ASP.NET Core 2.0 WebApi全局配置及日志实例

然后在程序中就可以开始调用日志功能了。

二个功能的DEMO代码如下：

using System;
using System.IO;
using Microsoft.Extensions.Configuration;
using NLog.Extensions.Logging;
using NLog.Web;
public class Program
{
 public static IConfigurationRoot Configuration { get; set; }
 public static NLog.Logger log = NLog.LogManager.GetCurrentClassLogger();
 public static void ConfigAndLog()
 {
  var builder = new ConfigurationBuilder()
   .SetBasePath(Directory.GetCurrentDirectory())
   .AddJsonFile("appsettings.json");
  Configuration = builder.Build();
  string app_key = Configuration["appSettings:app_key"];
  string coon = Configuration["connectionStrings:conn"];
  log.Debug("数据库连接为：" + conn);
  return;
 }
}
