c# - Web API OData V4 在本地工作，但不在 IIS 上

问题描述

我有一个在 VS2017 上运行的 ASP .NET Web 应用程序（.Net Framework 4.6.1），它创建了一个 OData V4 服务，如此处所述（https://www.odata.org/blog/how-to-use-web-api -odata-to-build-an-odata-v4-service-without-entity-framework/）

从 VS 2017 IIS Express 运行时，Web API 在我的 localhost 服务器上正常运行。http://localhost:[portNumber]/ $metadata 返回正确的数据。 在此处输入图像描述

但是，当我通过 Project->Publish->File System 将同一个项目发布到 IIS 服务器时。成功发布后，如果我运行https://hostname/folderName/ $metadata. 它说找不到目录。在图片中，testCors/testOData 是我发布 Web API 项目的位置。

在此处输入图像描述

这是 IIS 中的文件夹结构在发布后的样子 在此处输入图像描述

这是我的 WebApiConfig.cs

 public static void Register(HttpConfiguration config)
        {
            config.MapODataServiceRoute("odata", null, GetEdmModel(), new DefaultODataBatchHandler(GlobalConfiguration.DefaultServer));
            config.EnsureInitialized();
        }
        private static IEdmModel GetEdmModel()
        {
            ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
            builder.Namespace = "Demos";
            builder.ContainerName = "DefaultContainer";
            builder.EntitySet<Person>("People");
            builder.EntitySet<Trip>("Trips");
            builder.EntitySet<Employee>("Employees");
            var edmModel = builder.GetEdmModel();
            return edmModel;
        }

这是我的 Web.Config

解决方案

问题在于我如何发布我的应用程序。我将它作为文件夹发布，而在 IIS 中我必须将其转换为网站/应用程序。

将其转换为应用程序后，它可以正常工作。
