I am setting a custom state paramter value in OnRedirectToIdentityProvider and able to access it in OnMessageReceived. This custom state value can be accessed in MVC Controller but the value is in an encrypted format. How can I access this in a decrypted manner in Controller. Below is my code:
private static Task OnRedirectToIdentityProvider(RedirectToIdentityProviderNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> notification)
{
var stateQueryString = notification.ProtocolMessage.State.Split('=');
var protectedState = stateQueryString[1];
var state = notification.Options.StateDataFormat.Unprotect(protectedState);
state.Dictionary.Add("stateUTName", "chandigarh");
notification.ProtocolMessage.State = stateQueryString[0] + "=" + notification.Options.StateDataFormat.Protect(state);
return Task.FromResult(0);
}
private Task OnMessageReceived(MessageReceivedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> notification)
{
string mycustomparameter;
var protectedState = notification.ProtocolMessage.State.Split('=')[1];
var state = notification.Options.StateDataFormat.Unprotect(protectedState);
state.Dictionary.TryGetValue("stateUTName", out mycustomparameter);
return Task.FromResult(0);
}
The Value obtained in Controller looks like: OpenIdConnect.AuthenticationProperties=CfijlEY2jd9Jv4J7i5qy0K1ZZ5x2FR5ZraXo2dDVWl-a2RppU46kHpnoZe2mLJ2qpXFlpMRnu1nxKPYXepR4KwnhxAll88xSZmK41BsfIVkmCa34dfHK_RdBwRZW3cwHqIsD1N4Cqmr655xjK-gSr53zetwZeUq0UX-nBTpz1TZTgc64-8JOLiXPEVlvLM6KYZNQYGBkoCNCNCV_GEbgx0U1QuGPuHxglJD3SGbKF9bo_OjhI6L-U-hPbalY0Fa-

I have built a Blazor Server App with Azure AD authentication. This server app access a web api written in net core and sends the JWT token to that api. Everything is working, data is gathered, page is displayed accordingly.
The problem is: after some time, when user interacts with some menu option in UI, nothing else is returned from webapi. After some tests I found out that the token has expired, then when it is sent to web api, it is not working. But the AuthenticationState remains same, like it is authenticated and valid irrespective the token is expired.
Thus, I have been trying some suggestions like : Client side Blazor authentication token expired on server side. Actually it is the closest solution I got.
But the problem is that, after implemented a CustomAuthenticationStateProvider class, even after injected it, the default AuthenticationStateProvider of the app remains like ServerAuthenticationStateProvider and not the CustomAuthenticationStateProvider I have implemented. This is part of my code:
public class CustomAuthenticationStateProvider : AuthenticationStateProvider
{
private readonly IConfiguration _configuration;
private readonly ITokenAcquisition _tokenAcquisition;
public CustomAuthenticationStateProvider(IConfiguration configuration, ITokenAcquisition tokenAcquisition)
{
_configuration = configuration;
_tokenAcquisition = tokenAcquisition;
}
public override async Task<AuthenticationState> GetAuthenticationStateAsync()
{
var apiScope = _configuration["DownloadApiStream:Scope"];
var anonymousState = new AuthenticationState(new ClaimsPrincipal(new ClaimsIdentity()));
string savedToken = string.Empty;
try
{
savedToken = await _tokenAcquisition.GetAccessTokenForUserAsync(new[] { apiScope });
}
catch (MsalUiRequiredException)
{
savedToken = string.Empty;
}
catch (Exception)
{
savedToken = string.Empty;
}
if (string.IsNullOrWhiteSpace(savedToken))
{
return anonymousState;
}
var claims = ParseClaimsFromJwt(savedToken).ToList();
var expiry = claims.Where(claim => claim.Type.Equals("exp")).FirstOrDefault();
if (expiry == null)
return anonymousState;
// The exp field is in Unix time
var datetime = DateTimeOffset.FromUnixTimeSeconds(long.Parse(expiry.Value));
if (datetime.UtcDateTime <= DateTime.UtcNow)
return anonymousState;
return new AuthenticationState(new ClaimsPrincipal(new ClaimsIdentity(claims, "jwt")));
}
public void NotifyExpiredToken()
{
var anonymousUser = new ClaimsPrincipal(new ClaimsIdentity());
var authState = Task.FromResult(new AuthenticationState(anonymousUser));
NotifyAuthenticationStateChanged(authState);
}
private IEnumerable<Claim> ParseClaimsFromJwt(string jwt)
{
var claims = new List<Claim>();
var payload = jwt.Split('.')[1];
var jsonBytes = ParseBase64WithoutPadding(payload);
var keyValuePairs = JsonSerializer.Deserialize<Dictionary<string, object>>(jsonBytes);
keyValuePairs.TryGetValue(ClaimTypes.Role, out object roles);
if (roles != null)
{
if (roles.ToString().Trim().StartsWith("["))
{
var parsedRoles = JsonSerializer.Deserialize<string[]>(roles.ToString());
foreach (var parsedRole in parsedRoles)
{
claims.Add(new Claim(ClaimTypes.Role, parsedRole));
}
}
else
{
claims.Add(new Claim(ClaimTypes.Role, roles.ToString()));
}
keyValuePairs.Remove(ClaimTypes.Role);
}
claims.AddRange(keyValuePairs.Select(kvp => new Claim(kvp.Key, kvp.Value.ToString())));
return claims;
}
private byte[] ParseBase64WithoutPadding(string base64)
{
switch (base64.Length % 4)
{
case 2: base64 += "=="; break;
case 3: base64 += "="; break;
}
return Convert.FromBase64String(base64);
}
}
This is my Program.cs where I added the services :
builder.Services.AddScoped<CustomAuthenticationStateProvider>();
builder.Services.AddScoped<AuthenticationStateProvider>(provider => provider.GetRequiredService<CustomAuthenticationStateProvider>());
Here in the MainLayou.razor, I inject the service and try to use it :
#inject CustomAuthenticationStateProvider authenticationStateProvider;
protected async override Task OnInitializedAsync()
{
var authState = await authenticationStateProvider.GetAuthenticationStateAsync();
if (authState.User?.Identity == null || !authState.User.Identity.IsAuthenticated)
{
authenticationStateProvider.NotifyExpiredToken();
}
await base.OnInitializedAsync();
}
The problem comes up here, because the authenticationStateProvider is not an instance of the CustomAuthenticationStateProvider , but the instance of ServerAuthenticationStateProvider. It is like AuthenticationStateProvider was not replaced by the custom implementation, therefore I can't use the NotifyAuthenticationStateChanged and inform the CascadingAuthenticationState that it was changed.
If anyone has already been thru this or have any suggestion, it would be appreciated.
Actually I just wanna to change authentication state to not authenticated. So user will be pushed to login again using Azure AD.
Thanks
In my old non-OWIN APIs, I use a MessageHanlder to log all HttpRequests and HttpResponses. Here is the MessageHandler:
public class MessageHandler : DelegatingHandler
{
private static readonly ILog RequestApiLogger = LogManager.GetLogger("RequestApiPacketLogger");
private static readonly ILog ResponseApiLogger = LogManager.GetLogger("ResponseApiPacketLogger");
protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
var correlationId = Guid.NewGuid();
RequestApiLogger.LogHttpRequest(request, correlationId);
return await base.SendAsync(request, cancellationToken).ContinueWith(
task =>
{
var response = task.Result;
response.Headers.Add("http-tracking-id", correlationId.ToString("D"));
ResponseApiLogger.LogHttpResponse(response, correlationId);
return response;
}, cancellationToken);
}
}
However, in my newer projects I could write custom OWIN middleware to do something similar using the OwinContext like this:
//use an alias for the OWIN AppFunc
using AppFunc = Func<IDictionary<string, object>, Task>;
public class LoggingMiddleware
{
private readonly AppFunc _next;
public LoggingMiddleware(AppFunc next)
{
_next = next;
}
public async Task Invoke(IDictionary<string, object> environment)
{
IOwinContext context = new OwinContext(environment);
// Get the identity
var identity = (context.Request.User != null && context.Request.User.Identity.IsAuthenticated)
? context.Request.User.Identity.Name
: "(anonymous)";
// Buffer the request (body is a string, we can use this to log the request later
var requestBody = new StreamReader(context.Request.Body).ReadToEnd();
var requestData = Encoding.UTF8.GetBytes(requestBody);
context.Request.Body = new MemoryStream(requestData);
var apiPacket = new ApiPacket
{
CallerIdentity = identity,
Request = requestBody,
RequestLength = context.Request.Body.Length
};
// Buffer the response
var responseBuffer = new MemoryStream();
var responseStream = context.Response.Body;
context.Response.Body = responseBuffer;
// add the "http-tracking-id" response header so the user can correlate back to this entry
var responseHeaders = (IDictionary<string, string[]>)environment["owin.ResponseHeaders"];
responseHeaders["http-tracking-id"] = new[] { apiPacket.TrackingId.ToString("d") };
await _next.Invoke(environment);
responseBuffer.Seek(0, SeekOrigin.Begin);
var reader = new StreamReader(responseBuffer);
apiPacket.Response = await reader.ReadToEndAsync();
apiPacket.ResponseLength = context.Response.ContentLength ?? 0;
WriteRequestHeaders(context.Request, apiPacket);
WriteResponseHeaders(context.Response, apiPacket);
// You need to do this so that the response we buffered is flushed out to the client application.
responseBuffer.Seek(0, SeekOrigin.Begin);
await responseBuffer.CopyToAsync(responseStream);
//TODO: persist the ApiPacket in the database
}
private static void WriteRequestHeaders(IOwinRequest request, ApiPacket packet)
{
packet.Verb = request.Method;
packet.RequestUri = request.Uri;
packet.RequestHeaders = "{\r\n" + string.Join(Environment.NewLine, request.Headers.Select(kv => "\t" + kv.Key + "=" + string.Join(",", kv.Value))) + "\r\n}";
}
private static void WriteResponseHeaders(IOwinResponse response, ApiPacket packet)
{
packet.StatusCode = response.StatusCode;
packet.ReasonPhrase = response.ReasonPhrase;
packet.ResponseHeaders = "{\r\n" + string.Join(Environment.NewLine, response.Headers.Select(kv => "\t" + kv.Key + "=" + string.Join(",", kv.Value))) + "\r\n}";
}
}
I'm using log4net to write the information to a SQL2012 database. Both ways accomplish my goal. However, I'm looking for a reason to use one method over the other. Should I use custom OWIN middleware OR a MessageHandler, and why? Thanks in advance.
Since you already have the MessageHandler implementations, I would recommend using that until you have a reason otherwise.
However, off the top of my head one valid reason to move logging to an OwinMiddleware would be if you have other OwinMiddleware components that require (or would benefit from) that logging functionality (assuming that you are using WebApi whereby the MessageHandlers will run after all of the OwinMiddleware in the request-pipeline).
Looks like I will be using OWIN middleware. I found that inside the MessageHandler the Principal.IIdentity has not yet been resolved. For example, if I put breakpoints in my message handler, an API controller's constructor, and in the API method, this is what I see (in order).
Using Message Handler
In MessageHandler > Principal.IIdentity not yet resolved.
In API controller's constructor > Principal.IIDentity not yet resolved.
In API controller's GET method, the Principal.IIdentity is finally resolved.
Thus, I can't pull out and log the authorized user's id in the MessageHandler.
However, when using the OWIN middleware, the Principal.IIdentity IS resolved there, so I can write the userId to my log table at that point. This is why I've decided to use the middleware.
Maybe someone can provide some clarity as to when the IIDentity is set in an API project though.
I structured my project into multiple mobile services, grouped by the application type eg:
my-core.azure-mobile.net (user, device)
my-app-A.azure-mobile.net (sales, order, invoice)
my-app-B.azure-mobile.net (inventory & parts)
I'm using custom authentication for all my services, and I implemented my own SSO by setting the same master key to all 3 services.
Things went well when I tested using REST client, eg. user who "logged in" via custom api at my-core.azure-mobile.net is able to use the returned JWT token to access restricted API of the other mobile services.
However, in my xamarin project, only the first (note, in sequence of creation) MobileServiceClient object is working properly (eg. returning results from given table). The client object are created using their own url and key respectively, and stored in a dictionary.
If i created client object for app-A then only create for app-B, I will be able to perform CRUD+Sync on sales/order/invoice entity, while CRUD+Sync operation on inventory/part entity will just hang there. The situation is inverse if I swap the client object creation order.
I wonder if there is any internal static variables used within the MobileServiceClient which caused such behavior, or it is a valid bug ?
=== code snippet ===
public class AzureService
{
IDictionary<String, MobileServiceClient> services = new Dictionary<String, MobileServiceClient>();
public MobileServiceClient Init (String key, String applicationURL, String applicationKey)
{
return services[key] = new MobileServiceClient (applicationURL, applicationKey);
}
public MobileServiceClient Get(String key)
{
return services [key];
}
public void InitSyncContext(MobileServiceSQLiteStore offlineStore)
{
// Uses the default conflict handler, which fails on conflict
// To use a different conflict handler, pass a parameter to InitializeAsync.
// For more details, see http://go.microsoft.com/fwlink/?LinkId=521416
var syncHandler = new MobileServiceSyncHandler ();
foreach(var client in services) {
client.Value.SyncContext.InitializeAsync (offlineStore, syncHandler);
}
}
public void SetAuthenticationToken(String uid, String token)
{
var user = new MobileServiceUser(uid);
foreach(var client in services) {
client.Value.CurrentUser = user;
client.Value.CurrentUser.MobileServiceAuthenticationToken = token;
}
}
public void ClearAuthenticationToken()
{
foreach(var client in services) {
client.Value.CurrentUser = null;
}
}
}
=== more code ===
public class DatabaseService
{
public static MobileServiceSQLiteStore LocalStore = null;
public static string Path { get; set; }
public static ISet<IEntityMappingProvider> Providers = new HashSet<IEntityMappingProvider> ();
public static void Init (String dbPath)
{
LocalStore = new MobileServiceSQLiteStore(dbPath);
foreach(var provider in Providers) {
var types = provider.GetSupportedTypes ();
foreach(var t in types) {
JObject item = null;
// omitted detail to create JObject using reflection on given type
LocalStore.DefineTable(tableName, item);
}
}
}
}
=== still code ===

}

return Task.FromResult(theCollection);
}

AzureService.Instance.InitSyncContext (DatabaseService.LocalStore);
AzureService.Instance.SetAuthenticationToken("AAA", "BBB");
UserService.Instance.ServiceClient = coreSvc;
PartService.Instance.ServiceClient = invSvc;
var x = await UserService.GetAll(); // this will work
var y = await PartService.GetAll(); // but not this
}
It's ok to use multiple MobileServiceClient objects, but not with the same local database. The offline sync feature uses a particular system tables to keep track of table operations and errors, and it is not supported to use the same local store across multiple sync contexts.
I'm not totally sure why it is hanging in your test, but it's possible that there is a lock on the local database file and the other sync context is waiting to get access.
You should instead use different local database files for each service and doing push and pull on each sync context. With your particular example, you just need to move LocalStore out of DatabaseService and into a dictionary in AzureService.
In general, it seems like an unusual design to use multiple services from the same client app. Is there a particular reason that the services need to be separated from each other?
ConfigurationManager has AppSettings name-value collection but CloudConfigurationManager has only GetSetting(string) method where you can get the config settings 1 by 1 if you know the key.
Is there a way to get the whole config of the role runtime?
The root cause is that I want to make strong typed configuration in order to abstract it away and make my code more testable. Using CloudConfigurationManager directly is implicit dependency which I want to remove with an abstraction which I want to stub in tests. So I find this practical. Which brings me to my question.
I do not want to use library like fx.configuration.azure because I will have to carry its dependency altogether because it requires inheritance of a base class.
AFAIK, there's no direct method available which will give you this information.
However there's a workaround that you can use. It involves making use of Service Management API's Get Deployment operation. This operation will return an XML and one of the element there is Configuration which contains your service configuration file in Base64 encoded format. You can read this element, convert it into string and parse the XML to get to ConfigurationSettings elements. It's child elements contains all the settings.
For this, you could either write your own wrapper over Service Management REST API or make use of Azure Management Library.
UPDATE
So here's a sample code for listing all configuration settings from Service Configuration File using Azure Management Library. It's a simple console app hacked together in very short amount of time thus has a lot of scope of improvement :). For management certificate, I have used the data from Publish Setting File.
You just have to install Azure Management Library Nuget Package in your console application:
Install-Package Microsoft.WindowsAzure.Management.Libraries
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.WindowsAzure;
using Microsoft.WindowsAzure.Management.Compute;
using System.Security.Cryptography.X509Certificates;
using System.Xml.Linq;
namespace ReadConfigurationSettingsUsingAzureManagementLibrary
{
class Program
{
static string subscriptionId = "<subscription-id>";
static string managementCertContents = "<Base64 Encoded Management Certificate String from Publish Setting File>";//Certificate string from Azure Publish Settings file
static string cloudServiceName = "<your cloud service name>";
static string ns = "http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration";
static void Main(string[] args)
{
var managementCetificate = new X509Certificate2(Convert.FromBase64String(managementCertContents));
var credentials = new CertificateCloudCredentials(subscriptionId, managementCetificate);
var computeManagementClient = new ComputeManagementClient(credentials);
var response = computeManagementClient.HostedServices.GetDetailed(cloudServiceName);
var deployment = response.Deployments.FirstOrDefault(d => d.DeploymentSlot == Microsoft.WindowsAzure.Management.Compute.Models.DeploymentSlot.Production);
if (deployment != null)
{
var config = deployment.Configuration;
XElement configXml = XElement.Parse(config);
var roles = configXml.Descendants(XName.Get("Role", ns));
foreach (var role in roles)
{
Console.WriteLine(role.Attribute("name").Value);
Console.WriteLine("-----------------------------");
var configurationSettings = role.Element(XName.Get("ConfigurationSettings", ns));
foreach (var element in configurationSettings.Elements(XName.Get("Setting", ns)))
{
var settingName = element.Attribute("name").Value;
var settingValue = element.Attribute("value").Value;
Console.WriteLine(string.Format("{0} = {1}", settingName, settingValue));
}
Console.WriteLine("==========================================");
}
}
Console.ReadLine();
}
}
}
