Web API:Odata路由始终返回404响应 [英] Web API: Odata route always returning a 404 response
问题描述
我是OData的新手.我已经建立了一个ASP.NET Web API控制器,如下所示:
I am new to OData. I have built an ASP.NET Web API controller as shown below:
using System.Data.Entity;
using System.Data.Entity.Infrastructure;
using System.Web.OData.Routing;
namespace HelloWebApi.Controllers
{
public class TestsController : ODataController
{
ProductsContext db = new ProductsContext();
private bool TestExists(int key)
{
return db.tests.Any(p => p.key== key);
}
protected override void Dispose(bool disposing)
{
db.Dispose();
base.Dispose(disposing);
}
[EnableQuery]
public IQueryable<test> Get()
{
return db.tests;
}
}
}
模型如下所示:
public class Test
{
[Key]
public int key { get; set; }
public string aaa { get; set; }
}
我还配置了RouteConfig
,ODdataConfig
和WebApiConfig
,如下所示:
I have also configured the RouteConfig
, ODdataConfig
, and WebApiConfig
as shown below:
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.Ignore("{resource}.axd/{*pathInfo}");
routes.MapHttpRoute(
name: "Default",
routeTemplate: "{controller}/{action}/{id}"
);
}
}
public class ODataConfig
{
public static void Register(HttpConfiguration config)
{
// Web API routes
config.MapHttpAttributeRoutes();
ODataModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<Test>("Tests");
config.MapODataServiceRoute("odata", "odata", builder.GetEdmModel());
}
}
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
以及global.asax
文件:
public class WebApiApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
GlobalConfiguration.Configure(config =>
{
ODataConfig.Register(config); //this has to be before WebApi
WebApiConfig.Register(config);
});
//FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
}
}
为了解决这个问题,我尝试了一些修改.但是我一直收到HTTP 404 Not Found响应.我还尝试将[ODataRoute]
属性显式添加到操作方法名称中.这样做时,我得到的是HTTP 406不可接受的响应.
I tried making a number of modifications in order to resolve this. But I am consistently getting an HTTP 404 Not Found response. I also tried explicitly adding an [ODataRoute]
attribute to the action method name; when doing that I instead get an HTTP 406 Not Acceptable response.
我要配置的URL是:
http://localhost:6701/odata/tests/
其中odata
是后缀,tests
是控制器名称.请指出我做错了.
Where odata
is the suffix and tests
is the controller name. Please point out what I am doing wrong.
推荐答案
The routes configured by the ODataConventionModelBuilder
are case-sensitive. In your code, you have defined:
builder.EntitySet<Test>("Tests");
基于此,端点将为 http://localhost:6701/odata/Tests/(请注意测试"中的大写字母"T").
Based on this, the endpoint will be http://localhost:6701/odata/Tests/ (note the upper-case "T" in "Tests").
这是设计使然,以保持与OData规范的兼容性.
This is by design, in order to maintain compatibility with the OData specification.
也就是说,截至 Web API OData 5.4 ,您可以选择使用HttpConfiguration
类的EnableCaseInsensitive()
方法启用不区分大小写的路由.例如,您可以在ODataConfig.Register()
方法中添加:
That said, as of Web API OData 5.4, you can optionally enable case-insensitive routes using the HttpConfiguration
class's EnableCaseInsensitive()
method. E.g., in your ODataConfig.Register()
method you could add:
config.EnableCaseInsensitive(caseInsensitive: true);
有关更多信息,请参见不区分大小写的基本支持在Microsoft的用于OData V4文档的ASP.NET Web API 下.
For more information, see Basic Case Insensitive Support under Microsoft's ASP.NET Web API for OData V4 Docs.
