DDPush推送學習筆記（一） 原

一、下載DDPush的jar包並導入到Java項目

二、編寫推送代碼

        Pusher pusher = null;
		try {
            //三個參數分別對應：DDPush服務器IP，DDPush默認推送端口，響應超時
			pusher = new Pusher("192.168.X.X", 9999, 5000);
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		String str = "";
		Scanner scanner = null;
		
		while (!str.equals("bye")) {
			System.out.println("請輸入要發送的消息：");
			scanner = new Scanner(System.in);
			str = scanner.next();
			System.out.println("你輸入的是："+str);
			boolean flag = false;
			try {
                //user1表示要推到的用戶，轉換爲DDPush的uuid
				flag = pusher.push0x20Message(StringUtil.md5Byte("user1"), str.getBytes("UTF-8"));
			} catch (Exception e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
				flag = false;
			}
			System.out.println(flag);
		}

三、編寫接收推送的代碼

1）編寫自定義的TCPClient

public class MyTCPClient extends TCPClientBase{
	
	public MyTCPClient(byte[] uuid) throws Exception {
        //uuid, appid, DDPush服務器IP，DDPush默認接收消息的端口，響應超時
		super(uuid, 1, "192.168.X.X", 9966, 5);
	}

	@Override
	public boolean hasNetworkConnection() {
		// TODO Auto-generated method stub
		return true;
	}

	@Override
	public void onPushMessage(Message msg) {
		// TODO Auto-generated method stub
		if (msg == null) {
			System.out.println("msg is null");
			return;
		}
		
		if (msg.getData() == null || msg.getData().length == 0) {
			System.out.println("msg has no data");
			return;
		}
		String str = null;
		try {
			str = new String(msg.getData(),5,msg.getContentLength(), "UTF-8");
		} catch (UnsupportedEncodingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			str = "Exception";
		}
		System.out.println(str);
	}

	@Override
	public void trySystemSleep() {
		// TODO Auto-generated method stub
		
	}

}

2）調用MyTCPClient

MyTCPClient mClient = null;
			
mClient = new MyTCPClient(StringUtil.md5Byte("user2"));//user2接收消息的用戶

mClient.setHeartbeatInterval(60);
			
mClient.start();

四、啓動DDPush服務端

通過dos命令啓動DDPush服務

> start.bat

五、啓動客戶端程序就可以發送消息了
