An API that manages Currencies and Currency rates written in .Net Core

It is a Demo CRUD application.

1. Download or clone the project.

2. Database setup: You can leave the settings as is and use the in memory db or you can change the appsettings.json not to use inMemoryDB and use your Sql Server as below:

"AppSettings": {
    "UseInMemoryDatabase":"False",
...
  },
...
  "ConnectionStrings": {
    "DefaultConnection": "Server=localhost;Database=YOUR_DB_NAME;User Id=YOUR_DB_USER;Password=YOUR_PASSWORD;"
  }

If you chose to use Sql Server, in a terminal, navigate in the project's folder and run the command:

dotnet ef database update

3. In a terminal, navigate in the currency-api folder and run the command

dotnet run

4. Navigate to the swagger endpoint to browse all the available endpoints and actions.

5. Go to the publicly available (unprotected) Auth login and Execute a POST call with the admin account (has all the roles and has unlimited access):

{
  "userName": "admin",
  "password": "admin123",
}

Or the simple user account (Can access -read- only the currency rates, login or reset password):

{
  "userName": "user",
  "password": "user123",
}

You will receive a UserDTO object as an answer from the API. The Token property will be populated with the Api JWT access token.

6. On the Swagger UI top-right click on the "Authorize" button and enter:

Bearer _the_token_you_received_from _the_login_call_

And click Authorize.

Now you can browse in the API from the swagger UI.
