I want to get data from logedin users , so im searching in internet and found that i can use Azure AD Graph, or Microsoft Graph. So i Chose using Microsoft Graph and found this solution https://github.com/Azure-Samples/active-directory-xamarin-native-v2 and then im trying to implement with my azure b2c login so there some code that i change, here is some my code. This is my App.Cs
using Microsoft.Identity.Client;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Xamarin.Forms;
namespace UsingGraphApi
{
public partial class App : Application
{
public static PublicClientApplication AuthenticationClient { get; private set; }
// public static PublicClientApplication PCA = null;
//public static string ClientID = "a7d8cef0-4145-49b2-a91d-95c54051fa3f";
// public static string[] Scopes = { "User.Read" };
// public static string Username = string.Empty;
//public static UIParent UiParent = null;
public App()
{
InitializeComponent();
AuthenticationClient = new PublicClientApplication(Constants.ApplicationID);
MainPage = new NavigationPage(new MainPage());
}
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
}
}
}
this is my Constant.Cs
namespace UsingGraphApi
{
public static class Constants
{
public static string ApplicationID = "c2026789-5e43-4d25-acc9-e00768d4b0b4";
//public static string[] Scopes = { ApplicationID };
public static string[] Scopes = { "User.Read" };
public static string SignUpSignInPolicy = "B2C_1_signin";
public static string ResetPasswordPolicy = "b2c_1_reset";
public static string Authority = "https://login.microsoftonline.com/kgvaluecard.onmicrosoft.com/";
}
}
and here is my MainPage.Cs
using Microsoft.Identity.Client;
using Newtonsoft.Json.Linq;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
using Xamarin.Forms;
namespace UsingGraphApi
{
public partial class MainPage : ContentPage
{
public MainPage()
{
InitializeComponent();
}
protected override async void OnAppearing()
{
// let's see if we have a user in our belly already
try
{
var result = await App.AuthenticationClient.AcquireTokenSilentAsync(Constants.Scopes);
RefreshUserData(result.Token);
//btnSignInSignOut.Text = "Sign out";
await DisplayAlert("OK", "OK", "OK");
}
catch
{
// doesn't matter, we go in interactive more
// btnSignInSignOut.Text = "Sign in";
}
}
async void OnSignInSignOut(object sender, EventArgs e)
{
try
{
var result = await App.AuthenticationClient.AcquireTokenAsync(
Constants.Scopes,
string.Empty,
UiOptions.SelectAccount,
string.Empty,
null,
Constants.Authority,
Constants.SignUpSignInPolicy);
RefreshUserData(result.Token);
//btnSignInSignOut.Text = "Sign out";
}
catch (Exception )
{
//
}
}
public async void RefreshUserData(string Token)
{
//get data from API
HttpClient client = new HttpClient();
HttpRequestMessage message = new HttpRequestMessage(HttpMethod.Get, "https://graph.microsoft.com/v1.0/me");
message.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("bearer", Token);
HttpResponseMessage response = await client.SendAsync(message);
string responseString = await response.Content.ReadAsStringAsync();
if (response.IsSuccessStatusCode)
{
JObject user = JObject.Parse(responseString);
slUser.IsVisible = true;
lblDisplayName.Text = user["displayName"].ToString();
lblGivenName.Text = user["givenName"].ToString();
lblId.Text = user["id"].ToString();
lblSurname.Text = user["mail"].ToString();
lblUserPrincipalName.Text = user["userPrincipalName"].ToString();
// just in case
btnSignInSignOut.Text = "Sign out";
}
else
{
//DisplayAlert("Something went wrong with the API call", responseString, "Dismiss");
}
}
}
}
the application is can be deployed and run well but the problem is i dont get the users information, is there any wrong with my code that i shouldnt change and by the way here is my MainPage.Xaml
