azure - 在 Xamarin Forms 中更改 Azure AD B2C 密码的方法

Question

我很难在 Xamarin 表单中更改密码方法。我尝试使用:

https://graph.windows.net/me/changePassword?api-version=1.6

很难找到使其在 Xamarin 表单中工作的引用，这就是我到目前为止所拥有的。

这是我的模型:

using Newtonsoft.Json;

namespace KGVC.Models
{
    public class GraphModel
    {
        const  string ChangePassword = "https://graph.windows.net/me/changePassword?api-version=1.6";
        [JsonProperty("currentPassword")]
        public static string  currentPassword { get; set; }

        [JsonProperty("newPassword")]
        public static string newPassword { get; set; }


    }
}

...这是我更改密码的用户界面:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="KGVC.Views.LogoutPage">
    <StackLayout HorizontalOptions="Center" VerticalOptions="Center">
        <Button x:Name="logoutButton" Text="Logout" Clicked="OnLogoutButtonClicked" />
        <Label x:Name="messageLabel" FontSize="Medium" />
        <Label Text="Change Password" FontSize="Large" HorizontalOptions="Center" Margin="5"/>
        <Label Text="Current Password"  VerticalOptions="Center"  Margin="5"/>
        <Entry x:Name="currentPassword"/>
        <Label Text="New Password"  VerticalOptions="Center"/>
        <Entry x:Name="newPassword"/>
        <Button Text="Change Password" Clicked="ChangePasswordClicked" Margin="20"/>
    </StackLayout>
</ContentPage>

...这是迄今为止我的方法:

using System.Linq;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;
using KGVC.Models;
using Microsoft.Identity.Client;
using Xamarin.Forms;
using Xamarin.Forms.Xaml;

namespace KGVC.Views
{
    [XamlCompilation(XamlCompilationOptions.Compile)]
    public partial class LogoutPage : ContentPage
    {

        AuthenticationResult authenticationResult;

        public LogoutPage(AuthenticationResult result)
        {
            InitializeComponent();
            authenticationResult = result;
        }

        protected override void OnAppearing()
        {
            if (authenticationResult != null)
            {
                if (authenticationResult.User.Name != "unknown")
                {
                    messageLabel.Text = string.Format("Welcome {0}", authenticationResult.User.Name);
                }
                else
                {
                    messageLabel.Text = string.Format("UserId: {0}", authenticationResult.User.UniqueId);
                }
            }

            base.OnAppearing();
        }
        public  void ChangePasswordClicked(object sender, EventArgs e)
        {
            var client = new HttpClient();
            var request = new HttpRequestMessage(HttpMethod.Post,
                "https://graph.windows.net/me/changePassword?api-version=1.6");
          //  request.Headers.Authorization =
            //  new AuthenticationHeaderValue("Bearer", authResult.AccessToken);
            //var response = await client.SendAsync(request);
            //var content = await response.Content.ReadAsStringAsync();
        }

        async void OnLogoutButtonClicked(object sender, EventArgs e)
        {
            App.AuthenticationClient.UserTokenCache.Clear(Constants.ApplicationID);
            await Navigation.PopAsync();
        }


    }
}

结果是来 self 的登录 View 模型的参数，这是我的 App.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using KGVC.Models;
using KGVC.Views;
using Microsoft.Identity.Client;
using Microsoft.Practices.ServiceLocation;
using Microsoft.Practices.Unity;
using Xamarin.Forms;

namespace KGVC
{
    public partial class App : Application
    {

        public static PublicClientApplication AuthenticationClient { get; private set; }
        public App()
        {
            InitializeComponent();
            UnityContainer unityContainer = new UnityContainer();
            //  unityContainer.RegisterType<LoginService>();
            ServiceLocator.SetLocatorProvider(() => new UnityServiceLocator(unityContainer));
            AuthenticationClient = new PublicClientApplication(Constants.ApplicationID);
            MainPage = new NavigationPage(new LoginPage());
        }

        protected override void OnStart()
        {
            // Handle when your app starts
        }

        protected override void OnSleep()
        {
            // Handle when your app sleeps
        }

        protected override void OnResume()
        {
            // Handle when your app resumes
        }
    }
}

是否有任何我可以查找的引用资料或 GitHub 文件来解决我的问题，以及我应该在我的方法中添加什么内容还是我需要其他内容？

嘿，看起来您试图直接在图形 API 上更改密码，我认为这是不允许的，通过 B2C 使用重置密码策略，它将为您处理所有事情
