EasyCVR接入华为视频云系统查询集群编码和查询网关

EasyCVR是TSINGSEE青犀视频平台中接入协议较为广泛的平台，在经过我们的测试之后，已经能够接入华为视频云系统。本文介绍一下EasyCVR接入华为视频云系统查询集群编码和查询网关的步骤。

1、查询集群编码。该接口适配支持集群功能的产品:

//cpp code
IVS_INT32 IVS_SDK_GetClusterList(
  IVS_INT32 iSessionID, 
  const IVS_CHAR* pDomainCode,
  IVS_CLUSTER_INFO_LIST* pClusterList);

  //cpp code
IVS_INT32 iRet = IVS_FAIL;
iRet = IVS_SDK_Init();
if (IVS_SUCCEED != iRet)
{
  return 0;
}
IVS_LOGIN_INFO LoginReqInfo = {0};
LoginReqInfo.stIP.uiIPType = IP_V4;
strncpy(LoginReqInfo.stIP.cIP, "192.168.1.1", IVS_IP_LEN);
LoginReqInfo.uiPort = 9900;
strncpy(LoginReqInfo.cUserName, "Admin", IVS_NAME_LEN);
strncpy(LoginReqInfo.pPWD, "super123", IVS_PWD_LEN);

iRet = IVS_SDK_Login(&LoginReqInfo, &iSessionID);

if (IVS_SUCCEED == iRet)
{  
  const IVS_CHAR* pDomainCode = "6a7d3ca5ec984fe48ac634e3b22ff36a";
  IVS_CLUSTER_INFO_LIST clusterInfoList;
  iRet = IVS_SDK_GetClusterList(iSessionID, pDomainCode, &clusterInfoList);

  if (IVS_SUCCEED == iRet) 
  { 
    //成功
  }
}

2、查询网关接口。该接口适配支持集群功能的产品:

//cpp code
IVS_INT32 IVS_SDK_GetClusterCgList(
  IVS_INT32 iSessionID, 
  const IVS_CHAR* pDomainCode, 
  const IVS_CHAR* pClusterCode, 
  IVS_CHAR** pClusterCgList);

iSessionID 代表登录成功后的会话ID
pDomainCode 域编码
pClusterCode 集群编码
pClusterList 查询网关响应XML，详见 如下表1查询网关响应XML

响应XML：

  //cpp code

IVS_INT32 iRet = IVS_FAIL;
iRet = IVS_SDK_Init();
if (IVS_SUCCEED != iRet)
{
  return 0;
}
IVS_LOGIN_INFO LoginReqInfo = {0};
LoginReqInfo.stIP.uiIPType = IP_V4;
strncpy(LoginReqInfo.stIP.cIP, "192.168.1.1", IVS_IP_LEN);
LoginReqInfo.uiPort = 9900;
strncpy(LoginReqInfo.cUserName, "Admin", IVS_NAME_LEN);
strncpy(LoginReqInfo.pPWD, "super123", IVS_PWD_LEN);

iRet = IVS_SDK_Login(&LoginReqInfo, &iSessionID);

if (IVS_SUCCEED == iRet)
{  
  const IVS_CHAR* pDomainCode = "6a7d3ca5ec984fe48ac634e3b22ff36a";
  const IVS_CHAR* pClusterCode = "2BCBC3DEA03211E78000643E8C33B73B";

  IVS_CHAR* pRspXml = NULL;
  iRet = IVS_SDK_GetClusterCgList(iSessionID, pDomainCode, pClusterCode, &pRspXml);
  if (NULL != pRspXml)
  {
    IVS_SDK_ReleaseBuffer(pRspXml);
    pRspXml = NULL;
  }
}
