.NET Core项目中 Serilog日志文件配置

一、安装需要的NuGet包

dotnet add package Serilog.AspNetCore

二、在 Program.cs 中配置 Serilog

//日志创建规则
Log.Logger = new LoggerConfiguration()
    .WriteTo.Console()
    .WriteTo.File("Logs/log-.txt", rollingInterval: RollingInterval.Day)
    .CreateLogger();


var builder = WebApplication.CreateBuilder(args);

builder.Host.UseSerilog();

//从配置文件中的读取 Serilog 配置
Log.Logger = new LoggerConfiguration()
    .ReadFrom.Configuration(builder.Configuration)
    .CreateLogger();


var app = builder.Build();

// 其他中间件和配置
app.Run();

三、在 appsettings.json 中添加 Serilog 配置

"Serilog": {
  "MinimumLevel": "Information",
  "WriteTo": [
    { "Name": "Console" },
    {
      "Name": "File",
      "Args": {
        "path": "Logs/log-.txt",
        "rollingInterval": "Day"
      }
    }
  ]
},

四、Serilog的使用

4.1 在你的控制器或服务中注入 ILogger<T>：

/// <summary>
/// Mes系统Api对接
/// </summary>
[Route("api/[controller]")]
[ApiController]
public class MesController : Controller
{
    private readonly ILogger<MesController> _logger;
    private readonly IMesService _mesService;

    public MesController(ILogger<MesController> logger,IMesService mesService)
    {
        _logger = logger;
        _mesService = mesService;
    }

    /// <summary>
    /// 订单包装数据返回
    /// </summary>
    /// <param name="model">WMS的数据结构</param>
    /// <returns></returns>
    [HttpPost("PostBackOrderPack")]
    public async Task<MessageResponse<string>> PostBackOrderPack(List<OrderPackDto> model)
    {
        try
        {
            var result = await _mesService.EditOrderPackDetailList(model);
            _logger.LogInformation("订单包装数据返回:" + result);
            return new MessageResponse<string>
            {
                Status = 200,
                Message = "获取成功",
                Success = true,
                Response = result
            };
        }
        catch (Exception ex)
        {
            _logger.LogWarning("订单包装数据返回异常："+model);
            return new MessageResponse<string>
            {
                Status = 500,
                Message = $"接口异常：{ex}",
                Success = false,
            };
        }
    }
}

4.2 使用 Serilog 的 Log 静态类

//引用Serilog库
using Serilog;

//具体方法中使用
Log.Information("这是一个信息日志");
Log.Error("这是一个错误日志");

五、使用效果

在项目文件夹下会生成一个Logs文件夹，里面会存储对应的log文件
