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https://stackoverflow.com/questions/41516328和vert.x manual https://vertx.io/docs/vertx-web/java/#_sockjs我创建了这段代码：

爪哇：

    @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);
    }

JavaScript eventbus客户端：

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请求/响应正常，但SockJS事件没有。在Web浏览器“网络”模块中，我只看到一个SockJS请求（http://localhost:8080/eventbus/info）。处于“待定”状态的8秒，此后状态变为“已关闭”（最后调用onclose（）方法。）

我做错了吗？

Answer 1

HttpServer必须将请求委托给Router。否则没有任何反应通常，它被配置为将所有请求委托给Router。

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

请参阅文档中的Basic Vert.x-Web concepts。

Vertx 3 - SockJS套接字打开已取消
