我使用netcore2.0并设置了log4net.LogicalThreadContext属性" requestid"我的中间件类中的每个请求都用于记录目的。
log4net.LogicalThreadContext.Properties["requestid"] = Guid.NewGuid().ToString("N");
但是" Microsoft.AspNetCore.Hosting.Internal.WebHost"记录行时,类不显示此属性。
我不知道如何为" Microsoft.AspNetCore.Hosting.Internal.WebHost"设置log4net.LogicalThreadContext.Propery [" requestid"]。
我希望将所有请求日志从头到尾绑定。 有没有人有任何可能有帮助的见解?
问候!
更新:这是代码
using Microsoft.Extensions.Logging;
...
public static ILoggerProvider Log4NetProvider;
public static void Main(string[] args)
{
#if DEBUG
Log4NetProvider = new Log4NetProvider("log4net.Debug.config", ((o,
exception) => exception.Message));
#else
Log4NetProvider = new Log4NetProvider("log4net.Release.config", ((o,
exception) => exception.Message));
#endif
var host = new WebHostBuilder()
.UseKestrel()
.UseContentRoot(Directory.GetCurrentDirectory())
.ConfigureLogging((hostingContext, logging) =>
{
logging.AddProvider(Log4NetProvider);
})
.ConfigureServices(services =>
{
services.AddAutofac();
})
.UseIISIntegration()
.UseStartup<Startup>()
.Build();
host.Run();
在Startup.cs中 配置(IApplicationBuilder应用程序,IHostingEnvironment环境)我已经设置为第一件事。
app.UseMiddleware<Log4NetRequestIdMiddleware>();
public class Log4NetRequestIdMiddleware
{
private readonly RequestDelegate _next;
public Log4NetRequestIdMiddleware(RequestDelegate next)
{
_next = next;
}
public async Task Invoke(HttpContext context)
{
log4net.LogicalThreadContext.Properties["requestid"] = Guid.NewGuid().ToString("N");
await _next(context);
}
}
Log4net配置文件&gt;
<?xml version="1.0" encoding="utf-8" ?>
<log4net>
<appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
<file value="C:\log\applog.log" />
<rollingStyle value="Size"/>

</layout>
</appender>
<root>
<level value="ALL" />
<appender-ref ref="RollingFile" />
</root>

Fileappender.log的另一个例子(标记为RequestId的粗体)

WebHost
记录器不显示属性 WebHost
记录器记录两条消息 - 请求启动消息和请求已完成消息。
请求启动消息没有看到requestid
属性,因为WebHost
运行并在第一个中间件包含到Startup
类中的管道中之前记录消息,其中requestid
属性已设置。
请求已完成消息未看到requestid
属性,因为(我猜)WebHost
记录器超出log4net.LogicalThreadContext
。就像Log4NetRequestIdMiddleware
logger在控制器操作中设置requestid
属性一样。
由于WebHost
logger会在Microsoft.AspNetCore.Hosting.Internal
命名空间的HostingApplicationDiagnostics
类深处记录消息,因此没有任何明确的扩展点可以注入设置requestid
属性的代码。
所以,我认为您可以在中间件中记录信息,就像WebHost
logger:
public async Task Invoke(HttpContext context)
{
var logger = httpContext.RequestServices.GetRequiredService<ILogger<Log4NetRequestIdMiddleware>>();
log4net.LogicalThreadContext.Properties["requestid"] = Guid.NewGuid().ToString("N");
var request = context.Request;
string logMsg = string.Format(
CultureInfo.InvariantCulture,
"Request starting {0} {1} {2}://{3}{4}{5}{6} {7} {8}",
request.Protocol,
request.Method,
request.Scheme,
request.Host.Value,
request.PathBase.Value,
request.Path.Value,
request.QueryString.Value,
request.ContentType,
request.ContentLength);
logger.LogDebug(logMsg);
await _next(context);
}

services.AddLogging(config =>
{
config.ClearProviders();
});
loggerFactory.AddLog4Net();
