C# Serilog：如何进一步增强appsettings.json中的过滤器表达式？,c#,.net-core,serilog,C#,.net Core,Serilog,我有两个带有Serilog的记录器，它们保存到不同的文件中。我想通过appsettings.json而不是代码来创建记录器 当我通过Startup.cs配置创建日志时，我会得到一个更具体的日志，我更喜欢这样，因为它更清晰，可以让其他人检查日志并了解正在发生的事情，而不需要太多的技术知识。但是，我希望将其应用于appsettings，以便可以将代码迁移到可能使用的任何其他项目。 仅供参考：我不想覆盖日志级别 例如，通过代码，我创建了我的记录器，如下所示： Log.Logger = new Logg

我有两个带有Serilog的记录器，它们保存到不同的文件中。我想通过appsettings.json而不是代码来创建记录器

当我通过
Startup.cs
配置创建日志时，我会得到一个更具体的日志，我更喜欢这样，因为它更清晰，可以让其他人检查日志并了解正在发生的事情，而不需要太多的技术知识。但是，我希望将其应用于appsettings，以便可以将代码迁移到可能使用的任何其他项目。 仅供参考：我不想覆盖日志级别

例如，通过代码，我创建了我的记录器，如下所示：

Log.Logger = new LoggerConfiguration()
    .WriteTo.ColoredConsole()
    .WriteTo.Logger(lc => lc
    .Filter.ByExcluding(Matching.FromSource("Microsoft"))
    .WriteTo.File("Serilogs/Program_log_.txt", rollingInterval: RollingInterval.Day)
    .MinimumLevel.Information()
    .MinimumLevel.Override("Microsoft", LogEventLevel.Information))

    .WriteTo.Logger(lc => lc
    .Filter.ByIncludingOnly(Matching.FromSource("Microsoft"))
    .WriteTo.File("Serilogs/ServerTrace_log_.txt", rollingInterval: RollingInterval.Day)
    .MinimumLevel.Information()
    .MinimumLevel.Override("Microsoft", LogEventLevel.Information))

    .CreateLogger();

 "Serilog": {
    "Using": [
      "Serilog.Sinks.File",
      "Serilog.Filters.Expressions",
      "Serilog.Settings.Configuration"
    ],
    "WriteTo": [
      {
        "Name": "Logger",
        "Args": {
          "configureLogger": {
            "Filter": [
              {
                "Name": "ByIncluding",
                "Args": {
                  "expression": "SourceContext = 'Microsoft'"
                }
              }
            ],
            "WriteTo": [
              {
                "Name": "File",
                "Args": {
                  "path": "./Serilogs/server_logs_.log",
                  "rollingInterval": "Day"
                }
              }
            ]
          }
        }
      },
      {
        "Name": "Logger",
        "Args": {
          "configureLogger": {
            "Filter": [
              {
                "Name": "ByExcluding",
                "Args": {
                  "expression": "SourceContext = 'Microsoft.AspNetCore.Hosting.Internal.WebHost'"
                }
              }
            ],
            "WriteTo": [
              {
                "Name": "File",
                "Args": {
                  "path": "./Serilogs/program_logs_.log",
                  "rollingInterval": "Day"
                }
              }
            ]
          }
        }
      }
    ]
  }
这将生成两个独立的输出，我喜欢它们的格式：

因此，通过应用感觉相同的技术，结果会有所不同，因为
文件1
现在包含更多的操作信息，
文件2
包含堆栈和自定义日志信息，尽管我希望它们完全分开。

我认为您的过滤器不太正确

筛选器表达式应为：

"expression": "SourceContext = 'Microsoft' or StartsWith(SourceContext, 'Microsoft.')"
（我想您可以不使用最后一个点而直接使用（SourceContext，'Microsoft'）启动
StartsWith，但是对于
microsoftoristrially.MyNamespace
）这样的名称空间，这可能会不正常）

（内部
Matching.ForSource
执行
SourceContext.StartsWith（..）
类型的筛选，如图所示）

要确认，您可能需要编辑文件接收器的
outputTemplate
，以显示
SourceContext
属性并查看日志事件的来源。（默认值为
“{Timestamp:yyyy-MM-dd HH:MM:ss.fff-zzz}[{Level:u3}]{Message:lj}{NewLine}{Exception}”
）。您可以将其更改为
“{Timestamp:yyyy-MM-dd HH:MM:ss.fff-zzz}[{Level:u3}]{Message:lj}{NewLine}{Exception}”
以包含
SourceContext
属性




顺便说一下，您有一个额外的、不需要的
“Using”
指令。
“Serilog.Settings.Configuration”
是不必要的
“表达式”：“StartsWith（SourceContext，'Microsoft.'）”
这样做的结果似乎与我所做的方式相同，我已更改以符合标准的要求。谢谢你。如果他们做了同样的事情，或者你可以限定多个过滤器我不好，我认为你应该做两个“同等”的微软，或者从微软开始（用一个点）。。。我将更新我的回答，但仍然没有表现出完全相同的行为，这让我觉得奇怪，因为通过该方法它感觉是一样的？您是否正确地在两个过滤器中使用完全相同的表达式（一次
仅包括
，一次
排除
）？奇怪<代码>“名称”：“ByIncludingOnly”、
和
“名称”：“ByIncludingOnly”、
任何替代方法似乎都会破坏它，从而重复

文件2的日志
