.net - 如何在不使用.Net Core 3 ASP.NET MVC中的第三方记录器的情况下登录文件？

Question

如何在 .NET CORE 3 ASP.NET MVC 中不使用第三方记录器(serilog，elmah等)登录到文件？我在https://docs.microsoft.com/ru-ru/aspnet/core/fundamentals/上找不到此信息。

Answer 1

If ASP.NET Core 3 MVC doesn't have such built-in functionality the code of using third-party logging providers will be acceptable for me.

MS正式建议使用第三方文件记录器。

在asp.net core 3.0中使用Serilog也非常方便:

1.program.cs

public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .UseSerilog((ctx, config) => { config.ReadFrom.Configuration(ctx.Configuration); })
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
            });

2. appsettings.json

"Serilog": {
"Using": [ "Serilog.Sinks.Console", "Serilog.Sinks.File" ],

"WriteTo": [
  { "Name": "Console" },
  { "Name": "Debug" },
  {
    "Name": "File",
    "Args": {
      "path": "log-{Date}.txt",
      "rollingInterval": "Day",
      "shared": true
    }
  }
],
"Properties": {
  "Application": "SampleApp"
}
}

3.使用以下NuGet软件包

<ItemGroup>    
    <PackageReference Include="Serilog.AspNetCore" Version="3.0.0" />
    <PackageReference Include="Serilog.Settings.Configuration" Version="3.1.1-dev-00209" />
    <PackageReference Include="Serilog.Sinks.File" Version="4.1.0" />  
</ItemGroup>

4.在 Controller 中:

public class HomeController : Controller
{
    private readonly ILogger<HomeController> _logger;

    public HomeController(ILogger<HomeController> logger)
    {
        _logger = logger;
    }

    public async Task Index()
    {
        _logger.LogInformation("Hello, World!");
    }
}

然后，您可以检查项目中现有的txt文件。
