I'm using ASP.Net Identity and in my Web Api project in its AccountController I want to send verification email to new users. I have plugged my email service using MVCMailer to the ASP.Net identity.
public class EmailService : IIdentityMessageService
{
private readonly IUserMailer _userMailer;
public EmailService(IUserMailer userMailer)
{
_userMailer = userMailer;
}
public Task SendAsync(IdentityMessage message)
{
_userMailer.DeliverMessage(message.Body);
// Plug in your email service here to send an email.
return Task.FromResult(0);
}
}
#
public class UserMailer : MailerBase, IUserMailer
{
public UserMailer()
{
MasterName = "_Layout";
}
public virtual IMailMessage DeliverMessage(string message)
{
var mailMessage = new MailMessage();
mailMessage.To.Add("hashemp206#yahoo.com");
mailMessage.Subject = "Welcome";
//ViewData = new System.Web.Mvc.ViewDataDictionary(model);
PopulateBody(mailMessage, "Welcome");
mailMessage.Send();
return mailMessage;
}
my custom ASP.Net Identiy is in a seperate project. and as you see above EmailService is dependent on IUserMailer interface. and IUserMailer implementation is in another project MyProject.MVCMailer (this project is an MVC project)
in my dependency resolver in web api I try to resolve this dependency
container.Bind<IUserMailer>().To<UserMailer>().InSingletonScope();
but MVCMailer has a dependency to System.Web.MVC and ninject complain for this reference to initialize USerMailer.
so the problem is here I dont want to add System.Web.MVC to my Web Api project.
how can I use MVCMailer without referencing to System.Web.MVC in my web api project?
I'm a little confused on what you're trying to do but if I'm understanding you correctly you are trying to call your API and then send out an email. Since you are not passing anything from the API into the email (and even if you were) just call your API and return a response object. Once the MVC project recieves the response send the email from the MVC project. Your API should know about objects in your MVC project unless there is a really good reason. Think of them (your MVC and API projects) as two separate entities all together that don't know about each other.

I am trying to migrate OAuth server code written for .Net Framework 4.5 to .Net Core 3.1. The original code pretty much looks like this. It implements the IAuthorizationServerHost interface. It makes sense to me that it has some functions that the server should implement (like CreateAccessToken that generates and returns a token).
But for .Net Core 3.1, DotNetOpenAuth is not available. So I searched around and found apparently the best solution IdentityServer4 along with many other tutorials (Tut1 Tut2 etc.). But all those looked to me as if they have just implemented the Identity Server (basically just login, logout and register). I don't see how is the token been issued.
My controller class in .Net Framework 4.5 looks like this. A successful login is usually followed by oauth/authorize route that provisions the token and redirects back to the third party.
public class OAuthController : Controller
{
// OAuth2AuthorizationServer is an implementation if IAuthorizationServerHost
private readonly AuthorizationServer authorizationServer = new AuthorizationServer(new OAuth2AuthorizationServer());
public ActionResult Token()
{
var result = this.authorizationServer.HandleTokenRequest(this.Request).AsActionResult();
return result;
}
[Authorize, AcceptVerbs(HttpVerbs.Get | HttpVerbs.Post)]
public ActionResult Authorize()
{
var request = this.authorizationServer.ReadAuthorizationRequest(this.Request);
if (request == null)
{
throw new HttpException((int)HttpStatusCode.BadRequest, "Bad request");
}
var response = authorizationServer.PrepareApproveAuthorizationRequest(request, User.Identity.Name);
return authorizationServer.Channel.PrepareResponse(response).AsActionResult();
}
}
I am new to this authentication stuff - have a quite hollow understanding of the concepts. I am struggling to understand the OAuth server related code flow in these tutorials.
So how can I use those packages to create an OAuth server in .Net Core 3.1?
I'm trying to port a asp.net mvc 3.0 to Asp.Net Core 3.0 but now I'm stuck and Cannot find UrlHelper.GenerateUrl in .Net Core 3.0. even the UrlHelper in Microsoft.AspNetCore.Mvc.Routing doesn't have GenerateUrl, seems like it is removed in .Net Core version 3.0. are there any replacements?
You can use the LinkGenerator. From the documentation:
URL generation is based on addresses, which support arbitrary
extensibility:
The Link Generator API (LinkGenerator) can be resolved anywhere using dependency injection (DI) to generate URLs.
Where the Link Generator API isn't available via DI, IUrlHelper offers methods to build URLs.
DI example:
public class MyController : Controller
{
private readonly LinkGenerator _linkGenerator;
public MyController(LinkGenerator linkGenerator)
{
_linkGenerator = linkGenerator;
}
public IActionResult Index()
{
var url = _linkGenerator.GetPathByAction(nameof(Index), "My", new { someParameter });
// ...
}
}
I am developing a website using ASP.NET MVC with an API using ServiceStack.
Very soon I want to add authentication. The website will have at least two types of users 'service providers' and 'service consumers', although a user could have multiple roles.
I am open to using new MVC Identity, but I want whatever I use to work nicely for both the servicestack API and MVC 'pages' that don't necessarily use the API but should show different content based on login. I do not want to require javascript for login/logout.
I would like the solution to use tokens as I have not used session state anywhere else, but I am open to other options providing they would scale horizontally on a cloud provider (users next request may go to a different instance of back-end).
Anyone have example of an ideal solution?
(N.B: I am not interested in an externally hosted service).
ServiceStack's Authentication can also be used by external ASP.NET Web Frameworks, the ServiceStack and MVC Integration docs shows how you can accept Login credentials from a MVC Controller and register them with ServiceStack:
public ActionResult Login(string userName, string password, string redirect=null)
{
if (ModelState.IsValid)
{
try
{
using (var authService = ResolveService<AuthenticateService>())
{
var response = authService.Authenticate(new Authenticate {
provider = CredentialsAuthProvider.Name,
UserName = userName,
Password = password,
RememberMe = true,
});
// add ASP.NET auth cookie
FormsAuthentication.SetAuthCookie(userName, true);
return Redirect(string.IsNullOrEmpty(redirect) ? "/" : redirect);
}
}
catch (Exception ex)
{
ModelState.AddModelError(string.Empty, ex.Message);
}
}
return View("Index", GetViewModel());
}
The http://mvc.servicestack.net Live Demo shows an example of calling this controller using a standard MVC HTML Form.
Your MVC Controllers can then inherit ServiceStackController to access the Authenticated Users Session and different ServiceStack providers, here are the API's relating to Session and Authentication:
public class ServiceStackController : Controller
{
//...
ISession SessionBag { get; set; }
bool IsAuthenticated { get; set; }
IAuthSession GetSession(bool reload = true);
TUserSession SessionAs<TUserSession>();
void ClearSession();
}
Enable OAuth Providers
Should you need to you can also enable ServiceStack's different OAuth providers which can optionally callback either directly to a ServiceStack Service or
Further to mythz answer I also needed to know if a user was authenticated in a view and the normal Request.IsAuthenticated does not work when your doing above. So I created a CustomWebViewPage (to use this you will have to change *pageBaseType="Your.NameSpace.CustomWebViewPage" in the View folder's Web.config).
public abstract class CustomWebViewPage : WebViewPage
{
private IServiceStackProvider _serviceStackProvider;
public virtual IServiceStackProvider ServiceStackProvider
{
get
{
return _serviceStackProvider ?? (_serviceStackProvider =
new ServiceStackProvider(new AspNetRequest(base.Context, GetType().Name)));
}
}
public virtual bool IsAuthenticated
{
get { return ServiceStackProvider.IsAuthenticated; }
}
}
public abstract class CustomWebViewPage<TModel> : WebViewPage<TModel>
{
//EXACTLY the same as above method...
I have a need to use a .net client to connect to a Signalr enabled application.
The client class needs to be a singleton and loaded for use globally.
I want to know what is the best technique for using singletons globally within an MVC application.
I have been looking into using the application start to get the singleton, where I keep it is a mystery to me.
The HUB cant be a singleton by design SignalR creates a instance for each incoming request.
On the client I would use a IoC framework and register the client as a Singleton, this way eachb module that tries to get it will get the same instance.
I have made a little lib that takes care of all this for you, install server like
Install-Package SignalR.EventAggregatorProxy
Read here for the few steps to hook it up, it needs a back plate service bus or event aggregator to be able to pickup your events
https://github.com/AndersMalmgren/SignalR.EventAggregatorProxy/wiki
Once configured install the .NET client in your client project with
Install-Package SignalR.EventAggregatorProxy.Client.DotNet
See here how to set it up
https://github.com/AndersMalmgren/SignalR.EventAggregatorProxy/wiki/.NET-Client
Once configured any class can register itself as a listener like
public class MyViewModel : IHandle<MyEvent>
{
public MyViewModel(IEventAggregator eventAggregator)
{
eventAggregator.Subscribe(this);
}
public void Handle(MyEvent message)
{
//Act on MyEvent
}
}
On the server you can send a message from outside the hub to all connected clients using the GetClients() method like this:
public MyHub : Hub
{
// (Your hub methods)
public static IHubConnectionContext GetClients()
{
return GlobalHost.ConnectionManager.GetHubContext<MyHub>().Clients;
}
}
You can use it like this:
MyHub.GetClients().All.SomeMethod();
I'm having a class and interface like this in my wcf application IService1.cs
[ServiceContract]
public interface IService1
{
[OperationContract]
string insertValues(empInfo objInfo);
}
[DataContract]
public class empInfo
{
string _organizationName = string.Empty;
string _organizationAddr = string.Empty;
int? _totalemp;
}
And in Service1.svc.cs, i have implemented that interface.
public class Service1 : IService1
{
public string insertValues(empInfo objInfo)
{
.....
}
}
then i have created a empty mvc4 client application to consume this wcf service.
i have added the ServiceReference,Now its appear in the service reference folder as ServiceReference1.Then i did this
1. created a controller named Defalut1controller.
2. In this controller i try to add the following line
ServiceReference1.Service1Client proxy = new ServiceReference1.Service1Client();
inside the ActionResult. But unable to get the ServiceReference1 word.
its (ServiceReference1) appearing when i update my service like this
From - string insertValues(empInfo objInfo); - To - string insertValues(string objInfo);
and now i have build this wcf application, and update the service reference in my client mvc4 application. Now the
ServiceReference1.Service1Client proxy = new ServiceReference1.Service1Client();
line is enabled.
I have tried with the .net web application to consume the same, i can able to do without any problem, what i have missed with mvc4, please help. thanks in advance..
I got the answer, thanks to stackoverflow.
This is the solution:
Right click on Service Reference
Select Configure Service Reference
Select Reuse types in specified referenced assemblies
Just select everything except "Newtonsoft.json"
It worked for me as well.
The question itself and the problem you are facing is a bit unclear for me but have you actually tried exposing any public properties on your empInfo data contract? Cause right now you have only 3 private fields which will not be generated in the proxy code on the client side.
