我尝试在System.Web.OData.ODataController 2中使用WebAPI。
WebConfig.cs
ODataModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<User>("User");
config.MapODataServiceRoute(
routeName: "ODataRoute",
routePrefix: null,
model: builder.GetEdmModel());控制器:
public class UserApiODataController : ODataController
{
[Route("api/lookups/users")]
[EnableQuery(AllowedQueryOptions = AllowedQueryOptions.All)]
public IHttpActionResult GetUsers()
{
try
{
var context = new DbContenxt();
return Ok(context.Users.AsQueryable());
}
catch (Exception exception)
{
return InternalServerError(exception);
}
}
}当我尝试查询数据时,我会得到错误:
GET http://localhost:58786/api/lookups/users 406 (Not Acceptable)当我用ODataController代替ApiController查询时,效果很好。

怎么了?有什么想法吗?

首先,在名称空间System.Web.OData.ODataController,中,我认为您正在使用Web V4库。application/atomsvc+xml不接受V4,因为只有"Json“是OData V4规范中的标准。
其次,odata=fullmetadata是OData V3元数据头,对于V4,它应该是odata.metadata=full。
第三,[Route("api/lookups/users")]是Web属性。如果您想使用ODataController,请使用OData版本。[ODataRoute("...")]
第四,请确保路线(.)中的路线模板。遵循OData Uri约定。请参阅更详细的这里
第五,您可以从这里获得更多的教程。
希望它能帮到你。谢谢。
