c# - 使用轴摄像机 P1344 c# 进行 Onvif 身份验证

Question

我完全无法使用 ONVIF 身份验证。我想我已经尝试了所有方法，或者至少尝试了几乎所有方法，但我在互联网上找不到足够的信息。我已经使用 svcutil 创建了 stub 客户端，我进行身份验证的代码是(其中之一，因为我已经尝试了很多事情):

 string uri = "http://140.0.22.39/onvif/services";

 EndpointAddress serviceAddressPrueba = new EndpointAddress(uri);
 HttpTransportBindingElement httpBinding = new HttpTransportBindingElement();
 httpBinding.AuthenticationScheme = AuthenticationSchemes.Digest;
 var messegeElement = new TextMessageEncodingBindingElement();
 messegeElement.MessageVersion = MessageVersion.CreateVersion(EnvelopeVersion.Soap12, AddressingVersion.None);
CustomBinding bindprueba = new CustomBinding(messegeElement, httpBinding);
DeviceClient clientprueba = new DeviceClient(bindprueba, serviceAddressPrueba);
string passwordDigestBase64;
//HERE I PUT THE CODE TO ENCRYPT THE PASSWORD.
PasswordDigestBehavior behavior1 = new PasswordDigestBehavior("root",passwordDigestBase64);
clientprueba.Endpoint.Behaviors.Add(behavior1);
string d1;
string d2;
string d3;
string d4;

clientprueba.GetDeviceInformation(out d1, out d2, out d3, out d4);

之后出现以下错误:

{"The remote server returned an unexpected response: (400) Bad Request."}

如果您能帮助我提供任何信息来解决此问题，我将非常非常感激。

试试这个方法:

ServicePointManager.Expect100Continue = false;
var endPointAddress = new EndpointAddress("http://" + cameraAddress + "/onvif/device_service");
var httpTransportBinding = new HttpTransportBindingElement { AuthenticationScheme = AuthenticationSchemes.Digest };
var textMessageEncodingBinding = new TextMessageEncodingBindingElement { MessageVersion = MessageVersion.CreateVersion(EnvelopeVersion.Soap12, AddressingVersion.None) };
var customBinding = new CustomBinding(textMessageEncodingBinding, httpTransportBinding);
var passwordDigestBehavior = new PasswordDigestBehavior(adminName, adminPassword);
var deviceClient = new DeviceClient(customBinding, endPointAddress);
deviceClient.Endpoint.Behaviors.Add(passwordDigestBehavior);

请注意，将 ServicePointManager.Expect100Continue 设置为 false 非常重要。
