I am trying to call generated feign client from reactive spring flux like this:
.doOnNext(user1 -> {
ResponseEntity<Void> response = recorderClient.createUserProfile(new UserProfileDto().principal(user1.getLogin()));
if (!response.getStatusCode().equals(HttpStatus.OK)) {
log.error("recorder backend could not create user profile for user: {} ", user1.getLogin());
throw new RuntimeException("recorder backend could not create user profile for login name" + user1.getLogin());
}
})
Call is executed, but when I try to retrieve jwt token from reactive security context ( in a requets interceptor ) like this:
public static Mono<String> getCurrentUserJWT() {
return ReactiveSecurityContextHolder
.getContext()
.map(SecurityContext::getAuthentication)
.filter(authentication -> authentication.getCredentials() instanceof String)
.map(authentication -> (String) authentication.getCredentials());
}
....
SecurityUtils.getCurrentUserJWT().blockOptional().ifPresent(s -> template.header(AUTHORIZATION_HEADER, String.format("%s %s", BEARER, s)));
context is empty. As I am pretty new to reactive spring I am surely mussing something stupid and important.
Not sure how is your interceptor configured, but in my case, i just simply implement ReactiveHttpRequestInterceptor and override apply() function
import feign.RequestInterceptor;
import feign.RequestTemplate;
import org.springframework.stereotype.Component;
import reactivefeign.client.ReactiveHttpRequest;
import reactivefeign.client.ReactiveHttpRequestInterceptor;
import reactor.core.publisher.Mono;
import java.util.Collections;
@Component
public class UserFeignClientInterceptor implements ReactiveHttpRequestInterceptor {
private static final String AUTHORIZATION_HEADER = "Authorization";
private static final String BEARER = "Bearer";
@Override
public Mono<ReactiveHttpRequest> apply(ReactiveHttpRequest reactiveHttpRequest) {
return SecurityUtils.getCurrentUserJWT()
.flatMap(s -> {
reactiveHttpRequest.headers().put(AUTHORIZATION_HEADER, Collections.singletonList(String.format("%s %s", BEARER, s)));
return Mono.just(reactiveHttpRequest);
});
}
}
