    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" />

        {
            public DataAccount()

    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: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
