NetworkCredential UseDefaultCredentials无法正常工作

我们编写了一个代码，用于调用具有域凭据的服务。 现在域已更改并计划使用默认Windows帐户

所以我试图通过配置重置asmx webservice的网络凭据。 我创建了一个SoapExtentsion类，并尝试覆盖它，即使它执行该行。 但它永远不会被应用，并且总是以下现有的代码获胜

实际代码

EmployeeService prxy = new EmployeeService(); prxy.Credentials = new System.Net.NetworkCredential("MyAccount", "pwd", "MyDomain"); //prxy.UseDefaultCredentials = true;// It works but we dont want code change prxy.GetEmployee(empId); 

新代码/配置仅更改

计划通过额外的dll和配置更改注入。 因此，现在不需要/禁止原始代码中的代码更改

 public class WindowsDefCredSoapExtn : SoapExtension { public override object GetInitializer(Type serviceType) { return ""; } public override object GetInitializer(LogicalMethodInfo methodInfo, SoapExtensionAttribute attribute) { return ""; } public override void Initialize(object initializer) { //throw new NotImplementedException(); } public override void ProcessMessage(SoapMessage message) { if (message is SoapClientMessage) { if (message.Stage == SoapMessageStage.BeforeSerialize) { ((SoapClientMessage)message).Client.Credentials=null; (((SoapClientMessage)message)).Client.UseDefaultCredentials = true; } } } } }        

任何人都知道如何通过配置动态更改用于ASMX服务的网络凭据？

更新：

在调试时，我可以看到网络凭据被重置。 但不知何故，它在调用请求时会发送到服务器。

 EmployeeService prxy = new EmployeeService(); prxy.Credentials = new System.Net.NetworkCredential("MyAccount", "pwd", "MyDomain"); //while debug, prxy.UseDefaultCredentials= false here //My soap extension gets executed and resets credentials. prxy.GetEmployee(empId); //while debug, prxy.UseDefaultCredentials= true here //while debug prxy.Credentials are null here. 

输出窗口：

查看最后一行AcquireCredentialsHandle传递authdata 。 即使我的服务扩展重置，也会使用prxy.Credentials = new System.Net.NetworkCredential("MyAccount", "pwd", "MyDomain")中设置的凭据。

更新2

我刚刚为测试做了代码更改，下面是套接字通信的差异

 AcquireDefaultCredential(package = NTLM, intent = Outbound) 

VS

 AcquireCredentialsHandle(package = NTLM, intent = Outbound, authdata = MyDomain\MyAccount)

如果我理解正确，那么我认为您需要在配置文件中的appSettings下为您的帐户，用户名和密码添加密钥。

在你的代码中，

 EmployeeService prxy = new EmployeeService(); prxy.Credentials = new System.Net.NetworkCredential(System.Configuration.ConfigurationManager.AppSettings["UserName"].ToString(), System.Configuration.ConfigurationManager.AppSettings["Password"].ToString(), System.Configuration.ConfigurationManager.AppSettings["YourDomain"].ToString()); //while debug, prxy.UseDefaultCredentials= false here //My soap extension gets executed and resets credentials. prxy.GetEmployee(empId);
