Website

In EmespmdHttpClient class add

public void SetUserIdentifier(string userIdentifier)

        {

            this.DefaultRequestHeaders.Add("EMESPMD-USER", userIdentifier);

        }

From action method send _loggedInUser.XomPersonnelId as a separate param(naming userIdentifier) to each service call.

In Gateway service add below line next to try{

       _emespmdHttpClient.SetUserIdentifier(userIdentifier);

Service

Create an extension(HttpRequestExtensions) method in EMESPMD.Api.MessageHandler folder.

public static class HttpRequestExtensions

    {

        public static string RequestedUserIdentifier(this HttpRequestMessage request)

        {

            if (request.Headers.Contains("EMESPMD-USER"))

                return request.Headers.GetValues("EMESPMD-USER").First();

            return string.Empty;

           

        }

    }

Create a Base controller

public class BaseController : ApiController

    {

        protected string CurrentUserIdentifier() {

            return Request.RequestedUserIdentifier();

        }

    }

Inherit the Controller from base controller

       public class AdminController : BaseController

Call the CurrentUserIdentifier() method and pass the data as separate param to service.

      string userIdentifier = CurrentUserIdentifier();

            _log.LogMessage(_controllerName + " ; Action-" + actionName);

            CustomResponse<XomPersonnel> customResponse = new CustomResponse<XomPersonnel>();

            try

            {

                return _adminService.GetPersonnelInformation(lanId, userIdentifier);

            }

In service method call the LogMessage method which is having 2 arguments.

       _log.LogMessage(user,  _serviceName + "Method-" + actionName);
