VUE3接入海康威视web插件

接入海康的web插件实现在网页端直接表现摄像头监控画面，此办理方案必要在用户电脑上安装exe插件。

web插件下载

起首在官网下载海康插件，打开demo文件夹可以看到必要用到的js和bin目次下的exe插件。

插件导入

安装HCWebSDKPlugin.exe到电脑中，然后在项目标index.html中导入必要使用的js文件，由于jsVideoPlugin-1.0.0.min.js是用于控制摄像头等功能，此处我们仅必要获取监控画面，因此按现实需求引入。

<body>
<div id="app"></div>
<script src="/jquery-1.7.1.min.js"></script>
<script id="videonode" src="/webVideoCtrl.js"></script>
<script type="module" src="/src/main.js"></script>
</body>

复制代码

插件使用

在项目中引入插件后，即可在组件页面实现初始化，由于在script标签中引入，因此对象存在全局变量，在组件中直接使用即可。
必要先进行初始化，然后再登录摄像头，此处提供简单实现。

初始化插件

const startPlugin = () => {
return new Promise((resolve, reject) => {
WebVideoCtrl.I_InitPlugin({
iWndowType: 2,
bWndFull: true, //是否支持单窗口双击全屏，默认支持 true:支持 false:不支持
cbInitPluginComplete: function () {
WebVideoCtrl.I_InsertOBJECTPlugin("divPlugin").then(() => {
// 检查插件是否最新
resolve();
WebVideoCtrl.I_CheckPluginVersion().then((bFlag) => {
if (bFlag) {
// 提示用户安装最新的HCWebSDKPlugin.exe
}
});
}, () => {
reject();
// 初始化失败，提示用户安装最新的HCWebSDKPlugin.exe
});
}
});
})
}

复制代码

登录海康相机

// 根据实际情况修改相机配置
const cameraList = [
{
"ip": "xxx.xxx.xxx.xxx",
"protocol": 1,
"port": "80",
"userName": "admin",
"password": "123456"
},
{
"ip": "xxx.xxx.xxx.xxx",
"protocol": 1,
"port": "80",
"userName": "admin",
"password": "123456"
},
{
"ip": "xxx.xxx.xxx.xxx",
"protocol": 1,
"port": "80",
"userName": "admin",
"password": "123456"
},
{
"ip": "xxx.xxx.xxx.xxx",
"protocol": 1,
"port": "80",
"userName": "admin",
"password": "123456"
}
]
// 登录单个摄像头
const login = (config) => {
return new Promise((resolve, reject) => {
const { ip, protocol, port, userName, password } = config;
WebVideoCtrl.I_Login(ip, protocol, port, userName, password, {
success: () => {
resolve();
},
error: () => {
console.log("登录失败");
reject();
}
})
})
}
const cameraListLogin = () => {
const promiseMap = cameraList.map((item) => {
return login(item);
})
return Promise.all(promiseMap);
}

复制代码

获取画面

// 获取单个画面
const preview = (config) => {
return new Promise((resolve, reject) => {
const { ip, port, window } = config;
WebVideoCtrl.I_StartRealPlay(`${ip}_${port}`, {
async: true,
timeout: 900,
iWndIndex: window,
iChannelID: 1,
bZeroChannel: false,
iStreamType: 2,
success: () => {
resolve();
},
error: () => {
reject();
console.log("预览失败");
}
})
})
}
const cameraListPreview = () => {
const promiseMap = cameraList.map((item, index) => {
return preview({ ...item, window: index });
})
return Promise.all(promiseMap);
}

复制代码

停止及销毁

const stopAllPreview = (callBack) => {
WebVideoCtrl.I_StopAllPlay().then(() => callBack?.());
}
const loginOut = () => {
cameraList.forEach((item) => {
WebVideoCtrl.I_Logout(`${item.ip}_${item.port}`)
})
}
const breakDom = () => {
WebVideoCtrl.I_DestroyPlugin();
}
