簡単な質問です。ここに私のコントローラは、次のとおりです。"メソッドが見つかりません: 'System.Net.Http.HttpRequestMessage System.Web.Http.ApiController.get_Request()'。"
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using Milos_MovieStore.DAL;
using Milos_MovieStore.Models;
using Milos_MovieStore.DTO;
using System.Data.Entity;
namespace Milos_MovieStore.Controllers.Api
{
public class CustomersController : ApiController
{
private DBContext_MovieStore _dbcontext;
public CustomersController()
{
_dbcontext = new DBContext_MovieStore();
}
protected override void Dispose(bool disposing)
{
_dbcontext.Dispose();
}
// GET /api/customers
[HttpGet]
public IHttpActionResult GetCustomers()
{
List<Customer> customers = _dbcontext.Customers.Include(c => c.MembershipType).ToList();
return Ok(CustomersToDTOList(customers));
}
// GET /api/customers/1
[HttpGet]
public IHttpActionResult GetCustomer(int id)
{
Customer customer = _dbcontext.Customers.Include(c => c.MembershipType).SingleOrDefault(c => c.Id == id);
if (customer == null)
return NotFound();
return Ok(CustomerToDTO(customer));
}
//POST /api/customers
[HttpPost]
public IHttpActionResult CreateCustomer(CustomerDTO customerDTO)
{
if (!ModelState.IsValid)
return BadRequest();
_dbcontext.Customers.Add(DTOToCustomer(customerDTO));
_dbcontext.SaveChanges();
return Created(new Uri(Request.RequestUri + "/" + customerDTO.Id), customerDTO);
}

}
// DELETE /api/customer/1
[HttpDelete]
public IHttpActionResult DeleteCustomer(int id)

return Ok(id);
}
private CustomerDTO CustomerToDTO(Customer customer)
{
CustomerDTO customerDTO = new CustomerDTO();
customerDTO.Id = customer.Id;
customerDTO.Name = customer.Name;
customerDTO.DOB = customer.DOB;
customerDTO.MembershipTypeId = customer.MembershipTypeId;
customerDTO.IsSubscribedToNewsletter = customer.IsSubscribedToNewsletter;
return customerDTO;
}
private Customer DTOToCustomer(CustomerDTO customerDTO)
{
Customer customer = new Customer();
customer.Id = customerDTO.Id;
customer.Name = customerDTO.Name;
customer.DOB = customerDTO.DOB;
customer.MembershipTypeId = customerDTO.MembershipTypeId;
customer.IsSubscribedToNewsletter = customerDTO.IsSubscribedToNewsletter;
return customer;
}
private void MapDTOToCustomer(CustomerDTO customerDTO, Customer customer)
{
customer.Id = customerDTO.Id;
customer.Name = customerDTO.Name;
customer.DOB = customerDTO.DOB;
customer.MembershipTypeId = customerDTO.MembershipTypeId;
customer.IsSubscribedToNewsletter = customerDTO.IsSubscribedToNewsletter;
}
private IEnumerable<CustomerDTO> CustomersToDTOList(IEnumerable<Customer> customers)
{
List<CustomerDTO> customersDTO = new List<CustomerDTO>();
foreach (Customer c in customers)
{
customersDTO.Add(CustomerToDTO(c));
}
return customersDTO;
}
}
}
...ここに私のDTOです:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
namespace Milos_MovieStore.DTO
{
public class CustomerDTO
{
public int Id { get; set; }
[Required]
[StringLength(255)]
public string Name { get; set; }
public DateTime? DOB { get; set; }
public byte MembershipTypeId { get; set; }
public bool IsSubscribedToNewsletter { get; set; }
}
}
...と、ここに私のPOSTリクエストです:
...などスクリーンショットでは、APIコントローラのJSONからPOSTメソッドでDTOを送信しています。私は解決策を見つけることができません。 DELETE要求とGET要求は問題なく動作しています。それは訓練プロジェクトですので、私がコントローラーに入れた奇妙な一時マッピングの方法については心配しないでください。
(新しいウリ( Request.RequestUri + "/" + customerDTO.Id)、customerDTO); ? Created()メソッドとは何ですか? – toha
... 200 OKの代わりに201 "作成された" HTTPレスポンスを作成するためのSystem.Web.Httpの仮想メソッドです。引数のUriは文字列f.e.:"/api/customers "... – cembo
