Android - 使用socket io从服务器接收消息

标签: java android socket.io

我正在使用Gottox的Socket.IO-Java-Client开发一个Android应用程序(koush的AndroidAsync)。我没有问题连接到套接字或通过套接字发送消息,但我没有从套接字接收消息或响应。

活动开始通过API接收消息列表,然后打开套接字以发送和接收传出/传入消息。如果我重新启动活动,则会显示任何新消息,但这是通过API - 我需要在活动仍处于打开状态时从套接字接收它们。

这是我的套接字相关代码:

public final void openSocket() {
    try {
        socket = new SocketIO(SERVER_URL);
        socket.connect(this);
        join();
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }
}

public void join() {
    try {
        JSONObject json = new JSONObject();
        json.putOpt("join", mChat.getID());
        socket.emit("join", this, json);
        // socket.emit("join", json);
    } catch (Exception ex) {
        ex.printStackTrace();
    }
}

public void sendMessage() {
    try {
        System.out.println("Send: " + content.getTextWithEmojis());
        JSONObject json = new JSONObject();
        json = prepareJSONObject(json);
        // socket.emit("send", this, json);
        socket.emit("send", json);
        content.setText("");
        addChat(json);
    } catch (JSONException ex) {
        ex.printStackTrace();
    }
}

public void addChat(JSONObject jObject) {
    ChatPost post;
    try {
        post = parseJSONObject(jObject);
        mChatMessages.add(Arrays.asList(new ChatPost[] {post}));
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

@Override
public void onMessage(JSONObject json, IOAcknowledge ack) {
    try {
        Log.i(TAG, "Server said:" + json.toString());

        if(json.has("args")) {
            JSONArray jArray = json.getJSONArray("args");
            JSONObject jObject = jArray.getJSONObject(0);

            ChatPost post;
            post = parseJSONObject(jObject);
            mChatMessages.add(Arrays.asList(new ChatPost[] {post}));
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

@Override
public void onMessage(String data, IOAcknowledge ack) {
    Log.i(TAG, "Server said: " + data);
}

@Override
public void onError(SocketIOException socketIOException) {
    Log.i(TAG, "an Error occured");
    socketIOException.printStackTrace();
}

@Override
public void onDisconnect() {
    Log.i(TAG, "Connection terminated.");
}

@Override
public void onConnect() {
    Log.i(TAG, "Connection established");
}

@Override
public void on(String event, IOAcknowledge ack, Object... args) {
    Log.i(TAG, "Server triggered event '" + event + "'");
    if (args.length > 0)
        Log.i(TAG, "Args '" + args[0].toString() + "'");
    for (Object arg : args)
        Log.i(TAG, "Args '" + arg.toString() + "'");
}

日志:

I/io.socket(9753): > 5:::{"args":[{"join":"101"}],"name":"join"}
I/io.socket(9753): < 1::
I/io.socket(9753): < 5:::{"name":"ready"}
I/io.socket(9753): < 2::
I/io.socket(9753): < 2::
I/io.socket(9753): > 2::
I/io.socket(9753): > 2::
I/io.socket(9753): > 5:::{"args":[{"content":"test","chat_id":"101","user_id":"5"}],"name":"send"}
I/io.socket(9753): < 2::
I/io.socket(9753): > 2::

我收到“加入”的回复,但不是“发送”。我错过了什么吗?

编辑:我尝试使用koush的AndroidAsync,但遇到了同样的问题。
