大气建站工作室网站源码seo服务哪家好

1、安装sockjs-client和stompjs

import SockJS from 'sockjs-client/dist/sockjs.min.js'
import Stomp from 'stompjs'

2、连接后台

let base_url = '/api/****'
//创建STOMP连接
let socket = new SockJS(sockUrl)
// 获取STOMP子协议的客户端对象
this.stompClient = Stomp.over(socket);
// 心跳发送频率
this.stompClient.heartbeat.outgoing = 60000;
// 心跳接收频率
this.stompClient.heartbeat.incoming = 120000;
// 调用.connect方法连接Stomp服务端进行验证
this.stompClient.connect({}, (frame) => {console.log('Connected: ' + frame);// 订阅服务端提供的某个topic  如用户idthis.stompClient.subscribe('/topic/***/' + this.$route.params.id, (frame) => {console.log('Received message:', JSON.stringify(frame.body));})
});

3、vite.config.ts 配置反向代理

原因：SockJS 使用https和http 传输

  // 服务端渲染server: {port: env.VITE_PORT, // 端口号host: "0.0.0.0",open: env.VITE_OPEN === 'true',// 本地跨域代理. 目前注释的原因：暂时没有用途，server 端已经支持跨域proxy: {['/api']: {target: 'http://*****/api',ws: false,rewrite: (path) => path.replace(new RegExp(‘^/api‘), ''),},}}

4、导出并实时通信

import WebSocketService from '@/utils/websocket'
const exportLoading = ref(false)  //异步导出加载中
const exportData = ref(false)     //导出结果提示
// 异步导出
const handleAsynExport = async () => {exportLoading.value = truetry {await AsynExportApi.exportSales(queryParams.value)if (WebSocketService?.stompClient == null) {// 建立 Websocket连接，  /topic/***/${id}  是后端提供的const destination = `/topic/***/${id}`WebSocketService.connect(destination, handleMessage)}} finally {setTimeout(() => {if (!exportData.value) {ElNotification.error({title: '提示',message: '导出失败，请稍后重试'})}exportLoading.value = false}, 3000)}
//弹窗下载链接
const handleMessage = (data: any) => {exportData.value = trueexportLoading.value = falseElNotification.success({title: '提示',message: h('p', null, [h('span', null, data.fileName + '加载成功，请'),h('a',{style: 'color: teal;cursor:pointer;text-decoration: underline;',onClick: () => {location.replace(data.filePath)}},'下载')])})
}//页面切换后断开连接
useRouter().afterEach(() => {if (WebSocketService?.stompClient !== null) {//断开Websocket连接WebSocketService.disconnect()}
})
