WPF实战学习笔记32-登录、注册服务添加

增加全局账户名同步

增加静态变量

添加文件：Mytodo.Common.Models.AppSession.cs

ausing Prism.Mvvm;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Input;namespace Mytodo.Common.Models
{public class AppSession{private static String userName;/// <summary>/// A static property which you'd like to bind to/// </summary>public static String UserName{get{return userName;}set{userName = value;// Raise a change eventOnUserNameChanged(EventArgs.Empty);}}// Declare a static event representing changes to your static propertypublic static event EventHandler UserNameChanged;// Raise the change event through this static methodprotected static void OnUserNameChanged(EventArgs e){EventHandler handler = UserNameChanged;if (handler != null){handler(null, e);}}static AppSession(){// Set up an empty event handlerUserNameChanged += (sender, e) => { return; };}}
}

修改MainView绑定

1. 增加命名空间

xmlns:model="clr-namespace:Mytodo.Common.Models"

2. 修改textblock绑定

<TextBlockMargin="0,10"HorizontalAlignment="Center"Text="{Binding Path=(model:AppSession.UserName)}" />

给账户名赋值

修改Mytodo.ViewModels.LoginViewModel.cs

async private void Login()
{if (string.IsNullOrWhiteSpace(Account) ||string.IsNullOrWhiteSpace(Password)){aggregator.SendMessage("密码或账户为空，请重新输入", "Login");return;}var loginResult = await loginService.Login(new UserDto(){Account = Account,PassWord = Password});if (loginResult != null && loginResult.Status){//UserDto myuser= new UserDto() { UserName=loginResult.Result }// AppSession.UserNameAppSession.UserName = (loginResult.Result as UserDto).UserName;RequestClose?.Invoke(new DialogResult(ButtonResult.OK));return;}else{//登录失败提示...aggregator.SendMessage("密码或账户错误，请重新输入", "Login");}
}

添加注销功能

添加注销方法

修改文件：Mytodo.app.xaml.cs

public static void LoginOut(IContainerProvider containerProvider)
{Current.MainWindow.Hide();var dialog = containerProvider.Resolve<IDialogService>();dialog.ShowDialog("LoginView", callback =>{if (callback.Result != ButtonResult.OK){Environment.Exit(0);return;}Current.MainWindow.Show();});
}

添加注销命令，并初始化

修改文件：Mytodo.ViewModels.MainViewModel.cs

using Mytodo.Common;
using Mytodo.Common.Models;
using Mytodo.Extensions;
using Prism.Commands;
using Prism.Ioc;
using Prism.Mvvm;
using Prism.Regions;
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Runtime.CompilerServices;
using System.Text;
using System.Threading.Tasks;namespace Mytodo.ViewModels
{public class MainViewModel : BindableBase, IConfigureInterface{public MainViewModel(IRegionManager regm, IContainerProvider provider){MenuBars = new ObservableCollection<MenuBar>();//区域赋值this.regionManager = regm;this.provider = provider;//初始化命令操作NavigateCmd = new DelegateCommand<MenuBar>(Navigate);LoginOutCommand = new DelegateCommand(Logout);//实例化命令GoBackCmd = new DelegateCommand(() =>{if (journal != null && journal.CanGoBack)journal.GoBack();});GoFwrdCmd = new DelegateCommand(() =>{if (journal != null && journal.CanGoForward)journal.GoForward();});}private void Logout(){App.LoginOut(provider);}//添加变量private readonly IRegionManager regionManager;private readonly IContainerProvider provider;private IRegionNavigationJournal journal;//添加命令public DelegateCommand LoginOutCommand { get; set; }public DelegateCommand<MenuBar> NavigateCmd { get; private set; }/// <summary>/// 导航返回命令/// </summary>public DelegateCommand GoBackCmd { get; private set; }/// <summary>/// 导航前进命令/// </summary>public DelegateCommand GoFwrdCmd { get; private set; }//命令方法private void Navigate(MenuBar obj){if (obj == null || string.IsNullOrWhiteSpace(obj.NameSpace))return;regionManager.Regions[PrismManager.MainViewRegionName].RequestNavigate(obj.NameSpace, back =>{journal = back.Context.NavigationService.Journal;});}private ObservableCollection<MenuBar> menuBars;public ObservableCollection<MenuBar> MenuBars{get { return menuBars; }set { menuBars = value; RaisePropertyChanged(); }}void CreatMenuBar(){MenuBars.Add(new MenuBar { Icon = "Home", NameSpace = "IndexView", Title = "首页" });MenuBars.Add(new MenuBar { Icon = "FormatListChecks", NameSpace = "TodoView", Title = "待办事项" });MenuBars.Add(new MenuBar { Icon = "Notebook", NameSpace = "MemoView", Title = "备忘录" });MenuBars.Add(new MenuBar { Icon = "Cog", NameSpace = "SettingsView", Title = "设置" });}public void Configure(){CreatMenuBar();//导航到主页regionManager.Regions[PrismManager.MainViewRegionName].RequestNavigate("IndexView");}}
}

修改xaml，增加注销按钮

<materialDesign:PopupBox Panel.ZIndex="1"><materialDesign:PopupBox.ToggleContent><ImageWidth="50"Height="50"Margin="16,0,0,0"Source="../Images/user.jpg"><Image.Clip><EllipseGeometryCenter="25,25"RadiusX="25"RadiusY="25" /></Image.Clip></Image></materialDesign:PopupBox.ToggleContent><StackPanel><!--<Button Command="{Binding AppCenterCommand}" Content="个人中心"/>--><Button Command="{Binding LoginOutCommand}" Content="注销当前账户" /></StackPanel>
</materialDesign:PopupBox>

首页添加用户名和时间

修改文件：Mytodo.ViewModels.IndexViewModel.cs

public DateTime CurrTime
{get { return currTime; }set { currTime = value; RaisePropertyChanged(); }
}
private string title;public string Title
{get { return title; }set { title = value; RaisePropertyChanged(); }
}
private DateTime currTime;
private async void RefreshTimeAsync()
{while (true){await Task.Delay(1000);CurrTime = DateTime.Now;Title = "您好 " + AppSession.UserName + ", 现在是: " + currTime.ToString("yy-MM-dd") + " " + currTime.ToString("HH:MM:ss") + " " + currTime.ToString("ddd");}
}
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>();this.regionManager = provider.Resolve<IRegionManager>();//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);NavigateCommand = new DelegateCommand<TaskBar>(Navigate);this.dialog = dialog;CreatBars();RefreshTimeAsync();
}

修改bug

修改服务接口

修改ExecuteAsync()函数，修改HttpRestClient文件

using Newtonsoft.Json;
using RestSharp;
using RestSharp.Extensions;
using RestSharp.Serializers;
using RestSharp.Authenticators;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using MyToDo.Share;
using MyToDo.Share.Models;
using Microsoft.AspNetCore.Http;namespace Mytodo.Service
{/// <summary>/// Http本地客户端/// </summary>public class HttpRestClient{private readonly string? apiUrl;protected readonly RestClient? client;public HttpRestClient(string apiUrl){this.apiUrl = apiUrl;client = new RestClient();}/// <summary>/// 异步执行/// </summary>/// <param name="baseRequest"></param>/// <returns></returns>public async Task<ApiResponse> ExecuteAsync(BaseRequest baseRequest){var request = new RestRequest(baseRequest.Method);request.AddHeader("Content-Type", baseRequest.ContentType);if (baseRequest.Parameter != null)request.AddParameter("param", JsonConvert.SerializeObject(baseRequest.Parameter), ParameterType.RequestBody);client.BaseUrl = new Uri(apiUrl + baseRequest.Route);var response = await client.ExecuteAsync(request);var apires = JsonConvert.DeserializeObject<ApiResponse>(response.Content);if (apires.Status){///return JsonConvert.DeserializeObject<ApiResponse>(response.Content);return new ApiResponse(){Status = true,Result = JsonConvert.DeserializeObject<UserDto>(apires.Result.ToString()),Message = ""};}   elsereturn new ApiResponse(){Status = false,Result = null,Message = response.ErrorMessage};}public async Task<ApiResponse<T>> ExecuteAsync<T>(BaseRequest baseRequest){var request = new RestRequest(baseRequest.Method);request.AddHeader("Content-Type", baseRequest.ContentType);if (baseRequest.Parameter != null)request.AddParameter("param", JsonConvert.SerializeObject(baseRequest.Parameter), ParameterType.RequestBody);client.BaseUrl = new Uri(apiUrl + baseRequest.Route);var response = await client.ExecuteAsync(request);if (response.StatusCode == System.Net.HttpStatusCode.OK)return JsonConvert.DeserializeObject<ApiResponse<T>>(response.Content);elsereturn new ApiResponse<T>(){Status = false,Message = response.ErrorMessage};}}
}

调换注册界面数据绑定

<TextBoxMargin="0,5"md:HintAssist.Hint="请输入用户名"DockPanel.Dock="Top"Text="{Binding RUserDto.UserName}" />
<TextBoxMargin="0,5"md:HintAssist.Hint="请输入账号"DockPanel.Dock="Top"Text="{Binding RUserDto.Account}" />
