安防监控ezhf 2019-06-21
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^)/
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); },
