从Azure B2C访问Microsoft Graph API

Question

我有一个Azure广告B2C租户，有一个正在运行的应用程序。它被配置为仅使用Azure AD和Microsoft帐户登录。此应用程序由App Center Auth使用。

// Sign-in succeeded, UserInformation is not null.
var userInfo = await Auth.SignInAsync();

// Get tokens. They are not null.
var idToken = userInfo.IdToken;
var accessToken = userInfo.AccessToken;

var graphAPIEndpoint = "https://graph.microsoft.com/v1.0/me";
var scopes = new[] { "user.read" };

var client = new HttpClient();

var request = new HttpRequestMessage(HttpMethod.Get, graphAPIEndpoint + "/photo/$value");
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
var response = await client.SendAsync(request);
var image = await response.Content.ReadAsByteArrayAsync();

UserImage.Source = ImageSource.FromStream(() => new MemoryStream(image));

Answer 1

就像@juunas所说的，从今天起，你需要使用AAD Graph API来访问Azure AD B2C租户，这与微软的Graph API是不同的。
