Re: [jersey-dev] debugging ClientRequestFilter with token 
Hi,
Using the client filter looks ok, but you can set the header to the request directly: 

ClientBuilder.newClient().target().request().header(HttpHeaders.AUTHORIZATION, ...)

Debugging the headers is harder. It would be good to see what it comes to the server side, so you can use a @PreMatching filter and put the breakpoint there.
If the server side is not JAX-RS endpoint, you can use WireShark (pcap) to sniff the HTTP transport.
If you feel like debugging Jersey code, the good point is always ServerRuntime#process: https://github.com/eclipse-ee4j/jersey/blob/95c08d35331478ce47c4ae339c7f8542bf69fa22/core-server/src/main/java/org/glassfish/jersey/server/ServerRuntime.java#L200

Try to compare what comes from CURL and what from the Jersey client to the server side.

Hello,


I’m trying to resolve an issue with using a token. Via curl I make a
request like

curl -H 'Authorization: Bearer d2a09f52-fd70-40be-a3d4-2d41cb549d5d'
https://urldefense.com/v3/__https://service-endpoint/api/v1/namespaces/default/deployments__;!!GqivPVa7Brio!P3AaszBZQyjVXPwEj_K3UXwNElyb7EoDqyjUBcaJItsDxS84zXaysPe__Sl5dzGY$

And the response is OK. Then I try to do the same using a
ClientRequestFilter and client. I receive an error code. I tried to
look in the debugger to see what the request header looks like. I
haven’t been able to find it, but maybe I should set the breakpoint
elsewhere.

Then I’m looking for advice regarding what I might be doing wrong, or
where I might find the request header via debugger.


class BearerTokenFilter implements ClientRequestFilter {
   private final String bearerToken;
   public BearerTokenFilter(String bearerToken){
    this.bearerToken = bearerToken;
}
  public static final String FILTER_HEADER_KEY = "Authorization";

   @Override
   public void filter(ClientRequestContext requestContext) throws IOException {
     String bearerTokenString = "Bearer " + bearerToken;
     requestContext.getHeaders().add(FILTER_HEADER_KEY,bearerTokenString);
   }

builder.register(new
BearerTokenFilter(this.bearerToken)).build().property(HttpUrlConnectorProvider.SET_METHOD_WORKAROUND,
true)


Best Regards,
