Are there any IdentityServer4 services (not endpoints) for token handling? - c#

I have IdentityServer4 and a web API in the same project, and I would like to use IdentityServer token handling in my own controllers, e.g. I want to issue tokens, refreshtokens, revoke tokens in my own controllers without calling other built in IdentityServer endpoints.
Are there services for stuff like this I'm missing?
Thanks
I need something like someIdentityServerService below
[AllowAnonymous]
[HttpPost("login")]
public async Task<IActionResult> Login([FromBody] UserLoginRequestDto model)
{
var user = await _userManager.FindByEmailAsync(model.Email);
if (user == null || !await _userManager.CheckPasswordAsync(user, model.Password))
{
return BadRequest("Wrong email or password!");
}
// do some other stuff
var token = await someIdentityServerService.GetAccessTokenAsync(user);
return Ok(token);
}

I do not think, it's a good idea to come inside the certified IdP and call the internals in your own order, not the order defined by the protocol.
Nevertheless you can do that by looking into the implementation and invoking or overriding. Identity Server is highly flexible, using standard DI you can override almost everything.
for instance
var identityPricipal = await _principalFactory.CreateAsync(user);
var identityUser = new IdentityServerUser(user.Id.ToString())
{
AdditionalClaims = identityPricipal.Claims.ToArray(),
DisplayName = user.UserName,
AuthenticationTime = DateTime.UtcNow,
IdentityProvider = IdentityServerConstants.LocalIdentityProvider
};
var request = new TokenCreationRequest();
request.Subject = identityUser.CreatePrincipal();
request.IncludeAllIdentityClaims = true;
request.ValidatedRequest = new ValidatedRequest();
request.ValidatedRequest.Subject = request.Subject;
request.ValidatedRequest.SetClient(Config.Clients().First());
request.Resources = new Resources(Config.IdentityResources(), new List<ApiResource>());
request.ValidatedRequest.Options = _options;
request.ValidatedRequest.ClientClaims = identityUser.AdditionalClaims;
var token = await _tokenService.CreateAccessTokenAsync(request);
token.Issuer = "...";
return await _tokenService.CreateSecurityTokenAsync(token);
More convenient way of creating tokens is to employ IdentityServerTools. However that's aim is to help calling external APIs from within IdSrv, not issuing any JWTs by external requests.
If you need to request JWTs from outside (and follow the protocol), you have to use predefined endpoints and signatures.

is there a way to associate a spotify access token to a ASP.NET identity user?

I'm working on a multilanguage project for accademic purpose. I've written a simple Python Client that make requests to an API server written in ASP.NET. The server retrives spotify info about users. The server interacts with a DB filled by a Golang server that only makes scraping on API's exposed from Spotify. I'm aware that it's a misuse and there are better solutions
Clearly, Golang server, in order to make requests to Spotify API's, needs to know the access token returned from spotify Authorization Code Flow. Overlooking about spotify token expire time, the idea is: after user authentication through Identity module of ASP.NET server (using JWT token), associate the access token obtained calling https://accounts.spotify.com/api/token to user's informations. So, i expose an API in ASP.NET server like this
[AllowAnonymous]
[HttpPost("token")]
public async Task<ContentResult> getTokenAsync(string? code = null)
{
//to retrive information about who is the user that making call -> need later for associate spotifytoken
string accessToken = Request.Headers[HeaderNames.Authorization].ToString().Replace("Bearer ", "");
JwtSecurityTokenHandler t = new JwtSecurityTokenHandler();
var token = t.ReadJwtToken(accessToken);
var user = _userManager.FindByIdAsync(token.Subject).Result;
string s = "https://accounts.spotify.com/api/token";
if (code == null)
{
var qb = new QueryBuilder();
qb.Add("response_type", "code");
qb.Add("client_id", _config["SpotiSetting:clientId"]);
qb.Add("scope", "user-read-private user-read-email user-library-read");
qb.Add("redirect_uri", _config["SpotiSetting:redirectUser"]);
qb.Add("show_dialog", "true");
return new ContentResult
{
ContentType = "text/html",
Content = "https://accounts.spotify.com/authorize/" + qb.ToQueryString().ToString()
//Content = JsonConvert.SerializeObject(user.Result)
};
} else
{
//if i'm here, api is the callback designed for spotify
var qb = new QueryBuilder();
qb.Add("grant_type", "authorization_code");
qb.Add("code", code);
qb.Add("redirect_uri", "https://localhost:44345/spotify/token");
var client = new HttpClient();
var req = new HttpRequestMessage(HttpMethod.Post, s);
req.Content = new FormUrlEncodedContent(qb);
req.Headers.Authorization = new AuthenticationHeaderValue("Basic", "here_my_secret_encoded_CLIENTID:CLIENT_SECRET");
var response = await client.SendAsync(req);
var result = response.Content.ReadAsStringAsync().Result;
AccessToken json = JsonConvert.DeserializeObject<AccessToken>(result);
user.spotifyInformation.authToken = code;
user.spotifyInformation.accessToken = json;
var res = _userManager.UpdateAsync(user);
if (res.IsCompletedSuccessfully)
{
return Content("ok");
}
else
{
Content("Problem");
}
} return Content("");
}
The problem is that the second time that API is invoked, it's spotify that is sending the first authorization token (needed to request access_token), so I lost user information retrived in the first request. Should be better write two distinct API and separate callback from user request?
It's my first question here, so please to have mercy

502.3 when calling AcquireTokenAsync in .NET Core 2.2

I'm encountering a problem. I am using Microsoft Graph to get the current logged in user via OnBehalfOfMsGraphAuthenticationProvider.cs as seen in the following solution.
This has been working flawlessly, but I have been doing some refactoring, and suddenly I get an error when trying to execute my authContext.AcquireTokenAsync() method.
HTTP Error 502.3 - Bad Gateway
The code in question looks like this:
public async Task AuthenticateRequestAsync(HttpRequestMessage request) {
var httpContext = _httpContextAccessor.HttpContext;
//Get the access token used to call this API
string token = await httpContext.GetTokenAsync("access_token");
//We are passing an *assertion* to Azure AD about the current user
//Here we specify that assertion's type, that is a JWT Bearer token
string assertionType = "urn:ietf:params:oauth:grant-type:jwt-bearer";
//User name is needed here only for ADAL, it is not passed to AAD
//ADAL uses it to find a token in the cache if available
var user = httpContext.User;
string userName =
user.FindFirst(ClaimTypes.Upn).Value ?? user.FindFirst(ClaimTypes.Email).Value;
var userAssertion = new UserAssertion(token, assertionType, userName);
//Construct the token cache
var cache = new DistributedTokenCache(user, _distributedCache,
_loggerFactory, _dataProtectionProvider);
var authContext = new AuthenticationContext(_configuration["AzureAd:Instance"] +
_configuration["AzureAd:TenantId"], true, cache);
var clientCredential = new ClientCredential(_configuration["AzureAd:ClientId"],
(string) _configuration["AzureAd:ClientSecret"]);
//Acquire access token
var result = await authContext.AcquireTokenAsync("https://graph.microsoft.com", clientCredential, userAssertion); //This is where it crashes
//Set the authentication header
request.Headers.Authorization = new AuthenticationHeaderValue(result.AccessTokenType, result.AccessToken);
}
I am calling it from my OrdersController:
// POST: api/Orders
[HttpPost]
public async Task<IActionResult> CreateAsync([FromBody] OrderDTO order) {
if (!ModelState.IsValid) {
return BadRequest(ModelState);
}
var graphUser = await this.graphApiService.GetUserProfileAsync();
The refactoring has consisted of dividing my solution into two class library projects and one web project - the latter has the controllers and the React app. GraphAPiClient and the provider are located in the Core library like this:
Screenshot of architecture
So, it turns out that the problem appeared when I upgraded the package Microsoft.IdentityModel.Clients.ActiveDirectory from v3.19.8 to v4.4.1. For some reason, no versions above v3.19.8 work with my code, causing it to crash when I try to make the call to https://graph.microsoft.com, but as soon as I downgraded the problem disappeared.
Try using AcquireToken instead of AcquireTokenAsync
azureAuthenticationContext.AcquireToken

WebTokenRequest and OneDriveClient

I'm trying to implement Onedrive client login by using Connect to identity providers with Web Account Manager
With this method finally I get a token using this code
private static async Task<string> RequestTokenAndSaveAccount(WebAccountProvider Provider, String Scope, String ClientID)
{
try
{
WebTokenRequest webTokenRequest = new WebTokenRequest(Provider, "wl.signin onedrive.appfolder onedrive.readwrite", ClientID);
WebTokenRequestResult webTokenRequestResult = await WebAuthenticationCoreManager.RequestTokenAsync(webTokenRequest);
if (webTokenRequestResult.ResponseStatus == WebTokenRequestStatus.Success)
{
App.settings.onedriveStoredAccountKey = webTokenRequestResult.ResponseData[0].WebAccount.Id;
return webTokenRequestResult.ResponseData[0].Token;
}
return "";
}
catch (Exception ex)
{
Debug.WriteLine(ex.ToString());
return "";
}
}
But I can't use the returned token to create a OnedriveClient because I need a MsaAuthenticationProvider to create the client and it creates its own token ignoring the one coming from the WebTokenRequest, and it doesn't have any method to take the prior token.
There is a way to create a OneDriveClient without going to REST Onedrive API?
Thank you
Edit:
As there are (at this time) two main versions of OneDriveSDK and those are different from each other, there are two ways to achieve this.
OneDrive.SDK 1.x
As #Brad said, an IAuthenticationProvider is needed to create the OneDriveClient.
I got the solution from https://github.com/ginach/Simple-IAuthenticationProvider-sample-for-OneDrive-SDK.
I took the SimpleAuthenticationProvider into my code, and then created the client like this
var client = new OneDriveClient(
new AppConfig(),
/* credentialCache */ null,
new Microsoft.OneDrive.Sdk.HttpProvider(),
new ServiceInfoProvider(new SimpleAuthenticationProvider { CurrentAccountSession = new Microsoft.OneDrive.Sdk.AccountSession { accessToken = AccessToken } }),
ClientType.Consumer);
client.BaseUrl = "https://api.onedrive.com/v1.0";
await client.AuthenticateAsync();
Where the accessToken is taken from the RequestTokenAndSaveAccount method.
OneDrive.SDK 2.x
For this case, the answer given by #dabox is the right solution.
Appending to Brad's answer, you can create a new AuthenticationProivder implements the IAuthenticationProivder interface in the package Microsoft.Graph.Core. And there also is a DelegateAuthenticationProvider in package Microsoft.Graph.Core which provides a Delegate interface for you. An example looks like:
OneDriveClient oneDriveClient = new OneDriveClient(
new DelegateAuthenticationProvider(
async (requestMessage) =>
{
string accessToken = await GetAccessTokenSomeWhereAsync();
// Append the access token to the request.
requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", accessToken);
}));
return oneDriveClient ;
Modified based on the Microsoft Graph's asp .net example: https://github.com/microsoftgraph/aspnet-connect-sample/blob/master/Microsoft%20Graph%20SDK%20ASPNET%20Connect/Microsoft%20Graph%20SDK%20ASPNET%20Connect/Helpers/SDKHelper.cs#L18
OneDriveClient only requires an IAuthenticationProvider, which is a pretty simplistic interface. You can create your own and implement AuthenticateRequestAsync such that it calls your RequestTokenAndSaveAccount and then adds the bearer token to the request.

Search for user in Azure Active directory group using graph api

I would like to have some kind of people picker functionality with auto complete features in my asp.net mvc 5 app to search for a user in a specific Azure AD group. It's a demo "todo app" that allows to assign a todo to a user that is member of a the group.
I tried with both the Graph API directly and the Azure Graph Client library but I don't seem to find a way to achieve what I want. The graph api allows to get the members of a group but adding filter "startswith" fails as when adding the filter the api returns only directory object which don't include for example DisplayName property... the client library doesn't help much either except for the batch functionality which offers a way but with a lot of overhead... I then would have to get a filtered resultset of user regardless of group membership (using User List stuff in the api), all members of the group and then fish out using Linq the correct result set.... would work fine for dev/testing but in production with a couple of hundred users this would be insane...
Any ideas or suggestions would be much appreciated. Thanks!
EDIT
Below my code that is called from client side Javascript to search for user;
AccessGroupId is the Azure AD group used to authorize users. Only
members of this group can access the web app which I handle in custom
OWin Middleware
The method is intented to be used to find a user in that group
Code works fine as below only there is no filtering applied which is the intentaion with the input parameter pre (which comes from a textbox in the ui). I get all the members of the access group.
public async Task<JsonResult> FindUser(string pre)
{
string AccessGroupId = ConfigurationManager.AppSettings["AccessGroupId"];
AuthenticationContext authCtx = new AuthenticationContext(String.Format(CultureInfo.InvariantCulture, "{0}/{1}", SecurityConfiguration.LoginUrl, SecurityConfiguration.Tenant));
ClientCredential credential = new ClientCredential(SecurityConfiguration.ClientId, SecurityConfiguration.AppKey);
AuthenticationResult assertionCredential = await authCtx.AcquireTokenAsync(SecurityConfiguration.GraphUrl, credential);
var accessToken = assertionCredential.AccessToken;
var graphUrl = string.Format("https://graph.windows.net/mytenant.onmicrosoft.com/groups/{0}/members?api-version=2013-11-08, AccessGroupId );
HttpClient client = new HttpClient();
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, graphUrl);
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
HttpResponseMessage response = await client.SendAsync(request);
String responseString = await response.Content.ReadAsStringAsync();
JObject jsonReponse = JObject.Parse(responseString);
var l = from r in jsonReponse["value"].Children()
select new
{
UserObjectId = r["objectId"].ToString(),
UserPrincipalName = r["userPrincipalName"].ToString(),
DisplayName = r["displayName"].ToString()
};
//users = Newtonsoft.Json.JsonConvert.DeserializeObject<List<User>>(responseString);
return Json(l, JsonRequestBehavior.AllowGet);
}
When I add a filter to the same api call instead of returning the members (users, groups and/or contacts), it returns directory objects (that doesn't have displayName) which are not really usefull in the above code, unless I would query the api again (in batch) to retrieve the users displayname but that looks like a lot of overhead to me.
var graphUrl = string.Format("https://graph.windows.net/mytenant.onmicrosoft.com/groups/{0}/members?api-version=2013-11-08&$filter=startswith(displayName,'{1}')", AccessGroupId, pre);
I'd highlight two possible approaches:
Execute requests to Graph API using a custom JS library.
You'd need still need to care for accesstokens and have a look at ADAL.js
A sample app (not finalized as of this writing) available at:
AzureADSamples WebApp-GroupClaims-DotNet
Have a look at AadPickerLibrary.js
Try using ActiveDirectoryClient
It would look something like:
public async Task<JsonResult> FindUser(string pre) {
ActiveDirectoryClient client = AADHelper.GetActiveDirectoryClient();
IPagedCollection<IUser> pagedCollection = await client.Users.Where(u => u.UserPrincipalName.StartsWith(pre, StringComparison.CurrentCultureIgnoreCase)).ExecuteAsync();
if (pagedCollection != null)
{
do
{
List<IUser> usersList = pagedCollection.CurrentPage.ToList();
foreach (IUser user in usersList)
{
userList.Add((User)user);
}
pagedCollection = await pagedCollection.GetNextPageAsync();
} while (pagedCollection != null);
}
return Json(userList, JsonRequestBehavior.AllowGet);
}

Token-based Authorization in Existing ASP.NET MVC App

I have inherited an existing application. This application uses ASP.NET MVC 3. It has some APIs. Those APIs look like the following:
[AcceptVerbs(HttpVerbs.Post)]
[Endpoint]
public ActionResult AuthenticatePlayer(string username, string password)
{
// Ensure that the user entered valid credentials
if (Membership.ValidateUser(username, password) == false)
return Json(new { statusCode = StatusCodes.INVALID_CREDENTIALS, message = "You entered an invalid username or password. Please try again." });
// Get the profile of the person that just logged in.
ProfileCommon userProfile = (ProfileCommon)(ProfileCommon.Create(username));
if (userProfile != null)
{
string name = username;
if (String.IsNullOrEmpty(userProfile.FirstName) == false)
name = userProfile.FirstName;
return Json(new {
statusCode = StatusCodes.SUCCESS,
payload = name,
username = username.ToLower(),
});
}
}
[AcceptVerbs(HttpVerbs.Get)]
[Endpoint]
public ActionResult SomeUserAction(string q)
{
// TODO: Ensure the user is authorized to perform this action via a token
// Do something
return Json(new { original = q, response = DateTime.UtcNow.Millisecond }, JsonRequestBehavior.AllowGet);
}
I'm trying to figure out how to integrate a token-based authorization schema into this process. From my understanding, a token-based system would return a short-lived token and a refresh token to a user if they successfully login. Then, each method can check to see if a user is authorized to perform the action by looking at the token. I'm trying to learn if this is built-in to ASP.NET MVC or if there is a library I can use. I need to figure out the shortest way to get this done.
Thank you so much!
I've built a WebAPI Token Authentication library a year ago, providing Token based authentication:
WebAPI Token Auth Bootstrap is out of the box Token based User Auth for WebAPI applications, Provides ready to use 'TokenAuthorize'
Attribute and 'TokenAuthApiController' Controller.
Among its features - Token Based User Authentication User Property inside the
TokenAuthApiController (Id, Username, Role, LastAccess).
Token Based User Authorization TokenAuthorizeAttribute with Access
Level - Public, User, Admin or Anonymous.
Built-in Functionality Login(), Logoff(), Error(), Unauthorized()
Responses with various overloads.
You can read more about here and in its own wiki in GitHub.
Nowadays I am working on a Node.js application and I am using Json Web Tokens (JWT) using Node.js library and it is very easy and straightforward.. its Node.js after all ;)
I saw there is a .NET implementation of JWT explained on this article which I recommend you to look at.
You can use Owin ... i.e. Microsoft.owin.security
I haven't tried this implementation but this is just to give you an idea:
var identity = new ClaimsIdentity(Startup.OAuthBearerOptions.AuthenticationType);
var currentUtc = new SystemClock().UtcNow;
ticket.Properties.IssuedUtc = currentUtc;
ticket.Properties.ExpiresUtc = currentUtc.Add(TimeSpan.FromMinutes(30));
DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
return Json(new {
statusCode = StatusCodes.SUCCESS,
payload = name,
username = username.ToLower(),
accessToken = Startup.OAuthBearerOptions.AccessTokenFormat.Protect(ticket)
});
