The following project demonstrates how to create and use JWT (Json Web Token) in ASP.NET Core Web API.

The step by step video can be found here :
https://www.youtube.com/watch?v=MltKzQpaltk

The API manages a sneaker store, it exposes endpoints for CRUD operations over a Sneaker table.

The endpoints are secure with a JWT.

I used SQLExpress in this tutorial.

git clone https://github.com/techwithpat/SneakerAPI

In appsettings.Development.json (under appsettings.json) :

Set the connectionstring to the database

 "ConnectionStrings": {
    "SqlConnection": "The Connection string to your database"
  }

Check Jwt setttings

"JwtSettings": {
    "validIssuer": " String that represents a valid issuer [your name for instance]",
    "validAudience": "http://localhost:35464 or the Url of your API [check in Properties/launchSettings.json]",
    "secret": "yoursecret"
  }

This step should download and install the dependencies.

This step will create all the tables and seed them with some data.

If you use VS, in the package manager console : Update-Database
If you use NET Core CLI : dotnet ef database update

Press F5 to launch the API.
First, with your username / password, you should request an authentication token to the endpoint : /api/auth/login.

Then, include the token in your headers for GET and POST operations : Authorization: Bearer eyJhbGc...........
