经过一周的研究可与 Azure AD B2C 一起使用 Xamarin 以 Android 平台（而不是 Xamarin.Forms）为目标的身份验证原理后，我终于寻求一些建议。
我有一个带有“登录”按钮的活动，我想通过按钮的触摸事件登录到 Azure。理想情况下，我希望在登录步骤完成后收到令牌。
这是我到目前为止的代码：
public class MainActivity : Activity
{
public TaskCompletionSource<bool> ActivityResult { get; set; }
public const int LocationActivityResult = 110;
private static string AadInstance = "https://login.microsoftonline.com/{0}.onmicrosoft.com/";
private PublicClientApplication _publicClientApplication;
private string _authority;
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
//partie pour le sign in
EditText editTextEmail = FindViewById<EditText>(Resource.Id.editTextEmail);
EditText editTextPassword = FindViewById<EditText>(Resource.Id.editTextPassword);
Button signIn = FindViewById<Button>(Resource.Id.buttonSignIn);
signIn.Click += async (sender, e) =>
{
ConnectivityManager connectivityManager = (ConnectivityManager)GetSystemService(ConnectivityService);
NetworkInfo networkInfo = connectivityManager.ActiveNetworkInfo;
if (networkInfo == null)
{
Toast.MakeText(this, "Aucune connexion internet", ToastLength.Short).Show();
Intent intent = new Intent(this.ApplicationContext, typeof(NotInternetActivity));
intent.SetFlags(ActivityFlags.NewTask);
StartActivity(intent);
}
else
{
/////essai pour la connexion
_authority = string.Format(AadInstance, _azureSettings.Tenant);
_publicClientApplication = new PublicClientApplication(
_authority,
_azureSettings.ClientId
);
await AcquireTokenAsync();
/////passe sur la nouvelle actvité
Intent intent = new Intent(this.ApplicationContext, typeof(PlantsActivity));
intent.SetFlags(ActivityFlags.NewTask);
StartActivity(intent);
}
};
}
Authentication _azureSettings = new Authentication
{
ClientId = "ClientId",
ForgotPasswordPolicy = "ForgotPasswordPolicy",
SignInOrSignUpPolicy = "SignInOrSignUpPolicy",
Tenant = "Tenant"
};
protected override void OnActivityResult(int requestCode, [GeneratedEnum] Result resultCode, Intent data)
{
base.OnActivityResult(requestCode, resultCode, data);
if (requestCode.Equals(LocationActivityResult))
{
if (CrossGeolocator.Current.IsGeolocationEnabled)
this.ActivityResult.TrySetResult(true);
else
this.ActivityResult.TrySetResult(false);
}
else
{
AuthenticationAgentContinuationHelper.SetAuthenticationAgentContinuationEventArgs(requestCode, resultCode, data);
}
}
public class Authentication
{
public string Tenant { get; set; }
public string ClientId { get; set; }
public string SignInOrSignUpPolicy { get; set; }
public string ForgotPasswordPolicy { get; set; }
}
public Task<AuthenticationResult> AcquireTokenSilentAsync()
{
string[] scopes = { _azureSettings.ClientId };
var res = _publicClientApplication.AcquireTokenSilentAsync(scopes, "", _authority, _azureSettings.SignInOrSignUpPolicy, false);
return _publicClientApplication.AcquireTokenSilentAsync(scopes, "", _authority, _azureSettings.SignInOrSignUpPolicy, false);
}
public async Task<AuthenticationResult> AcquireTokenAsync()
{
string[] scopes = { _azureSettings.ClientId };
return await _publicClientApplication.AcquireTokenAsync(scopes, "", UiOptions.SelectAccount, string.Empty, null, _authority, _azureSettings.SignInOrSignUpPolicy);
}
}
我现在已将所有内容放在同一类中，只是为了测试结果。您可以给我提供的任何示例或您也可以指出我的有关 Xamarin.Android 的任何文档都会非常有帮助。
提前致谢。
