将用户名添加到Serilog [英] Add Username into Serilog

问题描述

我在 program.cs

public class Program
    {
        public static IConfiguration Configuration { get; } = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
            .AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"}.json", optional: true)
            .Build();

        public static void Main(string[] args)
        {
            Log.Logger = new LoggerConfiguration()
                .MinimumLevel.Override("Microsoft", LogEventLevel.Warning)
                .MinimumLevel.Override("System", LogEventLevel.Warning)
                .WriteTo.MSSqlServer(Configuration.GetConnectionString("DefaultConnection"), "dbo.Log")
                .Enrich.WithThreadId()
                .Enrich.WithProperty("Version", "1.0.0")
                .CreateLogger();
            try
            {
                BuildWebHost(args).Run();
            }
            catch (Exception ex)
            {
                Log.Fatal(ex, "Host terminated unexpectedly");
            }
            finally
            {
                Log.CloseAndFlush();
            }

        }

        public static IWebHost BuildWebHost(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseStartup<Startup>()
                .UseSerilog()
                .Build();
    }

现在我想在所有日志消息中添加HttpContext.Current.User.Identity.Name.

Now i want to add HttpContext.Current.User.Identity.Name into all log messages.

我尝试根据文档 https://github.com创建新的Enrich类/serilog/serilog/wiki/Configuration-Basics#enrichers

class UsernameEnricher : ILogEventEnricher
    {
        public void Enrich(LogEvent logEvent, ILogEventPropertyFactory propertyFactory, HttpContext httpContext)
        {
            logEvent.AddPropertyIfAbsent(propertyFactory.CreateProperty(
                    "Username", httpContext.User.Identity.Name));
        }
    }

但是与不知道 HttpContext 的 ILogEventEnricher 冲突.

我还尝试安装包含用户名Enricher的Nuget软件包 Serilog.Web.Classic ，但是目标框架.Net Framework和.Net Core之间存在冲突，因此我无法使用此插件.

I also tried to install Nuget package Serilog.Web.Classic which contains Username Enricher, but there is conflict between target framework .Net Framework and .Net Core therefore i cannot use this plugin.

有什么主意吗?

推荐答案

您可以创建一个中间件，将所需的属性放入LogContext.

You can create a middleware to put required property to LogContext.

public class LogUserNameMiddleware
{
    private readonly RequestDelegate next;

    public LogUserNameMiddleware(RequestDelegate next)
    {
        this.next = next;
    }

    public Task Invoke(HttpContext context)
    {
        LogContext.PushProperty("UserName", context.User.Identity.Name);

        return next(context);
    }
}

还需要在记录器配置中添加以下内容:

Also you need to add the following to your logger configuration:

.Enrich.FromLogContext()
