c# - 共享启动配置 dotnet core 2 WebAPI

Question

在具有多个 API 的项目上工作，我们希望共享配置以确保每个 API 具有相同的记录器配置等，并且我们可以将所有 nuget 包保留在扩展类项目中。

使用扩展来实现，是实现共享启动配置的好方法吗？有没有更好的办法？

扩展类。

namespace Extensions
{
    public static class Extensions
    {
        public static IServiceCollection AddExtensionsConfig(this IServiceCollection services)
        {
            services.AddLoggerConfig();
            services.AddMvc();

            return services;
        }

        public static IApplicationBuilder UseExtensionsConfig(this IApplicationBuilder app)
        {
            //use logger
            app.UseLoggerConfig();

            // auth
            app.UseAuthentication();

            // set startup file to index.html for easy testing
            app.UseDefaultFiles();

            //enable CORS
            app.UseCorsConfig();

            //added support for static file
            app.UseStaticFiles();

            app.UseMvc();

            return app;
        }
    }
}

记录器扩展

namespace Extensions.Logger
{
    public static class LoggerServiceExtensions
    {
        public static IServiceCollection AddLoggerConfig(this IServiceCollection services)
        {
            //serilog
            services.AddLogging(loggingBuilder =>
             loggingBuilder.AddSerilog(dispose: true));

            var loggerServices = new ServiceCollection()
               .AddLogging(builder =>
               {
                   builder.AddSerilog();
               });

            return services;
        }

        public static IApplicationBuilder UseLoggerConfig(this IApplicationBuilder app)
        {
            //add serilog https://github.com/serilog/serilog-extensions-logging
            // https://github.com/serilog/serilog-extensions-logging/blob/dev/samples/Sample/Program.cs
            Log.Logger = new LoggerConfiguration()
            .Enrich.FromLogContext()
            .WriteTo.File("log.txt", rollingInterval: RollingInterval.Day)
            .CreateLogger();

            var startTime = DateTimeOffset.UtcNow;

            Log.Logger.Information("Started at {StartTime} and 0x{Hello:X} is hex of 42", startTime, 42);

            return app;
        }
    }
}

然后在Startup ConfigureServices

// add config
services.AddExtensionsConfig();

和启动配置方法

// use config
app.UseExtensionsConfig();

Using extensions to achieve this, is good way to achieve a shared startup configuration ? Is there a better way ?

这是目前推荐的方法。您还将在提供的大多数示例和第三部分扩展中看到这种模式。 asp.net-core 的模块化特性允许这种首选方法
