Create JSON Web Tokens (JWT) – Using DotNet MVC Core 7.0 – Part 01
Step_01: First of all create a project with some name & in the project create folder named Models.
Right click project file -> Add-> New Folder-> Folder_Name -> click Enter. Now you can see Models folder in project file.
Step_02: In Models folder we will create two class named User & UserDto.
Dto means Data Transfter Object. This class will be used for create user Registration & Login.
Right click Models folder -> Add-> New Class -> select Empty Class -> Type User class name. Now write some code same as below –
namespace Authentication_AuthorizationAPI.Models
{
public class User
{
public string UserName { get; set; } = string.Empty;
public string PasswordHash { get; set; } = string.Empty;
}
}
Here i assign in User class two properties named UserName & PasswordHash which is initiall declared empty string.
Which way we created User class , the same way we will create UserDto class. And Write this code same as below –
using System;
namespace Authentication_AuthorizationAPI.Models
{
public class UserDto
{
public required string UserName { get; set; }
public required string Password { get; set; }
}
}
Above this UserDto class we assigned two properties required. Here user must be fill this properties otherwise user won’t be able to execution.
Step_03: Create Controller class named AuthController.
Right Click Controller folder -> Add -> New Scaffolding -> Api Controller – Empty -> Next -> Write Controller Name -> Press Enter. You will see same as below –
Step_04: Add Crypt.Net-Next NuGet Package Manager.
Right click Dependencies -> NuGet Package -> search NuGet.Net-Next & install it.
Step_05: Create Register method in AuthController. And write this code same as –
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Authentication_AuthorizationAPI.Models;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
namespace Authentication_AuthorizationAPI.Controllers
{
[Route("api/[controller]")]
[ApiController]
public class AuthController : ControllerBase
{
public static User user = new User();
[HttpPost("register")]
public ActionResult<User> Register(UserDto request)
{
string passwordHash = BCrypt.Net.BCrypt.HashPassword(request.Password);
user.UserName = request.UserName;
user.PasswordHash = passwordHash;
return Ok(user);
}
}
}
Here in Register method is a Post method where i passed UserName & Password which type is UserDto. Here i assign request data in user object. After processing this data return User type of data. If we run this project & pass UserDto types of data then it will return below type of data –
Step_06: Create Login method in AuthController. And write this code same as –
[HttpPost("login")]
public ActionResult<User> Login(UserDto request)
{
if (user.UserName != request.UserName)
{
return BadRequest("User not found");
}
if (!BCrypt.Net.BCrypt.Verify(request.Password, user.PasswordHash))
{
return BadRequest("Wrong password");
}
return Ok(user);
}
Here in Login method is a Post method where i passed UserName & Password which type is UserDto. After processing this data return User type of data. here i tried to match user request data with login data. If it matched with login data then we sent user object otherwise sent wrong message.
Step_07: And Finally Create CreateToken method in AuthController. And write this code same as –
Before writing code, first of all we need to install some Nuget package-
- Microsoft.AspNetCore.Authentication.JwtBearer
- System.IdentifyModel.Token.Jwt
After install this Nuget package we will set Token value in appsettings.json file same as below –
Now implement CreateToken method same as below –
private string CreateToken(User user)
{
List<Claim> claims = new List<Claim>
{
new Claim(ClaimTypes.Name, user.UserName)
};
var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_configuration.GetSection("AppSettings:Token").Value!));
var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256Signature);
var token = new JwtSecurityToken(
claims: claims,
expires: DateTime.Now.AddDays(1),
signingCredentials: creds
);
var jwt = new JwtSecurityTokenHandler().WriteToken(token);
return jwt;
}
If we summarize the final code. Then it will be same as below-
using System;
using System.Collections.Generic;
using System.Linq;
using System.Security.Claims;
using System.Text;
using System.Threading.Tasks;
using Authentication_AuthorizationAPI.Models;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Microsoft.IdentityModel.Tokens;
using System.IdentityModel.Tokens.Jwt;
namespace Authentication_AuthorizationAPI.Controllers
{
[Route("api/[controller]")]
[ApiController]
public class AuthController : ControllerBase
{
public static User user = new User();
private readonly IConfiguration _configuration;
public AuthController(IConfiguration configuration)
{
_configuration = configuration;
}
//Register method
[HttpPost("register")]
public ActionResult<User> Register(UserDto request)
{
string passwordHash = BCrypt.Net.BCrypt.HashPassword(request.Password);
user.UserName = request.UserName;
user.PasswordHash = passwordHash;
return Ok(user);
}
//Login method
[HttpPost("login")]
public ActionResult<User> Login(UserDto request)
{
if (user.UserName != request.UserName)
{
return BadRequest("User not found");
}
if (!BCrypt.Net.BCrypt.Verify(request.Password, user.PasswordHash))
{
return BadRequest("Wrong password");
}
string token = CreateToken(user);
return Ok(token);
}
private string CreateToken(User user)
{
List<Claim> claims = new List<Claim>
{
new Claim(ClaimTypes.Name, user.UserName)
};
var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_configuration.GetSection("AppSettings:Token").Value!));
var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256Signature);
var token = new JwtSecurityToken(
claims: claims,
expires: DateTime.Now.AddDays(1),
signingCredentials: creds
);
var jwt = new JwtSecurityTokenHandler().WriteToken(token);
return jwt;
}
}
}
If we run this project then continue Register and Login. We will get JWT (Json Web Token).
