dotnet core 2.1 添加serilog

1、引用以下包

2、在Program.cs中修改如下：

public static void Main(string[] args)
{
    Log.Logger = new LoggerConfiguration()
      .MinimumLevel.Error()
      .MinimumLevel.Override("Microsoft", LogEventLevel.Error)
      .WriteTo.File(Path.Combine("Logs", "log"), rollingInterval: RollingInterval.Day)
      .CreateLogger();
    BuildWebHost(args).Run();
}

public static IWebHost BuildWebHost(string[] args) =>
  WebHost.CreateDefaultBuilder(args)
      .ConfigureLogging((hostingContext, config) =>
      {
          config.ClearProviders();  //Disabling default integrated logger
          _environmentName = hostingContext.HostingEnvironment.EnvironmentName;
      })
      .UseStartup<Startup>()
      .UseSerilog()
      .Build();

3、在controller使用

public AuthController(ModelContext context,ILogger<AuthController> logger)
{
    _context = context;
    _logger = logger;
}


_logger.LogError(ex.Message);

注意：

如有使用 Authorize 验证，不要设置在controller上，即使token正确也会报401，需要设置在action上
