注意：本实现与视频不一致。本实现中单独做了汇总接口，而视频中则合并到国todo接口当中了。

• 添加汇总webapi接口
• 添加汇总数据客户端接口
• 总数据客户端接口对接3
• 首页数据模型

添加数据汇总字段类

新建文件MyToDo.Share.Models.SummaryDto

using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace MyToDo.Share.Models
{public class SummaryDto:BaseDto{private int sum;public int Sum{get { return sum; }set { sum = value; OnPropertyChanged(); }}private int compeleteCnt;public int CompeleteCnt{get { return compeleteCnt; }set { compeleteCnt = value; OnPropertyChanged(); }}private int  memoCnt;public int  MemoCnt{get { return memoCnt; }set { memoCnt = value; OnPropertyChanged(); }}private string? compeleteRatio;public string? CompeleteRatio{get { return compeleteRatio; }set { compeleteRatio = value; OnPropertyChanged(); }}private ObservableCollection<ToDoDto> todoList;public ObservableCollection<ToDoDto> TodoList{get { return todoList; }set { todoList = value; }}/// <summary>/// MemoList/// </summary>private ObservableCollection<MemoDto> memoList;public ObservableCollection<MemoDto> MemoList{get { return memoList; }set { memoList = value; }}}
}

添加汇总webapi接口

添加汇总接口

添加文件：MyToDo.Api.Service.ISummary

using MyToDo.Share.Parameters;namespace MyToDo.Api.Service
{public interface ISummary{Task<ApiReponse> GetAllInfo(SummaryParameter parameter);}
}

实现汇总接口

添加文件：MyToDo.Api.Service.Summary

using Arch.EntityFrameworkCore.UnitOfWork;
using AutoMapper;
using MyToDo.Api.Context;
using MyToDo.Share.Models;
using MyToDo.Share.Parameters;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Collections.ObjectModel;namespace MyToDo.Api.Service
{public class Summary : ISummary{private readonly IUnitOfWork work;private readonly IMapper mapper;public Summary(IUnitOfWork work,IMapper mapper){this.work = work;this.mapper = mapper;}public async Task<ApiReponse> GetAllInfo(SummaryParameter parameter){try{SummaryDto sumdto = new SummaryDto();//获取所有todo信息var Pagetodos = await work.GetRepository<Todo>().GetPagedListAsync(pageIndex: parameter.PageIndex, pageSize: parameter.PageSize, orderBy: source => source.OrderByDescending(t => t.CreateDate));//获取所有memo信息var Pagememos = await work.GetRepository<Memo>().GetPagedListAsync(pageIndex: parameter.PageIndex, pageSize: parameter.PageSize, orderBy: source => source.OrderByDescending(t => t.CreateDate));//汇总待办数量sumdto.Sum = Pagetodos.TotalCount;//统计完成数量var todos = Pagetodos.Items;sumdto.CompeleteCnt = todos.Where(t => t.Status == 1).Count();//计算已完成比率sumdto.CompeleteRatio = (sumdto.CompeleteCnt / (double)sumdto.Sum).ToString("0%");//统计备忘录数量var memos = Pagememos.Items;sumdto.MemoCnt=Pagememos.TotalCount;//获取todos项目与memos项目集合sumdto.TodoList = new ObservableCollection<ToDoDto>(mapper.Map<List<ToDoDto>>(todos.Where(t => t.Status == 0)));sumdto.MemoList = new ObservableCollection<MemoDto>(mapper.Map<List<MemoDto>>(memos));return new ApiReponse(true, sumdto);}catch (Exception ex){return new ApiReponse(false, ex);}}}
}

添加控制器

添加文件MyToDo.Api.Controllers.SummaryController

using Microsoft.AspNetCore.Mvc;
using Microsoft.VisualBasic;
using MyToDo.Api.Service;
using MyToDo.Share.Models;
using MyToDo.Share.Parameters;namespace MyToDo.Api.Controllers
{[ApiController][Route("api/[controller]/[action]")]public class SummaryController:ControllerBase{private readonly ISummary service;public SummaryController(ISummary tService){this.service = tService;}[HttpGet]public async Task<ApiReponse> GetAllInfo([FromQuery] SummaryParameter parameter)=>await service.GetAllInfo(parameter);}
}

依赖注入

文件：webapi.Program.cs

添加：

builder.Services.AddTransient<ISummary, Summary>();

添加客户端数据接口

添加接口

新建文件：Mytodo.Service.ISummeryService.cs

using MyToDo.Share;
using MyToDo.Share.Contact;
using MyToDo.Share.Models;
using MyToDo.Share.Parameters;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace Mytodo.Service
{public interface ISummeryService{//public async Task<ApiResponse<SummaryDto>> GetAllInfo(SummaryParameter parameter)Task<ApiResponse<SummaryDto>> GetAllInfo(SummaryParameter parameter);}
}

实现接口

添加文件：Mytodo.Service.SummeryService

using MyToDo.Share;
using MyToDo.Share.Contact;
using MyToDo.Share.Models;
using MyToDo.Share.Parameters;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace Mytodo.Service
{public class SummeryService : ISummeryService{private readonly HttpRestClient client;private readonly string ServiceName="Summary";public SummeryService(HttpRestClient client){this.client = client;}public async Task<ApiResponse<SummaryDto>> GetAllInfo(SummaryParameter parameter){BaseRequest request = new BaseRequest();request.Method = RestSharp.Method.GET;//如果查询字段为空request.Route = $"api/{ServiceName}/GetAllInfo?PageIndex={parameter.PageIndex}" + $"&PageSize={parameter.PageSize}";//request.Route = $"api/{ServiceName}/GetAll?PageIndex={parameter.PageIndex}" + $"&PageSize={parameter.PageSize}" + $"&search={parameter.Search}";return await client.ExecuteAsync<SummaryDto>(request);}}
}

依赖注入

修改文件App.xaml.cs 添加内容

containerRegistry.Register<ISummeryService, SummeryService>();

首页对接接口

修改UI层绑定

修改文件：Mytodo.Views.IndexView.xaml

由

ItemsSource="{Binding TodoDtos}"
ItemsSource="{Binding MemoDtos}"

修改为

ItemsSource="{Binding Summary.TodoList}"
ItemsSource="{Binding Summary.MemoList}"

新建summary实例，并初始化

修改文件：Mytodo.ViewModels.IndexViewModel.cs

public SummaryDto Summary
{get { return summary; }set { summary = value; RaisePropertyChanged(); }
}
private SummaryDto summary;

新建summary服务实例，并初始化

private readonly ISummeryService summService;
public IndexViewModel(IContainerProvider provider,IDialogHostService dialog) : base(provider)
{//实例化接口this.toDoService= provider.Resolve<ITodoService>();this.memoService = provider.Resolve<IMemoService>();this.summService= provider.Resolve<ISummeryService>();//初始化命令EditMemoCmd = new DelegateCommand<MemoDto>(Addmemo);EditTodoCmd = new DelegateCommand<ToDoDto>(Addtodo);ToDoCompltedCommand = new DelegateCommand<ToDoDto>(Compete);ExecuteCommand = new DelegateCommand<string>(Execute);this.dialog = dialog;CreatBars();
}

添加首页数据初始化函数

/// <summary>
/// 更新首页所有信息
/// </summary>
private async void UpdateData()
{UpdateLoding(true);var summaryResult = await summService.GetAllInfo(new SummaryParameter() { PageIndex = 0, PageSize = 1000 });if (summaryResult.Status){Summary = summaryResult.Result;Refresh();}UpdateLoding(false);
}
public override async void OnNavigatedTo(NavigationContext navigationContext)
{UpdateData();base.OnNavigatedTo(navigationContext);
}void Refresh()
{TaskBars[0].Content = summary.Sum.ToString();TaskBars[1].Content = summary.CompeleteCnt.ToString();TaskBars[2].Content = summary.CompeleteRatio;TaskBars[3].Content = summary.MemoCnt.ToString();
}

用summary的字段替换掉TodoDtos与MemoDtos

更新添加、编辑、完成命
