Question

我的任务是控制Cisco ptz摄像机。但是，我什至无法获得令牌。我已成功连接到相机，但是执行GetProfiles（）时出现错误。通过ONVIF设备管理器，一切正常，我可以看到有关相机的令牌和其他信息

非常感谢您能提供的任何帮助。

您确定要指向device_service的正确条目吗？在某些情况下，ONVIF界面可能会在与运行Web界面的端口80不同的端口上运行。

在这种情况下，通常，摄像机通过列出设备服务的XAddr（端口的格式不同于80）来响应探测消息。

我建议您使用wireshark并嗅探ONVIF设备管理器和摄像机之间的流量，并检查ONVIF设备管理器用于发布请求的正确URI。

“ GetProfiles”不适用于我的ONVIF摄像机
