3.1 在海康威视的官网进行下载开发包

https://open.hikvision.com/download/5cda567cf47ae80dd41a54b3?type=10&id=4c945d18fa5f49638ce517ec32e24e24

3.2 配置自己的webVideo.js和html

（1）新建webVideo.js文件，assets/script/webVideo.js，内容如下：

export function WebVideo() {
    this.g_iWndIndex = 0
    this.szDeviceIdentify = ''
    this.deviceport = ''
    this.rtspPort = ''
    this.channels = []
    this.ip = ''
    this.port = '80'
    this.username = ''
    this.password = ''
    this.init = function(ip, username, password) {
        this.ip = ip
        this.username = username
        this.password = password
        // var self = this
        // 检查插件是否已经安装过
        // var iRet = WebVideoCtrl.I_CheckPluginInstall();
        // if (-1 == iRet) {
        //     alert("您还未安装过插件，双击开发包目录里的WebComponentsKit.exe安装！");
        //     return;
        // }
        // 初始化插件参数及插入插件
        WebVideoCtrl.I_InitPlugin(454, 315, {
            szColorProperty: 'plugin-background:#102749; sub-background:#102749; sub-border:#18293c; sub-border-select:red',
            bWndFull: true, // 全屏
            // iPackageType: 2,
            iWndowType: 1, //分屏
            bNoPlugin: true, // 支持无插件
            cbInitPluginComplete: function () {
                WebVideoCtrl.I_InsertOBJECTPlugin("divPlugin");
            }
        });
    }
    // 登录
    this.clickLogin = function () {
        var self = this
        if ("" == self.ip || "" == self.port) {
            return;
        }
        debugger
        self.szDeviceIdentify = self.ip + "_" + self.port;
        WebVideoCtrl.I_Login(self.ip, 1, self.port, self.username, self.password, {
            success: function (xmlDoc) {        
                setTimeout(function () {
                    console.log('登录成功');
                    self.getChannelInfo();
                    self.getDevicePort();
                }, 10);
                setTimeout(function() {
                    self.clickStartRealPlay()
                }, 500)
            },
            error: function (status, xmlDoc) {
                console.log('登录失败');
            }
        });
    }
    // 退出
    this.clickLogout = function() {
        var self = this
        self.channels = []
 
        if (null == self.szDeviceIdentify) {
            return;
        }
        var iRet = WebVideoCtrl.I_Logout(self.szDeviceIdentify);
        if (0 == iRet) {
            self.getChannelInfo();
            self.getDevicePort();
        }
    }
    // 获取通道
    this.getChannelInfo = function() {
        var self = this
        self.channels = []
        if (null == self.szDeviceIdentify) {
            return;
        }
        // 模拟通道
        WebVideoCtrl.I_GetAnalogChannelInfo(self.szDeviceIdentify, {
            async: false,
            success: function (xmlDoc) {
                var oChannels = $(xmlDoc).find("VideoInputChannel");
                $.each(oChannels, function (i) {
                    var id = $(this).find("id").eq(0).text(),
                        name = $(this).find("name").eq(0).text();
                    if ("" == name) {
                        name = "Camera " + (i < 9 ? "0" + (i + 1) : (i + 1));
                    }
                    self.channels.push({
                        id: id,
                        name: name
                    })
                });
                console.log('获取模拟通道号成功')
            },
            error: function (status, xmlDoc) {
                console.log('获取模拟通道号失败')
            }
        });
    }
    // 获取端口
    this.getDevicePort = function() {
        var self = this
        if (null == self.szDeviceIdentify) {
            return;
        }
        var oPort = WebVideoCtrl.I_GetDevicePort(self.szDeviceIdentify);
        if (oPort != null) {
            self.deviceport = oPort.iDevicePort;
            self.rtspPort = oPort.iRtspPort;
        }
        console.log('获取端口号成功')
    }
    
    // 开始预览
    this.clickStartRealPlay = function() {
        var self = this
        var oWndInfo = WebVideoCtrl.I_GetWindowStatus(self.g_iWndIndex),
            iChannelID = self.channels[0].id
    
        if (null == self.szDeviceIdentify) {
            return;
        }
        var startRealPlay = function () {
            WebVideoCtrl.I_StartRealPlay(self.szDeviceIdentify, {
                iChannelID: iChannelID,
                bZeroChannel: false,
                iStreamType: 2,
                success: function () {
                    console.log('预览成功')
                },
                error: function (status, xmlDoc) {
                    if (403 === status) {
                        console.log('设备不支持Websocket取流')
                    } else {
                        console.log('预览失败')
                    }
                }
            });
        };
    
        if (oWndInfo != null) {// 已经在播放了，先停止
            WebVideoCtrl.I_Stop({
                success: function () {
                    startRealPlay();
                }
            });
        } else {
            startRealPlay();
        }
    }
    // 停止预览
    this.clickStopRealPlay = function() {
        var self = this
        var oWndInfo = WebVideoCtrl.I_GetWindowStatus(self.g_iWndIndex)
        if (oWndInfo != null) {
            WebVideoCtrl.I_Stop({
                success: function () {
                    console.log('停止预览成功')
                },
                error: function () {
                    console.log('停止预览失败')
                }
            });
        }
    }
}

（2）再建立一个vue界面，内容如下

<template>
  <el-main>
    <div><h1>进入页面</h1></div>
    <div class="video-play">
      <div id="divPlugin" class="divPlugin" style="width: 454px;height: 315px" />
    </div>
  </el-main>
</template>
<script>
  import { WebVideo } from '@/assets/script/webVideo.js'
  export default {
    name: 'VideoPlay',
    // mixins: [resize],
    data() {
      return {
        webVideo: '',
        hkvInfo: {
          ip: '10.196.43.200',
          username: 'admin',
          password: 'hik12345+'
        }
      }
    },
    created() {},
    mounted() {
      this.initVideoPlay()
    },
    beforeDestroy() {
      this.stopVideoPlay()
    },
    methods: {
      initVideoPlay() {
        this.webVideo = new WebVideo()
        this.$nextTick(() => {
          this.webVideo.init(this.hkvInfo.ip, this.hkvInfo.username, this.hkvInfo.password)
          this.webVideo.clickLogin()
        })
      },
      stopVideoPlay() {
        this.webVideo.clickStopRealPlay()
        this.webVideo.clickLogout()
      }
    }
  }
</script>

<style>
  .plugin {
    width: 500px;
    height: 300px;
  }
</style>

（3）引用海康开发包
将海康开发包，放到Public文件下

在index.html文件中引用相关js文件，如下图

  <script type="text/javaScript" src="./webVideoCtrl.js"></script>
  <script type="text/javaScript" src="./cryptico.min.js"></script>
  <script type="text/javaScript" src="./jquery-1.12.1.min.js"></script>

4 IIS正常发布网站

网站端口号为Nginx中配置的端口号9007

5 nginx环境部署

5.1 nginx配置

海康无插件开发包中地址打开nginx.conf文件
WEB无插件开发包_20211014_20211019120439\nginx-1.10.2\conf\nginx.conf

修改内容如下，
本地IP为10.196.43.220,127.0.0.1/localhost都可换成10.196.43.220
本地IIS配置IP端口号：127.0.0.1:9007
Nginx反向代理为localhost:9008

5.2 双击 start.bat 启动Nginx代理

6 前端访问

http://10.196.43.220:9007
访问地址一定要是本机的IP：10.196.43.220
127.0.0.1/localhost访问都是不会显示视频画面
