getTalkUrl static method

Future getTalkUrl({ required String cameraIndexCode, int transmode = 1, int version = 2, bool isHttps = false, })

语音对讲,一般直接使用预览url即可,无需单独请求 'cameraIndexCode' 监控点唯一标识

version 1表示isc1.3版本及以前,2表示isc1.4版本及以后

transmode 协议类型( 0-udp，1-tcp),默认为tcp，

isHttps 是否使用https请求,需要根据实际情况选择参数,

isHttps是否为https请求

}) async {

    return;
  }

  ///根据版本切换地址,isc1.4之后用v2版本
  var talkURLs = talkURLsV2;
  if (version == 1) {
    talkURLs = talkURLsV1;
  }
  var headers = ArtemisConfig.createHeaders(talkURLs);

  ///根据实际服务器情况选用http或https
  String url = 'http://${ArtemisConfig.host}$talkURLs';
  if (isHttps) {
    url = 'https://${ArtemisConfig.host}$talkURLs';
  }
