一、websocket

• code

return {// 用于存储 WebSocket 返回的状态数据statusList: [],},mounted() {this.setupWebSocket();this.startBlinking();},methods: {setupWebSocket() {// 创建 WebSocket 连接const socket = new WebSocket('ws://xxx.xxx:xxx/xxx');// WebSocket 连接成功时触发socket.onopen = () => {console.log('WebSocket connection established.');};// WebSocket 收到消息时触发socket.onmessage = (event) => {console.log('Message from server:', event.data);try {// 解析服务器发送的数据const data = JSON.parse(event.data);// 更新状态列表，每个项初始化为灰色this.statusList = data.map((item) => ({...item,isGray: true, // 初始为灰色}));} catch (error) {console.error('Failed to parse message:', error);}};// WebSocket 连接关闭时触发socket.onclose = () => {console.log('WebSocket connection closed.');};// WebSocket 连接发生错误时触发socket.onerror = (error) => {console.log('WebSocket error:', error);}
