Serilog.Sinks.MSSqlServer未填充自定义列

我环顾四周，但我找不到一个有效的解决方案，因为所有的例子看起来都很相似，我认为一定是我忽略了一些明显的东西 . 另请注意，这是我第一个使用.NET Core和Serilog的真实项目 .

问题

我正在尝试将（使用serilog）一些自定义属性记录到 appsettings.json 中定义的数据库中的自己的列中，并通过管道上的中间件添加 . 但是值仍然为NULL，即使在属性XML列中正确填充了相同的项 .

所以我为经过身份验证的用户提供了预期的新属性：

<properties>
    <property key="UserId">ff88ddb9-6f5a-4ad5-a2a8-1d016ff99398</property>
    <property key="UserName">ernst</property>
<properties>

但是我想将这些值添加到它们自己的列以及一些查询优化中 .

代码

代码是.NET Core 2.1，我设置了Serilog，如https://github.com/serilog/serilog-aspnetcore/blob/dev/samples/SimpleWebSample/Program.cs所示：

private 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()
      .ReadFrom.Configuration(Configuration)
      .Enrich.FromLogContext()
      .MinimumLevel.Debug()
      .CreateLogger();
  try 
  {
    Log.Information($"Starting web host in {Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"} environment, version {Util.Version.Long}");
    BuildWebHost(args).Run();
    return 0;
  }
  catch (Exception ex)
  {
    Log.Fatal(ex, "Host terminated unexpectedly");
    return 1;
  }
  finally
  {
    Log.CloseAndFlush();
  }
}

 private static IWebHost BuildWebHost(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseStartup<Startup>()
                .UseConfiguration(Configuration)
                .UseSerilog()
                .CaptureStartupErrors(true)
                .Build();

要添加信息，我在中间件中使用 LogContext.PushProperty .

配置的相关部分：

"Serilog": {
    "Using": [ "Serilog.Sinks.MSSqlServer" ],
    "MinimumLevel": "Debug",
    "Enrich": [ "FromLogContext", "WithMachineName", "WithThreadId" ],
    "WriteTo": [
      {
        "Name": "MSSqlServer",
        "Args": {
          "connectionString": "Data Source=localhost;Database=MyDb;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False;ApplicationIntent=ReadWrite;MultiSubnetFailover=False",
          "tableName": "SeriLog_Custom",
          "autoCreateSqlTable": true,
          "restrictedToMinimumLevel": "Information",
          "columnOptionsSection": {
            "customColumns": [
              {
                "ColumnName": "UserId",
                "DataType": "nvarchar",
                "DataLength": 450,
                "AllowNull": true
              },
              {
                "ColumnName": "UserName",
                "DataType": "nvarchar",
                "DataLength": 256,
                "AllowNull": true

              }
            ]
          }
        }
      }
    ]
  }

此外，除了不填充自定义列之外，数据库也是以标准方式创建的，没有这些列，因此我手动添加了它们 .

这可能指向配置问题？

用于创建表的SQL：

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[SeriLog_Custom](
    [Id] [int] IDENTITY(1,1) NOT NULL,
    [Message] [nvarchar](max) NULL,
    [MessageTemplate] [nvarchar](max) NULL,
    [Level] [nvarchar](128) NULL,
    [TimeStamp] [datetime] NOT NULL,
    [Exception] [nvarchar](max) NULL,
    [Properties] [xml] NULL,
    [UserId] [nvarchar](450) NULL,
    [UserName] [nvarchar](256) NULL,
 CONSTRAINT [PK_SeriLog_Custom] PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

现在我可以获得所需的信息：

SELECT [Id]
      ,[Message]
      ,[MessageTemplate]
      ,[Level]
      ,[TimeStamp]
      ,[Exception]
      ,[UserId]
      ,[UserName]
      ,[Properties].value('(//property[@key="UserName"]/node())[1]', 'nvarchar(max)') as UserName
      ,[Properties]
  FROM [ECSControl].[dbo].[SeriLog_ECMonitor]
  where [Properties].value('(//property[@key="UserName"]/node())[1]', 'nvarchar(max)') = 'ernst'
  order by id desc;

但是我想通过以下方式访问它：

SELECT [Id]
      ,[Message]
      ,[MessageTemplate]
      ,[Level]
      ,[TimeStamp]
      ,[Exception]
      ,[UserId]
      ,[UserName]
      ,[Properties]
  FROM [ECSControl].[dbo].[SeriLog_ECMonitor]
  where  UserName = 'ernst'
  order by id desc;
