如何在WebApi请求中获取控制器名称
本文关键字:获取 控制器 请求 WebApi | 更新日期: 2023-09-27 18:01:24
我有一个logging.cs类,在我的WebApi项目中用于记录有关传入请求的信息。
类是由我的Application_BeginRequest()方法在我的Global.asax触发的。我需要在请求中获得控制器名称和授权头。
我一直在玩HttpRequest请求对象,但我似乎无法驾驭它到底是我需要什么。(虽然Http请求的方法看起来很简单!!)
对于授权头,我认为它将像"Request.Headers["Authorization"];"一样简单,但是目前它返回为空。
我的代码如下,任何指导或建议将不胜感激。杰森
namespace WCAPI.BLL
{
public class logging_2
{
private static HttpRequest Request
{
get { return HttpContext.Current.Request; }
}
private static HttpResponse Response
{
get { return HttpContext.Current.Response; }
}
public static void LogWcapiRequest(BLL.DebugTmr tmr)
{
if (tmr.EventType == DebugTmr.EventTypes.Null) { return; }
try
{
Services.AFSILog log = new Services.AFSILog();
log.Level = Services.LogLevels.Info;
log.SourceSystem = ANACore.AMTConfig.GetConfigurationValue("ConsoleLogSourceSystem");
if (Request.Url.IsLoopback) { log.SourceSystem += "_" + System.Environment.MachineName; }
log.Stamp = DateTime.Now;
log.Message = tmr.FormatedMsg;
log.Category = tmr.EventType.ToString();
List<Services.LogData> dets = new List<Services.LogData>();
dets.Add(new Services.LogData { DataType = Services.ParameterDataTypes.Int, DataKey = "Duration", DataValue = tmr.ElapsedMs.ToString() });
//This appears to be easy!!
var meth = Request.HttpMethod;
dets.Add(new Services.LogData { DataType = Services.ParameterDataTypes.Int, DataKey = "Method", DataValue = meth });
//Now how do I get Authorization Header and Controller name ?
foreach (BLL.DebugTmr.Waypoint wp in tmr.Waypoints)
{
dets.Add(new Services.LogData
{
DataType = Services.ParameterDataTypes.Int,
DataKey = wp.Name + "Ms",
DataValue = wp.ElapsedMs.ToString()
});
}
log.Parameters = dets.ToArray();
// This is what actually writes to the log I just need add Authorization header and Controller name to my log object
SaveLog(log);
}
catch (Exception ex)
{
Debug.Print("Page log create failed : {0}", ex.Message);
}
}
}
}
您应该为日志记录实现一个动作过滤器。这样,您就可以通过HttpActionContext
参数
Api控制器:
public class LeadsController : ApiController
{
[Logger]
public List<string> Get()
{
return new List<string> { "Lead 1", "Lead 2", "Lead 3", "Lead 4","Lead 5" };
}
}
过滤器:public class Logger : ActionFilterAttribute
{
public override void OnActionExecuting(HttpActionContext actionContext)
{
string controllerName =
actionContext.ControllerContext.ControllerDescriptor.ControllerName;
}
public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
{
}
}
你可以用[Logger]
装饰每个需要记录的方法,或者在控制器级别记录发生在该控制器内部的每个调用。最后,你可以将你的动作过滤器设置为全局的,这样每当在你的项目中调用任何动作时,它都会运行。
类似于Sin的回答,但针对ASP。Net Core 3.1:
var myControllerName = ControllerContext.ActionDescriptor.ControllerName;
如果您需要在controller操作中获取控制器名称,则可以使用
this.ActionContext.ActionDescriptor.ControllerDescriptor.ControllerName
