c# - asp.net core - 从 appsettings.json 设置 Serilog.Exceptions

Question

我需要使用 Serilog.Exceptions 包来捕获异常。从 appsettings.json 读取 Serilog

{
    "Serilog": {
        "Using": [
            "Serilog.Sinks.RollingFile",
            "Serilog.Sinks.Seq"
        ],
        "WriteTo": [
            {
                "Name": "RollingFile",
                "Args": {
                    "restrictedToMinimumLevel": "Debug",
                    "pathFormat": "myPath\\log-{Date}.log"
                }
            },
            {
                "Name": "RollingFile",
                "Args": {
                    "restrictedToMinimumLevel": "Error",
                    "pathFormat": "myPath\\error-{Date}.log"
                }
            },
            {
                "Name": "Seq",
                "Args": {
                    "serverUrl": "myUrl",
                    "apiKey": "myApiKey"
                }
            }
        ],
        "Enrich": [
            "FromLogContext",
            "WithMachineName",
            "WithThreadId"
        ],
        "Properties": {
            "Application": "myApplicationName"
        }
    }
}

在我的startup.cs

var logger = new LoggerConfiguration()
    .Enrich.WithExceptionDetails()
    .ReadFrom.Configuration(Configuration)
    .CreateLogger();

Log.Logger = logger;

但它不起作用。我是否需要在 appsettings.json 中为 Serilog.Exceptions 包添加一些其他属性？还是 appsettings.json 配置正确？我究竟做错了什么？谢谢

以下是我Serilog在ASP.NET Core 2.1. 你可以把它当作清单，看看你错过了什么。

1. 从 Nuget: Serilog.AspNetCore、Serilog.Exceptions和Serilog.Settings.Configuration其他要使用的接收器安装包。

2. Serilog在主程序中设置：

   public class Program
   {
       public static void Main(string[] args)
       {
           CreateWebHostBuilder(args).Build().Run();
       }
   
       public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
           WebHost.CreateDefaultBuilder(args)
               .UseStartup<Startup>()
               .UseSerilog((hostingContext, loggerConfiguration) => 
                   loggerConfiguration
                       .ReadFrom.Configuration(hostingContext.Configuration)
               );
   }
   

3. 把WithExceptionDetails你的Serilog部分放在appsettings.json：

   {
       "Serilog": {
           ...
           "Enrich": [
               "FromLogContext",
               "WithExceptionDetails"
           ],
           ...
       }
   }
