Vue3 Typescript 全局 WebSocket 连接实现指南

在Vue3中使用Typescript来创建全局WebSocket连接，可以按照以下步骤进行：\n\n1. 首先，安装websocket库，可以使用npm或者yarn进行安装：\n\nnpm install websocket\n\n\n2. 在Vue3的项目中创建一个WebSocketService.ts文件，用于处理WebSocket连接的逻辑。\n\ntypescript\nimport { reactive } from 'vue';\nimport WebSocket from 'websocket';\n\nconst WebSocketService = reactive({\n ws: null,\n isConnected: false,\n connect() {\n this.ws = new WebSocket('ws://your-websocket-url'); // 替换成你的WebSocket服务器URL\n this.ws.onopen = () => {\n this.isConnected = true;\n console.log('WebSocket连接已打开');\n };\n\n this.ws.onmessage = (message) => {\n console.log('收到消息:', message.data);\n // 处理收到的消息\n };\n\n this.ws.onclose = () => {\n this.isConnected = false;\n console.log('WebSocket连接已关闭');\n // 可以在此处进行重新连接的逻辑\n };\n },\n send(message: string) {\n if (this.ws && this.isConnected) {\n this.ws.send(message);\n }\n },\n close() {\n if (this.ws && this.isConnected) {\n this.ws.close();\n }\n },\n});\n\nexport default WebSocketService;\n\n\n3. 在需要使用WebSocket的组件中，导入WebSocketService并进行连接、发送消息、关闭连接等操作。\n\nvue\n<template>\n <div>\n <button @click="connect">连接WebSocket</button>\n <button @click="sendMessage">发送消息</button>\n <button @click="close">关闭WebSocket</button>\n </div>\n</template>\n\n<script lang="ts">\nimport { defineComponent } from 'vue';\nimport WebSocketService from './WebSocketService.ts';\n\nexport default defineComponent({\n methods: {\n connect() {\n WebSocketService.connect();\n },\n sendMessage() {\n WebSocketService.send('Hello WebSocket!');\n },\n close() {\n WebSocketService.close();\n },\n },\n});\n</script>\n\n\n这样，你就可以在Vue3中使用Typescript创建全局WebSocket连接了。注意替换WebSocketService.ts中的WebSocket服务器URL为你实际使用的URL。
