mall_wsgi

介绍

使用wsgiref和jinja2等实现了符合wsgi协议的轻量化WEB框架,并实现了session和重定向功能,并应用到一个mall系统中

软件架构

软件架构说明

run.py

程序运行入口
调用from wsgiref.simple_server import make_server 实现微服务
从视图函数中将实例化的app导入并在微服务中启动。

wsgi_mall.sql

数据库结构和数据

wsgi.py

符合wsgi协议的微服务框架主体,
函数:

listdir
将指定路径(path)下的所有文件的路径递归存入list_name中

redirect
重定向
通过设置响应代码为302 实现页面重定向

hash
调用hashlib.md5方法对数据字段进行散列

getRandom
获得随机字符串 默认长度为16

类:

Application
初始化生成url和session空字典
rout方法
仿照flask实现路由装饰器
__call__
访问入口
获取环境上传的post 和 get 数据
判断当前请求路径是否在urls中
若在则运行相应的视图函数获得返回值
由于有重定向功能的返回是有三个参数,普通为字符串类型则判断分别处理
分别设置200 和302请求响应状态
若访问路径没有在路由中则说明可能是静态文件 按照不同的文件设置不同的请求头返回
若不符合静态文件的规则 则说明路径不存在返回404
优化为 erro视图内容

post_data方法

使用multipart处理post数据
由于前端需要传文件
使用原有parse的方法不能满足要求故做此改进
返回值为字典

get_data方法
使用parse.parse_qs方法解析
返回参数字典

set_session方法

获取当前请求的cookie字段 对其进行md5 hash散列确保字段长度适当,将其作为session的键 及每个用户(浏览器)有相应的session储存地
使用字典的setdefault方法对已有session取值或者返回空字典
将更新的session使用update方法进行更新
从而更新当前用户的session字典

get_session方法
获取当前用户的cookie并MD5散列 通过该值进行取值返回

render方法

集成使用jinja2模板系统
在其中将session自动存入参数中以便前端使用

views.py

视图函数

不同数据表的key值首先声明 方便转换

deal_tags函数:
将tags用空格分割的字符串转为列表

登陆视图函数中会将登陆信息存入session
登出视图会将登陆标准设为False
注册视图成功注册后会转跳到登陆界面

我的功能所有视图都有基于session的登陆验证

其余视图函数不做赘述

ORM.py

mysql.connector实现sql的执行
只是简单的封装

关于select的说明 对查询的结果将其按照参数key的模式转为字典后使用Dict2Obj转为对象方便取值

前端模板文件:

base.html

样式基础导航栏和需要用的的样式文件等的设置 其余文件基于此作为基本模板编写
