找不到方法：'System.Web.Http.ApiController.get_Request（）'

Question

我有一个Azure Web应用程序，在调用Web API Controller Post方法时，我遇到了以下异常：

Method not found: 'System.Net.Http.HttpRequestMessageSystem.Web.Http.ApiController.get_Request()'

在本地运行应用程序时，我无法重现此错误，它只发生在Azure上。

这是控制器的代码：

using System;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using TFL.BL;
using TFL.BO;
using TFL.Web.DTO;

namespace TFL.WebAPI.Controllers
{
    public class SearchController : ApiController
    {
        public HttpResponseMessage Get() 
        {
            return Request.CreateResponse(200);
        }
        // POST: api/Search
        public HttpResponseMessage Post([FromBody]SearchDTO dto)
        {
            Search s = new Search();
            s.FirstName = dto.FirstName;
            s.LastName = dto.LastName;
            s.Email = dto.Email;
            s.BirthDate = dto.BirthDate;
            s.City = dto.City;
            s.Country = dto.Country;
            s.FromAge = Convert.ToInt32(dto.FromAge);
            s.Gender = Convert.ToInt32(dto.Gender);
            s.ImagePath = dto.ImagePath;
            s.PageNumber = Convert.ToInt32(dto.PageNumber);
            s.PathUrl = dto.PathUrl;
            s.ProfessionID = Convert.ToInt32(dto.ProfessionID);

            s.State = dto.State;
            s.Str = dto.Str;
            s.Tags = null;
            s.ToAge = Convert.ToInt32(dto.ToAge);
            s.TypeID = Convert.ToInt32(dto.TypeID);
            s.Culture = dto.Culture;

            return Request.CreateResponse(HttpStatusCode.Accepted, SearchBL.GetList(s));
        }

        // PUT: api/Search/5
        public void Put(int id, [FromBody]string value)
        {
        }

        // DELETE: api/Search/5
        public void Delete(int id)
        {
        }
    }
}

Answer 1

我测试了你的代码，它在我的Azure Web App上运行良好。由于它在您的开发机器上运行良好，请检查以下选项以在发布之前删除其他文件。

Answer 2

我设法通过将我的Web API函数的返回类型更改为实际对象而不是HttpResponseMessages来解决此问题。奇迹般有效。

Answer 3

我最近遇到了类似的问题。我不得不改变

return ResponseMessage(Request.CreateResponse(HttpStatusCode.BadRequest, new Error(ModelState, 0)));

至

return BadRequest(ModelState);

我仍然不知道为什么以前的代码（在其他API项目中工作）在这里混乱，但这对我来说是修复。
