I have create a Mobile App service with Azure. I have created a new custom controller as seen below.
[MobileAppController]
public class NewsController : ApiController
{
public ApiServices Services { get; set; }
// GET api/News
public async Task<IEnumerable<NewsItem>> Get()
{//returns some data}
}
Within Azure I have enabled authentication and set the options to Active Directory as seen below.
I'm trying to consume the API within a Xamarin iOS application.
I create a access token via Active Directory as seen below and this works and generates the token correctly.
public static class ServicePrincipal
{
static string authority = "https://login.microsoftonline.com/xxx";
static string clientId = "xxx";
static string clientSecret = "xx";
static string resource = "xx";
public static async Task<AuthenticationResult> GetS2SAccessTokenForProdMSA()
{
return await GetS2SAccessToken();
}
static async Task<AuthenticationResult> GetS2SAccessToken()
{
try
{
AdalInitializer.Initialize();
var clientCredential = new ClientCredential(clientId, clientSecret);
var context = new AuthenticationContext(authority, false);
var authenticationResult = await context.AcquireTokenAsync(
resource,
clientCredential);
return authenticationResult;
}
catch (Exception ex)
{
throw;
}
}
}
However when trying to consume the API i always get an unauthorized exception.
I have tried authenticating by passing the token to the custom API like this. This throws an unauthorized exception
var client = new MobileServiceClient("THE URL");
var authenticationResult = await ServicePrincipal.GetS2SAccessTokenForProdMSA();
var authHeader = new Dictionary<string, string> { { "Bearer", authenticationResult.AccessToken } };
var orderResult = await client.InvokeApiAsync("News", HttpMethod.Get, authHeader);
I also tried the following, which doesn't work either.
CurrentPlatform.Init();
var client = new MobileServiceClient("THE URL");
var authenticationResult = await ServicePrincipal.GetS2SAccessTokenForProdMSA();
JObject payload = new JObject();
payload["access_token"] = authenticationResult.AccessToken;
await client.LoginAsync(MobileServiceAuthenticationProvider.WindowsAzureActiveDirectory, payload);
Can you see any issues here, how do i pass though the authorization token?
