如何在.net6上的程式檔案中使用啟動類？

我正在開發 ASP.NET Core 2.2 Web 應用程式。將我的應用程式升級到 .NET 6 時遇到一些問題。

我的問題是 .NET 6.0 中沒有startup類，我program.cs只找到了檔案。

我在我的網路應用程式上添加了啟動類，但我不知道如何在里面使用它Program.cs。

如何startup在 my 中添加或使用類program.cs？

這是startup.cs.NET Core 2.2 中的檔案：

public class Startup
{
        private readonly IConfigurationRoot configRoot;
        private AppSettings AppSettings { get; set; }

        public Startup(IConfiguration configuration)
        {
            Log.Logger = new LoggerConfiguration().ReadFrom.Configuration(configuration).CreateLogger();
            Configuration = configuration;

            IConfigurationBuilder builder = new ConfigurationBuilder().SetBasePath(Directory.GetCurrentDirectory()).AddJsonFile("appsettings.json");
            configRoot = builder.Build();

            AppSettings = new AppSettings();
            Configuration.Bind(AppSettings);
        }

        public IConfiguration Configuration { get; }

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddController();
            services.AddDbContext(Configuration, configRoot);
            services.AddIdentityService(Configuration);

            services.AddAutoMapper();

            services.AddScopedServices();
            services.AddTransientServices();

            services.AddSwaggerOpenAPI();
            services.AddMailSetting(Configuration);
            services.AddServiceLayer();
            services.AddVersion();

            services.AddHealthCheck(AppSettings, Configuration);
            services.AddFeatureManagement();
        }

        public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory log)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseCors(options =>
                 options.WithOrigins("http://localhost:3000")
                 .AllowAnyHeader()
                 .AllowAnyMethod());

            app.ConfigureCustomExceptionMiddleware();

            log.AddSerilog();

            //app.ConfigureHealthCheck();

            app.UseRouting();
            app.UseAuthentication();
            app.UseAuthorization();
            app.ConfigureSwagger();

            app.UseHealthChecks("/healthz", new HealthCheckOptions
            {
                Predicate = _ => true,
                ResponseWriter = UIResponseWriter.WriteHealthCheckUIResponse,
                ResultStatusCodes =
                {
                    [HealthStatus.Healthy] = StatusCodes.Status200OK,
                    [HealthStatus.Degraded] = StatusCodes.Status500InternalServerError,
                    [HealthStatus.Unhealthy] = StatusCodes.Status503ServiceUnavailable,
                },
            }).UseHealthChecksUI(setup =>
              {
                  setup.ApiPath = "/healthcheck";
                  setup.UIPath = "/healthcheck-ui";
                  //setup.AddCustomStylesheet("Customization/custom.css");
              });

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
            });
        }
}

這是我的 .NET 6 program.cs：

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorPages();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthorization();

app.MapRazorPages();

app.Run();

如何使用startup類中的program.cs類？

更新帖子 一切正常但配置服務不作業因為我不知道如何ILoggerFactory 實施startup

 public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory log)
        {
        }

在 program.cs 上

startup.Configure(app, app.Environment,???);

如何將記錄器工廠添加為第三個引數program.cs ILoggerFactory是在類中 更新它解決了使用

var app = builder.Build();
startup.Configure(
    app,
    builder.Environment,
    app.Services.GetRequiredService<FooService>(),
    app.Services.GetRequiredService<ILoggerFactory>()
);

你能告訴我如何應用 swagger ui 來檢查我的 api

uj5u.com熱心網友回復：

您可以手動實體化Startup并手動呼叫方法ConfigureServicesand Configure：

var builder = WebApplication.CreateBuilder(args);

var startup = new Startup(builder.Configuration);
startup.ConfigureServices(builder.Services);

var app = builder.Build();
startup.Configure(app, builder.Environment);

在 ASP.NET Core 2.* 中，Startup.Configure接受注入服務：

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        ...
        services.AddSingleton<IFooService, FooService>();
    }

    public void Configure(WebApplication app, IWebHostEnvironment env, IFooService fooService, ILoggerFactory loggerFactory)
    {

       fooService.Init();
       ...
    }
}

那么你也能 ：

var app = builder.Build();
startup.Configure(
    app,
    builder.Environment,
    app.Services.GetRequiredService<FooService>(),
    app.Services.GetRequiredService<ILoggerFactory>()
);

當我遷移我的 API 時，首先我考慮重用Startup類......但最后我在擴展方法中移動了配置。
