背水一战 Windows 10 (83) - 用户和账号: 数据账号的添加和管理, OAuth 2.0 验证



作者:webabcd


介绍
背水一战 Windows 10 之 用户和账号

  • 数据账号的添加和管
  • OAuth 2.0 验证



示例
1、演示数据账号的添加和管理
UserAndAccount/DataAccount.xaml

<Page
    x:Class="Windows10.UserAndAccount.DataAccount"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Windows10.UserAndAccount"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="Transparent">
        <StackPanel Margin="10 0 10 10">

            <TextBlock Name="lblMsg" Margin="5" />
            
            <Button Name="buttonAdd" Content="新增一个数据账号" Margin="5" Click="buttonAdd_Click" />

        </StackPanel>
    </Grid>
</Page>

UserAndAccount/DataAccount.xaml.cs

/*
 * 演示数据账号的添加和管理
 * 
 * UserDataAccountManager - 数据账号管理器
 *     ShowAddAccountAsync() - 弹出账号添加界面
 *     ShowAccountSettingsAsync() - 弹出账号管理界面
 *     RequestStoreAsync() - 返回当前用户的数据账号存储区域
 *     GetForUser() - 返回指定用户的数据账号存储区域(通过返回的 UserDataAccountManagerForUser 对象的 RequestStoreAsync() 方法)
 *     
 * UserDataAccountStore - 数据账号存储区域
 *     FindAccountsAsync() - 返回所有的数据账号
 *     GetAccountAsync() - 返回指定的数据账号
 *     
 * UserDataAccount - 数据账号
 *     UserDisplayName - 用户名
 *     Id - 数据账号在本地设备上的唯一标识
 *     SaveAsync() - 保存
 *     DeleteAsync() - 删除
 *     ... 还有很多其他属性和方法
 *     
 *     
 * 注:根据使用的功能需要在 Package.appxmanifest 做相关配置
 * 1、用到 Windows.System.User 的话需要配置 <Capability Name="userAccountInformation" />
 * 2、还可能需要 <Capability Name="appointments" />, <Capability Name="contacts" />
 */

using System;
using System.Linq;
using System.Collections.Generic;
using Windows.ApplicationModel.UserDataAccounts;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Navigation;

namespace Windows10.UserAndAccount
{
    public sealed partial class DataAccount : Page
    {
        public DataAccount()
        {
            this.InitializeComponent();
        }

        protected async override void OnNavigatedTo(NavigationEventArgs e)
        {
            base.OnNavigatedTo(e);

            // 获取当前用户下的全部数据账号
            UserDataAccountStore store = await UserDataAccountManager.RequestStoreAsync(UserDataAccountStoreAccessType.AllAccountsReadOnly);
            IReadOnlyList<UserDataAccount> accounts = await store.FindAccountsAsync();
            lblMsg.Text += string.Join(",", accounts.Select(p => p.UserDisplayName));
            lblMsg.Text += Environment.NewLine;
        }

        private async void buttonAdd_Click(object sender, RoutedEventArgs e)
        {
            // 弹出账号添加界面,如果添加成功会返回新建的数据账号的在本地设备上的唯一标识
            string userDataAccountId = await UserDataAccountManager.ShowAddAccountAsync(UserDataAccountContentKinds.Email | UserDataAccountContentKinds.Appointment | UserDataAccountContentKinds.Contact);

            if (string.IsNullOrEmpty(userDataAccountId))
            {
                lblMsg.Text += "用户取消了或添加账号失败";
                lblMsg.Text += Environment.NewLine;
            }
            else
            {
                UserDataAccountStore store = await UserDataAccountManager.RequestStoreAsync(UserDataAccountStoreAccessType.AllAccountsReadOnly);
                if (store != null)
                {
                    // 通过数据账号在本地设备上的唯一标识来获取 UserDataAccount 对象
                    UserDataAccount account = await store.GetAccountAsync(userDataAccountId);
                    lblMsg.Text += "新增的数据账号:" + account.UserDisplayName;
                }
            }
        }
    }
}


2、演示如何开发一个基于 OAuth 2.0 验证的客户端 
UserAndAccount/OAuth20.xaml

<Page
    x:Class="Windows10.UserAndAccount.OAuth20"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Windows10.UserAndAccount"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="Transparent">
        <StackPanel Margin="10 0 10 10">

            <Button Name="buttonWeibo" Content="登录新浪微博,并返回登录用户好友最新发布的微博" Margin="5" Click="buttonWeibo_Click" />

            <TextBlock Name="lblMsg" TextWrapping="Wrap" Margin="5" />

        </StackPanel>
    </Grid>
</Page>

UserAndAccount/OAuth20.xaml.cs

/*
 * 演示如何开发一个基于 OAuth 2.0 验证的客户端 
 * 关于 OAuth 2.0 协议请参见:http://tools.ietf.org/html/draft-ietf-oauth-v2-20
 * 
 * WebAuthenticationBroker - 用于 OAuth 2.0 验证的第一步,可以将第三方 UI 无缝整合进 app
 *     AuthenticateAsync(WebAuthenticationOptions options, Uri requestUri, Uri callbackUri) - 请求 authorization code,返回一个 WebAuthenticationResult 类型的数据
 *
 * WebAuthenticationResult - 请求 authorization code(OAuth 2.0 验证的第一步)的结果
 *     ResponseData - 响应的数据         
 *     ResponseStatus - 响应的状态
 * 
 * 
 * 注:本例以微博开放平台为例
