试图从OData v3移动到OData v4。为什么我在尝试使用OData Functions时总是收到404?
Web API 配置:
ODataModelBuilder builder = new ODataConventionModelBuilder();
//etc
builder.EntitySet<LocalizableString>("LocalizableStringApi");
//etc
var getComparitiveTableFunction = builder.EntityType<LocalizableString>().Collection.Function("GetComparitiveTable");
getComparitiveTableFunction.Parameter<string>("cultureCode");
getComparitiveTableFunction.ReturnsCollection<ComparitiveLocalizableString>();
//etc
config.MapODataServiceRoute("OData_Kore_CMS", "odata/kore/cms", builder.GetEdmModel());
C#代码:
[EnableQuery(AllowedQueryOptions = AllowedQueryOptions.All)]
[HttpGet]
//[ODataRoute("Default.GetComparitiveTable(cultureCode={cultureCode})")] // Tried this, but gets errors and I noticed the function is in the OData model anyway without this, so should be fine.
public virtual IHttpActionResult GetComparitiveTable([FromODataUri] string cultureCode)
{
// Implementation
return Ok(query);
}
从 $metadata 返回的 XML:
<Schema Namespace="Default">
<Function Name="GetComparitiveTable" IsBound="true">
<Parameter Name="bindingParameter" Type="Collection(Kore.Localization.Domain.LocalizableString)"/>
<Parameter Name="cultureCode" Type="Edm.String" Unicode="false"/>
<ReturnType Type="Collection(Kore.Localization.Models.ComparitiveLocalizableString)"/>
</Function>
...
如您所见,它位于架构/OData 模型中......但以下查询不起作用:
http://localhost:30863/odata/kore/cms/LocalizableStringApi/Default.GetComparitiveTable(cultureCode='en-US')
我还尝试了以下方法:
http://localhost:30863/odata/kore/cms/LocalizableStringApi/GetComparitiveTable(cultureCode='en-US')
http://localhost:30863/odata/kore/cms/Default.GetComparitiveTable(cultureCode='en-US')
http://localhost:30863/odata/kore/cms/GetComparitiveTable(cultureCode='en-US')
以上所有结果都会导致404。
所以......我在这里做错了什么?
