        # 1.简介

python实验作业，正好回顾一下小学二年级学习的pyqt，优化一下以前写的框架。（大二还在写这些，有点惭愧，不想花太多时间写，于是一晚上肝完了）

> 1.本项目在pyqt的框架上进一步封装，基于springMVC架构和springboot架构进行二次架构设计，参考笔者之前写的：[【快速调用】基于mvc架构的pyqt架构封装](https://blog.csdn.net/linZinan_/article/details/112460133)

> 2.源代码链接：[https://gitee.com/zeeland/covid-19-based-on-pyqt](https://gitee.com/zeeland/covid-19-based-on-pyqt)

**相较于上篇博客，本次架构优化如下：**

- 优化了启动类的启动流程

- 添加了页面调度器，可以更加方便的进行页面调度

- 在启动类中添加了驱动注册中心，添加了相关的数据库驱动和连接池驱动，可以更加灵活的对数据库进行操作

- 进一步封装了mysql service，可以同时兼容connector和pool两种连接方式

# 2.运行环境

- python3.7.6

- 使用pip安装下面的环境

```shell

pip install PyQt5

pip install request

pip install pymysql

pip install mysql

pip install dbutils

```

- 目录结构

# 3.需求分析

- 数据库存储所有的疫情信息，疫情信息包括：日期、城市名、新增病例、数量、确诊数量、疑似病例数据、治愈病例数量

- 可以用表格查看当前所有的疫情信息（定义排序规则）(**懒得做**)，并查询指定城市的疫情信息。

- 可以自动获取今日疫情信息也可以手动添加今日疫情信息

- 可以指定当前删除某个城市的信息

# 4.设计思路

啥也不管，先把架构搭起来，各个目录的文件夹先创建好，然后再做UI，把UI的大题样式确定下来。然后设计数据库模型，然后构建数据流逻辑，大体流程是这样。

![image.png](https://img-blog.csdnimg.cn/img_convert/c0299f9e4b41db0c47dfcf71cb6263ec.png)

- 需求上述已经确定好了。

- 框架搭建上述也做了一下大概描述，整个架构都是参考springMVC和springboot框架进行搭建的。

- UI设计过程省略。

- 解析疫情数据参考：[【爬虫+可视化】Python爬取疫情数据，并做可视化展示](https://blog.csdn.net/m0_48405781/article/details/121823049?ops_request_misc=%257B%2522request%255Fid%2522%253A%2522165235528016780366543939%2522%252C%2522scm%2522%253A%252220140713.130102334..%2522%257D&request_id=165235528016780366543939&biz_id=0&utm_medium=distribute.pc_search_result.none-task-blog-2~all~top_click~default-2-121823049-null-null.142^v9^control,157^v4^new_style&utm_term=%E7%88%AC%E5%8F%96%E7%96%AB%E6%83%85%E6%95%B0%E6%8D%AE&spm=1018.2226.3001.4187)，笔者参考了该博客的方法，自己爬了一个不同的API，解析里面的JSON数据，详细的信息在下面这两个文件，可以学习一下。

![image.png](https://img-blog.csdnimg.cn/img_convert/069af97eda6def246513841a1adeefc5.png)

- 根据解析的数据，数据库建成了下图的样子。一个省份疫情信息表，一个地区疫情信息表，地区外键指向省份id的主键。

![image.png](https://img-blog.csdnimg.cn/img_convert/cdadfe96575c13c8d89e0455033246b6.png)

- model设计，两张表对应的实体类在pojo中，展示一个epi_province的代码

```python

class EpiProvince:

    def __init__(self,*args,**kwargs):

        # 地区名称

        self.province_name = None

        # 日期

        self.province_today_date = None

        # 更新时间

        self.province_total_update_time = None

        # 死亡人数

        self.province_total_dead = None

        # 治愈人数

        self.province_total_heal = None

        # 现有确诊

        self.province_total_now_confirm = None

        # 累积确诊

        self.province_total_confirm = None

        # 今日新增

        self.province_today_confirm = None

        # 逻辑删除

        self.is_delete = None

        # judge if the args is empty

        try:

            if len(args) == 0:

                self.province_name = kwargs['data']['province_name']

                self.province_today_date = kwargs['data']['province_today_date']

                self.province_total_update_time = kwargs['data']['province_total_update_time']

                self.province_total_dead = kwargs['data']['province_total_dead']

                self.province_total_heal = kwargs['data']['province_total_heal']

                self.province_total_now_confirm = kwargs['data']['province_total_now_confirm']

                self.province_total_confirm = kwargs['data']['province_total_confirm']

                self.province_today_confirm = kwargs['data']['province_today_confirm']

                self.is_delete = kwargs['data']['is_delete']

            else:

                args = args[0]

                self.province_name = args[1]

                self.province_today_date = args[2]

                self.province_total_update_time = args[3]

                self.province_total_dead = args[4]

                self.province_total_heal = args[5]

                self.province_total_now_confirm = args[6]

                self.province_total_confirm = args[7]

                self.province_today_confirm = args[8]

                self.is_delete = args[9]

        except Exception as e:

            print('[error]',e)

    def __str__(self):

        # print all info

        return 'province_name:%s,province_today_date:%s,province_total_update_time:%s,' \

               'province_total_dead:%s,province_total_heal:%s,province_total_now_confirm:%s,province_total_confirm:' \

               '%s,province_today_confirm:%s,is_delete:%s' % (self.province_name, self.province_today_date,

                self.province_total_update_time, self.province_total_dead,self.province_total_heal,

                self.province_total_now_confirm, self.province_total_confirm,

                self.province_today_confirm, self.is_delete)

```

- service实现：封装CRUD操作，可以更加方便的操作数据库实体（参考mybatis架构），节选代码如下所示。

```python

from config.MysqlConfig import MysqlConfig

class EpiProvinceService(MysqlConfig):

    def __init__(self,pool=None):

        super().__init__(pool=pool)

    def get_all(self):

        try:

            self.cursor.execute('select * from epi_province order by province_total_update_time desc')

            result = self.cursor.fetchall()

            return result

        except Exception as e:

            print('[error]',e)

            return None

    def get_count(self):

        try:

            self.cursor.execute('select count(*) from epi_province')

            result = self.cursor.fetchone()

            return result[0]

        except Exception as e:

            print('[error] EpiProvinceService get_count:',e)

            return None

    def get_by_name(self,province_name):

        try:

            # 查找里面含有有该字符串的数据

            self.cursor.execute('select * from epi_province where province_name like %s',(province_name+"%",))

            result = self.cursor.fetchall()

            return result

        except Exception as e:

            print('[error] EpiProvinceService get_by_name err:',e)

            return None

    def insert(self,epi_province):

        try:

            # find if has the same update time info, if has, then insert new one, if not, then do nothing

            self.cursor.execute('select * from epi_province where province_total_update_time = %s',

                                (epi_province.province_total_update_time,))

            result = self.cursor.fetchone()

            if result:

                # do nothing

                print('[info] EpiProvinceService insert: has the same data')

            else:

                # insert

                self.cursor.execute('insert into epi_province (province_name,province_today_date,'

                                    'province_total_update_time,province_total_dead,province_total_heal,'

                                    'province_total_now_confirm,province_total_confirm,province_today_confirm,'

                                    'is_delete) values (%s,%s,%s,%s,%s,%s,%s,%s,%s)',(epi_province.province_name,

                                        epi_province.province_today_date, epi_province.province_total_update_time,

                                        epi_province.province_total_dead, epi_province.province_total_heal,

                                        epi_province.province_total_now_confirm, epi_province.province_total_confirm,

                                        epi_province.province_today_confirm, epi_province.is_delete))

                self.conn.commit()

                print('[info] insert successfully')

        except Exception as e:

            print('[error] EpiProvinceService insert err:',e)

            self.conn.rollback()

    def delete(self,province_name,update_time):

        try:

            self.cursor.execute('delete from epi_province where province_name = %s and province_total_update_time = %s',

                                (province_name,update_time))

            self.conn.commit()

        except Exception as e:

            print('[error] EpiProvinceService delete err:',e)

            self.conn.rollback()

    def __del__(self):

        try:

            self.cursor.close()

            self.conn.close()

        except Exception as e:

            print('[error] db close',e)

```

- controller实现的思想参考:[【快速调用】基于mvc架构的pyqt架构封装](https://blog.csdn.net/linZinan_/article/details/112460133)

程序设计到这里差不多就结束了，最后是主程序入口设计，如下：

```python

from PyQt5 import QtWidgets

from controller.HomeController import HomeController

from config.PoolConfig import PoolConfig

"""

@description: application gateways

"""

class SpireApplication:

    def __init__(self):

        # driver registration_list

        self.registration_list = {}

        # page dispatcher

        self.disp = None

        self.driver_registration()

        self.disp = PageDispatcher(self.registration_list)

    def driver_registration(self):

        self.pool_config = PoolConfig()

        self.registration_list['pool_config'] = self.pool_config

        print(self.registration_list)

        print('[sys] driver registered finish')

        

"""

@description: application page dispatcher,用作页面调度,控制不同的页面

@param      : registration_list驱动中心

"""

class PageDispatcher:

    def __init__(self,registration_list=None):

        self.registration_list = registration_list

        self.page_home_show(registration_list)

        print('[sys] page dispatcher finish')

    def page_home_show(self,registration_list=None):

        self.page_home = HomeController(registration_list=registration_list)

        self.page_home.show()

# main Application

if __name__ == "__main__":

    import sys

    app = QtWidgets.QApplication(sys.argv)

    a = SpireApplication()

    sys.exit(app.exec_())

```
