AS.NET Core自定义类中全局访问HttpContext

public class MvcContext
{
	public static IHttpContextAccessor Accessor;
	public static HttpContext GetContext()
	{
		return Accessor.HttpContext;
	}

}

public void ConfigureServices(IServiceCollection services)
{
	services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env, IHttpContextAccessor accessor)
{
	MvcContext.Accessor = accessor;
}

var httpcontext = MvcContext.GetContext();
