Vertx 3 - SockJS 套接字打开取消

Question

我创建了一个新的 Verticle，它应该响应 HTTP 请求和 SockJS 桥接事件。基于这个问题 and vert.x manual https://vertx.io/docs/vertx-web/java/#_sockjs 我创建了这段代码：

Java:

    @Override
    public void start(Future<Void> startFuture) throws Exception {
        startHttpServer(startFuture);
        startSockJSHandler();
    }

    private void startHttpServer(Future<Void> startFuture) {
        HttpServer server = vertx.createHttpServer(new HttpServerOptions());
        server.requestHandler(req -> {
            System.out.println("[" + new Date().toString() + "] Request #" + ++requestCount);
            if (req.path().contains("http")) {
                req.response().putHeader("Access-Control-Allow-Origin", "*").end("req_num: " + requestCount);
            }
        }).listen(8080, ar -> startFuture.handle(ar.mapEmpty()));
    }

    private void startSockJSHandler() {
        Router router = Router.router(vertx);
        SockJSHandlerOptions sockJSOptions = new SockJSHandlerOptions().setHeartbeatInterval(2000);
        SockJSHandler sockJSHandler = SockJSHandler.create(vertx, sockJSOptions);
        BridgeOptions bridgeOptions = new BridgeOptions();
        bridgeOptions.addInboundPermitted(new PermittedOptions().setAddressRegex(".*")).addOutboundPermitted(new PermittedOptions().setAddressRegex(".*"));
        sockJSHandler.bridge(bridgeOptions, be -> {
            System.out.println("BRIDGE EVENT: " + be.type().toString());
        });
        router.route("/eventbus/*").handler(sockJSHandler);
    }

Java编写事件总线客户端脚本：

var sock = new SockJS('http://localhost:8080/eventbus/');

sock.onopen = function() {
  console.log('open');
  sock.send('test');
};

sock.onmessage = function(e) {
  console.log('message', e.data);
  sock.close();
};

sock.onclose = function() {
  console.log('close');
};

HTTP request/response 工作正常，但 SockJS 事件不行。在网络浏览器 'Network' 模块中，我只看到一个 SockJS 请求 (http://localhost:8080/eventbus/info)。 'pending' 状态 8 秒，此后状态更改为 'closed'（最后调用方法 onclose()）。

我是不是做错了什么？

HttpServer 必须将请求委托给 Router。否则什么也不会发生。通常，它被配置为将所有请求委托给 Router.

server.requestHandler(router::accept).listen(8080);
