Question

嗨，我有一个使用Umbraco的Umbraco项目和1个Web api项目。我已经在第二个UmbracoCms.Core上安装了一个控制器，该控制器是UmbracoAppiController

 public class TestController : UmbracoApiController
    {

        [HttpGet]
        public IEnumerable<string> GetAll()
        {
            return new string[] { "value1", "value2" };
        }
}

我有global.asax.cs：

public class Global : System.Web.HttpApplication
    {
        void Application_Start(object sender, EventArgs e)
        {
            // Code that runs on application startup
            AreaRegistration.RegisterAllAreas();
            GlobalConfiguration.Configure(WebApiConfig.Register);
            RouteConfig.RegisterRoutes(RouteTable.Routes);            
        }
    }

和WebApiConfig.cs：

public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {

            config.MapHttpAttributeRoutes();

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

当我尝试进行网络api调用时，我得到：

Server Error in '/' Application.

Object reference not set to an instance of an object.  Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Answer 1

您根本不需要执行Global.asax.cs或WebApiConfig.cs文件-如果您继承自UmbracoApiController或{{1}，则路由将由Umbraco自动处理}。

请阅读our.umbraco.com上的“路由”文档，尤其是有关WebApi的部分：

基于此，您通往TestController的路线将如下所示：

SurfaceController

GlobalConfiguration.Configure（WebApiConfig.Register）和umbraco的问题
