稳定,不需要做更改的从面可以满足“对修改关闭”的原则;而从抽象类导出的具体 类可以

      改变系统 的行为,从而满足“对扩展开放的原则"

  3.里氏替换原则  

    可以使用任何派生类替换基类
    优点:
      可以很容易的实现同一父类下各个子类的互换,而客户端可以毫不察觉
  4.接口分享原则
    对于接口进行分类避免一个接口的方法过多,避免”胖接口"
    优点:
      会使一个软件系统功能扩展时,修改的压力不会传到别的对象那里
    如何实现 ?
      得用委托分离接口
      利用多继承分离接口

  5.依赖倒置原则    

隔离关系,使用接口或抽象类代指
高层次的模块不应该依赖于低层次的模块,而是,都应该依赖于抽象
    优点:
      使用传统过程化程序设计所创建的依赖关系,策略依赖于细节,这是糟糕的,因为策略受到细节改变的影响。
      依赖倒置原则使细节和策略都依赖于抽象,抽象的稳定性决定了系统的稳定性
  6.依赖注入和控制反转原则
    
    使用钩子再原来执行流程中注入其他对象

二.tornado项目设计实例

  此实例只包含登录,写此实例目的在于更好的理解及应用以上的内容

1.目录规划

  

注:

  Infrastructure 目录:公共组件目录

  Model:业务逻辑处理目录

  Repository: 数据仓库及数据处理目录

  Statics:静态文件目录如(css,js,images等)

  UIAdmin: UI层

  Views:模板文件目录

  Application.py : 服务启动文件

2.业务访问流程

   介绍完目录规划,那就来讲讲业务访问流程及数据走向

  1. 启动服务后,客户端访问URL,根据tornado路由找到相对的handler进行处理
  2. 找到handler后其相对方法(get/post/delete/put)中调用Model逻辑处理层方法进行处理并接收处理结果
  3. Model逻辑处理层需
    • 创建接口
    • 建模
    • 创建协调层

   创建完之后 ,由协调层(这里通用Services)调用数据层方法并接收处理结果返回给handler

  4.数据处理层接收到Model调用后,处理数据并将数据返回给Model业务逻辑处理层

  5.最终handler接收到最终结果,进行判断处理,并将处理结果返回给用户

3.具体实施

  按照以上的访问流程来看配置文件

1.启动文件,路由关系配置

#!/usr/bin/env python
# -*- coding:utf-8 -*-
import tornado.ioloop
import tornado.web
from UIAdmin.Controllers import Account
from UIAdmin.Controllers import Region
from UIAdmin.Controllers import Customer
from UIAdmin.Controllers import Merchant
from UIAdmin import mapper

settings = {
    'template_path': 'Views',
    'static_path': 'Statics',
    'static_url_prefix': '/statics/',
}
application = tornado.web.Application([
    (r"/login", Account.LoginHandler),
    (r"/check", Account.CheckCodeHandler),
],**settings)

if __name__ == "__main__":
    application.listen(8000)
    tornado.ioloop.IOLoop.instance().start()
Application.py

注:

settings 中指定配置,如模板文件路径,静态文件路径等

application :路由配置,那个路径由那个handler进行处理

2.handler配置 

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import io
from Infrastructure.Core.HttpRequest import BaseRequestHandler
from Infrastructure.utils import check_code
from Model.User import UserService


class LoginHandler(BaseRequestHandler):
    def get(self, *args, **kwargs):
        self.render("Admin/Account/login.html")

    def post(self, *args, **kwargs):
        username = self.get_argument("username",None)
        email = self.get_argument("email",None)
        pwd = self.get_argument("pwd",None)
        code = self.get_argument("checkcode",None)
        service = UserService()
        result = service.check_login(user=username,email=email,pwd=pwd)
        #obj封装了所有的用户信息,UserModel对象
        if result and code.upper() == self.session["CheckCode"].upper():
            self.session['username'] = result.username
            self.redirect("/ProvinceManager.html")
        else:
            self.write("alert('error')")
hanler.py

handler中主要是针对数据访问方式的不同,给出不同的处理方法,并将结果返回给客户端

3.Model 逻辑处理层

  逻辑处理层中,着重看的有三点
  1. 建模
  2. 接口
  3. 协调

 建模  

#!/usr/bin/env python
# -*- coding: utf-8 -*-
#建模
from Infrastructure.DI.Meta import DIMetaClass

class VipType:

    VIP_TYPE = (
        {'nid': 1, 'caption': '铜牌'},
        {'nid': 2, 'caption': '银牌'},
        {'nid': 3, 'caption': '金牌'},
        {'nid': 4, 'caption': '铂金'},
    )

    def __init__(self, nid):
        self.nid = nid

    def get_caption(self):
        caption = None

        for item in VipType.VIP_TYPE:
            if item['nid'] == self.nid:
                caption = item['caption']
                break
        return caption

    caption = property(get_caption)


class UserType:

    USER_TYPE = (
        {'nid': 1, 'caption': '用户'},
        {'nid': 2, 'caption': '商户'},
        {'nid': 3, 'caption': '管理员'},
    )

    def __init__(self, nid):
        self.nid = nid

    def get_caption(self):
        caption = None

        for item in UserType.USER_TYPE:
            if item['nid'] == self.nid:
                caption = item['caption']
                break
        return caption

    caption = property(get_caption)


class UserModel:
    def __init__(self, nid, username,password, email, last_login, user_type_obj, vip_type_obj):
        self.nid = nid
        self.username = username
        self.email = email
        self.password = password
        self.last_login = last_login
        self.user_type_obj = user_type_obj
        self.vip_type_obj = vip_type_obj
建模

 接口

IUseRepository类:接口类,用于约束数据库访问类的方法

class IUserRepository:

    def fetch_one_by_user(self,user,pwd):
        """
        根据用户名和密码获取对象
        :param user:
        :param pwd:
        :return:
        """

    def fetch_one_by_email(self, user, pwd):
        """
        根据邮箱和密码获取对象
        :param user:
        :param pwd:
        :return:
        """
接口

协调

协调作用主要是调用数据处理层的方法,并将数据处理层处理后的结果返回给它的上一层的调度者

class UserService(metaclass=DIMetaClass):
    def __init__(self, user_repository):
        """
        :param user_repository: 数据仓库对象
        """
        self.userRepository = user_repository

    def check_login(self,user,email,pwd):
        if user:
            #数据仓库执行SQL后返回的字典
            #{"nid":1,username:xxx,vip:2,usertype:1}
            ret = self.userRepository.fetch_one_by_user(user,pwd)
        else:
            ret = self.userRepository.fetch_one_by_email(email,pwd)
        return ret
协调层UserService

4.Repository数据处理层

  将处理后结果(usermodel对象)返回给上一层调度者(UserService)

数据处理层

5.Handler最终处理

  接收到最终处理结果后判断,并返回数据给用户

注:

  有没有注意到UserService是怎么和数据处理层建立联系的?

  这里我们用到了依赖注入,具体配置如下:  

#!/usr/bin/env python
# -*- coding:utf-8 -*-
#依赖注入

class DIMapper:

    __mapper_dict = {}

    @staticmethod
    def inject(cls, arg):
        if cls not in DIMapper.__mapper_dict:
            DIMapper.__mapper_dict[cls] = arg

    @staticmethod
    def get_mappers():
        return DIMapper.__mapper_dict


class DIMetaClass(type):

    def __call__(cls, *args, **kwargs):
        # 获取配置的对应的对象,携带进入
        obj = cls.__new__(cls, *args, **kwargs)

        mapper_dict = DIMapper.get_mappers()
        if cls in mapper_dict:
            cls.__init__(obj, mapper_dict[cls])
        else:
            cls.__init__(obj, *args, **kwargs)
        return obj
Meta.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-
# 依赖注入绑定
from Infrastructure.DI import Meta
from Model.User import UserService
from Repository.Admin.UserRepository import UserRepository


Meta.DIMapper.inject(UserService,UserRepository())
