我在WebApi项目中使用了logging.cs类来记录有关传入请求的信息。
该类是从Global.asax中的Application_BeginRequest()方法触发的。 我需要在请求中获取Controller名称和Authorization标头。怎么做 ?
我一直在使用HttpRequest Request对象,但是似乎无法充分利用我真正需要的东西。(尽管Http请求的方法似乎很简单!!)
对于Authorization标头,我认为它就像“ Request.Headers [” Authorization“];”一样简单。但是,当前返回为null。
我的代码在下面,任何方向或建议将不胜感激。-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);
}
}
}

您应该实现一个用于记录日志的操作过滤器,这样您就可以通过HttpActionContext参数访问控制器名称
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:
public class Logger : ActionFilterAttribute
{
public override void OnActionExecuting(HttpActionContext actionContext)
{
string controllerName =
actionContext.ControllerContext.ControllerDescriptor.ControllerName;
}
public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
{
}
}

您可以装饰每个需要记录的方法,[Logger]也可以在控制器级别进行处理,以记录发生在该控制器内部的每个调用。最后,可以使操作过滤器成为全局过滤器,以便每次在项目中调用任何操作时都可以运行该过滤器。
与Sin的答案类似,但针对 ASP.Net Core 3.1:
var myControllerName = ControllerContext.ActionDescriptor.ControllerName;
