作者：webabcd
介绍
重新想象 Windows 8 Store Apps 之 微软账号
- 获取微软账号的用户相关的信息
- 获取或设置微软账号的图片和视频
- 微软账号的验证，和相关信息的获取
示例
1、演示如何获取微软账号的用户相关的信息
Account/AccountInfo.xaml
<Page
x:Class="XamlDemo.Account.AccountInfo"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:XamlDemo.Account"
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="120 0 0 0"> <TextBlock Name="lblMsg" FontSize="14.667" /> </StackPanel>
</Grid>
</Page>
Account/AccountInfo.xaml.cs
/*
* 演示如何获取微软账号的用户相关的信息
*/ using System;
using Windows.System.UserProfile;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Navigation; namespace XamlDemo.Account
{
public sealed partial class AccountInfo : Page
{
public AccountInfo()
{
this.InitializeComponent();
} protected async override void OnNavigatedTo(NavigationEventArgs e)
{
if (UserInformation.NameAccessAllowed) // 是否允许访问用户名
{
// 获取用于显示的名称
lblMsg.Text = "display name: " + await UserInformation.GetDisplayNameAsync();
lblMsg.Text += Environment.NewLine; // 获取 first name
lblMsg.Text += "first name: " + await UserInformation.GetFirstNameAsync();
lblMsg.Text += Environment.NewLine; // 获取 last name
lblMsg.Text += "last name: " + await UserInformation.GetLastNameAsync();
lblMsg.Text += Environment.NewLine;
} // 如果需要获取 GetDomainNameAsync(), GetPrincipalNameAsync(), GetSessionInitiationProtocolUriAsync() 等信息
// 则需要在 Package.appxmanifest 中增加配置 <Capability Name="enterpriseAuthentication" />，且必须使用公司账号上传 app
}
}
}
2、演示如何获取或设置微软账号的图片和视频
Account/AccountPicture.xaml
<Page
x:Class="XamlDemo.Account.AccountPicture"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:XamlDemo.Account"
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="120 0 0 0"> <StackPanel Orientation="Horizontal">
<Button x:Name="btnSetImage" Content="设置当前微软账号的图片（可以分别指定小图，大图，视频）" Click="btnSetImage_Click_1" />
</StackPanel> <StackPanel Orientation="Horizontal" Margin="0 10 0 0">
<Image x:Name="imgSmall" Width="96" Height="96" HorizontalAlignment="Left" />
<Image x:Name="imgLarge" Width="448" Height="448" Margin="10 0 0 0" HorizontalAlignment="Left" />
<MediaElement x:Name="mediaElement" Width="200" Height="200" Margin="10 0 0 0" HorizontalAlignment="Left" />
</StackPanel> </StackPanel>
</Grid>
</Page>
Account/AccountPicture.xaml.cs
/*
* 演示如何获取或设置微软账号的图片和视频
*/ using System;
using Windows.Storage;
using Windows.Storage.Pickers;
using Windows.Storage.Streams;
using Windows.System.UserProfile;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Media.Imaging;
using Windows.UI.Xaml.Navigation;
using XamlDemo.Common; namespace XamlDemo.Account
{
public sealed partial class AccountPicture : Page
{
public AccountPicture()
{
this.InitializeComponent();
} protected override void OnNavigatedTo(NavigationEventArgs e)
{
GetSmallImage();
GetLargeImage();
GetVideo(); // 当微软账号的图片或视频发生变化时触发的事件
UserInformation.AccountPictureChanged += PictureChanged;
} protected override void OnNavigatedFrom(NavigationEventArgs e)
{
UserInformation.AccountPictureChanged -= PictureChanged;
} private void PictureChanged(object sender, object e)
{
GetSmallImage();
GetLargeImage();
GetVideo();
} // 获取小图片
private async void GetSmallImage()
{
// UserInformation.GetAccountPicture(AccountPictureKind.SmallImage) - 获取当前微软账号的小图片
StorageFile image = UserInformation.GetAccountPicture(AccountPictureKind.SmallImage) as StorageFile;
if (image != null)
{
try
{
IRandomAccessStream imageStream = await image.OpenReadAsync();
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.SetSource(imageStream);
imgSmall.Source = bitmapImage;
}
finally { }
}
} // 获取大图片
private async void GetLargeImage()
{
// UserInformation.GetAccountPicture(AccountPictureKind.LargeImage) - 获取当前微软账号的大图片
StorageFile image = UserInformation.GetAccountPicture(AccountPictureKind.LargeImage) as StorageFile;
if (image != null)
{
try
{
IRandomAccessStream imageStream = await image.OpenReadAsync();
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.SetSource(imageStream);
imgLarge.Source = bitmapImage;
}
finally { }
}
} // 获取视频
private async void GetVideo()
{
// UserInformation.GetAccountPicture(AccountPictureKind.Video) - 获取当前微软账号的视频
StorageFile video = UserInformation.GetAccountPicture(AccountPictureKind.Video) as StorageFile;
if (video != null)
{
try
{
IRandomAccessStream videoStream = await video.OpenAsync(FileAccessMode.Read);
mediaElement.SetSource(videoStream, "video/mp4");
}
finally { }
}
} // 设置图片
private async void btnSetImage_Click_1(object sender, RoutedEventArgs e)
{
if (Helper.EnsureUnsnapped())
{
FileOpenPicker imagePicker = new FileOpenPicker
{
ViewMode = PickerViewMode.Thumbnail,
SuggestedStartLocation = PickerLocationId.PicturesLibrary,
FileTypeFilter = { ".jpg", ".jpeg", ".png", ".bmp" }
}; StorageFile imageFile = await imagePicker.PickSingleFileAsync();
if (imageFile != null)
{
// UserInformation.SetAccountPicturesAsync() - 设置微软账号的图片和视频（可以分别指定：小图片，大图片，视频）
SetAccountPictureResult result = await UserInformation.SetAccountPicturesAsync(null, imageFile, null);
if (result == SetAccountPictureResult.Success)
{ }
}
}
}
}
}
3、演示微软账号的验证，和相关信息的获取
Account/AccountAuthorization.xaml
<Page
x:Class="XamlDemo.Account.AccountAuthorization"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:XamlDemo.Account"
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="120 0 0 0"> <TextBlock Name="lblMsg" FontSize="14.667" />
<Button Name="btnSignIn" Content="登录" Margin="0 10 0 0" Click="btnSignIn_Click_1" />
<Button Name="btnSignOut" Content="注销" Margin="0 10 0 0" Click="btnSignOut_Click_1" /> </StackPanel>
</Grid>
</Page>
Account/AccountAuthorization.xaml.cs
/*

*/ using System;
using System.Collections.Generic;
using Windows.Security.Authentication.OnlineId;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls; namespace XamlDemo.Account
{
public sealed partial class AccountAuthorization : Page
{
// OnlineIdAuthenticator - 用于身份验证，以及信息获取
private OnlineIdAuthenticator _authenticator; public AccountAuthorization()

lblMsg.Text += "登录中";
lblMsg.Text += Environment.NewLine; try

var targetArray = new List<OnlineIdServiceTicketRequest>();
targetArray.Add(new OnlineIdServiceTicketRequest("wl.basic wl.contacts_photos wl.calendars", "DELEGATION")); /*
* OnlineIdAuthenticator.AuthenticateUserAsync() - 登录
* CredentialPromptType.DoNotPrompt - 不显示登录 UI（可能会导致无法登录）

*/
var result = await _authenticator.AuthenticateUserAsync(targetArray, CredentialPromptType.PromptIfNeeded);
if (result.Tickets[].Value != string.Empty)
{
lblMsg.Text += "已登录";
lblMsg.Text += Environment.NewLine; // 获取 token （此 token 可以通过 rest 方式访问 wl.basic wl.contacts_photos wl.calendars 信息）

}
else
{
lblMsg.Text += "未得到 token ，errorCode: " + result.Tickets[].ErrorCode.ToString();
lblMsg.Text += Environment.NewLine;
}
}
catch (Exception ex)
{
lblMsg.Text += ex.ToString();
lblMsg.Text += Environment.NewLine;
}
} private async void btnSignOut_Click_1(object sender, RoutedEventArgs e)
{
lblMsg.Text += "注销中";
