Android developpement,Gottox socket.io-java-client:file not fount Exception /socket.io/1/

Question

这是我的问题:

我一直在尝试使用socket.io-java-client作为Android应用程序,但我最终遇到握手错误(见下文).

这是我的应用程序源代码:

public void runIO(){
    try {
        SocketIO socket = new SocketIO("http://192.168.1.60:1337");
        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();
    }
}

和我的Node.js/Socket.io:

    var app = require('http').createServer(handler)
    var io = require('socket.io')(app); 
    var fs = require('fs');

    app.listen(1337);

    function handler (req, res) {
      fs.readFile(__dirname + '/index.html',
      function (err, data) {
        if (err) {
          res.writeHead(500);
          return res.end('Error loading index.html');
        }

        res.writeHead(200);
        res.end(data);
      });
    }

    io.on('connection', function (socket) {
      socket.emit('news', { hello: 'world' });
      socket.on('my other event', function (data) {
        console.log(data);
      });
    });

我收到以下错误:

    06-09 03:59:53.955: W/System.err(11738): io.socket.SocketIOException: Error while handshaking
    06-09 03:59:53.965: W/System.err(11738):    at io.socket.IOConnection.handshake(IOConnection.java:322)

    06-09 03:59:53.975: W/System.err(11738):    at io.socket.IOConnection.handshake(IOConnection.java:313)

在它运行的浏览器上,页面在http://192.168.1.60:1337/socket.io/1/返回以下消息(通过浏览器):

{"code":0,"message":"Transport unknown"}

我不知道该怎么办才能让它发挥作用...请帮忙:x

感谢:D

编辑:

正如Larky所说,我不得不将我的Socket.io版本降级为0.9.16.它就像一个带有以下节点代码的魅力:

    var io = require('socket.io').listen(80); 

    io.on('connection', function (socket) {
      socket.emit('news', { hello: 'world' });
      socket.on('my other event', function (data) {
        console.log(data);
      });
    });

Answer 1

我今天通过在服务器端(早期版本的socket.io Node模块)恢复到早期版本的socket.io来解决了这个问题.协议可能改变了吗？

去做这个:

1. 删除node_modules文件夹中的socket.io文件夹.

2. 在控制台类型上:

npm install socket.io@0.9.16

应该这样做......它对我有用:)

(显然这并没有完全解决问题,但早期版本的socket.io对我来说对我来说很好)
