Serilog记录nothing

Question

大家好，我有Mcv Api Project，我尝试用Serilog登录，但是当我尝试调用我的api并在文件/控制台中记录一些文本时，它是空的，我不能理解出了什么问题

我的program.cs

        public static void Main(string[] args)
        {

            var seriliogConfiguration = new ConfigurationBuilder()
                .SetBasePath(Path.Combine(Directory.GetCurrentDirectory(), "Configs"))
                .AddJsonFile("settings.json")
                .Build();
            var logger = new LoggerConfiguration()
                .ReadFrom.Configuration(seriliogConfiguration)
                .CreateLogger();
            CreateHostBuilder(args).Build().Run();
        }

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

我的设置json

{
  "Serilog": {
    "Using": [],
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Warning",
        "System": "Warning"
      }
    },
    "Enrich": [ "FromLogContext", "WithMachineName", "WithProcessId", "WithThreadId" ],
    "WriteTo": [
      {
        "Name": "Console"
      },
      {
        "Name": "File",
        "Args": {
          "path": "D:\\Logs\\logs.txt",
          "outputTemplate": "{Timestamp:G} {Message}{NewLine:1}{Exception:1}"
        }
      }
    ]
  }
}

当我尝试在文件和控制台中执行日志记录时，

        private readonly ILogger<WeatherForecastController> _logger;
        public WeatherForecastController(ILogger<WeatherForecastController> logger) =>  _logger = logger;
       
        public IEnumerable<WeatherForecast> Get() =>_logger.LogInformation("You requested Get()");

因为Serilog没有注入到Asp.net Core容器中。控制器中调用的接口不是Serilog方法。因此，日志将不会写入文件。您需要修改Program.cs。

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

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
                var seriliogConfiguration = new ConfigurationBuilder()
                   .SetBasePath(Path.Combine(Directory.GetCurrentDirectory(), "Configs"))
                   .AddJsonFile("settings.json")
                   .Build();
                webBuilder.UseSerilog((hostingContext, loggerConfiguration) =>
                {
                    loggerConfiguration.ReadFrom.Configuration(seriliogConfiguration);

                });
            });
}

我在此操作中添加了一个日志。

    [HttpGet]
    public IActionResult Get()
    {
        _logger.LogInformation("This info is in index");

        return Ok();
    }

在控制台中。

在此日志文件中。
