定义DeviceClient(Bind，endPointAddress) [英] Defining DeviceClient(Bind, endPointAddress)

问题描述

我正在尝试与 ONVIF 认证的设备进行交互，例如能够访问简单的设备信息.

I am trying to interface with ONVIF certified equipment, like being able to access simple device information.

我一直在尝试使用由另一位成员在此处提供的以下代码:

I have been trying to use the following code, provided by another member here:

使用Visual Studios的.NET 4.0中的ONVIF身份验证2010

但是，在了解 DeviceClient 是什么以及它的功能时遇到了麻烦. 我试图在 ONVIF WSDLs 上作为一个类来找到它，但是没有用. C#， WSDL 和 ONVIF 非常新，因此感谢您的帮助.

However, am having trouble understanding what the function DeviceClient is and what it does. I have tried to find it on the ONVIF WSDLs and as a class, but with no avail. Am very new to C#, WSDLs and ONVIF, and as such appreciate any help.

提前谢谢！

推荐答案

当我的代码无法识别DeviceClient和MediaClient类时，我也遇到了类似的问题.从Hugo的评论中，我得到了线索，并从我已经作为Web参考添加的C#项目中删除了OnVif参考.然后只需添加以下参考作为服务参考即可，它对我有用:

I was stuck with similar issue when my code was unable to recognize DeviceClient and MediaClient classes. From Hugo's comments I got the clue and removed OnVif references from my C# project which I'd already added as Web References. Then simply added following references as Service References and it worked for me:

1. http://www.onvif.org/onvif/ver10/device/wsdl/devicemgmt.wsdl
2. http://www.onvif.org/onvif/ver10/media/wsdl/media.wsdl

1. http://www.onvif.org/onvif/ver10/device/wsdl/devicemgmt.wsdl
2. http://www.onvif.org/onvif/ver10/media/wsdl/media.wsdl

下面是我从StackOverflow上的另一篇文章中摘录的工作代码段.

Below is the working code snippet I took from another post on StackOverflow.

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);

这篇关于定义DeviceClient(Bind，endPointAddress)的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
