Question

我正在制作一个c＃windows应用程序，它使用开源库Onvif收集连接到我网络的设备。

我正在这样做。

    ServicePointManager.Expect100Continue = false;
    var endPointAddress = new EndpointAddress("http://ip_address:port/onvif/device_service");
    var httpBinding = new HttpTransportBindingElement();            
    var bind = new CustomBinding(httpBinding);
    var temp = new DeviceClient(bind, endPointAddress);
    var request = new GetDeviceInformationRequest();
    var response = temp.GetDeviceInformation(request); ////// Error Here described bellow
    string firm = response.FirmwareVersion;
    string manu = response.Manufacturer;
    string serial = response.SerialNumber;
    string model = response.Model;

错误消息::没有端点侦听http：// something：port / onvif / device_service可以接受该消息。这通常是由不正确的地址或SOAP操作引起的

任何人都可以帮助我吗？

我认为我没有与服务器建立正确的连接，是这样吗？如果是，那么如何解决呢？

Answer 1

也许WS-DISCOVERY会为您提供额外的信息。我会尽量不要在相机的IP之后使用任何端口。

当测试将UDP发送到多播地址239.255.255.250，端口3702（WS-Discovery）时，这是摄像机的答案：

尝试发现响应并查看是否有任何XAddrs不是您期望的默认值。
