WCF - Transport Authentication - Get Credentials of Authenticated User

问题

I have a NetTcpBinding with SecurityMode.TransportWithMessageCredential.

Transport.ClientCredentialType is set to MessageCredentialType.Windows, but I'm considering MessageCredentialType.UserName.

Then there's a class DataStoreServerProxy for fetching database data which implements IDataStoreContract.

It contains methods such as this one:

Private Function Common_IDataStoreContract_ModifyData(ByVal ParamArray dmlStatements As ModificationStatement()) As ModificationResult Implements IDataStoreContract.ModifyData
        Return wrappedDataStore.ModifyData(dmlStatements)
    End Function

In order to get to that DB point, user must have already supplied the credentials. The question is, how to obtain them in those methods? Depending on the user name, I have to decide whether to allow access to some tables or not.

回答1:

Username can be retrieved using OperationContext.Current.ServiceSecurityContext.PrimaryIdentity.Name
