vue|vue 项目中使用websocket的正确姿势 vue项目中使用websocket的正确姿

1. 在utils下新建websocket.js文件

// import { showInfoMsg, showErrorMsg } from '@/utils/popInfo'import ElementUI from 'element-ui'; function initWebSocket(e) {console.log(e)const wsUri = WS_API + "/webSocket/" + e; this.socket = new WebSocket(wsUri)//这里面的this都指向vuethis.socket.onerror = webSocketOnError; this.socket.onmessage = webSocketOnMessage; this.socket.onclose = closeWebsocket; }function webSocketOnError(e) {ElementUI.Notification({title: '',message: "WebSocket连接发生错误" + e,type: 'error',duration: 0,}); }function webSocketOnMessage(e) {const data = https://www.it610.com/article/JSON.parse(e.data); console.log(data.msgType ==="INFO", data.msgType === "INFO")if (data.msgType === "INFO") {ElementUI.Notification({title: '',message: data.msg,type: 'success',duration: 3000,}); } else if (data.msgType === "ERROR") {ElementUI.Notification({title: '',message: data.msg,type: 'error',duration: 0,}); }}// 关闭websiocketfunction closeWebsocket() {console.log('连接已关闭...')}function close() {this.socket.close() // 关闭 websocketthis.socket.onclose = function (e) {console.log(e)//监听关闭事件console.log('关闭')}}function webSocketSend(agentData) {this.socket.send(agentData); }export default {initWebSocket, close}

如果想刷新重新链接websocket 可以在App.vue页面里添加个钩子函数

mounted() {//当在任一路由页面被刷新时,便是根组件app被从新建立,此时能够进行webSocket重连//从localStorage中获取用户信息,是登陆状态则能够进行webSocket重连let token = localStorage.getItem("token"); if (token) {// userMessage = JSON.parse(userMessage); this.$websocket.initWebSocket(token); }},

客户端主动关闭websocket 在关闭的地方触发函数就可以

logout() {// localStorage.clear(); localStorage.removeItem("token"); this.$websocket.close(); this.$store.dispatch("LogOut").then(() => {location.reload(); }); },
