In my project HttpContext is a member of Controller and I can use it in AccountController : Controller. But I can't access an information about current user in ApiController in contraction like
public class AccountController : ApiController
{
public UserManager<ApplicationUser> UserManager { get; private set; }
private IAuthenticationManager AuthenticationManager
{
get
{
return HttpContext.Current.GetOwinContext().Authentication;
}
}
}
So how to write custom ApiController right?
In the method below user variable shows me null on breakpoint. How can I retrive current user if I know that hi is logined?
public IHttpActionResult GetUser(int id)
{
var manager = HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>();
var userid = User.Identity.GetUserId();
var user = manager.FindById(userid);
var data = new Person {Name = user.UserName, Age = 99};
return Ok(data);
}
From within any controller method you can do this.GetRequestContext().User to get the currently authenticated user. The static HttpContext.Current is not supported by WebApi.
manager.FindById(userid) retrieves a user from the database as opposed to the current . To get the current user, simply access the User property within your ApiController:
public class MyApiController : ApiController
{
IPrincipal GetCurrentUser(){
return User;
}
}
This may help you:
protected string UserId { get { return User.Identity.GetUserId(); } }

I'm trying to make a simple request using mediator and .net core. I'm getting an error that I am not understanding. All I'm trying to do is a simple call to get back a guid.
BaseController:
[Route("api/[controller]/[action]")]
[ApiController]
public class BaseController : Controller
{
private IMediator _mediator;
protected IMediator Mediator => _mediator ?? (_mediator = HttpContext.RequestServices.GetService<IMediator>());
}
Controller:
// GET: api/Customer/username/password
[HttpGet("{username}/{password}", Name = "Get")]
public async Task<ActionResult<CustomerViewModel>> Login(string username, string password)
{
return Ok(await Mediator.Send(new LoginCustomerQuery { Username = username,Password = password }));
}
Query:
public class LoginCustomerQuery : IRequest<CustomerViewModel>
{
public string Username { get; set; }
public string Password { get; set; }
}
View Model:
public class CustomerViewModel
{
public Guid ExternalId { get; set; }
}
Handler:
public async Task<CustomerViewModel> Handle(LoginCustomerQuery request, CancellationToken cancellationToken)
{
var entity = await _context.Customers
.Where(e =>
e.Username == request.Username
&& e.Password == Encypt.EncryptString(request.Password))
.FirstOrDefaultAsync(cancellationToken);
if (entity.Equals(null))
{
throw new NotFoundException(nameof(entity), request.Username);
}
return new CustomerViewModel
{
ExternalId = entity.ExternalId
};
}
This is the exception I am getting:
Please let me know what else you need to determine what could be the issue. Also, be kind I have been away from c# for a while.
Thanks for the info it was the missing DI. I added this
// Add MediatR
services.AddTransient(typeof(IPipelineBehavior<,>), typeof(RequestPreProcessorBehavior<,>));
services.AddMediatR(typeof(LoginCustomerQueryHandler).GetTypeInfo().Assembly);
and we are good to go.
I want to use custom register identity method that is called in a controller to Register users automatically with a corresponding role. Here the code that I found so far:
public class RegisterUsers
{
private readonly UserManager<ApplicationUser> _userManager;
public RegisterUsers(UserManager<ApplicationUser> userManager)
{
_userManager = userManager;
}
public async Task SystmRegisterUsers(string uname, string sysid, string Email)
{
var newuser = new ApplicationUser
{
UserName = uname,
Email = Email,
SystemuserID = sysid
};
string UserPassword = PasswordGenerator.Generate(6, 3, true, true, true, true);
//var _user = await UserManager.FindByEmailAsync(Configuration.GetSection("UserSettings")["UserEmail"]);
var createParentUser = await _userManager.CreateAsync(newuser, UserPassword);
if (createParentUser.Succeeded)
{
//here we tie the new user to the "Admin" role
await _userManager.AddToRoleAsync(newuser, "Parent");
}
}
}
And I want to call the method SystmRegisterUsers like this in a controller
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Create([Bind("fullname,id,email,...")]MyModel parent)
{
if (ModelState.IsValid)
{
//create new records
_context.Add(parent);
await _context.SaveChangesAsync();
// and i want to call the method here to create identity users using the data entered:
var instance = new RegisterUsers();
await instance.SystmRegisterUsers(parent.FullName, parent.Parentid, parent.Parentid);
}
return View(parent);
}
And it is saying I’m missing an argument that is corresponds to userManager . I don’t even know if it is the right way to do what I want to do, I think I’m missing some basic thing please help!
For RegisterUsers, it needs UserManager<ApplicationUser> userManager, for resolving the RegisterUsers from Dependency Injection, you could follow steps below:
Register RegisterUsers in Startup.cs
public void ConfigureServices(IServiceCollection services)
{
//your rest code
services.AddScoped<RegisterUsers>();
}
Initialize RegisterUsers by Dependency Injection
public class HomeController : Controller
{
private readonly RegisterUsers _registerUsers;
public HomeController(RegisterUsers registerUsers)
{
_registerUsers = registerUsers;
}
public async Task<IActionResult> Index()
{
await _registerUsers.SystmRegisterUsers("a1", "b1", "c1");
return View();
}
I wanted to save notification in TempData and shown to user. I create extension methods for this and implement a class which Extends from ActionResult. I need to access TempData in override ExecuteResult method with ActionContext.
Extension Method:
public static IActionResult WithSuccess(this ActionResult result, string message)
{
return new AlertDecoratorResult(result, "alert-success", message);
}
Extends ActionResult class.
public class AlertDecoratorResult : ActionResult
{
public ActionResult InnerResult { get; set; }
public string AlertClass { get; set; }
public string Message { get; set; }
public AlertDecoratorResult(ActionResult innerResult, string alertClass, string message)
{
InnerResult = innerResult;
AlertClass = alertClass;
Message = message;
}
public override void ExecuteResult(ActionContext context)
{
ITempDataDictionary tempData = context.HttpContext.RequestServices.GetService(typeof(ITempDataDictionary)) as ITempDataDictionary;
var alerts = tempData.GetAlert();
alerts.Add(new Alert(AlertClass, Message));
InnerResult.ExecuteResult(context);
}
}
Call extension method from controller
return RedirectToAction("Index").WithSuccess("Category Created!");
I get 'TempData ' null , How can I access 'TempData' in 'ExecuteResult' method.
I was literally trying to do the exact same thing today (have we seen the same Pluralsight course? ;-) ) and your question led me to find how to access the TempData (thanks!).
When debugging I found that my override on ExecuteResult was never called, which led me to try the new async version instead. And that worked!
What you need to do is override ExecuteResultAsync instead:
public override async Task ExecuteResultAsync(ActionContext context)
{
ITempDataDictionaryFactory factory = context.HttpContext.RequestServices.GetService(typeof(ITempDataDictionaryFactory)) as ITempDataDictionaryFactory;
ITempDataDictionary tempData = factory.GetTempData(context.HttpContext);
var alerts = tempData.GetAlert();
alerts.Add(new Alert(AlertClass, Message));
await InnerResult.ExecuteResultAsync(context);
}
However, I have not fully understood why the async method is called as the controller is not async... Need to do some reading on that...
I find out the way to get the TempData. It need to get from ITempDataDictionaryFactory
var factory = context.HttpContext.RequestServices.GetService(typeof(ITempDataDictionaryFactory)) as ITempDataDictionaryFactory;
var tempData = factory.GetTempData(context.HttpContext);
I'm currently trying to implement a simple WebAPI 2.0 controller to get and retrieve users from a central table.
Looking at implementing :
GetUserByName(string userName)
GetUserByID(int userId)
GetUserByEmail(string email)
Using Routing I have been able to get the api to work with GetById and GetByName. I have also added a route prefix to the controller level
The code looks like this so far, There isn't very much being done in the API controller at the moment I just wish to test that the correct methods are being hit.
[RoutePrefix("api/user")]
public class UserController : ApiController
{
[Route("")]
[HttpGet]
public IEnumerable<User> Get()
{
return new List<User>();
}
// GET: api/Users/5
[Route("{id:int}")]
public User Get(int id)
{
return new User();
}
[Route("{id}/PasswordHash")]
[HttpGet]
public string PasswordHash(int id)
{
return "test";
}
[Route(Name = "/{userName:alpha}")]
public User GetByName(string userName)
{
return new User();
}
[Route(Name = "/GetByEmail/{email}")]
[HttpGet]
public User GetByEmail(string email)
{
return new User()
}
// POST api/<controller>
[HttpPost]
[Route("")]
public string Post([FromBody]User value)
{
return "test";
}
}
Once I add in the get by email it doesn't seem to work, I've tried giving the method it's own custom routing but unfortunately it doesn't seem to work. Any suggestions would be great.
You have set the name of the routes not the routes themselves, and since both methods have the same signature with one string variable you get the problem, so change your code to be :
[Route("/{userName:alpha}")]
public User GetByName(string userName)
{
return new User();
}
[Route("/GetByEmail/{email}")]
[HttpGet]
public User GetByEmail(string email)
{
return new User()
}
hope this helps.
I've created WebApi controller based on following tutorial: sebastienros website
My modules name is Company.Accounts.
public class AccountController : ApiController
{
[HttpPost]
public string LogIn([FromBody] UserModel user)
{
// this is working
return this.accountService.LogIn(user.UserName, user.Password);
}
[HttpPut]
public string SomePuthMethod([FromBody] UserModel user)
{
// method not allowed
// some code...
}
}
Implementation of IHttpRouteProvider looks like:
private IEnumerable<RouteDescriptor> GetAccountRoute()
{
yield return new HttpRouteDescriptor
{
Name = "Account",
Priority = 10,
RouteTemplate = "Api/Account",
Defaults = new
{
area = "Company.Accounts",
controller = "Account"
}
};
}
Unfortunately, everything except GET and POST *is not working*. I'm getting simple
Method not allowed.
What's wrong? My Orchard version is 1.7.1.
You put them in the MethodNames public HttpResponseMessage Post([FromBody]...){}
