我们很久以前就编写了一个代码来调用具有域凭据的服务。现在，域已更改，并计划使用默认的Windows帐户
所以我试图通过配置重置asmx web服务的网络凭据。
我创建了一个SoapExtentsion类，并尝试覆盖那里，即使它执行了该行。但是它永远不会被应用，并且下面的现有代码总是能胜出
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
计划通过其他dll和配置更改进行注入(inject)。因此，现在不需要/禁止在上面原始代码中进行代码更改
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;
}
}
}
}
}
<system.web>
<webServices>
<soapExtensionTypes>
<add type="MyAssembly.WindowsDefCredSoapExtn, MyAssembly" priority="1" group="Low"/>
</soapExtensionTypes>
</webServices>
</system.web>
谁知道如何通过config动态更改用于ASMX服务的网络凭据？
更新:
调试时，我可以看到网络凭据已重置。但是调用请求时，它将以某种方式发送到服务器。
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:
参见最后一行AcquireCredentialsHandle通过
authdata。即使重置了服务扩展名，也会使用在prxy.Credentials = new System.Net.NetworkCredential("MyAccount", "pwd", "MyDomain")中设置的凭据。System.Net Verbose: 0 : [11584] WebRequest::Create(http://employee-service/empService.asmx)

更新2
我只是做了一个代码更改以进行测试，以下是套接字通信中的区别
AcquireDefaultCredential(package = NTLM, intent = Outbound)
VS
AcquireCredentialsHandle(package = NTLM, intent = Outbound, authdata = MyDomain\MyAccount)
最佳答案
如果我对您的理解正确，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 key 。
<appSettings>
<add key="YourDomain" value="yourAccount"/>
<add key="UserName" value="yourAccount"/>
<add key="Password" value="yourAccount"/>
</appSettings>
之后，在您的代码中，
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);
关于c# - NetworkCredential UseDefaultCredentials不起作用，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/38357792/
