How to configure services based on request in ASP.NET Core

Question

In ASP.NET Core we can register all dependencies during start up, which executed when application starts. Then registered dependencies will be injected in controller constructor

Answer 1

It is possible by using the HttpContextAccessor in Startup.cs

services.AddHttpContextAccessor();
services.AddScoped(provider =>
            {
                var contextAccessor = provider.GetService();
                var httpContext = contextAccessor.HttpContext;
                
                var contextVariable = httpContext. ...
                
                // Return implementation of IYourService that corresponds to your contextVariable

              
            });
