能够在WCF中将主要对象从客户端传送到服务端

在WCF中,在客户端,用户将被认证,他的角色/权限将存储在客户端的Principal / Identity对象中。经过身份验证后,用户应该只能在某个角色中调用服务方法。为此,我需要将客户端Principal / Identity对象传输到服务端。但是一旦我到达服务端,主要对象是Windows Principal,Identity是Windows Identity。这不允许我检查是否应该根据客户端凭证调用服务方法。

是否可以将我的主体和身份对象从客户端传输到服务器端?我想将我的主要对象(Generic Principal)传输到服务器端。可能吗?请帮忙。

之前我发布了类似的问题如下:

Carry over client side customized Principal object to the WCF service side

我试图遵循答案,但我无法继承我的主要对象。

以下是详细信息。

客户端,我的Principal对象和标识对象在调试期间在立即窗口中显示如下:

System.Threading.Thread.CurrentPrincipal {} System.Security.Principal.GenericPrincipal     [System.Security.Principal.GenericPrincipal]:{System.Security.Principal.GenericPrincipal}     身份:{System.Security.Principal.GenericIdentity} System.Threading.Thread.CurrentPrincipal.Identity {} System.Security.Principal.GenericIdentity     [System.Security.Principal.GenericIdentity]:{System.Security.Principal.GenericIdentity}     AuthenticationType:“”     IsAuthenticated:false     姓名:“”

服务器端,我的主要对象和标识如下所示:

System.Threading.Thread.CurrentPrincipal {} System.Security.Principal.WindowsPrincipal     [System.Security.Principal.WindowsPrincipal]:{System.Security.Principal.WindowsPrincipal}     身份:{System.Security.Principal.WindowsIdentity} {} System.Security.Principal.WindowsIdentity     [System.Security.Principal.WindowsIdentity]:{System.Security.Principal.WindowsIdentity}     AuthenticationType:“NTLM”     IsAuthenticated:是的     名称:“MyDomain \ MyLoginID”

我的WCF客户端如下所示

客户代码:

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            ServiceReference1.Service1Client client = new Service1Client("NetTcpBinding_IService1");

            Console.WriteLine(client.GetData(6548));


            Console.ReadLine();
        }
    }
}

客户端配置如下所示:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <bindings>
            <netTcpBinding>
                <binding name="NetTcpBinding_IService1" closeTimeout="10:10:00"
                    openTimeout="10:10:00" receiveTimeout="10:10:00" sendTimeout="10:10:00"
                    transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions"
                    hostNameComparisonMode="StrongWildcard" listenBacklog="10"
                    maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10"
                    maxReceivedMessageSize="65536">
                    <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                        maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                    <reliableSession ordered="true" inactivityTimeout="10:10:00"
                        enabled="false" />
                    <security mode="Transport">
                        <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
                        <message clientCredentialType="Windows" />
                    </security>
                </binding>
            </netTcpBinding>
        </bindings>
        <client>
            <endpoint address="net.tcp://localhost:8888/Service1" binding="netTcpBinding"
                bindingConfiguration="NetTcpBinding_IService1" contract="ServiceReference1.IService1"
                name="NetTcpBinding_IService1">

            </endpoint>
        </client>
    </system.serviceModel>
</configuration>

服务代码如下所示:

[ServiceContract]
public interface IService1
{
    [OperationContract]
    string GetData(int value);

    [OperationContract]
    CompositeType GetDataUsingDataContract(CompositeType composite);

    // TODO: Add your service operations here
}

// Use a data contract as illustrated in the sample below to add composite types to service operations
[DataContract]
public class CompositeType
{
    bool boolValue = true;
    string stringValue = "Hello ";

    [DataMember]
    public bool BoolValue
    {
        get { return boolValue; }
        set { boolValue = value; }
    }

    [DataMember]
    public string StringValue
    {
        get { return stringValue; }
        set { stringValue = value; }
    }
}


public class Service1 : IService1
{
    public string GetData(int value)
    {
        return string.Format("You entered: {0}", value);
    }

    public CompositeType GetDataUsingDataContract(CompositeType composite)
    {
        if (composite == null)
        {
            throw new ArgumentNullException("composite");
        }
        if (composite.BoolValue)
        {
            composite.StringValue += "Suffix";
        }
        return composite;
    }
}
