如何配置从 appsettings.json 读取异步 Serilog

Question

我的 ASPCoreNet 项目中有以下内容：

appsetting.json：

{
  "Serilog": {
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft.AspNetCore": "Warning",
        "Microsoft.Hosting.Lifetime": "Information",
        "Microsoft": "Warning"
      }
    },
    "WriteTo": [
      {
        "Name": "Async",
        "Args": {
          "configure": [
            {
              "Name": "File",
              "Args": {
                "path": "logs/log-.txt",
                "rollingInterval": "Day",
                "outputTemplate": "[{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} {Level:u3}] {Message:lj} <s:{SourceContext}>{NewLine}{Properties:j}{NewLine}{Exception}"
              }
            }
          ]
        }
      },
      {
        "Name": "Console",
        "Args": {
          "outputTemplate": "[{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} {Level:u3}] {Message:lj} <s:{SourceContext}>{NewLine}{Properties:j}{NewLine}{Exception}",
          "theme": "Serilog.Sinks.SystemConsole.Themes.AnsiConsoleTheme::Code, Serilog.Sinks.Console"
        }
      }
    ],
    "Enrich": [ "WithMachineName", "WithThreadId", "FromLogContext" ]
  },
  "AllowedHosts": "*"
}

但是，当我从配置中读取时，我的记录器无法工作：

public class MyLogger
{
   public static ILogger LoggingInstance
   {
      var builder = new ConfigurationBuilder()
            .SetBasePath(env.ContentRootPath)
            .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
            .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
            .AddEnvironmentVariables();
        Configuration = builder.Build();
      
      Log.Logger = new LoggerConfiguration()
           .ReadFrom.Configuration(Configuration)
           .CreateLogger();
   }
}

但是，这似乎有效：

Log.Logger = new LoggerConfiguration()                 
        .WriteTo.Async(a => a.File(
                    outputTemplate: ""[{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} {Level:u3}] {Message:lj} <s:{SourceContext}>{NewLine}{Properties:j}{NewLine}{Exception}",
                    path: "logs/log-.txt",
                    rollingInterval: RollingInterval.Day
             )).CreateLogger();

当我尝试从配置创建异步记录器时，它什么也不做。当我对它做同样的事情时，效果很好。

我实际上必须将异步包装到文件中，但做得不正确：

{

“Serilog”：{ “使用”：[ “塞里洛格”， “Serilog.Sinks.File”， “Serilog.Sinks.Async” ], "最低级别":"调试", “写入：异步”：{ "名称":"异步", “参数”：{ “配置”：[ { "名称":"文件", “参数”：{ "path":"project-log.txt", "rollingInterval":"天" } } ] } } } }
