Angular5集成eventbus的示例代码 1.package.json中 "dependencies": { ... "vertx3-eventbus-client": "3.5.2", }, 然后 npm install,或者: npm install vertx3-eventbus-client@3.5.2 2.angular-cli.json中 "scripts": [ ... "../node_modules/vertx3-eventbus-client/vertx-eventbus.js" ], 3.创建一个eventbus.service.ts用来通信 导入eventbus: import { EventBus } from 'vertx3-eventbus-client'; 声明eventbus: declare var EventBus: any; 4.创建eventbus实例,监听接口以及发送消息 //创建实例 var eb = new EventBus('http://localhost:8080/eventbus'); eb.onopen = function() { //注册监听器用来接受消息 eb.registerHandler('some-address', function(error, message) { console.log('received a message: ' + JSON.stringify(message)); }); //发送消息 eb.send('some-address', {name: 'tim', age: 587}); } 更多信息请参考这里 http://vertx.io/docs/vertx-web/java/ 注: 对于需要发送消息来接受的消息,需要先监听,然后再发送消息。 对于一直推送的消息,不需要发送。 代码实例如下: RegisterHandler(key, id, callback) { const address = '***.' + key + '.' + id; if (typeof (this.eventBus[key]) === 'undefined' || !this.eventBus[key]) { this.eventBus[key] = new EventBus(environment.eventbusUrl); } if (this.eventBus[key].state === EventBus.OPEN) { this.eventBus[key].registerHandler(address, callback); } else { const $this = this; this.eventBus[key].onopen = function () { $this.eventBus[key].registerHandler(address, callback) } } } Send(key, id) { var data = ''; const address = ***.' + key + '.' + id; if (typeof (this.eventBus[key]) === 'undefined' || !this.eventBus[key]) { this.eventBus[key] = new EventBus(environment.eventbusUrl); } if (this.eventBus[key].state === EventBus.OPEN) { this.eventBus[key].send(address, data) } else { const $this = this; this.eventBus[key].onopen = function () { $this.eventBus[key].send(address, data) } } } closeEventBus(key) { if (typeof (this.eventBus[key]) !== 'undefined' && this.eventBus[key] && this.eventBus[key].state === EventBus.OPEN) { this.eventBus[key].close(); } this.eventBus[key] = null; } 在组件ngOnDestroy中调用closeEventBus关闭eventbus。 以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持中文源码网。
