Android 自定义C/S两用Socket框架

两用框架

代码

public class mSocket {
    private ServerSocket connection;
    private Socket socket;
    private ObjectOutputStream output;
    private ObjectInputStream input;
    private int port,backlog;
    private String ip;

    public mSocket() {
    }

    public mSocket(int port, int backlog) {
        this.port = port;
        this.backlog = backlog;
        runServer();
    }

    public mSocket(String ip,int port) {
        this.port = port;
        this.ip = ip;
    }

    private void runServer() {
        try {
            connection = new ServerSocket(port ,backlog);
            socket = connection.accept();
            output = new ObjectOutputStream(socket.getOutputStream());
            input = new ObjectInputStream(socket.getInputStream());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public boolean buildConnection() {
        try {
            socket = new Socket(InetAddress.getByName(ip), 8848);
            input = new ObjectInputStream(socket.getInputStream());
            output = new ObjectOutputStream(socket.getOutputStream());
        } catch (IOException e) {
            e.printStackTrace();
            return false;
        }
        return true;
    }


    public String getMessage() {
        String s = "";
        try {
            s = input.readObject() + "";
        } catch (IOException | ClassNotFoundException e) {
            e.printStackTrace();
        }
        return s;
    }

    public void sendMessage(final Object object) {
        new Thread(new Runnable() {
            @Override
            public void run() {
                try {

                    e.printStackTrace();
                }
            }
        }).start();
    }

    public String getIPAddress(Context context) {
        NetworkInfo info = ((ConnectivityManager) context
                .getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo();
        if (info != null && info.isConnected()) {
            if (info.getType() == ConnectivityManager.TYPE_MOBILE) {//当前使用2G/3G/4G网络
                try {
                    //Enumeration<NetworkInterface> en=NetworkInterface.getNetworkInterfaces();
                    for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements(); ) {
                        NetworkInterface intf = en.nextElement();
                        for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements(); ) {
                            InetAddress inetAddress = enumIpAddr.nextElement();
                            if (!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet4Address) {

                            }
                        }
                    }
                } catch (SocketException e) {

                }

            } else if (info.getType() == ConnectivityManager.TYPE_WIFI) {//当前使用无线网络

            }
        } else {

        }
        return null;
    }

    private static String intIP2StringIP(int ip) {
        return (ip & 0xFF) + "." +
                ((ip >> 8) & 0xFF) + "." +
                ((ip >> 16) & 0xFF) + "." +
                (ip >> 24 & 0xFF);
    }
}

用法

创建一个服务端

mSocket server = new mSocket(8848,10);

传入“端口号”+“backlog”参数创建服务器实例,并自动开始监听客户端连入参数。
注：必须在子线程中启用。

创建一个客户端

mSocket client = new mSocket("ip",8848);

传入“ip”+”端口号“参数创建客户端实例。

client.buildConnection();

创建连接的方法，返回true时连接成功，返回false连接失败。
注：必须在子线程中启用

获取信息流

String smessage = client.getMessage();

注：必须在子线程中启用

发送数据流

client.sendMessage("message");

可发送对象类，无需在子线程中使用。

获取本机IP

 String ip = new mSocket().getIPAddress(context);

注：需要添加以下权限

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
 <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
 <uses-permission android:name="android.permission.INTERNET"/>
