Package com.networknt.aws.lambda.handler.middleware.token

Class TokenMiddleware

  • All Implemented Interfaces:
    LambdaHandler, MiddlewareHandler
    public class TokenMiddleware
extends Object
implements MiddlewareHandler
    This middleware is used to get the jwt token for the client credential grant type and put it into the Authorization header when the backend lambda function is invoking another service. The token is cached in the cache manager and it only retrieves a new one before the current one is expired. This is to support the east west security between the services in the light lambda native platform. The middleware will check if service_id header is in the request. Normally, this id should map to an ALB or API Gateway endpoint that is used to call another Lambda function or a service running in a container. When service_url is in the header, it is going to be used to invoke the downstream API, otherwise, the downstream URL will be discovered from the config.
