Web API OData V4 在本地工作，但不在 IIS 上

【中文标题】Web API OData V4 在本地工作，但不在 IIS 上

【英文标题】：Web API OData V4 works locally but not on IIS

【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 服务器上运行正常。 http://localhost:[portNumber]/$metadata 返回正确的数据。

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。它是说找不到目录。在图片中，testCors/testOData 是我发布 Web API 项目的位置。

这是 IIS 中的文件夹结构在发布后的样子

这里是我的 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

【问题讨论】：

你是如何发表这篇文章的？我们通常进行文件系统部署：docs.microsoft.com/en-us/visualstudio/deployment/…

@JakeSteffen 我使用了相同的文件系统方法，并添加了通过文件系统发布后的图片

【参考方案1】：

问题在于我如何发布我的应用程序。我将其发布为文件夹，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。
