创建一个叫 UnitTesingWebAPI的空白的解决方案，并包含下列项目：

1. UnitTestingWebAPI.Domain：类库(包含 Entity Models)

2. UnitTestingWebAPI.Data：类库(包含 Repositories)

3. UnitTestingWebAPI.Services：类库(包含 Services)

4. UnitTestingWebAPI.API.Core：类库(包含WebAPI组件，例如：Controllers, Filters, Massage Handlers)

5. UnitTestingWebAPI.API：空的ASP.NET Web Application(Web程序去管控(host) WebAPI

6. UnitTestingWebAPI.Tests：类库(包含单元测试)

Domain 层：

Articles.cs

public class Article
{
    public int ID { get; set; }
    public string Title { get; set; }
    public string Contents { get; set; }
    public string Author { get; set; }
    public string URL { get; set; }
    public DateTime DateCreated { get; set; }
    public DateTime DateEdited { get; set; }

    public int BlogID { get; set; }
    public virtual Blog Blog { get; set; }

    public Article()
    {
    }
}

Blog.cs

public class Blog
{
    public int ID { get; set; }
    public string Name { get; set; }
    public string URL { get; set; }
    public string Owner { get; set; }
    public DateTime DateCreated { get; set; }
    public virtual ICollection
 Articles { get; set; }

    public Blog()
    {
        Articles = new HashSet
();
    }
}

Respository 层：
为UnitTestingWebAPI.Data安装Entity Framework，有两种方式：

1：在UnitTestingWebAPI.Data上右键，点击管理Nuget包，选择对话窗口的左边选择在线包，找到EF进行安装

2：命令行：

install-package EntityFramework

注：一定要注意我用红色圈住的地方。

添加下面的类：

Web API Core 组件

在UnitTestingWebAPI.API.Core 上添加 UnitTestingWebAPI.API.Domain 和UnitTestingWebAPI.Service 项目，并安装下面的包(方法和前面Resporities层一样):

1. Entity Framework

2. Microsoft.AspNet.WebApi.Core

3. Microsoft.AspNet.WebApi.Client

添加下面的Web API Controller到 Controller 文件夹中：

Controllers/ArticlesController.cs

public class ArticlesController : ApiController
{
    private IArticleService _articleService;

    public ArticlesController(IArticleService articleService)
    {
        _articleService = articleService;
    }

    // GET: api/Articles
    public IEnumerable
 GetArticles()
    {
        return _articleService.GetArticles();
    }

    // GET: api/Articles/5
    [ResponseType(typeof(Article))]
    public IHttpActionResult GetArticle(int id)
    {
        Article article = _articleService.GetArticle(id);
        if (article == null)
        {
            return NotFound();
        }

        return Ok(article);
    }

    // PUT: api/Articles/5
    [ResponseType(typeof(void))]
    public IHttpActionResult PutArticle(int id, Article article)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        if (id != article.ID)
        {
            return BadRequest();
        }

        _articleService.UpdateArticle(article);

        try
        {
            _articleService.SaveArticle();
        }
        catch (DbUpdateConcurrencyException)
        {
            if (!ArticleExists(id))
            {
                return NotFound();
            }
            else
            {
                throw;
            }
        }

        return StatusCode(HttpStatusCode.NoContent);
    }

    // POST: api/Articles
    [ResponseType(typeof(Article))]
    public IHttpActionResult PostArticle(Article article)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        _articleService.CreateArticle(article);

        return CreatedAtRoute("DefaultApi", new { id = article.ID }, article);
    }

    // DELETE: api/Articles/5
    [ResponseType(typeof(Article))]
    public IHttpActionResult DeleteArticle(int id)
    {
        Article article = _articleService.GetArticle(id);
        if (article == null)
        {
            return NotFound();
        }

        _articleService.DeleteArticle(article);

        return Ok(article);
    }

    private bool ArticleExists(int id)
    {
        return _articleService.GetArticle(id) != null;
    }
}

Controllers/BlogsController.cs

public class BlogsController : ApiController
{
    private IBlogService _blogService;

    public BlogsController(IBlogService blogService)
    {
        _blogService = blogService;
    }

    // GET: api/Blogs
    public IEnumerable GetBlogs()
    {
        return _blogService.GetBlogs();
    }

    // GET: api/Blogs/5
    [ResponseType(typeof(Blog))]
    public IHttpActionResult GetBlog(int id)
    {
        Blog blog = _blogService.GetBlog(id);
        if (blog == null)
        {
            return NotFound();
        }

        return Ok(blog);
    }

    // PUT: api/Blogs/5
    [ResponseType(typeof(void))]
    public IHttpActionResult PutBlog(int id, Blog blog)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        if (id != blog.ID)
        {
            return BadRequest();
        }

        _blogService.UpdateBlog(blog);

        try
        {
            _blogService.SaveBlog();
        }
        catch (DbUpdateConcurrencyException)
        {
            if (!BlogExists(id))
            {
                return NotFound();
            }
            else
            {
                throw;
            }
        }

        return StatusCode(HttpStatusCode.NoContent);
    }

    // POST: api/Blogs
    [ResponseType(typeof(Blog))]
    public IHttpActionResult PostBlog(Blog blog)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        _blogService.CreateBlog(blog);

        return CreatedAtRoute("DefaultApi", new { id = blog.ID }, blog);
    }

    // DELETE: api/Blogs/5
    [ResponseType(typeof(Blog))]
    public IHttpActionResult DeleteBlog(int id)
    {
        Blog blog = _blogService.GetBlog(id);
        if (blog == null)
        {
            return NotFound();
        }

        _blogService.DeleteBlog(blog);

        return Ok(blog);
    }

    private bool BlogExists(int id)
    {
        return _blogService.GetBlog(id) != null;
    }
}

在有需要时添加下面的过滤器，它会反转Articles list的顺序：

Filters/ArticlesReversedFilter.cs

public class ArticlesReversedFilter : ActionFilterAttribute
{
    public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
    {
        var objectContent = actionExecutedContext.Response.Content as ObjectContent;
        if (objectContent != null)
        {
            List
 _articles = objectContent.Value as List
;
            if (_articles != null && _articles.Count > 0)
            {
                _articles.Reverse();
            }
        }
    }
}

当添加下面的媒体类型格式化器，可以返回一个用逗号分割来展示的文章列表：

MediaTypeFormatters/ArticleFormatter.cs

public class ArticleFormatter : BufferedMediaTypeFormatter
{
    public ArticleFormatter()
    {
        SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/article"));
    }

    public override bool CanReadType(Type type)
    {
        return false;
    }

    public override bool CanWriteType(Type type)
    {
        //for single article object
        if (type == typeof(Article))
            return true;
        else
        {
            // for multiple article objects
            Type _type = typeof(IEnumerable
);
            return _type.IsAssignableFrom(type);
        }
    }

    public override void WriteToStream(Type type,
                                        object value,
                                        Stream writeStream,
                                        HttpContent content)
    {
        using (StreamWriter writer = new StreamWriter(writeStream))
        {
            var articles = value as IEnumerable
;
            if (articles != null)
            {
                foreach (var article in articles)
                {
                    writer.Write(String.Format("[{0},\"{1}\",\"{2}\",\"{3}\",\"{4}\"]",
                                                article.ID,
                                                article.Title,
                                                article.Author,
                                                article.URL,
                                                article.Contents));
                }
            }
            else
            {
                var _article = value as Article;
                if (_article == null)
                {
                    throw new InvalidOperationException("Cannot serialize type");
                }
                writer.Write(String.Format("[{0},\"{1}\",\"{2}\",\"{3}\",\"{4}\"]",
                                                _article.ID,
                                                _article.Title,
                                                _article.Author,
                                                _article.URL,
                                                _article.Contents));
            }
        }
    }
}

添加下面两个 消息 处理器，第一个负责Response中添加定制 header，第二个可以决定这个请求是否被接受：

MessageHandler/HeaderAppenderHandler.cs

public class HeaderAppenderHandler : DelegatingHandler
{
    async protected override Task SendAsync(
            HttpRequestMessage request, CancellationToken cancellationToken)
    {
        HttpResponseMessage response = await base.SendAsync(request, cancellationToken);

        response.Headers.Add("X-WebAPI-Header", "Web API Unit testing in chsakell's blog.");
        return response;
    }
}

HeaderAppenderHandler/EndRequestHandler.cs

public class EndRequestHandler : DelegatingHandler
{
    async protected override Task SendAsync(
        HttpRequestMessage request, CancellationToken cancellationToken)
    {
        if (request.RequestUri.AbsoluteUri.Contains("test"))
        {
            var response = new HttpResponseMessage(HttpStatusCode.OK)
            {
                Content = new StringContent("Unit testing message handlers!")
            };

            var tsc = new TaskCompletionSource();
            tsc.SetResult(response);
            return await tsc.Task;
        }
        else
        {
            return await base.SendAsync(request, cancellationToken);
        }
    }
}

添加下面被用于从Web 应用程序中注册Controller 的 DefaultAssembliesResolver

CustomAssembliesResolver.cs

public class CustomAssembliesResolver : DefaultAssembliesResolver
{
    public override ICollection GetAssemblies()
    {
        var baseAssemblies = base.GetAssemblies().ToList();
        var assemblies = new List(baseAssemblies) { typeof(BlogsController).Assembly };
        baseAssemblies.AddRange(assemblies);

        return baseAssemblies.Distinct().ToList();
    }
}

Asp.NET Web Application

添加 UnitTestingWebAPI.API Web应用项目，并且添加引用 UnitTestingWebAPI.Core, UnitTestingWebAPI.Data 和 UnitTestingWebAPI.Service，同样需要安装下列组件包：

1. Entity Framework

2. Microsoft.AspNet.WebApi.WebHost

3. Microsoft.AspNet.WebApi.Core

4. Microsoft.AspNet.WebApi.Client

5. Microsoft.AspNet.WebApi.Owin

6. Microsoft.Owin.Host.SystemWeb

7. Microsoft.Owin

8. Autofac.WebApi2

在Global配置文件(如果没有就新增一个)中配置初始化数据库配置

Global.asax

protected void Application_Start()
{
    GlobalConfiguration.Configure(WebApiConfig.Register);

    // Init database
    System.Data.Entity.Database.SetInitializer(new BloggerInitializer());
}

同样要记得添加一个相关的Connection String在Web.config文件中.

注册外部Controller

在Web Application的根目录创建一个 Owin Startup.cs 文件并且粘贴下面的代码，在(autofac configration)需要的时候,这部分代码会确保 UnitTestingWebAPI.API.Core(CustomAssembliesResolver) 项目正确使用WebApi Controller和注入合适的仓库以及服务.

Startup.cs

public class Startup
{
    public void Configuration(IAppBuilder appBuilder)
    {
        var config = new HttpConfiguration();
        config.Services.Replace(typeof(IAssembliesResolver), new CustomAssembliesResolver());
        config.Formatters.Add(new ArticleFormatter());

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );


        // Autofac configuration
        var builder = new ContainerBuilder();
        builder.RegisterApiControllers(typeof(BlogsController).Assembly);
        builder.RegisterType().As().InstancePerRequest();
        builder.RegisterType().As().InstancePerRequest();

        //Repositories
        builder.RegisterAssemblyTypes(typeof(BlogRepository).Assembly)
            .Where(t => t.Name.EndsWith("Repository"))
            .AsImplementedInterfaces().InstancePerRequest();
        // Services
        builder.RegisterAssemblyTypes(typeof(ArticleService).Assembly)
            .Where(t => t.Name.EndsWith("Service"))
            .AsImplementedInterfaces().InstancePerRequest();

        IContainer container = builder.Build();
        config.DependencyResolver = new AutofacWebApiDependencyResolver(container);

        appBuilder.UseWebApi(config);
    }
}

在这个时候，你应该可以启动Web应用程序并且使用下面的请求来获取article或blogs（这里的端口可能不一致）：

http://localhost:57414/api/Articles

http://localhost:57414/api/Blogs
