how to access Header information in service stack service implementation / Methods - servicestack

Question

I am new to servicestack.net, and I am struggling to access the header information inside my methods. I am attaching the code I am using. It is in vb.net
Service stack Classes
a)Service Stack Request Class
Public Class LeaveManagementDashboardRequest
Public Property ClientID As String
Public Property DateFormatID As String
Public Property UserID As String
Public Property NOOFROWS As String
End Class
b)Service Stack Response Class
Public Class LeaveManagementDashboardResponse
Public Property data As String
End Class
c)Service Stack Service Class(Actual Service implementation)
Public Class LeaveManagementDashboardService
Implements IService(Of LeaveManagementDashboardRequest)
Private sqlCon As New SqlConnection
Public Function Execute(ByVal request As LeaveManagementDashboardRequest) As Object Implements ServiceStack.ServiceHost.IService(Of LeaveManagementDashboardRequest).Execute
Dim ds As New DataSet
If sqlcon.State = ConnectionState.Closed Then
Common.OpenConnection(sqlCon)
End If
Dim ClientID As String = request.ClientID
Dim UserID As String = request.UserID
Dim DataFormatID As String = request.DateFormatID
Dim NOOFROWS As String = request.NOOFROWS
Dim sqlcmd As New SqlCommand("abcdefg", sqlcon)
sqlcmd.CommandType = CommandType.StoredProcedure
sqlcmd.Parameters.Add(New SqlParameter("#UserID", SqlDbType.Int, 0))
sqlcmd.Parameters.Add(New SqlParameter("#DateFormatID", SqlDbType.TinyInt, 0))
sqlcmd.Parameters.Add(New SqlParameter("#Count", SqlDbType.SmallInt, 0))
sqlcmd.Parameters.Add(New SqlParameter("#ClientID", SqlDbType.Int, 0))
sqlcmd.Parameters(0).Value = UserID
sqlcmd.Parameters(1).Value = DataFormatID
sqlcmd.Parameters(2).Value = NOOFROWS
sqlcmd.Parameters(3).Value = ClientID
Dim dsResult As New DataSet
Dim sqlda As New SqlDataAdapter(sqlcmd)
sqlda.Fill(dsResult)
Dim obj As String = Common.GetJson(dsResult.Tables(0))
' obj.countries = lstCountries
sqlcon.Close()
sqlcon.Dispose()
Return New LeaveManagementDashboardResponse With {.data = obj}
Return dsResult
End Function
End Class
Routes are defined in the Global.aspx.cs file as given below
Public Class _Global
Inherits System.Web.HttpApplication
Public Class HelloAppHost
Inherits AppHostBase
Public Sub New()
MyBase.New("Plant Best Services", GetType(HelloAppHost).Assembly)
End Sub
Public Overrides Sub Configure(ByVal container As Container)
Routes.Add(Of LeaveManagementDashboardRequest)("/pml/Dashboard/LeavesRequests")
End Sub
End Class
Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
Dim apphost = New HelloAppHost()
apphost.Init()
End Sub

It's hard to decipher what question is being asked here, I'm going to assume you want to know how to access the header information in your services.
You should first look at using ServiceStack's New API for new services. When you inherit from Service you can access the HTTP Headers with:
public class MyService : Service
{
public LeaveManagementDashboardResponse Any(LeaveManagementDashboard request)
{
var httpHeader = base.Request.Headers["headerName"];
}
}
If you want to continue to use the Old API (e.g. IService<T>) then you want to implement the IRequiresRequestContext interface to get ServiceStack to inject the RequestContext into your service. Read the wiki docs for more info on this.
