如何为 .NET Core 3.0 Worker Service 设置 serilog SEQ

Question

日志记录正在运行，但没有发布到我的本地 seq，我尝试添加 serilog 并使用 Serilog 但它没有登录到我的本地服务：相关问题

.csproj

<ItemGroup>
<PackageReference Include="Microsoft.AspNet.Mvc" Version="5.2.7" />
<PackageReference Include="Microsoft.Extensions.Hosting" Version="3.0.0" />
<PackageReference Include="Npgsql.EntityFrameworkCore.PostgreSQL" Version="3.0.1" />
<PackageReference Include="Serilog" Version="2.8.0" />
<PackageReference Include="Serilog.AspNetCore" Version="3.0.0" />
<PackageReference Include="Serilog.Extensions.Hosting" Version="3.0.0" />
<PackageReference Include="Serilog.Extensions.Logging" Version="3.0.1" />
<PackageReference Include="Serilog.Settings.Configuration" Version="3.1.0" />
<PackageReference Include="Serilog.Sinks.Console" Version="3.1.1" />
<PackageReference Include="System.Configuration.ConfigurationManager" Version="4.6.0" />

程序

public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureLogging(loggingBuilder => {
                loggingBuilder.AddEventLog();
                loggingBuilder.AddSerilog();
            })
            .ConfigureServices((hostContext, services) =>
            {
                services.AddHostedService<Worker>();
            })
            .UseSerilog();

appSettings.json：

"Serilog": {
"LevelSwitches": { "$controlSwitch": "Verbose" },
"MinimumLevel": { "ControlledBy": "$controlSwitch" },
"WriteTo": [
  {
    "Name": "Seq",
    "Args": {
      "serverUrl": "http://localhost:5341",
      "apiKey": "yeEZyL3SMcxEKUijBjN",
      "controlLevelSwitch": "$controlSwitch"
    }
  }
]

}

我是否缺少一些配置或任何 Nuget 包？我已经成功地在 ASP.NET Core API 中使用了 seq，但到目前为止还不能在工作服务中使用它。

在花了更多时间弄清楚之后，问题是 appsettings 设置以及我注入记录器的方式

<ItemGroup>
<PackageReference Include="Microsoft.AspNet.Mvc" Version="5.2.7" />
<PackageReference Include="Microsoft.Extensions.Hosting" Version="3.0.0" />
<PackageReference Include="Npgsql.EntityFrameworkCore.PostgreSQL" Version="3.0.1" />
<PackageReference Include="Serilog" Version="2.8.0" />
<PackageReference Include="Serilog.AspNetCore" Version="3.0.0" />
<PackageReference Include="Serilog.Extensions.Hosting" Version="3.0.0" />
<PackageReference Include="Serilog.Extensions.Logging" Version="3.0.1" />
<PackageReference Include="Serilog.Settings.Configuration" Version="3.1.0" />
<PackageReference Include="Serilog.Sinks.Console" Version="3.1.1" />
<PackageReference Include="Serilog.Sinks.Seq" Version="4.0.0" />
<PackageReference Include="System.Configuration.ConfigurationManager" Version="4.6.0" />

Host.CreateDefaultBuilder(args)
            .ConfigureLogging(loggingBuilder =>
            {
                var configuration = new ConfigurationBuilder()
                    .AddJsonFile("appsettings.json")
                    .Build();
                var logger = new LoggerConfiguration()
                    .ReadFrom.Configuration(configuration)
                    .CreateLogger();
                loggingBuilder.AddSerilog(logger, dispose: true);
            })

设置：

"Serilog": {
"LevelSwitches": { "$controlSwitch": "Verbose" },
"MinimumLevel": { "ControlledBy": "$controlSwitch" },
"WriteTo": [
  {
    "Name": "Seq",
    "Args": {
      "serverUrl": "http://localhost:5341",
      "apiKey": "yeEZyL3SMcxEKUijBjN",
      "controlLevelSwitch": "$controlSwitch"
    }
  }
]
