我第一次使用IPCams，我正在尝试连接到OnVif相机。我已经查看了各种论坛和堆栈溢出，我已经提出了以下代码。我知道代码没有做任何有用的事情，但它只是现在的概念证明。它找到了我网络上的所有4个摄像头，然后我手动连接到其中一个摄像头以撤回一些信息，例如 GetServices 。
我在这个阶段得到400个错误的响应错误。我已经使用WireShark查看了来回流量，看来一切正常，关于生成的密码，据我所知（安全和加密根本不是我的区域！）。
任何人都可以提供帮助或建议吗？

我在相机上启用了onvif（通过创建一个名为“test”的管理员用户，密码为“test”。相机密码是默认的“root”和“pass”，因为它是一个Axis相机。
答案 0 :(得分：1)
以这种方式配置与摄像机的连接：
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);
我知道这几乎就是你所做的，但让ServicePointManager.Expect100Continue错误很重要。

检查相机是否启用了重放攻击保护。如果是这样，请检查计算机时间与相机之间的时差。根据ONVIF的规格，允许的时差必须为+ - 5秒。否则你会收到错误。
如果是这种情况，您有几种选择：
1-禁用重播攻击保护功能。建议不要这样做，因为您需要在需要使用的所有相机中禁用此功能。
2-您可以将相机的时间与计算机时间同步。同样不建议用于第一个选项的相同问题。
3-如果您可以将WSE 3.0更改为其他选项。在WSE3.0中创建 UsernameToken 后，您无法更改已创建属性，该属性用于创建加密。 here
