如何对Web API添加到现有的ASP.NET MVC 4 Web应用程序项目?
我想一个的ASP.NET Web API 添加到ASP.NET MVC 4 Web应用程序项目,在开发Visual Studio的2012年。我必须执行哪些步骤,以一个正常运作的Web API添加到项目中?我知道,我需要一个控制器从ApiController派生,但是这就是所有我知道了。
I wish to add an ASP.NET Web API to an ASP.NET MVC 4 Web Application project, developed in Visual Studio 2012. Which steps must I perform to add a functioning Web API to the project? I'm aware that I need a controller deriving from ApiController, but that's about all I know.
让我知道如果我需要提供更多的细节。
Let me know if I need to provide more details.
我需要执行的步骤是:
- 添加引用
System.Web.Http.WebHost
。 - 添加
App_Start \\ WebApiConfig.cs
(见下文code段)。 - 导入命名空间
System.Web.Http
在的Global.asax.cs
。 - 呼叫
WebApiConfig.Register(GlobalConfiguration.Configuration)
在MvcApplication.Application_Start()
(在文件的Global.asax.cs
)的前的注册默认Web应用程序的路由,否则将采取precedence。 - 添加控制器从
System.Web.Http.ApiController
导出。
- Add reference to
System.Web.Http.WebHost
. - Add
App_Start\WebApiConfig.cs
(see code snippet below). - Import namespace
System.Web.Http
inGlobal.asax.cs
. - Call
WebApiConfig.Register(GlobalConfiguration.Configuration)
inMvcApplication.Application_Start()
(in fileGlobal.asax.cs
), before registering the default Web Application route as that would otherwise take precedence. - Add a controller deriving from
System.Web.Http.ApiController
.
然后我可以从the教程(你的第一个的ASP.NET Web API)来定义我的API控制器。
I could then learn enough from the tutorial (Your First ASP.NET Web API) to define my API controller.
App_Start \\ WebApiConfig.cs:
App_Start\WebApiConfig.cs:
using System.Web.Http;
class WebApiConfig
{
public static void Register(HttpConfiguration configuration)
{
configuration.Routes.MapHttpRoute("API Default", "api/{controller}/{id}",
new { id = RouteParameter.Optional });
}
}
的Global.asax.cs:
Global.asax.cs:
using System.Web.Http;
...
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
WebApiConfig.Register(GlobalConfiguration.Configuration);
RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}

有传言,该包的NuGet Microsoft.AspNet.WebApi必须安装上述工作。
Word has it, the NuGet package Microsoft.AspNet.WebApi must be installed for the above to work.
