如何在 Web 中显示文件中的所有日志 api
How to show all logs in a file in web api
我创建了一个 API。通过 Web API Tracing using Log4net 我创建了一个日志文件。但是在这个文件中，只显示了一些成功的日志。但我想用 line number 显示所有可能的事件，即我日志中的所有 stack trace。以下是我所做的
创建了一个 API 示踪剂 Class
namespace ActualWebService
{
public class MyAPITracer : ITraceWriter
{
private static readonly ILog log = LogManager.GetLogger(typeof(MyAPITracer));
public void Trace(HttpRequestMessage request, string category, TraceLevel level, Action<TraceRecord> traceAction)
{
TraceRecord rec = new TraceRecord(request,category,level);
traceAction(rec);
WriteLog(rec);
}
private void WriteLog(TraceRecord rec)
{
string strLog = string.Format("{0};{1};{3}", rec.Category,rec.Operator,rec.Operation,rec.Message);
log.Info(strLog);
}
}
}
Web.config
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net" />
// other.....
</configSections>
<log4net>
<root>
<appender-ref ref="RollingFileAppender" />
</root>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">

<datePattern value="yyyyMMdd" />
<CountDirection value="1" />
<staticLogFileName value="true" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="5MB" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%date [%thread] %-5level %logger - %meesage%newline" />
</layout>
</appender>
<logger name="ApiLog">
<level value="ALL" />
</logger>
</log4net>
</configuration>
WebApiConfig.cs
log4net.Config.XmlConfigurator.Configure();
config.Services.Replace(typeof(System.Web.Http.Tracing.ITraceWriter), new MyAPITracer());
下面是我的日志文件内容

我创建了一个 exception/error 但它没有显示在我的日志文件中。如何使用行号显示其中的所有堆栈跟踪？
非常感谢任何帮助。
您需要更改 WriteLog 方法。
在此方法中使用了 class TraceRecord，您可以从 class.
中记录错误
回顾一下我对这个方法的实现：
private void WriteLog(TraceRecord rec)
{
if (rec.Exception == null)
{
string infoLog = string.Format("{0};{1};{3}", rec.Category, rec.Operator, rec.Operation, rec.Message);
log.Info(infoLog);
}
else
{
string errorLog = string.Format("{0};{1};{3}", rec.Category, rec.Operator, rec.Operation, rec.Message);
log.Error(errorLog, rec.Exception);
}
}
之后可以看到错误日志：

正如@Alexander I. 所说，您必须使用不同的日志方法，如 Info()、Warn()、Error() 等。
这里有进一步的link，其中包含一些关于 log4Net 的有用信息：
https://stackify.com/log4net-guide-dotnet-logging/
对于 asp.net web api 中的执行 handling/tracing，您还可以使用 ExceptionFilter (https://docs.microsoft.com/de-de/aspnet/web-api/overview/error-handling/web-api-global-error-handling)。
异常堆栈中的行号来自 PDB 文件。查看您发布的构建配置。 [ 项目属性 | Build ] -> Advanced 按钮 -> Debugging information 下拉
完整版或仅 PDB 就足够了。
如果您想要每个日志消息的堆栈跟踪，您可以在您的模式布局中使用%stacktrace甚至%stacktracedetail：
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%date [%thread] %-5level %logger - %message%newline%stacktrace%newline" />
</layout>
