在AppSettings.json中为Serilog Sinks MsSqlServer配置列选项

我'm trying to determine if it'可以在 appsettings.json 文件中为ASP.Net Core 2项目配置serilog sink mssqlserver的列选项 .

我在 Program.cs 文件中创建并配置 Logger .

public static IConfiguration Configuration { get; } = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
            .AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"}.json", optional: true)
            .AddEnvironmentVariables()
            .Build();

        public static int Main(string[] args)
        {



            Log.Logger = new LoggerConfiguration()
                //.Enrich.WithProperty("AppName", "One Badass App") // Adds property to XML structure in properties column
                .ReadFrom.Configuration(Configuration)
                .CreateLogger();

                try
                {
                    Log.Information("Starting web host");
                    BuildWebHost(args).Run();
                    return 0;
                }
                catch (Exception ex)
                {
                    Log.Fatal(ex, "Host terminated unexpectedly");
                    return 1;
                }
                finally
                {
                    Log.CloseAndFlush();
                }
        }

我可以从appsettings.json文件构建配置文件，该文件包含一个Serilog节点，其中包含要使用的连接字符串和表的信息 .

{
  "AppSettings": {
    "Application": {
      "Name": "Payment Processing API",
      "Version":  "1.0"
    }
  },
  "ConnectionStrings": {
    "localPaymentProcessingDb": "Server=(localdb)\\mssqllocaldb;Database=PaymentProcessing;Trusted_Connection=True;MultipleActiveResultSets=true"
  },
  "Serilog": {
    "MinimumLevel": "Information",
    "WriteTo": [
      {
        "Name": "MSSqlServer",
        "Args": {
          "connectionString": "Server=(localdb)\\mssqllocaldb;Database=PaymentProcessing;Trusted_Connection=True;MultipleActiveResultSets=true",
          "tableName": "Logs"
        }
      }
    ]
 }

Github上有一个未解决的问题，但我没有找到任何其他相关信息 .

如果无法在 appsettings.json 中配置列选项，那么在ASP.Net Core 2项目中应该在何处以及如何配置它们？

asp.net-core-2.0 appsettings serilog

    要从Code中的appsettings访问Serilog，您可以将Serilog节点绑定到Serilog类 .
    以下是详细步骤 .
    1.创建Serilog配置类

    public class SerilogConfiguration
{
    public LogEventLevel MinimumLevel { get; set; }
    public List<WriteTo> WriteTo { get; set; }
}
public class WriteTo
{
    public string Name { get; set; }
    public Args Args { get; set; }
}
public class Args
{
    public string ConnectionString { get; set; }
    public string TableName { get; set; }
    public List<StandardColumn> Add { get; set; }
    public List<StandardColumn> Remove { get; set; }
}
    • 配置appsettings.json

    码：

    {
    "Serilog": {
    "MinimumLevel": "Error",
    "WriteTo": [
      {
        "Name": "MSSqlServer",
        "Args": {
          "connectionString": "<our connection string>",
          "tableName": "Log",
          "Remove": [ "Properties" ],
          "Add": [ "LogEvent" ]
        }
      }
    ]
  }
}
    • 将appsetting.json绑定到类
    public void ConfigureServices(IServiceCollection services)
{           
    services.Configure<SerilogConfiguration>(Configuration.GetSection("Serilog"));            
}
    • 访问配置
    public class HomeController : Controller    {
private readonly SerilogConfiguration _configuration;
public HomeController(IOptions<SerilogConfiguration> configuration)
{
    _configuration = configuration.Value;
}       

public IActionResult AppSettings()
{
    var columnOptions = new ColumnOptions();
    var MSSqlServer = _configuration.WriteTo.Where(wt => wt.Name == "MSSqlServer").FirstOrDefault();
    // Don't include the Properties XML column.
    foreach(var columnRemove in MSSqlServer.Args.Remove)
    {
        columnOptions.Store.Remove(columnRemove);
    }
    // Do include the log event data as JSON.
    foreach (var columnAdd in MSSqlServer.Args.Add)
    {
        columnOptions.Store.Add(columnAdd);
    }

    Log.Logger = new LoggerConfiguration()
        .WriteTo.MSSqlServer(MSSqlServer.Args.ConnectionString, MSSqlServer.Args.TableName, columnOptions: columnOptions,
            restrictedToMinimumLevel: _configuration.MinimumLevel)
        .CreateLogger();
    return Ok("OK");
}    }
