asp.net core web api NLog保存日志为Json

具体怎么实现的不清楚，我只知道怎么用。官方的看不大懂，附上链接有需要的可自行查看

GitHub地址：JsonLayout · NLog/NLog Wiki · GitHub

第一步、引入包

    <PackageReference Include="NLog" Version="5.0.4" />
    <PackageReference Include="NLog.Web.AspNetCore" Version="5.1.4" />

第二步、创建nlog.config文件，文件内容如下

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      autoReload="true"
      internalLogLevel="Info"
      internalLogFile="D:\temp\internal-nlog-AspNetCore.txt">

	<!-- enable asp.net core layout renderers -->
	<extensions>
		<add assembly="NLog.Web.AspNetCore"/>
	</extensions>

	<!-- the targets to write to -->
	<targets>
		<target name="jsonFile" xsi:type="File" fileName="log-file.json" >
			<layout xsi:type="JsonLayout">
				<attribute name="time" layout="${longdate}" />
				<attribute name="level" layout="${level:upperCase=true}"/>
				<attribute name="message" layout="${message}" />
			</layout>
		</target>
	</targets>

	<!-- rules to map from logger name to target -->

	<rules>
		<logger name="testjson.*" minlevel="Trace" writeTo="jsonFile" />
	</rules>
</nlog>

第三步、修改Program.cs

using NLog.Web; //引入

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.

builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

builder.Logging.ClearProviders();//添加
builder.Host.UseNLog();//添加

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();

app.UseAuthorization();

app.MapControllers();

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}"); //这个必须添加


app.Run();

第四步、在控制器中使用

using Microsoft.AspNetCore.Mvc;

namespace testjson.Controllers
{
    [ApiController]
    [Route("[controller]")]
    public class WeatherForecastController : ControllerBase
    {

        private readonly ILogger<WeatherForecastController> _logger;//依赖注入日志

        public WeatherForecastController(ILogger<WeatherForecastController> logger)
        {
            _logger = logger;
        }

        [HttpGet]
        public IEnumerable<string> Get()
        {
            _logger.LogDebug("成功了");
            _logger.LogError("看是不是成功了");


            return new string[] { "Cool", "Weather" };

        }
    }
}
