log4net.LogicalThreadContext.Properties["requestid"]与Microsoft.AspNetCore.Hosting.Internal.WebHost
我使用netcore2.0，并将中间件类中的每个请求设置为log4net.LogicalThreadContext属性"requestid“，以便进行日志记录。
log4net.LogicalThreadContext.Properties["requestid"] = Guid.NewGuid().ToString("N");但是，"Microsoft.AspNetCore.Hosting.Internal.WebHost“类在记录行时不显示此属性。
我不知道如何将log4net.LogicalThreadContext.Propery"requestid“设置为"Microsoft.AspNetCore.Hosting.Internal.WebHost".
我希望把所有的请求日志从开始到结束。有人有什么有帮助的洞察力吗？
致以问候！
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配置(IApplicationBuilder应用程序，IHostingEnvironment env)中，我将其设置为第一件事。
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);
}

为什么WebHost记录器不显示该属性
WebHost记录器记录两条消息--请求启动消息和请求完成消息。
请求启动消息没有看到requestid属性，因为WebHost在Startup类中设置requestid属性的管道中包含的第一个中间件之前运行和记录消息。
请求完成的消息没有看到requestid属性，因为(我猜) WebHost记录器没有log4net.LogicalThreadContext。这就像Log4NetRequestIdMiddleware记录器如果在控制器操作中设置它，就不会看到requestid属性。
可能解决办法
由于WebHost记录器在HostingApplicationDiagnostics类中的某个地方从Microsoft.AspNetCore.Hosting.Internal命名空间记录消息，因此没有任何明确的扩展点来注入将设置requestid属性的代码。因此，我认为您可以像WebHost记录器那样在中间件中记录信息：
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);

创建您自己的LogProvider，像这样清除日志提供程序。
services.AddLogging(config =>
{
config.ClearProviders();
});
loggerFactory.AddLog4Net();本文介绍如何创建log4net日志。https://dotnetthoughts.net/how-to-use-log4net-with-aspnetcore-for-logging/
