How to use middle war to get next request asp.net core 2 ?

How to get next request pipeline in case of token success .

suppose i need to get data from action result get request by post man

Code:

Code:

---

[HttpGet(Contracts.ApiRoutes.Security.GetUserMenus)] 
      public IActionResult GetUserMenu(string userId) 
      { 
          string strUserMenus = _SecurityService.GetUserMenus(userId); 
          return Ok(strUserMenus); 
      }

i write on postman link as then select get then write on header

key : authorization
value :eeerrttyyyyy

when invalid access token then it will show message invalid token

if valid access token it will continue execution and get result from action

this is actually i need on next but cannot do it .

Code:

Code:

---

public async Task InvokeAsync(HttpContext context, DataContext dataContext) 
        { 
             
                var validKey = false; 
 
             
                if (!validKey) 
                { 
                    context.Response.StatusCode = (int)HttpStatusCode.Forbidden; 
                    await context.Response.WriteAsync("Invalid Token"); 
                } 
                //if validm than next middleware Invoke 
                else 
            { 
                //success token
                context.Request.EnableRewind(); 
                await _next.Invoke(context); 
// how to get next request meaning i need to get result of action getusermenu 
               
                } 
             
             
        } 
    }
