generateUniqueRandomKey 方法，具体参考上一篇文章 ，csdn链接: https://blog.csdn.net/weixin_44180579/article/details/140708809

// useWebSocket.ts  // useWebSocket.js import { ref, onMounted, onBeforeUnmount } from "vue"; import { generateUniqueRandomKey } from "@/utils/utils";  //具体参考上一篇文章   export default function useWebSocket(   url: string,   onMessageCallback: any,   onErrorCallback = (error: any) => {} ) {   // 状态管理   const socketRef = ref(null);   const isConnected = ref(false);   const reconnectAttempts = ref(0);   // 最大重连次数   const maxReconnectAttempts = 5;   // 重连间隔时间，单位毫秒   const reconnectInterval = 2000;   //每次进页面，生成唯一标识符   const uniqueKey = generateUniqueRandomKey(12);    // 初始化WebSocket连接   const initWebSocket = () => {     // 拼接12位唯一标识符     let newUrl = url + "/" + uniqueKey;     socketRef.value = new WebSocket(newUrl);      socketRef.value.onopen = () => {       isConnected.value = true;       console.log("----------websocket连接成功----------");       reconnectAttempts.value = 0; // 成功连接后重置重连尝试次数     };      socketRef.value.onerror = (error: any) => {       onErrorCallback(error);     };      socketRef.value.onclose = (event: any) => {       isConnected.value = false;       //断线重连       if (reconnectAttempts.value < maxReconnectAttempts) {         setTimeout(initWebSocket, reconnectInterval);         reconnectAttempts.value++;       } else {         console.log("----------websocket连接断开，超出最大重连次数----------");       }     };      socketRef.value.onmessage = (event: any) => {       onMessageCallback(JSON.parse(event.data));     };   };    // 断开连接   const closeWebSocket = () => {     if (socketRef.value && socketRef.value.readyState === 1) {       // 禁止断线重连       reconnectAttempts.value = 6;       socketRef.value.close();       isConnected.value = false;     }   };    // 发送消息   const sendMessage = (data: any) => {     if (socketRef.value && socketRef.value.readyState === 1) {       socketRef.value.send(JSON.stringify(data));     } else {       console.error("socket连接异常--------------");     }   };    // 生命周期钩子   onMounted(() => {     initWebSocket();   });      //页面销毁前，注销关闭socket连接   onBeforeUnmount(() => {     closeWebSocket();   });    // 返回暴露的方法和状态   return {     isConnected,     sendMessage,   }; } 

useWebSocket使用方法：

import useWebSocket from "./useWebSocket"; const socketUrl = 'ws://xxxxxxxxx'  //websocket连接 const { isConnected, sendMessage } = useWebSocket(   socketUrl,   (message: any) => {     // isConnected socket连接状态 true false     // sendMessage 数据推送方法      //向成功连接的服务端推送数据       sendMessage({ filed:'hello' })   } );
