binbinYang---android 手机端写Socket服务端和Socket客户端_移动端作为socket 服务端-优快云博客

最近在帮PHP那边做一个测试DEMO 需要我给他发送当前手机IP。。。和写一个在安卓手机上实现的服务端。。。

先说说查看当前手机连接WIFI后IP是多少的代码

public   String getIpAddress(Context context) {
        String IpAddress = null;
        WifiInfo wifiInfo = getWifiInfo(context);
        if (wifiInfo != null) {
            IpAddress = intToIpAddress(wifiInfo.getIpAddress());
        }
        return IpAddress;
    }

    public   String intToIpAddress(long ipInt) {
        StringBuffer sb = new StringBuffer();
        sb.append(ipInt & 0xFF).append(".");
        sb.append((ipInt >> 8) & 0xFF).append(".");
        sb.append((ipInt >> 16) & 0xFF).append(".");
        sb.append((ipInt >> 24) & 0xFF);
        textView.setText("当前我手机IP是---"+sb.toString());
        request(sb.toString());
        return sb.toString();
    }

    /**
     * 获取WifiInfo
     */
    public static WifiInfo getWifiInfo(Context context) {
        WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
        WifiInfo info = null;
        if (null != wifiManager) {
            info = wifiManager.getConnectionInfo();
        }
        return info;
    }

然后创建一个SOCKET服务端

public void ServerReceviedByTcp() {
        // 声明一个ServerSocket对象
        ServerSocket serverSocket = null;
        try {
            // 创建一个ServerSocket对象，并让这个Socket在1989端口监听
            serverSocket = new ServerSocket(2345);
            // 调用ServerSocket的accept()方法，接受客户端所发送的请求，
            // 如果客户端没有发送数据，那么该线程就停滞不继续
            while (true) {
                Socket socket = serverSocket.accept();
                // 从Socket当中得到InputStream对象
                InputStream inputStream = socket.getInputStream();

                byte buffer[] = new byte[1024 *1000];
                int temp = 0;
                // 从InputStream当中读取客户端所发送的数据
                while ((temp = inputStream.read(buffer)) != -1) {
                    System.out.println("收到客户端的消息:"+new String(buffer, 0, temp));
                }
//
//                BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(
//                        socket.getOutputStream()));
//                writer.write("收到消息...\n");
//                writer.flush();
//                System.out.println("服务端:-->收到消息");
            }
            //serverSocket.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

客户端连接

protected void connectServerWithTCPSocket() {

        try {// 创建一个Socket对象，并指定服务端的IP及端口号
            if(clientSocket != null){
                clientSocket.close();
            }
            clientSocket = new Socket("10.2.69.73", 2345);
            boolean isConnected = clientSocket.isConnected();
            System.out.println("-------------------link:" + isConnected);
//            while (true){
//                InputStream inputStream = clientSocket.getInputStream();
//                byte buffer[] = new byte[1024 * 4];
//                int temp = 0;
//                while ((temp = inputStream.read(buffer)) != -1) {
//                    System.out.println("服务端回执:"+new String(buffer, 0, temp));
//                }
//
//
//                try {
//                    Thread.sleep(1000);
//                    System.out.println("sleep.....1秒");
//                }catch (Exception e){
//                    e.printStackTrace();
//                }
//            }


        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
