SpringBoot+Vue+Openlayers實現(xiàn)地圖上新增和編輯坐標并保存提交_BADAO_LIUMANG_QIZHI的博客-CSDN博客

在上面實現(xiàn)的基礎(chǔ)上，對接海康威視攝像頭實現(xiàn)攝像頭預覽效果。

該型號只支持IE模式取流。

實現(xiàn)

1、去官網(wǎng)-硬件產(chǎn)品-WEB開發(fā)包下載官方示例代碼。

由于這里的設(shè)備不支持websocket取流，所以下載下面的3.0的開發(fā)包。

2、按照上面博客中建表與生成前后端代碼，進而實現(xiàn)對攝像頭參數(shù)的管理。

實現(xiàn)預覽的主要參數(shù)包括Ip、端口號、登錄名、登錄密碼。其他的都是額外加的參數(shù)。

3、勾選攝像頭進行預覽，限制最多選擇四個，否則瀏覽器會卡頓。

??? <el-tablev-loading="loading":data="videoList"@selection-change="handleSelectionChange">

多選事件處理

???? // 多選框選中數(shù)據(jù)handleSelectionChange(selection) {this.openVideoData = [];this.openVideoData = selection;this.ids = selection.map((item) => item.id);this.single = selection.length !== 1;this.multiple = !selection.length;},

需要提前聲明變量

? data() {return {// 遮罩層loading: false,// 選中數(shù)組ids: [],// 非單個禁用single: true,// 非多個禁用multiple: true,

4、點擊預覽按鈕實現(xiàn)跳轉(zhuǎn)到預覽的新標簽頁

??????? <el-buttontype="success"plainicon="el-icon-setting"size="mini":disabled="multiple"@click="videoChange">預覽</el-button>

預覽按鈕的點擊事件

?? // 查看攝像videoChange() {let routeUrl = this.$router.resolve({path: "/carVideo",query: {videoData: JSON.stringify(this.openVideoData),},});if (this.openVideoData.length > 4) {this.$notify({title: "失敗",message: "最多支持預覽選擇4個攝像頭",type: "error",});} else {window.open(routeUrl.href, "_blank");}},

首先校驗最多選擇四個，然后跳轉(zhuǎn)到新的預覽頁面/carVideo。

首先配置路由，打開src/router下的index.js，添加路由

? {path: '/carVideo',component: Layout,component: (resolve) => require(['@/views/system/cameramap/component/video'], resolve),meta: {title: '攝像頭'},hidden: true,},

然后跳轉(zhuǎn)路由時攜帶了要進行預覽的攝像頭參數(shù)this.openVideoData

5、預覽頁面video.vue引入官網(wǎng)的webVideoCtrl.js文件

首先該頁面中需要引入官網(wǎng)的webVideoCtrl.js文件，在根目錄下新建static目錄，將js文件放在該目錄下

引入

import { WebVideoCtrl } from "/static/webVideoCtrl.js";

6、video.vue判斷當前是否為IE/兼容模式

data中獲取請求代理

ua: navigator.userAgent.toLocaleLowerCase(),

created方法中進行判斷并提示

? created() {if (this.ua.match(/msie/) != null || this.ua.match(/trident/) != null) {this.browserType = "IE";this.videoData = JSON.parse(this.$route.query.videoData);if (this.videoData.length <= 1) {this.iWndowType = 1;} else if (this.videoData.length > 1 && this.videoData.length <= 4) {this.iWndowType = 2;}} else {this.$notify({title: "失敗",message: "請在ie模式下查看攝像頭",type: "error",});}},

7、初始化預覽頁面

在mounted中執(zhí)行初始化界面的操作

? mounted() {this.videoChange();},

在方法中

??? videoChange() {setTimeout(() => {this.videoInitPlugin(); // 初始化video界面}, 300);},

調(diào)用videoInitPlugin中校驗是否已經(jīng)安裝插件，插件位置為開發(fā)包中exe文件

校驗是否已經(jīng)安裝插件的方法

??? videoInitPlugin() {this.$nextTick(() => {var iRet = WebVideoCtrl.I_CheckPluginInstall();if (iRet === -1) {// alert("您還未安裝過插件，雙擊開發(fā)包目錄里的WebComponentsKit.exe安裝");this.myFunction();return;}this.initPlugin();});},myFunction() {var r = confirm("您還未安裝過插件，請下載后查看攝像!");if (r == true) {window.location.href = "/WebComponentsKit.exe";} else {}},

如果沒有安裝插件會進行提示并且確定后進行下載，所以將WebComponentsKit.exe

放在代碼中public目錄下

如果已經(jīng)安裝插件則執(zhí)行官方js中初始化插件的方法

??? initPlugin() {WebVideoCtrl.I_InitPlugin("100%", "100%", {bWndFull: true, //是否支持單窗口雙擊全屏，默I_CheckPluginInstalliWndowType: this.iWndowType, //默認展示幾個攝像頭1x1 2x2cbInitPluginComplete: function () {WebVideoCtrl.I_InsertOBJECTPlugin("divPlugin");// 檢查插件是否最新if (WebVideoCtrl.I_CheckPluginVersion() === -1) {return;}},});for (var i = 0; i < this.videoData.length; i++) {this.hkvInfo = this.videoData[i];this.index = i;this.onLogin();}},

然后是遍歷選擇的所有攝像頭進行登錄操作。

8、攝像頭登錄

??? // 登錄async onLogin() {var that = this;that.loginLoading = true;// 登錄設(shè)備WebVideoCtrl.I_Login(that.hkvInfo.ip,that.iProtocol,that.hkvInfo.port,that.hkvInfo.username,that.hkvInfo.password,{async: false,success: (xmlDoc) => {//TODO 獲取通道信息that.getChannelInfo();that.getDevicePort(that.hkvInfo.ip + "_" + that.hkvInfo.port);that.loginLoading = false;this.clickStartRealPlay();},error: function () {that.loginLoading = false;that.$message({showClose: true,message: "登錄失敗",type: "error",});},});},

9、登錄成功后調(diào)用預覽

在登錄成功后直接調(diào)用預覽方法

??? clickStartRealPlay() {console.log("開始預覽", this.index);// 開始預覽var that = this;that.startPlayLoading = true;var szDeviceIdentify = that.hkvInfo.ip + "_" + that.hkvInfo.port;that.startRealPlay(szDeviceIdentify, this.index, that.hkvInfo.channels[0]);that.startPlayLoading = false;},startRealPlay(szDeviceIdentify, iWndIndex, iChannelID) {var that = this;WebVideoCtrl.I_StartRealPlay(szDeviceIdentify, {iRtspPort: that.iRtspPort,iWndIndex: iWndIndex,iChannelID: iChannelID,bZeroChannel: that.bZeroChannel,success: function () {//?? that.$notify({//???? title: "成功",//???? message: "開始預覽通道" + iChannelID + "成功",//???? type: "success",//?? });},error(status, xmlDoc2) {console.log(xmlDoc2); //不能刪除// that.$notify({//?? title: "失敗",//?? message: "開始預覽通道" + iChannelID + "失敗",//?? type: "error",// });if (status === 403) {console.log("szInfo 設(shè)備不支持Websocket取流！");} else {console.log("開始預覽失敗 ", status, xmlDoc2);}},});},

10、在頁面銷毀關(guān)閉時停止預覽并退出登錄

? destroyed() {this.clickStopRealPlay();this.onLogout();},

停止預覽

??? clickStopRealPlay: function () {for (var i = 0; i < = this.index; i++) {setTimeout(this.stopRealPlay(i), 1000);}},stopRealPlay: function (iWndIndex) {var that = this;WebVideoCtrl.I_Stop({iWndIndex: iWndIndex,success: function () {//?? that.$notify({//???? title: "成功",//???? message: "停止預覽窗口" + iWndIndex + "成功",//???? type: "success",//?? });},error: function () {// that.$notify({//?? title: "失敗",//?? message: "停止預覽窗口" + iWndIndex + "失敗",//?? type: "error",// });},});},

退出登錄

??? // 退出onLogout() {this.videoData.forEach((element) => {var szDeviceIdentify = element.ip + "_" + element.port;var iRet = WebVideoCtrl.I_Logout(szDeviceIdentify);if (0 == iRet) {//?? this.$message({//???? showClose: true,//???? message: "退出成功",//???? type: "success",//?? });} else {// this.$message({//?? showClose: true,//?? message: "退出失敗",//?? type: "error",// });}});},

11、完整video.vue示例代碼

<template><div class="video_box"><!-- 攝像頭 --><div id="divPlugin" class="plugin"></div></div> </template><script> import { WebVideoCtrl } from "/static/webVideoCtrl.js"; export default {name: "OpUser",components: {},data() {return {szInfo: "",rowList: {},hkvInfo: {},mySelectWnd: 0, //當前選中的窗口g_bPTZAuto: false,iProtocol: 1,loginLoading: false,startPlayLoading: false,bZeroChannel: false,iRtspPort: 0,index: 0,iWndowType: null,videoData: [],ua: navigator.userAgent.toLocaleLowerCase(),};},created() {if (this.ua.match(/msie/) != null || this.ua.match(/trident/) != null) {this.browserType = "IE";this.videoData = JSON.parse(this.$route.query.videoData);if (this.videoData.length <= 1) {this.iWndowType = 1;} else if (this.videoData.length > 1 && this.videoData.length <= 4) {this.iWndowType = 2;}} else {this.$notify({title: "失敗",message: "請在ie模式下查看攝像頭",type: "error",});}},mounted() {this.videoChange();},destroyed() {this.clickStopRealPlay();this.onLogout();},methods: {getList() {},videoChange() {setTimeout(() => {this.videoInitPlugin(); // 初始化video界面}, 300);},handleSelectionChange() {},submitForm() {},cancel() {},// 登錄async onLogin() {var that = this;that.loginLoading = true;// 登錄設(shè)備WebVideoCtrl.I_Login(that.hkvInfo.ip,that.iProtocol,that.hkvInfo.port,that.hkvInfo.username,that.hkvInfo.password,{async: false,success: (xmlDoc) => {//TODO 獲取通道信息that.getChannelInfo();that.getDevicePort(that.hkvInfo.ip + "_" + that.hkvInfo.port);that.loginLoading = false;this.clickStartRealPlay();},error: function () {that.loginLoading = false;that.$message({showClose: true,message: "登錄失敗",type: "error",});},});},// 退出onLogout() {this.videoData.forEach((element) => {var szDeviceIdentify = element.ip + "_" + element.port;var iRet = WebVideoCtrl.I_Logout(szDeviceIdentify);if (0 == iRet) {//??
