ASP.NET核心返回HTTP响应并继续使用相同上下文的后台Worker

using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using System.Threading.Tasks;

public class MyController : ControllerBase
{
    private readonly IHttpContextAccessor _httpContextAccessor;

    public MyController(IHttpContextAccessor httpContextAccessor)
    {
        _httpContextAccessor = httpContextAccessor;
    }

    public IActionResult MyAction()
    {
        // 创建后台Worker执行耗时操作
        Task.Run(async () =>
        {
            // 获取当前HTTP上下文
            var httpContext = _httpContextAccessor.HttpContext;

            // 设置HTTP响应内容
            httpContext.Response.ContentType = "text/plain";
            await httpContext.Response.WriteAsync("Hello, World!");

            // 其他耗时操作...

            // 设置HTTP响应状态码
            httpContext.Response.StatusCode = StatusCodes.Status200OK;
        });

        // 返回HTTP响应
        return Content("Processing...");
    }
}
