Android WebSocket開發

標籤：依賴   add   監聽   exce   end   ESS   code   sage   串連   

一，在模組build.gradle中添加webSocket的依賴包

//WebSocket 依賴包implementation ‘com.neovisionaries:nv-websocket-client:2.2‘

二，串連webSocket

  try {          WebSocket ws = new WebSocketFactory().createSocket(url, CONNECT_TIMEOUT) //ws地址，和設定逾時時間                    .setFrameQueueSize(FRAME_QUEUE_SIZE)//設定幀隊列最大值為5                    .setMissingCloseFrameAllowed(false)//設定不允許服務端關閉串連卻未發送關閉幀                    .addListener(wsListener = new WsListener())//添加回調監聽                    .connectAsynchronously();//非同步串連        } catch (IOException e) {            e.printStackTrace();        }

三、添加內部類，實現回調監聽

/**     * 繼承預設的監聽空實現WebSocketAdapter,重寫我們需要的方法     * onTextMessage 收到文字資訊     * onConnected 串連成功     * onConnectError 串連失敗     * onDisconnected 串連關閉     */    class WsListener extends WebSocketAdapter {        @Override        public void onTextMessage(WebSocket websocket, String text) throws Exception {            super.onTextMessage(websocket, text);            logger.info(text);            String[] msgs = text.split("\\|");            if (msgs.length >= 2) {                NotificationShow(msgs[0], msgs[1]);                sendReceiveMessageBroadcast(msgs[0], msgs[1]);            }        }        @Override        public void onConnected(WebSocket websocket, Map<String, List<String>> headers)                throws Exception {            super.onConnected(websocket, headers);            logger.info("串連成功");        }        @Override        public void onConnectError(WebSocket websocket, WebSocketException exception)                throws Exception {            super.onConnectError(websocket, exception);            logger.warning("串連錯誤：" + exception.getMessage());        }        @Override        public void onDisconnected(WebSocket websocket, WebSocketFrame serverCloseFrame, WebSocketFrame clientCloseFrame, boolean closedByServer)                throws Exception {            super.onDisconnected(websocket, serverCloseFrame, clientCloseFrame, closedByServer);            logger.warning("中斷連線");        }    }
