海康威视 iSecure Center 平台预览监控

1、需求：基于海康威视的ISC平台做二次开发，以视频预览为例进行简单阐述。

2、版本号：ISC V1.3.0

3、参考并感谢海康威视平台文档：/docs/5dc5969b3ad3fd808b9f7238bf1fa124

4、请仔细阅读海康提供的公开文档，通过平台的公开API进行访问，屏蔽复杂的逻辑和推流操作。

具体的代码如下所示：

package ga;import com.alibaba.fastjson.JSONArray;import com.alibaba.fastjson.JSONObject;import com.hikvision.artemis.sdk.ArtemisHttpUtil;import com.hikvision.artemis.sdk.config.ArtemisConfig;import java.util.*;public class GetCameraPreviewURL {static {ArtemisConfig.host = "ip，端口不用写";// 代理API网关nginx服务器ip端口ArtemisConfig.appKey = "秘钥appkey";// 秘钥appkeyArtemisConfig.appSecret = "秘钥appSecret";// 秘钥appSecret}private static final String ARTEMIS_PATH = "/artemis";public static String GetCameraPreviewURL(String cameraIndexCode) {/*** STEP3：设置接口的URI地址*/final String previewURLsApi = ARTEMIS_PATH + "/api/video/v1/cameras/previewURLs";Map<String, String> path = new HashMap<String, String>(2) {{put("https://", previewURLsApi);//根据现场环境部署确认是http还是https}};/*** STEP4：设置参数提交方式*/String contentType = "application/json";/*** STEP5：组装请求参数*/JSONObject jsonBody = new JSONObject();jsonBody.put("cameraIndexCode", cameraIndexCode);jsonBody.put("streamType", 0);jsonBody.put("protocol", "rtmp");jsonBody.put("transmode", 1);jsonBody.put("expand", "streamform=ps");String body = jsonBody.toJSONString();/*** STEP6：调用接口*/String result = ArtemisHttpUtil.doPostStringArtemis(path, body, null, null, contentType, null);// post请求application/json类型参数return result;}/*** 视频列表** @return*/private static String getCameraList() {final String previewURLsApi = ARTEMIS_PATH + "/api/resource/v1/cameras";Map<String, String> path = new HashMap<String, String>(2) {{put("https://", previewURLsApi);//根据现场环境部署确认是http还是https}};/*** STEP4：设置参数提交方式*/String contentType = "application/json";/*** STEP5：组装请求参数*/JSONObject jsonBody = new JSONObject();jsonBody.put("pageNo", 10);jsonBody.put("pageSize", 10);String body = jsonBody.toJSONString();/*** STEP6：调用接口*/String result = ArtemisHttpUtil.doPostStringArtemis(path, body, null, null, contentType, null);// post请求application/json类型参数return result;}/*** 视频在线列表** @return*/private static String getCameraListOnline(List<String> strArray) {/*** STEP3：设置接口的URI地址*/final String previewURLsApi = ARTEMIS_PATH + "/api/nms/v1/online/camera/get";Map<String, String> path = new HashMap<String, String>(2) {{put("https://", previewURLsApi);//根据现场环境部署确认是http还是https}};/*** STEP4：设置参数提交方式*/String contentType = "application/json";/*** STEP5：组装请求参数*/JSONObject jsonBody = new JSONObject();jsonBody.put("regionId", "root000000");jsonBody.put("includeSubNode", "1");jsonBody.put("indexCodes", strArray);jsonBody.put("status", 1);jsonBody.put("pageNo", 1);jsonBody.put("pageSize", 10);String body = jsonBody.toJSONString();/*** STEP6：调用接口*/String result = ArtemisHttpUtil.doPostStringArtemis(path, body, null, null, contentType, null);// post请求application/json类型参数return result;}/*** 获取根区域信息** @return*/private static String getRegionsRoot() {final String previewURLsApi = ARTEMIS_PATH + "/api/resource/v1/regions/root";Map<String, String> path = new HashMap<String, String>(2) {{put("https://", previewURLsApi);//根据现场环境部署确认是http还是https}};String contentType = "application/json";JSONObject jsonBody = new JSONObject();jsonBody.put("pageNo", 1);jsonBody.put("pageSize", 10);String body = jsonBody.toJSONString();/*** STEP6：调用接口*/String result = ArtemisHttpUtil.doPostStringArtemis(path, body, null, null, contentType, null);// post请求application/json类型参数return result;}/*** 获取根区域信息** @return*/private static String getSubRegions() {final String previewURLsApi = ARTEMIS_PATH + "/api/resource/v2/regions/subRegions";Map<String, String> path = new HashMap<String, String>(2) {{put("https://", previewURLsApi);//根据现场环境部署确认是http还是https}};String contentType = "application/json";JSONObject jsonBody = new JSONObject();jsonBody.put("parentIndexCode", "-1");jsonBody.put("resourceType", "camera");jsonBody.put("pageNo", 1);jsonBody.put("pageSize", 10);jsonBody.put("cascadeFlag", 0);String body = jsonBody.toJSONString();/*** STEP6：调用接口*/String result = ArtemisHttpUtil.doPostStringArtemis(path, body, null, null, contentType, null);// post请求application/json类型参数return result;}public static void main(String[] args) {String result = getCameraList();JSONObject object = JSONObject.parseObject(result);JSONObject data = (JSONObject) object.get("data");JSONArray dataList = (JSONArray) data.get("list");List<String> cameraCodeList = new ArrayList<>();// 获取视频列表for (Object obj : dataList) {// System.out.println(obj);cameraCodeList.add(((JSONObject) obj).getString("cameraIndexCode"));}// 判断是否在线JSONObject onlineObj = JSONObject.parseObject(getCameraListOnline(cameraCodeList));JSONObject jsonObject = (JSONObject) onlineObj.get("data");cameraCodeList.clear();for (Object onlineCamera : (JSONArray) jsonObject.get("list")) {// 区域编号String regionIndexCode = ((JSONObject) onlineCamera).getString("regionIndexCode");// 区域String regionName = ((JSONObject) onlineCamera).getString("regionName");// 摄像头编码String indexCode = ((JSONObject) onlineCamera).getString("indexCode");// 在线String online = "1".equals(((JSONObject) onlineCamera).getString("online")) ? "在线" : "不在线";// cnString cn = ((JSONObject) onlineCamera).getString("cn");System.out.println("区域编码：" + regionIndexCode + "\t区域名：" + regionName + "\t摄像头编码：" + indexCode + "\t在线：" + online + "\tcn：" + cn);if ("在线".equals(online)) {cameraCodeList.add(indexCode);}}for (String cameraCode : cameraCodeList) {String url = GetCameraPreviewURL(cameraCode);}}}

5、其中秘钥appkey和秘钥appSecret，联系管理员做如下准备：

开发前需要先获取对接的身份认证信息，AK/SK；平台会通过AK/SK认证方式来验证请求发送者的身份。

1.进入运管中心（http://ip:8001/center），进入【状态监控】模块，选择【API网关】，选择【API管理】功能，进入API管理中心。

2.选择【合作方管理】，平台安装后，默认会创建一个对内合作方，可以使用此合作方进行接口调用测试，实际运行环境需要根据实际的情况创建新的合作方。

3.点击合作方的名称，进入合作方详情界面，获取合作方key（AK）和合作方Secret（SK）。

6、程序跑通之后，我们会获取到视频的rtmp协议（我设置的协议是rtmp），日志如下所示：

com.hikvision.artemis.sdk.ArtemisHttpUtil - the Artemis Request is Success,statusCode:200 SuccessMsg:{"code":"0","msg":"success","data":{"url":"rtmp://192.168.20.130:1935/live/openUrl/7SIswj6"}}

7、使用rtmp://192.168.20.130:1935/live/openUrl/7SIswj6协议在vlc中能够正常播放；

8、我们嵌入到vue中或者使用如下代码进行测试，总是无法播放，这个问题困扰了我半个月，一直在找解决办法。直到5月26日得到海康威视二次开发群（150425667）的群友的支持，才得以解决，在此再次感谢这位群友。

rtmp://192.168.20.130:1935/live/openUrl/7SIswj6 后面 加上斜杠/ 即可正常播放
