EzyHTTP Request Inteceptor
Every request to EzyHTTP will be pass interceptors. You can define one or multipe interceptors for logging, authentication or any purposes.
1. Interceptor for logging
You can define an interceptor with a logger for logging purpose like this:
@Interceptor
public class LogRequestInterceptor
extends EzyLoggable
implements RequestInterceptor {
@Override
public boolean preHandle(RequestArguments arguments, Method handler) throws Exception {
// you can remove this method if you don't need do anything
return true;
}
@Override
public void postHandle(RequestArguments arguments, Method handler) {
logger.info(
"request: {}, response: {}",
arguments.getRequest().getRequestURI(),
arguments.getResponse().getStatus()
);
}
}
2. Interceptor for authentication
EzyHTTP provides @Authenticated annotation. You can use this annotation to any controllers or controller's methods, then EzyHTTP will know which APIs are mapping to the controllers or methods is authenticated. So you can use RequestURIManager.isAuthenticatedURI and interceptor to authencated client's requests like this:
@Interceptor
@AllArgsConstructor
public class AuthenticationInterceptor extends EzyLoggable implements RequestInterceptor {
private final RequestURIManager requestUriManager;
private final IAuthenticationService authenticationService;
@Override
public boolean preHandle(RequestArguments arguments, Method handler) throws Exception {
logger.info("request uri: {}", arguments.getRequest().getRequestURI());
final HttpMethod method = arguments.getMethod();
final String uri = arguments.getUriTemplate();
if (!requestUriManager.isAuthenticatedURI(method, uri)) {
return true;
}
String accessToken = arguments.getParameter("accessToken");
if (accessToken == null) {
accessToken = arguments.getHeader("accessToken");
}
if (accessToken == null) {
accessToken = arguments.getCookieValue("accessToken");
}
if (accessToken == null) {
throw new TokenNotFoundException("Can not get accessToken from cookie");
}
final long userId = authenticationService.verifyAccessToken(accessToken);
arguments.setArgument(UserId.class, userId);
return true;
}
}
