Ihttpcontextaccessor，如何在控制器中创建该类的实例

private readonly IHttpContextAccessor _httpContextAccessor;

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

public void ConfigureServices(IServiceCollection services)
{
    // 其他服务的注册

    services.AddHttpContextAccessor();
}

public IActionResult YourAction()
{
    // 获取当前HTTP上下文
    var httpContext = _httpContextAccessor.HttpContext;

    // 获取当前用户的身份验证信息
    var user = httpContext.User;

    // 获取当前请求的路径
    var path = httpContext.Request.Path;

    // 其他操作

    return View();
}
