ConsoleLoggerExtensions.AddConsole(ILoggerFactory)已过时代码修复

0x00.问题

netcoreapp2.2环境下， Startup.cs 代码配置如下

  public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
   {
       loggerFactory.AddConsole();

        //……
   }

运行输出警告：“ConsoleLoggerExtensions.AddConsole(ILoggerFactory)”已过时:“This method is obsolete and will be removed in a future version. The recommended alternative is AddConsole(this ILoggingBuilder builder).”

官方文档也注明此API已经过时。 https://docs.microsoft.com/zh-cn/dotnet/api/microsoft.extensions.logging.consoleloggerextensions.addconsole?view=aspnetcore-2.2#Microsoft_Extensions_Logging_ConsoleLoggerExtensions_AddConsole_Microsoft_Extensions_Logging_ILoggingBuilder_

0x01.推荐方法

Program.cs  配置如下

 public class Program
 {
     public static void Main(string[] args)
     {
         CreateWebHostBuilder(args).Build().Run();
     }

     public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
         WebHost.CreateDefaultBuilder(args)
             .UseStartup<Startup>()
             .ConfigureLogging((hostingContext, logging) =>
             {
                 logging.AddConfiguration(hostingContext.Configuration.GetSection("Logging"));
                 logging.AddConsole();
                 logging.AddDebug();
             });
 }

或者 Startup.cs  ConfigureServices方法中配置如下

 public void ConfigureServices(IServiceCollection services)
 {
     services.AddLogging(logging =>
     {
         logging.AddConsole();
         logging.AddDebug();
     }); 

     //……
 }
