Question

我试图从onvif设备获取实时流我的程序搜索并成功找到摄像机IP和onvif端口，但在下一步获取设备信息我面临此错误：

没有端点侦听http://192.168.1.89/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。

我不知道我的代码有什么问题，即使我想从设备中获取时间和日期也有同样的错误！我的代码是：

  private Device deviceChannel = null;
    private System.ServiceModel.Channels.Binding binding = null;


    private string serverNetworkAddress;
    private string serviceAddress;
    private string serverUsername = "";
    private string serverPassword = "";

     InitializeComponent();

        serverUsername = OnvifUserTextBox.Text;
        serverPassword = OnvifPwdTextBox.Text;
        serverNetworkAddress = serverAddrTextBox.Text;
        serviceAddress = string.Format("http://{0}/onvif/device_service", serverNetworkAddress);

        //Create Binding
        binding = CreateBinding();
     private static System.ServiceModel.Channels.Binding CreateBinding()
    {


        HttpTransportBindingElement httpTransport = new HttpTransportBindingElement();

        TransportSecurityBindingElement transportSecurity = new TransportSecurityBindingElement();
        transportSecurity.EndpointSupportingTokenParameters.SignedEncrypted.Add(
            new UsernameTokenParameters());

        transportSecurity.AllowInsecureTransport = true;
        transportSecurity.IncludeTimestamp = false;

        TextMessageEncodingBindingElement me =
            new TextMessageEncodingBindingElement(MessageVersion.Soap12, Encoding.UTF8);

        return new CustomBinding(transportSecurity, me, httpTransport);
    }
   private static TChannel GetChannel<TChannel>       (System.ServiceModel.Channels.Binding binding,
        string serviceAddressText,
        string serverUsername,
        string serverPassword)
    {
        EndpointAddress serviceAddress = new EndpointAddress(serviceAddressText);
        ChannelFactory<TChannel> channelFactory =
            new ChannelFactory<TChannel>(binding, serviceAddress);

        // configure the username credentials on the channel factory 
        UsernameClientCredentials credentials =
            new UsernameClientCredentials(new UsernameInfo(serverUsername, serverPassword));

        // replace ClientCredentials with UsernameClientCredentials
        channelFactory.Endpoint.Behaviors.Remove(typeof(ClientCredentials));
        channelFactory.Endpoint.Behaviors.Add(credentials);

        return channelFactory.CreateChannel();
    }
 private void button2_Click(object sender, EventArgs e)
    {
      //getting the device information
        listBox.Items.Clear();
        serverUsername = OnvifUserTextBox.Text;
        serverPassword = OnvifPwdTextBox.Text;
        serverNetworkAddress = serverAddrTextBox.Text;
        serviceAddress = string.Format("http://{0}/onvif/device_service", serverNetworkAddress);

        // string model, firmwareVersion, serialNumber, hardwareId;

        try
        {
            // Create a client with given client endpoint configuration
            deviceChannel =

            GetChannel<Device>(binding, serviceAddress, serverUsername, serverPassword);

            // deviceChannel.GetDeviceInformation= (  out model, out FirmwareVersion, out SerialNumber, out HardwareId);
            //get date and time
            var timemamo = deviceChannel.GetSystemDateAndTime();
            listBox.Items.Add(timemamo);



          var info = deviceChannel.GetDeviceInformation(new GetDeviceInformationRequest());
          //MessageBox.Show(string.Format("Model: {0}", info.Model));

            string strManuf = string.Format("Manufacturer: {0}", info.Manufacturer);
            listBox.Items.Add(strManuf);

            string strModel = string.Format("Model: {0}", info.Model);
            listBox.Items.Add(strModel);
            string strFw = string.Format("Firmware Version: {0}", info.FirmwareVersion);
            listBox.Items.Add(strFw);

            string strSerialNo = string.Format("Serial Number: {0}", info.SerialNumber);
            listBox.Items.Add(strSerialNo);

            string strHwId = string.Format("Hardware Id: {0}", info.HardwareId);
            listBox.Items.Add(strHwId);



        }
        catch (Exception exception)
        {
            string str = string.Format("GetDeviceInformation():mamo " + exception.Message);
            listBox.Items.Add(str);

    }

Answer 1

您的Onvif设备可能无法侦听默认端口。尝试将正确的端口号（Onvif端口，而不是HTTP或RTSP）添加到URL，例如： http://192.168.1.89:8182/onvif/device_service

Answer 2

使用554端口，它是onvif

中实时流媒体的默认端口

Answer 3

尝试扫描IP摄像机上所有打开的端口。

例如，在UNIX系统中，您可以使用命令nmap -p- 192.168.1.89。

然后，尝试为所有找到的端口打开相同的路径。在我的相机端口中，端口8999远非标准，没有-p-标志就没有出现在快速扫描模式中。
