i'm developing an application with spring boot, spring cloud, and Zuul as gateway.

With Spring Security i created an authorization service which will generate a JWT token when the user login.

The Zuul Gateway can decode this token and let the request go inside my application to the routed services.

The question now is, how can i get the logged user (or the token itself) in one of the microservices? Is there a way to tell the Zuul gateway to attach the token to every request he passes to a routed path?

All the microservices do not have Spring Security as a dependency, because the idea is to check the token only at the gateway level, not everywhere, but i can't find a proper way to do so...

Let's say I have a User Service routed in the gateway. After the login the user wants to check his profile.

He will make a request to `{{gateway_url}}/getUser` with the token.

The gateway configuration is

```
zuul:
  ignored-services: '*'
  sensitive-headers: Cookie,Set-Cookie
  routes:
    user-service:
      path: /user/**
      service-id: USER-SERVICE

```

The gateway will route this request to the USER-SERVICE application, to the `getProfile` controller method how can i know which is the logged user? Who made the request?
