“找不到方法:'System.Net.Http.HttpRequestMessage System.Web.Http.ApiController.get_Request()'." [英] "Method not found: 'System.Net.Http.HttpRequestMessage System.Web.Http.ApiController.get_Request()'."
问题描述
简短问题.这是我的控制器:
short question. Here is my controller:
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);
}
// PUT /api/customer/1
[HttpPut]
public IHttpActionResult UpdateCustomer(CustomerDTO customerDTO)
{
if (!ModelState.IsValid)
return BadRequest();
Customer customerInDB = _dbcontext.Customers.SingleOrDefault(c => c.Id == customerDTO.Id);
if (customerInDB == null)
return NotFound();
MapDTOToCustomer(customerDTO, customerInDB);
_dbcontext.SaveChanges();
return Ok(customerDTO);
}
// DELETE /api/customer/1
[HttpDelete]
public IHttpActionResult DeleteCustomer(int id)
{
if (!ModelState.IsValid)
return BadRequest();
Customer customerInDB = _dbcontext.Customers.SingleOrDefault(c => c.Id == id);
if (customerInDB == null)
return NotFound();
_dbcontext.Customers.Remove(customerInDB);
_dbcontext.SaveChanges();
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;
}
}
}
...这是我的DTO:
... here is my DTO:
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; }
}
}
...这是我的POST请求:
... and here is my POST request:
...如屏幕截图所示，我正在将JSON中的DTO发送到API控制器中的POST方法.我只是找不到解决方案. DELETE和GET请求正常工作.这是一个培训项目，所以不用担心我在控制器中使用的那些奇怪的临时映射方法...
... as you can see on the screenshot I'm sending DTO in JSON to POST method in API controller. I just can't find solution. DELETE and GET requests are working with no problem. It is a training project so don't worry about those weird temporary mapping methods I have put in controller ...
推荐答案
我找到了解决方案.
我开始构建后，有构建警告会转到输出窗口，但不会显示在主错误/警告窗口中.
after I starting building there was build warnings going to the output window but not showing in the main error / warning window.
检查您的输出/错误窗口是否有错误或警告，然后尝试解决..
check your output/error window if there are errors or warning then try to solve it..
他们与程序集冲突有关，并建议将程序集重定向放入 web.Config .
They were to do with assembly conflicts and said recommend putting the assembly redirect in the web.Config.
一旦我仔细阅读了所有内容，现在一切正常.
Once I had went through them all it now works.
例如:
<dependentAssembly>
<assemblyIdentity name="System.Net.Http" culture="neutral" publicKeyToken="b03f5f7f11d50a3a" />
<bindingRedirect oldVersion="0.0.0.0-4.2.0.0" newVersion="4.2.0.0" />
</dependentAssembly>
您可以尝试的其他方法是: 使您的方法像
other thing you can try is : make your method like
public IHttpActionResult CreateCustomer([FromBody]CustomerDTO customerDTO){}
看看是否有帮助.
