Serilog不会在.NET Core 2.1中登录到控制台

我创建了一个新的ASP.NET Core 2.1 Web应用程序并添加了这些Nuget包：

Serilog.AspNetCore 2.1.1
Serilog.Settings.Configuration 2.6.1
Serilog.Sinks.Console 3.1.1

Program.cs 看起来像这样：

public class Program
{
    public static void Main(string[] args)
    {
        CreateWebHostBuilder(args).Build().Run();
    }

    public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
            .UseStartup<Startup>()
            .UseSerilog((hostingContext, loggerConfiguration) => loggerConfiguration
                .ReadFrom.Configuration(hostingContext.Configuration)
                .Enrich.FromLogContext()
                .WriteTo.Console());
}

这是 appsettings.json 文件：

{
  "Serilog": {
    "Using": [ "Serilog.Sinks.Console" ],
    "MinimumLevel": "Debug",
    "WriteTo": [
      { "Name": "Console" }
    ],
    "Enrich": [ "FromLogContext" ],
    "Properties": {
      "Application": "MyApplication"
    }
  }
}

我添加了一个看起来像这样的控制器：

public class HelloController : Controller
{
    // GET
    public IActionResult Index()
    {
        Log.Debug("Test");
        return new OkObjectResult("Hello world");
    }
}

虽然 HelloController 本身按预期工作，但我没有看到控制台的 Test Debug输出 .

这是调用Controller后的控制台日志输出：

[21:39:16 DBG] Connection id "0HLEJO3CE6S7J" started.

    找到了：

    这不是我的控制器返回"Hello world"但是 Startup.cs 中的这一行：

    app.Run(async (context) => { await context.Response.WriteAsync("Hello World!"); });

    我建议做一些改进：

    • 不要复制接收器配置，不需要在代码和appsettings中配置相同的接收器 . 选择一个并继续使用它 .

    • ASP .NET Core旨在支持依赖注入 . 在 HelloController 中注入 ILogger<HelloController> 而不是访问静态 Log.Debug .

    • 赞赏你找到问题并在你的问题中报告它，它肯定会帮助其他开发人员 .

    对于Serilog和ASP .NET Core 2.1的一个非常小的例子，请看一下这个repo .
