在現有的ASP.NET MVC 5項目中使用WebAPI 2.2

我在現有的MVC 5項目中使用帶有屬性路由的WebAPI 2.2。我打算將整個網站遷移到WebAPI，但這需要一些時間。我有一切工作，但我擔心我可能做錯了什麼。在現有的ASP.NET MVC 5項目中使用WebAPI 2.2

This SO post seems to suggest I should be calling GlobalConfiguration.Configure(WebApiConfig.Register) in the Global.asax.cs file。

如果我簡單地去除通常以WebApiConfig.Register()提供的HttpConfiguration參數，並簡單地將WebApiConfig.Register()方法中調用GlobalConfiguration.Configure(x => x.MapHttpAttributeRoutes()) - 所述的WebAPI端點與所期望的結果作出響應。

原來這就是我結束了：

public class MvcApplication : System.Web.HttpApplication 
{ 
    protected void Application_Start() 
    { 
     AreaRegistration.RegisterAllAreas(); 
     WebApiConfig.Register(); 
     FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); 
     RouteConfig.RegisterRoutes(RouteTable.Routes); 
     BundleConfig.RegisterBundles(BundleTable.Bundles); 
    } 
} 


class WebApiConfig 
{ 
    public static void Register() 
    { 
     GlobalConfiguration.Configure(x => x.MapHttpAttributeRoutes()); 
    } 
}

有什麼不對這種方法？

事實證明，只有兩種方法可以解決將WebAPI 2.2添加到現有項目時出現的配置問題。當我閱讀代碼時，我正在做兩個修補程序，這些修補程序都變得很清楚。

以下：

public class MvcApplication : System.Web.HttpApplication 
{ 
    protected void Application_Start() 
    { 
     AreaRegistration.RegisterAllAreas(); 
     WebApiConfig.Register(); 
     FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); 
     RouteConfig.RegisterRoutes(RouteTable.Routes); 
     BundleConfig.RegisterBundles(BundleTable.Bundles); 
    } 
} 


class WebApiConfig 
{ 
    public static void Register() 
    { 
     GlobalConfiguration.Configure(x => x.MapHttpAttributeRoutes()); 
    } 
}

幾乎是一樣執行以下操作：

public class MvcApplication : System.Web.HttpApplication 
{ 
    protected void Application_Start() 
    { 
     AreaRegistration.RegisterAllAreas(); 
     //WebApiConfig.Register(); 
     GlobalConfiguration.Configure(WebApiConfig.Register); 
     FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); 
     RouteConfig.RegisterRoutes(RouteTable.Routes); 
     BundleConfig.RegisterBundles(BundleTable.Bundles); 
    } 
} 

class WebApiConfig 
{ 
    public static void Register(HttpConfiguration configuration) 
    { 
     configuration.MapHttpAttributeRoutes(); 
    } 
}

看來我只是經歷一個心理時隔:)

這應該是很明顯那GlobalConfiguration.Configure(x => x.MapHttpAttributeRoutes())基本上和GlobalConfiguration.Configure(WebApiConfig.Register)一樣。

從邏輯上說，它們應該產生相同的結果。以下是System.Web.Http名稱空間中GlobalConfiguration的Microsoft代碼：

/// <summary> 
/// Provides a global <see cref="T:System.Web.Http.HttpConfiguration"/> for ASP.NET applications. 
/// </summary> 
public static class GlobalConfiguration 
{ 
    private static Lazy<HttpConfiguration> _configuration = CreateConfiguration(); 

    ///... code excluded for brevity 

    /// <summary> 
    /// Gets the global <see cref="T:System.Web.Http.HttpConfiguration"/>. 
    /// </summary> 
    public static HttpConfiguration Configuration 
    { 
     get { return _configuration.Value; } 
    } 

    /// <summary> 
    /// Performs configuration for <see cref="GlobalConfiguration.Configuration"/> and ensures that it is 
    /// initialized. 
    /// </summary> 
    /// <param name="configurationCallback">The callback that will perform the configuration.</param> 
    public static void Configure(Action<HttpConfiguration> configurationCallback) 
    { 
     if (configurationCallback == null) 
     { 
      throw new ArgumentNullException("configurationCallback"); 
     } 

     configurationCallback.Invoke(Configuration); 
     Configuration.EnsureInitialized(); 
    } 

    private static Lazy<HttpConfiguration> CreateConfiguration() 
    { 
     return new Lazy<HttpConfiguration>(() => 
     { 
      HttpConfiguration config = new HttpConfiguration(new HostedHttpRouteCollection(RouteTable.Routes)); 
      ServicesContainer services = config.Services; 
      Contract.Assert(services != null); 
      services.Replace(typeof(IAssembliesResolver), new WebHostAssembliesResolver()); 
      services.Replace(typeof(IHttpControllerTypeResolver), new WebHostHttpControllerTypeResolver()); 
      services.Replace(typeof(IHostBufferPolicySelector), new WebHostBufferPolicySelector()); 
      services.Replace(typeof(IExceptionHandler), 
       new WebHostExceptionHandler(services.GetExceptionHandler())); 
      return config; 
     }); 
    } 

    ///... code excluded for brevity 
}
