dot-net-8-jwt-authentication-api

Welcome to the dot-net-8-jwt-authentication-api project!

This open-source sample project demonstrates a basic implementation of JSON Web Token (JWT) authentication using .NET 8. The project provides a simple example of how to secure an API by generating and verifying JWT tokens for authentication.

Nuget packages references

Install-Package Microsoft.AspNetCore.Authentication.JwtBearer
Install-Package System.IdentityModel.Tokens.Jwt
Install-Package Swashbuckle.AspNetCore

Controllers

The project contains a single controller, UserController, which handles user authentication and retrieval.

Authentication

The Authenticate method is responsible for authenticating a user using the provided credentials. It uses the IUserService interface to authenticate the user and returns an OkResult with the user's details if the authentication is successful. For example send post request to /api/User/authenticate

{
    "username": "admin",
    "password": "admin"
}

Authorization

The CustomAuthorize attribute is used to ensure that the user is authenticated before accessing the GetAll and GetUserById methods.

  1. Clone the project from GitHub: git clone https://github.com/arshambh/dot-net-8-jwt-authentication-api.git
