simple_aspnet_auth

Simple ASP.NET Authorisation boilerplate project. No EF, no database, no IdentityServer4, no session storage, just a basic logging in system for both cookies and JWT with a couple of authorisation policies and a controller with a set of examples.

Getting Started

To get up and running just cd to the root where the .csproj file resides and run the following commands.

cd examples/cookies+api
dotnet run

Examples

The app simulates a basic group based admin system. There are three groups users can be members of: users, superusers and admins. All users are members of the users group but not all are members of superusers and or admins and there are parts of the app that use the Authorize attribute with policy based access to filter access.

There are a series of logins to test out. The home page has a table of the available users and passwords and indicates if a user is a member of superusers and / or admins.

You can then run the series of tests below and see which sections you are able to view dependent upon login. All the tests make calls to the ExampleController class.

Cookies

Browse to http://localhost/auth and if you are logged in under any user you should see the following.

Only authenticated cookie based requests from superusers receive this message.

Browse to http://localhost/superuser and if you are logged in under a user in either superusers or admins you should see the following.

Only authenticated cookie based requests from superusers receive this message.

Browse to http://localhost/admin and if you are logged in under a user in admins you should see the following.

Only authenticated cookie based requests from admins receive this message.

JWT

The first command gets a token which will be needed for subsequent requests. In the example below the user admin with the password password is used but there are other logins to test which will give different results.

curl -X POST http://localhost:5000/api/login -H "Content-Type: application/x-www-form-urlencoded" -d "Name=admin&Password=password"

The above command should result in something similar to the following (obviously the token value will be different).

{  
   "token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJhZG1pbkBkb21haW4iLCJqdGkiOiJkNGM5MDE0Zi0zOGYxLTQ3NTItODU3YS03ZTc0YzU0MjY3ZDciLCJodHRwOi8vc2NoZW1hcy54bWxzb2FwLm9yZy93cy8yMDA1LzA1L2lkZW50aXR5L2NsYWltcy9uYW1lIjoiYWRtaW4iLCJhZG1pbnMiOiIxIiwic3VwZXJ1c2VycyI6IjIiLCJ1c2VycyI6IjMiLCJleHAiOjE1MDQzODk0NTEsImlzcyI6Imh0dHA6Ly9sb2NhbGhvc3Q6NTAwMC9hcGkvIiwiYXVkIjoiaHR0cDovL2xvY2FsaG9zdDo1MDAwL2FwaS8ifQ.gFnf39Vj16vEmcI1HdwPajH6sRHusxtjZ2eh0Xc1cJs"
}

The token value is then used with subsequent requests. For the examples below replace TOKEN_VALUE with whatever value is obtained from the step above.

curl http://localhost:5000/api/auth -H "Authorization: Bearer TOKEN_VALUE"

No matter what user your token is for you should see the following.

Only authenticated token based requests receive this message.

The following test will work for users in either superusers or admins.

curl http://localhost:5000/api/superuser -H "Authorization: Bearer TOKEN_VALUE"

The above command should produce the following.

Only authenticated token based requests from superusers receive this message.

The following test will work for users in admins.

curl http://localhost:5000/api/admin -H "Authorization: Bearer TOKEN_VALUE"

The above command should produce the following.

Only authenticated token based requests from admins receive this message.

The following example illustrates manipulating the JWT, the code is in the TokenInfo method of the ExampleController class.

curl http://localhost:5000/api/tokeninfo -H "Authorization: Bearer TOKEN_VALUE"

Any authenticated user should be presented with something similar to the following.

      "audiences":[  
         "http://localhost:5000/api/"

Cookies and JWT

The address http://localhost/auth is available for both cookie and JWT based logins and the user should see the following message after execution.

Only authenticated requests receive this message.
