我想在来自客户端/用户的每个 Web 请求上将客户端地址标头(客户端的 IP 地址)添加到 SOAP 标头。
我使用WCF服务,我的实现类如下:
public class Service : IService
{
public Guid UserId()
{
if (MemUser != null)
return (Guid)MemUser.ProviderUserKey;
else
return Guid.Empty;
}
public void SystemLog(Nullable<Guid> Customer, ResultCode Result, FacilityCode Facility, int Code, string Info)
{
// get IP address out of the SOAP header, if any
string clientAddress = string.Empty;
if ((ClientAddress != null) && !String.IsNullOrEmpty(ClientAddress.IPAddress))
clientAddress = ClientAddress.IPAddress;
else if ((HttpContext.Current != null) && (HttpContext.Current.Request != null) && !String.IsNullOrEmpty(HttpContext.Current.Request.UserHostAddress))
clientAddress = HttpContext.Current.Request.UserHostAddress;
SystemLog(Customer, Result, Facility, Code, Info, clientAddress); //writes into database
}
//other methods
}
我的界面如下所示:
[ServiceContract(Name = "ServiceSoap", Namespace = "http://www.example.com/webservice"), XmlSerializerFormat]
public interface IService
{
[OperationContract(Action = "http://www.example.com/webservice/UserId")]
Guid UserId();
//other implementations
}
如果我有一个由 SoapHeader 继承的 ClientAddressHeader 类,例如
public class ClientAddressHeader : SoapHeader
{
public string IPAddress;
public ClientAddressHeader(){}
}
我可以使用 [WebMethod] 在 wse 中轻松传递 SOAP 标头(ClientAddress),例如:
[WebService(Namespace = "http://www.example.com/webservice")]
public class Service : System.Web.Services.WebService
{
public ClientAddressHeader ClientAddress;
[WebMethod, SoapHeader("ClientAddress", Direction = SoapHeaderDirection.In)] //client request
public Guid UserId()
{
if (MemUser != null)
return (Guid)MemUser.ProviderUserKey;
else
return Guid.Empty;
}
}
那么有人知道我在使用 WCF 时如何传递 SoapHeader 吗?
如果有人清楚地向我解释如何实现这一点,我真的很感激。
PS:我还阅读了msdn和Agent Message Inspector中的一些博客,它们都对我没有真正的用处,或者我不太了解。
