介绍
背水一战 Windows 10 之 用户和账号
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:///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:///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
