客户端详细设计

版本信息

当前版本: v0.9测试版

当前版本的界面属于类似于毛坯房的只有UI结构和功能而没有美化，且所有的图片显示均尚未处理,均使用了QLabel进行占位

用户界面设计

在使用代码工具编写界面前，可以先使用作图工具设计（“画”）一个UI界面出来，这样子有助于将UI设计与代码开发有一定程度的解耦合。降低开发难度

客户端实现

戳我🔗去github的release页面获取当前版本的源码

开发环境

因为当时遇到了些网络问题，所以下载了Qt 6.7.3

开发平台:Windows 11 家庭中文版
QT版本 QT6.7.3
QtCreator版本 15.0.0(community)

文件结构

由于C++提供的特性，对函数的实现可以有两大选择:

在.h文件中声明和实现同时完成
在.h中声明，在.cpp中实现

对于一些比较简单的对象，就比如下面的核心数据结构，我们采用在一个.h文件中声明和实现。

而对于比较复杂的对象，比如对QT的界面对象的封装，我们就采用声明与实现分离的方式

这样有个好处，就是有哪些成员变量和成员函数可以很清晰地在.h文件中找到，而如果要创建/跳转到实现，可以方便地使用快捷键:

在.cpp文件中创建实现: alt + enter
跳转到定义: ctrl + 鼠标左键 / F2(这个可设置)
指针返回到上一个位置: 鼠标侧键 / alt + 方向键←

核心数据结构实现

我们需要一套核心的数据结构用于在数据库，服务端和客户端之间进行数据传输,所以将核心的数据结构在单独的头文件中实现，并且保持与服务端同步

同时有一些通用的工具函数写实现在了这个文件中:

getFileName根据路径获取文件名(用于打印日志)
formatTime根据时间戳获取格式化的时间文本
getSecTime获取秒级时间戳
TAG宏定义规定日志打印的前缀
LOG()宏定义打印日志用的函数

关于命名空间:为了防止命名冲突，这里使用了命名空间btyGoose，即项目名BeautyGoose的缩写

MainWidget界面流转实现

本项目的界面流转方案有如下要点:

静态页面:页面在生成后基本不会自动发生变化，除非触发刷新重新生成页面
临时性: 所有的页面都属于临时生成，在切换时原本的界面直接删除，释放内存，不作保留
自动生成: MainWidget在控制界面的生成时，仅负责传入数据，具体的界面生成由界面类的构造函数自动生成
信号槽机制通信: MainWidget与前台的界面对象的交互仅有界面对象发信号和MainWidget接收信号并执行槽函数，因此每一次生成界面时，都要连接界面对象的信号和自己的槽函数

对于界面流转，我们重点实现两个函数:

构造函数: 为界面切换准备
clearAll()函数：清除界面内容

下面仅展示部分代码

MainWidget::MainWidget(QWidget *parent)
    : QWidget(parent)
    , ui(new Ui::MainWidget)
{
    ui->setupUi(this);
    this->setFixedSize(1600,900);
    this->setWindowIcon(QIcon(QPixmap(":/qsrc/icon.png")));
    QGridLayout* layout = new QGridLayout;
    this->setLayout(layout);
    //初始化信号连接
    initAccountResponseConnection();
    initConsumerResponeConnection();
    initMerchantResponseConnection();
    initAdminResponseConnection();
    // toRegisterSlot();
    toNameLoginSlot();      //转到用户名登录界面
}

void MainWidget::clearAll()
{
    QLayout* layout = this->layout();
    while(layout->count())
    {
        QLayoutItem* obj=layout->takeAt(0);
        if(obj->widget())
        {
            delete obj->widget();
        }
    }
}

注册界面实现

目前注册界面为简单实现，对输入的合法性判断较少，主要使用了如下QT类

<QRadioButton>提供了单选按钮,用于选择账户类型
<QLineEdit>用于输入单行文本，也提供了密码输入模式
<QPushButton>提供了可点击的按钮
<QTextEdit>用于输入多行文本，这里属于误用，使用QLineEdit更合适
<QMessageBox>用于简单地通过文本弹窗的方式输出提示信息
<QRegularExpression>,<QRegularExpressionValidator>提供正则表达式对手机号码等输入进行合法性判断
<QGridLayout>表格布局，用于较为简单地使用QT的布局功能

导航栏实现

参照前面的界面设计图我们可以看到很多界面都有个侧导航栏是一样的，因此我们大可以继承QWidget封装一个导航栏控件类。

因为单纯的导航栏控件比较简单，所以我们只使用一个Nav.h头文件

由于消费者和商家的导航栏切换到的是不同的界面，所以我们这边简单处理，单独实现两种导航栏类

消费者菜品列表界面实现

这个界面就属于比较复杂的界面了，会采用多层嵌套,这样开发的好处如下:

简化开发难度:将写一个大的类拆分成多层嵌套聚合的类，这样一层一层地独立开发能够降低开发难度
降低数据传递难度: 我们对打包好的数据的处理也是逐层解包拿到每一层需要的数据
灵活性高: 这样的多层嵌套可以很好地解耦合，提高灵活性
聚焦信号: 如下图所示，虽然在这个界面中，可能会有很多空间，但通过信号的层层转发的方式，通过一次或多次多对一的转发方式，最终让信号只从这个最大的界面控件发送传递给MainWidget用于处理。

消费者菜品详情窗口实现

虽然我们把它称为窗口，但实际上我们使用的是<QDialog>类

可能是出于开发失误，或者有更多的考量，具体的界面实现还是继承了QWidget类封装在ConsumerDishDetailWidget中，而对窗口的实现，则是另外封装ConsumerDishDetailWindow类并持有ConsumerDishDetailWidget指针的方式来实现窗口。

可能是为了使窗口能够更方便地加入动态性，对于所有的窗口，MainWidget都存有它们的指针。

数据中心类实现

按照之前的分层，数据中心便是客户端端业务逻辑层之下的客户端数据层，主要功能如下：

发起异步数据获取请求: 当MainWidget需要获取某个数据用于构建界面时，需要调用DataCenter对象进行异步获取数据
缓存数据: 所有从网络层传输到客户端的数据都缓存在数据中心中，同时可供MainWidget和NetClient（网络客户端）统一获取数据
提供数据就绪信号: 当NetClient把数据中心的数据就绪时，它会发送数据中心提供的就绪信号，以此通知MainWidget
读取配置文件: 为了能够方便地修改可配置参数，我们选择使用配置文件，这里用的是Json,而对配置文件的读取由数据中心类完成

特点: 单例模式。我们采用1.构造函数私有化 2.删除拷贝构造 3.删除赋值拷贝 4.提供静态getInstance()接口四步走来实现数据中心类的单例模式，因为整个客户端进程只需要一个数据中心，所以适合使用严格的单例模式

网络客户端

NetClient负责把参数和数据中心的数据进行序列化，通过HTTP的POST请求的body正文发送给服务端，并通过绑定响应信号到lambda表达式处理响应的报文，将响应的数据存入数据中心，或者通过信号传参发送出去

当前版本使用的是Json数据格式，以后也可以升级为效率更高的protobuf
