c# - Serilog 多个文件 appsettings.json

问题描述

我试图将 serilog 配置为写入多个文件，但没有任何运气。使用此配置它只是写入第二个文件？

{
  "AllowedHosts": "*",
  "Serilog": {
    "Using": [ "Serilog.Sinks.File" ],
    "MinimumLevel": "Debug",
    "WriteTo": [
      {
        "Name": "File",
        "Args": {
          "path": "c:\\temp\\audit-.log",
          "rollingInterval": "Day",
          "restrictedToMinimumLevel": "Information"
        }
      },
      {
        "Name": "File",
        "Args": {
          "path": "c:\\temp\\error-.log",
          "rollingInterval": "Day",
          "restrictedToMinimumLevel": "Error"
        }
      }
    ]
  }
}

或者有什么方法可以从 appsettings.json 将许多记录器加载到具有不同配置的软件中。像这样的东西？

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

_log = new LoggerConfiguration()
    .ReadFrom
    .Configuration(errorLogConfiguration)
    .CreateLogger();

解决方案

我找到了解决方案。为 appsettings.json、ErrorLog 和 AuditLog 创建了单独的部分。

  "ErrorLog": {
    "Using": [ "Serilog.Sinks.File" ],
    "MinimumLevel": "Debug",
    "WriteTo": [
      {
        "Name": "File",
        "Args": {
          "path": "c:\\temp\\error-.log",
          "rollingInterval": "Day",
          "restrictedToMinimumLevel": "Error"
        }
      }
    ]
  },
  "AuditLog": {
    "Using": [ "Serilog.Sinks.File" ],
    "MinimumLevel": "Debug",
    "WriteTo": [
      {
        "Name": "File",
        "Args": {
          "path": "c:\\temp\\audit-.log",
          "rollingInterval": "Day",
          "restrictedToMinimumLevel": "Information"
        }
      }
    ]
  }

现在我可以创建 2 个单独的记录器：

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

            var errorSection = errorLogConfiguration.GetSection("ErrorLog");
            var auditSection = errorLogConfiguration.GetSection("AuditLog");

            _log = new LoggerConfiguration()
                .ReadFrom
                .ConfigurationSection(errorSection)
                .CreateLogger();

            _auditLog = new LoggerConfiguration()
                .ReadFrom
                .ConfigurationSection(auditSection)
                .CreateLogger();

哪个更适合我的需要。
