How to add customer header to Request?

Question

I'm caught in a situation where I need to manually add a header(Authorization) to the request.

The catch is that I only need to add that header to requests coming to a specific API(Controller). Not to all.

I'm using Java 1.8 with Spring Boot.

Is there anyway to achieve this?

Answer 1

This might work for you..

public class MyCustomFilter extends OncePerRequestFilter {
@Override
protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException {
    if(httpServletRequest.getRequestURI().equals("Your custom URI")){
        httpServletResponse.setHeader("Authorization","Your value");
    }
    filterChain.doFilter(httpServletRequest,httpServletResponse);
}
}

For every request, checks the URI and if matches,adds the Authorization header.Also, you will probably need to add @Component annotation.

I guess that this is the answer that you are looking for:

@RequestMapping(value = "/users", method = RequestMethod.GET)
public List<AppUser> getUsers(OAuth2Authentication auth, @RequestHeader (name="Authorization") String token)
