后复杂类型答案

【问题描述】：

在 ASP.NET WebAPI 中潜水，我正在向服务器发送 HTTP Post/Put，但没有返回任何值，看起来 WebApi 无法识别提供的值。

为什么我不能得到返回的值？我错过了什么？

我有这个“复杂”的课程：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using CoreAPI.DB.Tables;

namespace CoreAPI.Controllers.RequestObjects
{
    public class CompanyBuildingObject
    {
        public int Id;
        public int Company_Id;
        public int Building_Id;
        public int[] BuildingUnit_Id;

        public CompanyBuildingObject()
        {
        }
     }
}

这是控制器：

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Data.Entity.Infrastructure;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using System.Web.Http.Description;
using CoreAPI.DB.Tables;
using CoreAPI.Controllers.RequestObjects;

namespace CoreAPI.Controllers
{
    public class CompanyBuildingsController : ApiController
    {
        private ApplicationDatabase db = new ApplicationDatabase();
    }

    [HttpPut]
    [Route("api/CompanyBuildings/PutSyncCompanyBuildingUnits/{id}")]
    [ResponseType(typeof(CompanyBuildingObject))]
    public IHttpActionResult PutSynCompanyBuildingUnits(int id, CompanyBuildingObject companyBuildingObject)
    {
        return Ok(companyBuildingObject);
    }

    [HttpPost]
    [Route("api/CompanyBuildings/PostSyncCompanyBuildingUnits/{id}")]
    [ResponseType(typeof(CompanyBuildingObject))]
    public IHttpActionResult PostSynCompanyBuildingUnits(int id, CompanyBuildingObject companyBuildingObject)
    {
        return Ok(companyBuildingObject);
    }
}

这是邮递员测试

【问题讨论】：

试试(int id, [FromBody] CompanyBuildingObject companyBuildingObject)
感谢@SlavaUtesinov，但它不起作用。

【解决方案1】：

如果您通过 Json 发送发布。您的格式应如下所示。

{
    "id": 3634,
    "CompanyBuildingObject":{
        "Id":1,
        "Company_Id":2,
         "Building_Id":2,
         "BuildingUnit_Id":[1,2,3,4]
    }
}

尝试使用POST Man 或任何客户端将数据发布到您的 API。

用json 格式代替form-urlencoded 尝试“RAW”

【讨论】：

感谢您的支持，但是发送请求的核心类没有使用json原始参数，我之前用PostMan测试过，效果很好。我找到了另一种可行的方法，请查看下面的答案。非常感谢。

【解决方案2】：

我已经测试了访问以读取/写入私有字段的属性的实现。现在正在工作，这是当前的课程。

public class CompanyBuildingObject
{
    private int _CompanyId = 0;
    private int _BuildingId = 0;
    private int _BuildingUnitId = 0;

    public int Company_Id
    {
        get { return _CompanyId; }
        set { _CompanyId = value; }
    }

    public int Building_Id
    {
        get { return _BuildingId; }
        set { _BuildingId = value; }
    }

    public int BuildingUnit_Id
    {
        get { return _BuildingUnitId; }
        set { _BuildingUnitId = value; }
    }

    public CompanyBuildingObject()
    {
        Company_Id = 0;
        Building_Id = 0;
        BuildingUnit_Id = 0;
    }
}


    [HttpPut]
    [ResponseType(typeof(CompanyBuildingUnit))]
    [Route("api/CompanyBuildingUnits/PutCompanyBuildingUnit/{id}")]
    public IHttpActionResult PutCompanyBuildingUnit(int id, CompanyBuildingObject cbo)
    {
        return Ok(SyncCompanyBuildingUnits(id, cbo));
    }

    [HttpPost]
    [ResponseType(typeof(CompanyBuildingUnit))]
    [Route("api/CompanyBuildingUnits/PostCompanyBuildingUnit/")]
    public IHttpActionResult PostCompanyBuildingUnit(CompanyBuildingObject cbo)
    {
        return Ok(SyncCompanyBuildingUnits(0, cbo));
    }
