如何在外部 JSON 配置文件中配置 Serilog 的 ContainsKey-Filter？

Question

如何在外部 applicationsettings.json 文件中配置过滤器 lc.Filter.ByIncludingOnly(lc => lc.Properties.ContainsKey("log_gp")？我试过了

  "Filter": [
    {
      "Name": "ByIncludingOnly",
      "Args": {
        "expression": "Contains(Properties, 'log_gp')"
      }
    }
  ]

但没有成功。谢谢

Answer 1

dotnet add package serilog.expressions

然后：

  "Using": ["Serilog.Expressions"],
  "Filter": [
    {
      "Name": "ByIncludingOnly",
      "Args": {
        "expression": "IsDefined(log_gp)"
      }
    }
  ]
