如何使用httpcontextaccessor在.net核心中獲取控制器和動作名稱

Question

現在我正在將.Net MVC應用程序轉換為.Net Core應用程序

要記錄事件，我們在MVC中使用“ HttpContext”

LoggerException loggerException = new LoggerException();
loggerException.ApplicationName = "Service";
loggerException.Level = logLevel;
loggerException.Timestamp = DateTime.UtcNow.ToString();
loggerException.UserController = HttpContext.Current.Request.Url.Segments[2];
loggerException.Action = HttpContext.Current.Request.Url.Segments[3];
loggerException.IpAddress = HttpContext.Current.Request.UserHostAddress;

.Net核心中的“ IHttpContextAccessor”取代了“ HttpContext”。 我無法獲得用戶控制器和操作

我當前的.net核心代碼

LoggerException loggerException = new LoggerException();
loggerException.ApplicationName = appName;
loggerException.Level = logLevel;
loggerException.Timestamp = DateTime.UtcNow;
//loggerException.UserController = httpContextAccessor.HttpContext != null ? httpContextAccessor.HttpContext.User.ToString() : string.Empty;
//loggerException.Action = httpContextAccessor.HttpContext != null ? httpContextAccessor.HttpContext. : string.Empty;
loggerException.IpAddress = httpContextAccessor.HttpContext != null ? httpContextAccessor.HttpContext.Connection.RemoteIpAddress.ToString() : string.Empty;

在IActionContextAccessor.ActionContext屬性中獲取當前請求的RouteData ，然后獲取如下的控制器和動作名稱。

var rd = actionContextAccessor.ActionContext.RouteData;
string currentController = rd.Values["controller"].ToString();
string currentAction = rd.Values["action"].ToString();
