碰到难点
1.wss 心跳机制
实现前端和后端双向绑定 只要后端发送了消息 前端通过全局总线去触发你想要的函数。
全局总线
vue3可以全局总线下一个mitt
新建一个eventBus.js
import mitt from "mitt";
const eventBus = mitt();export default eventBus;然后wss新建一个useWebSocket.js
import { ref } from "vue";
import eventBus from "../mixins/eventBus";// 连接状态
export const SocketStatus = {Connecting: "正在连接...", // 表示正在连接，这是初始状态。Connected: "连接已建立", // 表示连接已经建立。Disconnecting: "连接正在关闭", // 表示连接正在关闭。Disconnected: "连接已断开", // 表示连接已经关闭。
};const DEFAULT_OPTIONS = {url: "", // WebSocket URLheartBeatData: "", // 心跳数据heartBeatInterval: 60 * 1000, // 心跳间隔，单位 msreconnectInterval: 5 * 1000, // 断线重连间隔，单位 msmaxReconnectAttempts: 10, // 最大重连次数
};const SocketCloseCode = 1000;export default function useWebSocket(options = {}, onMessageCallback) {//onMessageCallback 处理回调函数 确保在收到消息时候调用const state = ref({options: { ...DEFAULT_OPTIONS, ...options },socket: null,heartBeatSendTimer: null, // 心跳发送定时器heartBeatTimeoutTimer: null, // 心跳超时定时器reconnectAttempts: 0,reconnectTimeout: null,});const status = ref(SocketStatus.Disconnected);// 连接 WebSocketconst connect = () => {disconnect(); // 断开之前的连接status.value = SocketStatus.Connecting;state.value.socket = new WebSocket(state.value.options.url);state.value.socket.onopen = (openEvent) => {console.log("socket连接:", openEvent);status.value = SocketStatus.Connected;startHeartBeat(); // 开始心跳};state.value.socket.onmessage = (msgEvent) => {console.log("socket消息:", msgEvent);if (typeof onMessageCallback === "function") {// onMessageCallback(); // 调用传入的回调函数// 广播消息
//在这边可以不用调用传入的函数 可以直接全局调用函数 懒得改了eventBus.emit("socketMessage", msgEvent.data);eventBus.emit("Messageaa");eventBus.emit("Messagebb");} else {console.error("getDate is not a function");}// if (typeof getDate === "function") {// getDate(); // 调用 getDate 函数// } else {// console.error("getDate is not a function");// }startHeartBeat(); // 收到消息时重新开始心跳};state.value.socket.onclose = (closeEvent) => {console.log("socket关闭:", closeEvent);status.value = SocketStatus.Disconnected;// 非正常关闭，尝试重连if (closeEvent.code !== SocketCloseCode) {reconnect();}};state.value.socket.onerror = (errEvent) => {console.log("socket报错:", errEvent);status.value = SocketStatus.Disconnected;reconnect(); // 连接失败，尝试重连};};// 断开 WebSocketconst disconnect = () => {// 如果 WebSocket 实例存在且处于开放或连接中的状态，则关闭连接。if (state.value.socket && (state.value.socket.OPEN || state.value.socket.CONNECTING)) {console.log("socket断开连接");status.value = SocketStatus.Disconnecting;state.value.socket.close(SocketCloseCode, "normal closure");state.value.socket = null;stopHeartBeat(); // 停止心跳stopReconnect(); // 停止重连}};// 开始心跳检测const startHeartBeat = () => {stopHeartBeat(); // 先清除之前的定时器state.value.heartBeatSendTimer = setTimeout(() => {if (status.value === SocketStatus.Connected) {state.value.socket.send(state.value.options.heartBeatData);console.log("socket心跳发送:", state.value.options.heartBeatData);}// 心跳超时state.value.heartBeatTimeoutTimer = setTimeout(() => {console.log("心跳超时，关闭连接");state.value.socket.close(4444, "heart timeout");}, state.value.options.heartBeatInterval);}, state.value.options.heartBeatInterval);};// 停止心跳检测const stopHeartBeat = () => {if (state.value.heartBeatSendTimer) {clearTimeout(state.value.heartBeatSendTimer);state.value.heartBeatSendTimer = null;}if (state.value.heartBeatTimeoutTimer) {clearTimeout(state.value.heartBeatTimeoutTimer);state.value.heartBeatTimeoutTimer = null;}};// 重连机制const reconnect = () => {// reconnect：如果连接状态不是 Connected 或 Connecting，并且重连尝试次数小于最大值，则尝试重连。if (status.value === SocketStatus.Connected || status.value === SocketStatus.Connecting) {return;}stopHeartBeat(); // 停止心跳if (state.value.reconnectAttempts < state.value.options.maxReconnectAttempts) {console.log("socket重连:", state.value.reconnectAttempts);// 重连间隔，5秒起步，下次递增1秒const interval = Math.max(state.value.options.reconnectInterval, state.value.reconnectAttempts * 1000);console.log("间隔时间：", interval);state.value.reconnectTimeout = setTimeout(() => {if (status.value !== SocketStatus.Connected && status.value !== SocketStatus.Connecting) {connect();}}, interval);state.value.reconnectAttempts += 1;} else {status.value = SocketStatus.Disconnected;stopReconnect(); // 停止重连}};// 停止重连const stopReconnect = () => {if (state.value.reconnectTimeout) {clearTimeout(state.value.reconnectTimeout);state.value.reconnectTimeout = null;}};return {connect,disconnect,status,};
}
重点是这步
state.value.socket.onmessage = (msgEvent) => {console.log("socket消息:", msgEvent);if (typeof onMessageCallback === "function") {// onMessageCallback(); // 调用传入的回调函数// 广播消息
//在这边可以不用调用传入的函数 可以直接全局调用函数 懒得改了eventBus.emit("socketMessage", msgEvent.data);eventBus.emit("Messageaa");eventBus.emit("Messagebb");} else {console.error("getDate is not a function");}然后在自己的组件
import useWebSocket, { SocketStatus } from "@/mixins/useWebSocket";
import eventBus from "@/mixins/eventBus";onMounted(() => {eventBus.on("tenDays", getDate);eventBus.on("socketMessage", getDate); // 监听 WebSocket 消息事件getDate(); // 在组件初始化时调用 getDategetUser(); //为了链接wss});
onUnmounted(() => {eventBus.off("tenDays", getDate);eventBus.off("socketMessage", getDate);disconnect(); // 断开 WebSocket 连接
});我传函数进去了其实不用的 懒得改了 因为 我要接收到数据 好几个函数一起被触发 所以全局总线比较好
const ID = ref("");
const getUser = () => {userInfo().then((res) => {// console.log("用户res", res);localStorage.setItem("userInof", JSON.stringify(res.data.sysUser));ID.value = res.data.sysUser.id;if (ID.value) {console.log("连接WebSocket");// setLoginCookie(); // 设置登录 Cookie（包括 token）connect(); // 连接 WebSocket} // 组件挂载时连接 WebSocket});
};const { connect, disconnect, status } = useWebSocket({url: computed(() => {// const token = Cookie.get("Authorization") || "";return ID.value? `wss://www.tbaowl.com:9992/ws/mini/websocket/${ID.value}`: "";}), // 替换为实际的 WebSocket URLheartBeatData: "ping", // 心跳数据heartBeatInterval: 30000, // 心跳间隔，30秒reconnectInterval: 5000, // 重连间隔，5秒maxReconnectAttempts: 5, // 最大重连次数},getDate
);2.关于弹窗红色预警，逻辑。

难点：
1.一个是关于弹窗如何控制30s显示然后下一个显示，同时伴有警告声音10s消失？
2.数据如果是一个一个传给你或者是一次性多个传给你，怎么办？
3.闪烁动画怎么做？
先处理第三个问题：首先闪烁动画是一个比较图片的盒子，实现一闪一闪的效果
如下
样式可以这样写
闪烁由数据的长度和isTestVisible共同决定
<div class="test" v-if="isTestVisible && warmList.length > 0"></div>.test {width: 972px;height: calc(100vh - 440px);background: url("@/assets/images/image2/warm.png") no-repeat;background-size: 100%;position: absolute;top: 96px;left: 50%;transform: translateX(-50%);animation: blink 1s infinite; // 添加闪烁动画
}
// 闪烁动画
@keyframes blink {0%, // 动画开始时100% { // 动画结束时opacity: 1; // 元素完全可见 (不透明)}50% { // 动画进行到一半时opacity: 0; // 元素完全不可见 (透明)}
}好 现在解决第一个问题。如何让他实现关于弹窗如何控制30s显示然后下一个显示，同时伴有警告声音10s消失。这边就会说明刚才isTestVisible是什么东西了。
首先还是从样式transition-group 来处理这些警告信息的进入和离开动画。
<template><transition-group name="scroll" tag="div" class="warmTanChuan-container"><divv-if="isRunning && currentItem"class="warmTanChuan"ref="warmTanChuan":key="currentItem.id"><div class="title"><img src="@/assets/images/Frame103(91).png" alt="" /><span v-if="currentItem.deviceType == 1">摄像头警告：</span><span v-if="currentItem.deviceType == 2">灵思传感器警告：</span><span v-if="currentItem.deviceType == 3">大华电气设备警告：</span><span v-if="currentItem.deviceType == 4">消防设备警告：</span><span v-if="currentItem.deviceType == 5">车载设备警告：</span><span v-if="currentItem.deviceType == 6">海康消防设备警告：</span><span v-if="currentItem.deviceType == 7">消防传感器警告：</span><span class="time">{{ time }}s</span></div><div class="content_text"><p>{{ currentItem.incidentDescribe }}</p></div></div></transition-group><div class="test" v-if="isTestVisible && warmList.length > 0"></div>
</template>-
transition-group:- 名称为
scroll的transition-group组件，用于处理列表项的动画。 tag="div"设置容器元素为div。- 内部包含一个动态渲染的
div元素，用于显示当前警告信息。
- 名称为
-
div:- 根据
isRunning和currentItem的值来决定是否显示警告信息。 - 使用
:key绑定唯一的标识符，以便transition-group能够正确跟踪元素的变化。
- 根据
-
.warmTanChuan-container:- 定位样式，使警告信息居中显示。
-
.test:- 一个用于测试的
div元素，当isTestVisible为真时显示，带有闪烁动画。
- 一个用于测试的
第一步肯定是拿到数据 如果没有正在播放的数据才可以播
import { ref, onMounted, watch, computed, onUnmounted, nextTick } from "vue";
import { warmEvents } from "@/api/api.js";
import dayjs from "dayjs";
import useWebSocket, { SocketStatus } from "@/mixins/useWebSocket";
import { getSystemData, userInfo } from "@/api/api";
import eventBus from "@/mixins/eventBus";
const warmList = ref([]);
const queue = ref([]); // 用于存储接收到的警告数据的队列const currentIndex = ref(0);
const time = ref(30);
const isRunning = ref(false);
const isTestVisible = ref(true);let audio = new Audio(require("@/assets/warm.mp3"));
audio.hidden = true; // 隐藏音频控件
document.body.appendChild(audio); // 将音频控件添加到页面中const currentItem = computed(() => {return warmList.value.length > 0 ? warmList.value[currentIndex.value] : null;
});const handleMessage = (msg) => {const data = JSON.parse(msg);queue.value.push(data); // 将新数据添加到队列中if (!isRunning.value && !currentItem.value) {// 如果当前没有正在播放的警告信息，开始播放showNextItem();}
};下一条给warnList添加数据 同时queue移除
const showNextItem = () => {if (queue.value.length > 0) {warmList.value.push(queue.value.shift()); // 从队列中取出一条数据并添加到warmListconsole.log("queue.value", queue.value);console.log("warmList.value2222", warmList.value);isRunning.value = true; // 标记为正在播放isTestVisible.value = true;time.value = 30; // 重置时间playAudio();//播放声音startCountDown(); // 开始倒计时} else {isRunning.value = false; // 如果队列为空，停止播放isTestVisible.value = false;}
};播放声音
const playAudio = () => {audio.currentTime = 0;audio.play().catch((error) => {console.error("Error playing audio:", error);});// 设置定时器，10秒后停止音频setTimeout(() => {audio.pause();}, 10000); // 10000毫秒 = 10秒
};开始倒计时
const startCountDown = () => {if (countDown) {clearInterval(countDown); // 清除之前的倒计时定时器}countDown = setInterval(() => {if (isRunning.value) {time.value -= 1;if (time.value <= 0) {clearInterval(countDown);handleAudioEnded();}}}, 1000);
};
const handleAudioEnded = () => {if (queue.value.length > 0) {currentIndex.value++;showNextItem();} else {isRunning.value = false; // 没有更多数据，停止播放isTestVisible.value = false;audio.pause();document.body.removeChild(audio); // 移除音频控件}
};
watch(currentIndex, () => {if (isRunning.value) {if (countDown) {clearInterval(countDown);startCountDown();}}
});因为warmList肯定是有数据的所以再加一个条件isTestVisible来控制闪烁动画。
3.地图部分的数据筛选。

</style>关于下拉框无法置空
这边的难点是关于下拉框是三级联动同时3种筛选选择其中一种的时候，其他两种都必须置为空。难就难在下拉框无法置空踩的坑。后面发现双向绑定还是无法置空 可以重置他们的key
有几个地方需要理解下
关于十进制的用法
// 如果 monthArr.value 是 ['01', '02', '03'] 并且 selectedMonth.value 是 1，那么 month 的值将会是 2。// 如果 monthArr.value 是 [1, 2, 3]，并且 selectedMonth.value 是 1，那么 month 的值将会是 2。parseInt(2, 10) 仍然返回 2。const month = parseInt(monthArr.value[selectedMonth.value], 10);关于一个月的开始和尾巴
// 创建一个日期对象，表示selectedYear.value年seasonStartMonth月的第一天。startTime.value = dayjs(new Date(selectedYear.value, seasonStartMonth, 1)).startOf("month").format("YYYY-MM-DD HH:mm:ss");// 这里0表示该月的最后一天。endTime.value = dayjs(new Date(selectedYear.value, seasonEndMonth, 0)).endOf("month").format("YYYY-MM-DD HH:mm:ss");
