socket.io-java-client和node.js-握手时出错

我正在尝试开发一个android应用程序，它将连接到node.js服务器。下面是错误消息：

04-28 14:24:52.250: W/System.err(811): io.socket.SocketIOException: Error while handshaking

服务器：

 var http = require('http');
    http.createServer(function (req, res) {
      res.writeHead(200, {'Content-Type': 'text/plain'});
      res.end('Hello World\n');
    }).listen(8881, '192.168.1.107');
    console.log('Server running at http://192.168.1.107:8881/');

客户：

public class RestClientActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        try {
            SocketIO socket = new SocketIO("http://192.168.1.107:8881/");
            socket.connect(new IOCallback() {
                @Override
                public void onMessage(JSONObject json, IOAcknowledge ack) {
                    try {
                        System.out.println("Server said:" + json.toString(2));
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }

                @Override
                public void onMessage(String data, IOAcknowledge ack) {
                    System.out.println("Server said: " + data);
                }

                @Override
                public void onError(SocketIOException socketIOException) {
                    System.out.println("an Error occured");
                    socketIOException.printStackTrace();
                }

                @Override
                public void onDisconnect() {
                    System.out.println("Connection terminated.");
                }

                @Override
                public void onConnect() {
                    System.out.println("Connection established");
                }

                @Override
                public void on(String event, IOAcknowledge ack, Object... args) {
                    System.out
                            .println("Server triggered event '" + event + "'");
                }
            });

            // This line is cached until the connection is establisched.
             socket.send("Hello Server!");
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

知道我做错了什么吗？如果我键入

http://192.168.1.107:8881/

在浏览器中，它将向我显示“Hello World”在页面上，但我无法使用socket.io-java-client库进行连接。

首先如果您尝试使用

socket为您的服务使用rest客户端。io

不是必需的只要坚持使用HTTP服务器，就可以了，在客户端使用HTTPClient

假设您使用这个android socket.io客户端 我也曾与之合作过

尝试使用服务器端套接字io脚本，这是

在服务器端，在您创建HTTP服务器的地方，您不需要配置

socket.io

来监听HTTP服务器的IP:PORT，这是完整的代码吗？是的，这是完整的代码-很抱歉，这个主题对我来说是新的。您知道我可以使用哪个库来连接到服务器吗？

var server = require('http').Server();
var io = require('socket.io')(server);
io.on('connection', function(socket){
  socket.on('message', function(data){
    console.log("Received message : "+data);
    socket.emit("message","echoing back : "+data);
  });
  socket.on('disconnect', function(){
    // client disconnected
   });
});
server.listen(8881,"192.168.1.107");
