Vue+websocket+stompjs 实时监控坐席状态demo

由于是前后端分离的demo, 程序的后端我不管,我只负责把前端做好,这只是个demo, 还有很多不完善的地方。

2018-01-09新增:
后端的MQ事件结构现在也改了,该demo只能看看了。

打开控制台,输入tm.initWebsocket()后,websocket连接正常。

之后坐席状态改变,可以看到有事件推送过来。

看下整个页面:

最后,这个小小的监控如果用jQuery写,也可以,不过就是太坑了,每次都要去找到Dom元素,再更新DOM,用了Vue这类的框架,页面的dom操作完全不用关心了,真是太舒服了。\(^o^)/

关于stomp的重连

程序后服务端使用RabbitMQ
这里我直接引用我的另一个项目的部分代码,这个没有使用SockJS, 直接使用浏览器原生的WebSocket。
重连的原理很简单,就是检测到断开时,去调用我的reconnectWs方法,这里我也做了重连的次数限制。

initWebSocket: function(callback, errorCallback) {
            callback = callback || function(){};

            if(ws && ws.connected){
                return;
            }

            Config.isManCloseWs = false;

            var url = Config.wsProtocol + Config.SDK + Config.eventPort + Config.eventBasePath + "/websocket";

            if(typeof WebSocket != 'function'){
                alert('您的浏览器版本太太太老了,请升级你的浏览器到IE11,或使用任何支持原生WebSocket的浏览器');
                return;
            }

            try{
                var socket = new WebSocket(url);
            }
            catch(e){
                console.log(e);
                return;
            }


            var wsHeartbeatId = '';

            ws = Stomp.over(socket);

            if(!Config.useWsLog){
                ws.debug = null;
            }

            ws.connect({}, function(frame) {

                Config.currentReconnectTimes = 0;

                var dest = Config.newWsTopic + env.loginId.replace(/\./g,'_');

                var lastEventSerial = '';

                ws.subscribe(dest, function(event) {
                    var eventInfo = {};

                    try{
                        eventInfo = JSON.parse(event.body);
                        delete eventInfo.params;
                        delete eventInfo._type;
                        delete eventInfo.topics;
                    }
                    catch(e){
                        console.log(e);
                        return;
                    }

                    if(lastEventSerial === eventInfo.serial){
                        util.error('Error: event repeat sent !');
                        return;
                    }
                    else{
                        lastEventSerial = eventInfo.serial;
                    }

                    if(Config.useEventLog){
                        util.debugout.log(' ' + JSON.stringify(eventInfo));
                    }

                    eventHandler.deliverEvent(eventInfo);
                });
                callback();

            }, function(frame) {
                // websocket upexpected disconnected
                // maybe network disconnection, or browser in offline
                // this condition will emit wsDisconnected event
                if(Config.isManCloseWs){return;}
                errorCallback();

                util.log(frame);
                util.error(new Date() + 'websocket disconnect');
                // clearInterval(wsHeartbeatId);

                if(Config.currentReconnectTimes < Config.maxReconnectTimes){
                    Config.currentReconnectTimes++;
                    util.reconnectWs();
                }
                else{
                    var errorMsg = {
                        eventName: 'wsDisconnected',
                        msg: 'websocket disconnect'
                    };
                    wellClient.ui.main({
                        eventName:'wsDisconnected'
                    });
                    util.debugout.log('>>> websocket disconnect');

                    wellClient.triggerInnerOn(errorMsg);
                }
            });
        },

        reconnectWs: function(){
            setTimeout(function(){
                util.log('>>> try to reconnect');
                util.debugout.log('>>> try to reconnect');
                util.initWebSocket(function(){},function(){});

            }, Config.timeout * 1000);
        },
