Question

我正在尝试从使用libgdx作为接口的客户端连接到服务器。我在客户端和服务器上都使用Kryonet。但它不起作用。知道什么是错的吗？

以下是我在客户端中使用的代码：

override func viewWillAppear(_ animated: Bool) {

    let idxPath = IndexPath(row: savedSelection, section: 0)

    let cell = collectionView?.cellForItem(at: idxPath)
    cell?.isSelected = true
    collectionView?.scrollToItem(at: idxPath, at: UICollectionViewScrollPosition.centeredHorizontally, animated: false)

}

这是服务器代码：

     Client client = new Client();
        Kryo kryo = client.getKryo();
        kryo.register(String.class);
        client.start();
        new Thread() {
            public void run() {
                try {
                    client.connect(5000, "localhost", 54555, 54777);
                    client.addListener(new Listener() {
                        public void received(Connection connection, Object object) {
                            if (object instanceof String) {
                                String response = (String) object;
                                System.out.println(response);
                            }
                        }
                    });
                } catch (IOException e) {
                    Log.warn("expection", e);
                }
            }
        }.start();
   client.sendTCP("Hey There");

这是我得到的错误：

Server server = new Server();
    Kryo kryo = server.getKryo();
            kryo.register(String.class);
            server.start();
            try {
                server.bind(54555, 54777);
            } catch (IOException e) {
                e.printStackTrace();
            }

            server.addListener(new Listener() {
                public void received (Connection connection, Object object) {
                   if (object instanceof String) {
                      String request = (String)object;
                      System.out.println("Server"+request);

                      String response = "Login succes";
                      connection.sendTCP(response);
                   }
                }
             });

好的，我认为这段代码已经修好了：

服务器：

server = new Server();
    Kryo kryo = server.getKryo();
    kryo.register(SRq.class);
    server.start();
    try {
        server.bind(54555, 54777);
    } catch (Exception e) {
        System.err.println("Failed to bind to port!");
    }
    server.addListener(new Listener() {
        @Override
        public void received(Connection connection, Object object) {
            if(object instanceof SRq) {
                System.out.println("Server " +  ((SRq) object).data);
                SRq sRq = new SRq();
                sRq.data = "Data";
                connection.sendTCP(sRq);
            }
        }
    });

客户端：

client = new Client();
    Kryo kryo = client.getKryo();
    kryo.register(SRq.class);
    client.start();
    try {
        client.connect(6000, "localhost", 54555, 54777);
    } catch (Exception e) {
        System.err.println("Failed to connect to server!");
    }
    client.addListener(new Listener() {
        @Override
        public void received(Connection connection, Object object) {
            if(object instanceof SRq) {
                Gdx.app.log("Client", ((SRq) object).data);
            }
        }
    });
    System.out.println("Connected to server!");

    SRq sRq = new SRq();
    sRq.data = "Log in";
    client.sendTCP(sRq);

要记住的事情：

SRq.class只是一个内部有公共String的课程
确保在客户端和服务器中使用相同的KryoNet版本。我用了kryonet-2.21-all。下载jar，在你的核心文件夹中创建一个名为libs的文件夹，将jar放入其中，然后将其添加到build.gradle（核心依赖项中）：compile fileTree(dir: 'libs', include: '*.jar')

将客户端连接到服务器Kryonet和Libgdx
