Question

今天我正在编写一个从Node.js中的服务器接收字符串的应用程序（Android）。套接字连接很好，我可以从Android发送到服务器就好了，但是当涉及从服务器接收时，readUTF（）在读取时停留。以下是要发送和接收的Android代码：

Socket socket = new Socket("10.13.37.129",1337);
                            DataOutputStream dataOutputStream = new DataOutputStream(socket.getOutputStream());
                            JSONObject jsonObject = new JSONObject();
                            jsonObject.put("data", "Tristen");
                            dataOutputStream.writeUTF(jsonObject.toString());
                            DataInputStream dataInputStream = new DataInputStream(socket.getInputStream());
                            System.out.println("Receiving");
                            final byte[] buffer = {};
                            dataInputStream.read(buffer);
                            string = new String(buffer);
                            System.out.println("Received");
                            Runnable runnable1 = new Runnable() {
                                @Override
                                public void run() {
                                    System.out.println("This is the string: " + string);
                                    System.out.println("This is the buffer: " + buffer.length);
                                    System.out.println("This is the buffer.ToString(): " + buffer.toString());
                                    textView.setText(string);
                                }
                            };
                            runOnUiThread(runnable1);

这是发送字符串的服务器代码：

// Add a 'data' event handler to this instance of socket
clientSocket.on('data', function(data) {
    console.log('DATA: ' + data);
    clientSocket.write('Hello\n');
    clientSocket.write('World\n');
});

有人能看出它有什么问题吗？

readUTF()用于读取DataOutputStream.writeUTF().写的字符串。没有其他的。使用read(), BufferedReader.readLine(),等

DataInputStream.readUTF未从Node.js Server接收任何字符串
