How can i change authentication type as phone number instead of user name on my web api? - authentication

Question

My authentication is working fine on it is own but i need to use phoneNumber of users instead of user names.
There is my Provider class
using Identity.Infrastructure;
using Microsoft.AspNet.Identity.Owin;
using Microsoft.Owin.Security;
using Microsoft.Owin.Security.OAuth;
using System.Security.Claims;
using System.Threading.Tasks;
namespace Identity.Providers
{
public class CustomOAuthProvider : OAuthAuthorizationServerProvider
{
public override Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
{
context.Validated();
return Task.FromResult<object>(null);
}
public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
var allowedOrigin = "*";
context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] { allowedOrigin });
var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();
ApplicationUser user = await userManager.FindAsync(context.UserName, context.Password);
if (user == null)
{
context.SetError("invalid_grant", "The user name or password is incorrect.");
return;
}
if (!user.EmailConfirmed)
{
context.SetError("invalid_grant", "User did not confirm email.");
return;
}
ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(userManager, "JWT");
var ticket = new AuthenticationTicket(oAuthIdentity, null);
context.Validated(ticket);
}
}
}
in this class context is coming with only userName and Password,so it cant reach PhoneNumber even i send it as a parameter.I think problem will solve after if i can change
userManager.FindAsync(context.UserName, context.Password)
like this
userManager.FindAsync(context.PhoneNumber, context.Password)
VS doesn't allow me to interfere OAuthGrantResourceOwnerCredentialsContext
using Identity.Infrastructure;
using Microsoft.AspNet.Identity.EntityFramework;
using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Web.Http.Routing;
namespace Identity.Models
{
public class ModelFactory
{
private UrlHelper _UrlHelper;
private ApplicationUserManager _AppUserManager;
public ModelFactory(HttpRequestMessage request, ApplicationUserManager appUserManager)
{
_UrlHelper = new UrlHelper(request);
_AppUserManager = appUserManager;
}
public UserReturnModel Create(ApplicationUser appUser)
{
return new UserReturnModel
{
Url = _UrlHelper.Link("GetUserById", new { id = appUser.Id }),
Id = appUser.Id,
UserName = appUser.UserName,
FullName = string.Format("{0} {1}", appUser.FirstName, appUser.LastName),
Email = appUser.Email,
EmailConfirmed = true,
Level = appUser.Level,
JoinDate = appUser.JoinDate,
Roles = _AppUserManager.GetRolesAsync(appUser.Id).Result,
Claims = _AppUserManager.GetClaimsAsync(appUser.Id).Result,
PhoneNumber = appUser.PhoneNumber
};
}
public RoleReturnModel Create(IdentityRole appRole)
{
return new RoleReturnModel
{
Url = _UrlHelper.Link("GetRoleById", new { id = appRole.Id }),
Id = appRole.Id,
Name = appRole.Name
};
}
}
public class RoleReturnModel
{
public string Url { get; set; }
public string Id { get; set; }
public string Name { get; set; }
}
public class UserReturnModel
{
public string Url { get; set; }
public string Id { get; set; }
public string UserName { get; set; }
public string FullName { get; set; }
public string PhoneNumber { get; set; }
public string Email { get; set; }
public bool EmailConfirmed { get; set; }
public int Level { get; set; }
public DateTime JoinDate { get; set; }
public IList<string> Roles { get; set; }
public IList<System.Security.Claims.Claim> Claims { get; set; }
}
}
As result I stucked on authenticating with phoneNumber instead of userName and set deviceId as password

Answer 1

public override Task<ApplicationUser> FindAsync(string Phone, string password)
{
//Do your Stuff here
//return base.FindAsync(userName, password);
}
Overrride FIndAsync() in the IndentityConfig.cs
