【问题描述】：
我正在探索 OData。
我一直关注Referbruv的Working with OData - Integrating an Existing ASP.NET Core 3.x API！
我的 EdmModel 跟随他的，如下：
internal static IEdmModel GetEdmModel() {
// create OData builder instance
var builder = new ODataConventionModelBuilder();
// CLIENTS
// map the entities set which are the types returned from the endpoint onto the OData pipeline
// the string parameter is the name of the controller
// which supplies the data of type Client entity model in this case
builder.EntitySet<ClientIndexDto>("ODataClient").EntityType.HasKey(x => x.id);
builder.EntitySet<ClientDetailsDto>("ODataClientDetails").EntityType.HasKey(x => x.id);
// configure a function onto the builder, AllClients
// which is same as the name provided in the ODataRoute
builder.Function("AllClients")
.ReturnsCollectionFromEntitySet<ClientIndexDto>("ODataClient");
builder.Function("ClientById")
.ReturnsCollectionFromEntitySet<ClientDetailsDto>("ODataClientDetails")
.Parameter<int>("id");
return builder.GetEdmModel();
}
部分：
builder.Function("ClientById")
.ReturnsCollectionFromEntitySet<ClientDetailsDto>("ODataClientDetails")
.Parameter<int>("id");
处理通过 Id 获取客户。
为了完整起见，我在我的 StartUp.cs 文件中为 OData 提供了以下内容：
app.UseEndpoints(endpoints => {
endpoints.MapControllers();
endpoints.Select().Filter().OrderBy().Expand().Count().MaxTop(10);
endpoints.MapODataRoute("odata", "odata", GetEdmModel());
});
返回的$元数据如下：

我的控制器如下：
using JobsLedger.API.Controllers.API.App.Interfaces;
using JobsLedger.API.ControllerServices.API.App.ClientService.Interfaces;
using JobsLedger.DATA;
using JobsLedger.DATA.Repositories.Interfaces;
using JobsLedger.MODELS.API.App.Client;
using Microsoft.AspNet.OData;
using Microsoft.AspNet.OData.Routing;
using Microsoft.AspNetCore.Mvc;
using System;
using System.Threading.Tasks;
using AutoMapper;
using Microsoft.AspNetCore.Authorization;
namespace JobsLedger.API.Controllers.API.App {
[Route("api/[controller]")]
[ApiController]
[Authorize(Roles = "TenantAdmin,Admin,Employee")]
public class ODataClientController : ODataController, IClientController {
private readonly IClientServices _clientServices;
public ODataClientController( IClientServices clientServices) {
_clientServices = clientServices;
}
[HttpGet]
[EnableQuery()]
[ODataRoute("AllClients()")]
public IActionResult Get()
{
return Ok(_clientServices.GetAllClientsAsDto());
}
[HttpGet]
[EnableQuery]
[ODataRoute("ClientById(id={id})")]
public IActionResult Get(int id) {
return Ok(_clientServices.GetClient(id));
}
我想获取一个 ID 为“5”的客户端，所以我在 Postman 中使用了以下 get 命令：
https://localhost:44301/odata/ClientById(id=5)?
正如教程所示 - “id=5”周围有括号
它到达端点，但 id 设置为“0”。
鉴于我的 EdmModel、#MetaData 和单个 Id 的控制器操作，为什么当我发送带有 (Id=5) 的 GET 命令时，我得到 Id=0？我需要做什么来解决这个问题？
