假设我正在使用新的DepencyInjection框架来配置我的类和依赖项在新的ASP.Net/vNext中。那么,我该如何使用并获取我预定义的配置设置呢?
public void ConfigureServices(IServiceCollection services)
{
// Add Application settings to the services container.
services.Configure<AppSettings>(Configuration.GetSubKey("AppSettings"));
// Add EF services to the services container.
services.AddEntityFramework()
.AddSqlServer()
.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(Configuration["Data:DefaultConnection:ConnectionString"]));
// Add Identity services to the services container.
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
// Configure the options for the authentication middleware.
// You can add options for Google, Twitter and other middleware as shown below.
// For more information see http://go.microsoft.com/fwlink/?LinkID=532715
services.Configure<FacebookAuthenticationOptions>(options =>
{
options.AppId = Configuration["Authentication:Facebook:AppId"];
options.AppSecret = Configuration["Authentication:Facebook:AppSecret"];
});
services.Configure<MicrosoftAccountAuthenticationOptions>(options =>
{
options.ClientId = Configuration["Authentication:MicrosoftAccount:ClientId"];
options.ClientSecret = Configuration["Authentication:MicrosoftAccount:ClientSecret"];
});
// Add MVC services to the services container.
services.AddMvc();
services.AddSingleton(a =>
{
//AppSettings settingsModel = ?? //GET CONFIGURATION SETTINGS FILLED
// TECHNICAL ARTIFICE TO RETRIEVE CURRENT SETTINGS
//var settingsModel = new AppSettings();
//var config = Configuration.GetSubKey("AppSettings");
//foreach (var item in typeof(AppSettings).GetProperties().Where(b => b.CanWrite))
{
//item.SetValue(settingsModel, config.Get(item.Name));
}
return new FooService(settingsModel);
});
//Uncomment the following line to add Web API services which makes it easier to port Web API 2 controllers.
//You will also need to add the Microsoft.AspNet.Mvc.WebApiCompatShim package to the 'dependencies' section of project.json.
services.AddWebApiConventions();
}
Configuration.GetSubKey("AppSettings")
传递到FooService构造函数中呢? - Aluan HaddadAppSettings
类,它只是用于配置,并且如果我使用 Configuration.GetSubKey,我将获得一个IConfiguration
对象,这意味着我需要手动获取配置值。 - J. Lennon
