java Vert。x身份验证缺少权限将产生500而不是403

Question

我正在用Java实现我的AuthHandler，它与添加到每个路由的正常权限一起工作。它工作得很好-它可以检测用户是否未通过必填字段，并可以告诉用户是否允许访问路由。但如果我试图进入一条基于失踪的权威的禁止路线。x响应为500-内部服务器错误，而不是403-禁止

为什么会这样？我该如何修复它

下面是一些可能会有所帮助的代码片段

// MyUserImpl
@Override
    protected void doIsPermitted(String authority, Handler<AsyncResult<Boolean>> resultHandler) {
        //TODO: make call to token to check permissions using crn and iamtoken
        if (this.token.contains(authority)) {
            resultHandler.handle(Future.succeededFuture(true));
        } else {
            log.info("User is not authorized", token, authority);
            resultHandler.handle(Future.failedFuture(new AuthorizationException(authority)));
        }
    }

// MyAuthProviderImpl
@Override
    public void authenticate(JsonObject authInfo, Handler<AsyncResult<User>> resultHandler) {
        String token = authInfo.getString("iamToken");
        if (this.validate(token)) {
            resultHandler.handle(Future.succeededFuture(new TaskUserImpl(token)));
        } else {
            log.info("User cannot be authenticated", token);
            resultHandler.handle(Future.failedFuture(new AuthenticationException()));
        }
    }

// MyAuthHandlerImpl
public void parseCredentials(RoutingContext ctx, Handler<AsyncResult<JsonObject>> handler) {
        this.parseAuthorization(ctx, false, parseAuthorization -> {
            if (parseAuthorization.failed()) {
                log.info("No Auth token was provided");
                handler.handle(Future.failedFuture(parseAuthorization.cause()));
                final String token = parseAuthorization.result();
                handler.handle(Future.succeededFuture(
                        new JsonObject()
                            .put("iamToken", iamToken)
                ));
        });
    }
