ASP.NET Core 中 Serilog 文件名中的用户名

Question

我有一个 ASP.NET Core Web API。我需要将用户名添加到 Serilog 文件名中。我的

appsettings.json

文件如下所示：

"Serilog": {
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Warning",
        "Microsoft.Hosting.Lifetime": "Information"
      }
    },
    "WriteTo": [
      {       
        "Name": "File",
        "Args": {       
          "Path": "E:\\WebSite\\Development\\HealthAPI\\Logs\\log.txt",
          "rollingInterval": "Hour",
          "outputTemplate": "[{Timestamp:yyyy-MM-dd HH:mm:ss} {CorrelationId} {Level:u3}] [{Username}] {Message:lj}{NewLine}{Exception}"
        }
      }
    ]
  }

这是

program.cs

:

var _logger = new LoggerConfiguration()
     .ReadFrom.Configuration(builder.Configuration)
     .MinimumLevel.Override("Microsoft.AspNetCore", LogEventLevel.Warning)
     .Enrich.FromLogContext()
     .CreateLogger();
builder.Logging.AddSerilog(_logger);

app.UseMiddleware<LogUserNameMiddleware>();
app.UseSerilogRequestLogging();

我的中间件是

public class LogUserNameMiddleware
{
    private readonly RequestDelegate next;

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

    public async Task Invoke(HttpContext context)
    {
        using (LogContext.PushProperty("UserName", context.User.Identity.Name ?? "anonymous"))
        {
            await next(context);
        }
    }
}

我需要在文件名中包含用户名，例如

Log_ABC_Date.txt

。

更新1： 我更改了 Program.cs :

  var _logger = new LoggerConfiguration()
 .WriteTo.Map("LoginController", "Other", (name, wt) => wt.File(@"E:\Logs\log-{name}.txt"))
 .MinimumLevel.Override("Microsoft.AspNetCore", LogEventLevel.Warning)
 .Enrich.FromLogContext()
 .CreateLogger();

还有我的控制器：

 private readonly Serilog.ILogger _logger = Log.Logger.ForContext("LoginController","Username");

 _logger.Warning("Helllo !! {Name}",user.UserName);

这仍然是一个问题。由于 Serilog.Sinks.Map 是围绕映射函数构建的，因此无法使用 JSON 配置，因此我使用 Program.cs 来配置 Serilog。

根据Nicholas Blumhardt的建议，我实现了，请查看下面。

1。项目结构

2。 LogUserNameMiddleware.cs

using Serilog.Context;

namespace LogUserName1
{
    public class LogUserNameMiddleware
    {
        private readonly RequestDelegate _next;
        private readonly ILogger<LogUserNameMiddleware> _logger;

        public LogUserNameMiddleware(RequestDelegate next, ILogger<LogUserNameMiddleware> logger)
        {
            _next = next;
            _logger = logger;
        }

        public async Task Invoke(HttpContext context)
        {
            var userName = context.User.Identity.Name ?? "anonymous";
            using (LogContext.PushProperty("UserName", userName))
            {
                await _next(context);
            }
        }
    }

}

3.程序.cs

using Microsoft.AspNetCore.Authentication.Negotiate;
using Serilog.Events;
using Serilog;

var builder = WebApplication.CreateBuilder(args);

var _logger = new LoggerConfiguration()
    .MinimumLevel.Override("Microsoft.AspNetCore", LogEventLevel.Information)
    .Enrich.FromLogContext()
    .WriteTo.Map(
        keyPropertyName: "UserName",
        defaultKey: "anonymous",
        (userName, logConfiguration) => logConfiguration.File($"E:\\WebSite\\Development\\HealthAPI\\Logs\\log_{userName}_Date.txt")
    )
    .CreateLogger();

builder.Logging.AddSerilog(_logger);

// Add services to the container.
builder.Services.AddControllersWithViews();
...
