JohannesSteu.JwtAuth

This package is a simple demo how to implement a jwt authentication in Neos Flow. For more details about the JSON Web token itself check https://jwt.io/introduction/.

This mechanism is a great choice to sign for api requests in flow.

This package contains

JwtToken

This class represents a JWT token. This token contains the JWT string wich is sent in your request. The JWT string must be provided in a X-JWT Header. The payload itself must contain a property accountIdentifier.

JwtTokenProvider

The JwtTokenProvider validates a JwtToken. It will first check if the token contains a jwt string at all and then try to decode it with a configured shared secret. If the payload can be decoded it will create a transient account with the data from the payload and set this account as authenticated.

Access data from the payload in flow

This demo implementation will set the full payload into the authenticated token. To access the data in your flow application:

$authenticationToken = $this->securityContext->getAuthenticationTokensOfType(JwtToken::class)[0];
$jwtPayload = $authenticationToken->getPayload();

Example Request

This is a valid request and will be authenticated with the role JohannesSteu.JwtAuth:User in flow:

curl -H "X-JWT=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJhY2NvdW50SWRlbnRpZmllciI6InNvbWUtYWNjb3VudCIsIm5hbWUiOiJKb2huIERvZSJ9.8slTfTqCRozgcby-As6KxeCb5Zq9zX3TmVUcJAgW328" http://your-app.com
