如何从服务层获取 HttpContext

Question

I have requirement to add in a header on each request to a service a header MyHeader. MyHeader is the jwt I have received when the user is logging on.

I tried to read it from HttpContext.Request.Headers. I am trying to access it in my service. I could get the result in the controller but not on the Service layer. Can anyone help me to get the same on service class.

I'm using Asp.net core

In Startup#ConfigureServices:

services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();

In your service class:

public class YourServiceClass
{
    private readonly IHttpContextAccessor _httpContextAccessor;
    ...

    // constructor
    public YourServiceClass(IHttpContextAccessor httpContextAccessor, ...)
    {
      _httpContextAccessor = httpContextAccessor;
      ...
    }

    public void YourServiceMethod() 
    {
      var headers = _httpContextAccessor.HttpContext.Request.Headers;
      ...
    }

    ...
