Asp.net WebAPI Ioc

网上关于webapi Ioc 的东西很多，如http://efmvc.codeplex.com/SourceControl/latest#MyFinance.Web/Global.asax.cs 这是用微软IUnityContainer。还有：

ASP.NET Web API和依赖注入

但是网上关于Autofac 确是很少，我第一次接触也是单元测试的时候 ASP.NET Web API Unit Testing

这里就简单贴点code吧：

 public class Startup    {        public void Configuration(Owin.IAppBuilder appBuilder)        {            var config = new HttpConfiguration();            config.MessageHandlers.Add(new HeaderAppenderHandler());            config.MessageHandlers.Add(new EndRequestHandler());            config.Filters.Add(new ArticlesReversedFilter());            config.Services.Replace(typeof(IAssembliesResolver), new CustomAssembliesResolver());            config.Routes.MapHttpRoute(                name: "DefaultApi",                routeTemplate: "api/{controller}/{id}",                defaults: new { id = RouteParameter.Optional }            );            config.MapHttpAttributeRoutes();            // Autofac configuration            var builder = new ContainerBuilder();            builder.RegisterApiControllers(typeof(ArticlesController).Assembly);            //builder.RegisterAssemblyTypes(Assembly.GetExecutingAssembly())            //      .Where(t =>!t.IsAbstract && typeof(ApiController).IsAssignableFrom(t));            // Unit of Work            var _unitOfWork = new Mock<IUnitOfWork>();            builder.RegisterInstance(_unitOfWork.Object).As<IUnitOfWork>();            //Repositories            var _articlesRepository = new Mock<IArticleRepository>();            _articlesRepository.Setup(x => x.GetAll()).Returns(                    BloggerInitializer.GetAllArticles()                );            builder.RegisterInstance(_articlesRepository.Object).As<IArticleRepository>();            var _blogsRepository = new Mock<IBlogRepository>();            _blogsRepository.Setup(x => x.GetAll()).Returns(                BloggerInitializer.GetBlogs                );            builder.RegisterInstance(_blogsRepository.Object).As<IBlogRepository>();            // Services            builder.RegisterAssemblyTypes(typeof(ArticleService).Assembly)               .Where(t => t.Name.EndsWith("Service"))               .AsImplementedInterfaces().InstancePerRequest();            builder.RegisterInstance(new ArticleService(_articlesRepository.Object, _unitOfWork.Object));            builder.RegisterInstance(new BlogService(_blogsRepository.Object, _unitOfWork.Object));            IContainer container = builder.Build();            config.DependencyResolver = new AutofacWebApiDependencyResolver(container);            appBuilder.UseWebApi(config);        }    }

我这里是单元测试，所以安装包如下：

<?xml version="1.0" encoding="utf-8"?><packages><package id="EntityFramework" version="6.1.3" targetFramework="net45" />  <package id="Autofac" version="3.5.0" targetFramework="net45" />  <package id="Autofac.WebApi2" version="3.4.0" targetFramework="net45" />  <package id="Microsoft.AspNet.WebApi.Client" version="5.2.3" targetFramework="net45" />  <package id="Microsoft.AspNet.WebApi.Core" version="5.2.3" targetFramework="net45" />  <package id="Microsoft.AspNet.WebApi.Owin" version="5.2.3" targetFramework="net45" />  <package id="Microsoft.AspNet.WebApi.SelfHost" version="5.2.3" targetFramework="net45" />  <package id="Microsoft.Owin" version="3.0.1" targetFramework="net45" />  <package id="Microsoft.Owin.Host.HttpListener" version="3.0.1" targetFramework="net46" />  <package id="Microsoft.Owin.Hosting" version="3.0.1" targetFramework="net46" />  <package id="Owin" version="1.0" targetFramework="net45" />  <package id="Moq" version="4.2.1510.2205" targetFramework="net45" />  <package id="Newtonsoft.Json" version="6.0.4" targetFramework="net45" />  <package id="NUnit" version="3.2.0" targetFramework="net45" />  <package id="NUnitTestAdapter" version="2.0.0" targetFramework="net45" /> </packages>

测试的时候建议使用 TestDriven.NET
