我试图用Ihttpstatus标头获取此
JSON响应,该标头声明代码201并保持IHttpActionResult作为我的方法返回类型.
我想要的JSON返回：
{“CustomerID”: 324}
我的方法：
[Route("api/createcustomer")]
[HttpPost]
[ResponseType(typeof(Customer))]
public IHttpActionResult CreateCustomer()
{
Customer NewCustomer = CustomerRepository.Add();
return CreatedAtRoute<Customer>("DefaultApi",new controller="customercontroller",CustomerID = NewCustomer.ID },NewCustomer);
}
JSON返回：
“ID”: 324,
“Date”: “2014-06-18T17:35:07.8095813-07:00”,
以下是我尝试过的一些回报,或者给了我uri null错误,或者给了我类似于上面例子的回复.
return Created<Customer>(Request.RequestUri + NewCustomer.ID.ToString(),NewCustomer.ID.ToString());
return CreatedAtRoute<Customer>("DefaultApi",new { CustomerID = NewCustomer.ID },NewCustomer);
使用httpresponsemessage类型方法,可以解决此问题,如下所示.但是我想使用IHttpActionResult：
public HttpResponseMessage CreateCustomer()
{
Customer NewCustomer = CustomerRepository.Add();
return Request.CreateResponse(HttpStatusCode.Created,new { CustomerID = NewCustomer.ID });
}
解决方法
这会得到你的结果：
[Route("api/createcustomer")]
[HttpPost]
//[ResponseType(typeof(Customer))]
public IHttpActionResult CreateCustomer()
{
...
string location = Request.RequestUri + "/" + NewCustomer.ID.ToString();
return Created(location,new { CustomerId = NewCustomer.ID });
}
现在ResponseType不匹配.如果需要此属性,则需要创建新的返回类型,而不是使用匿名类型.
public class CreatedCustomerResponse
{
public int CustomerId { get; set; }
}
[Route("api/createcustomer")]
[HttpPost]
[ResponseType(typeof(CreatedCustomerResponse))]
public IHttpActionResult CreateCustomer()
{
...
string location = Request.RequestUri + "/" + NewCustomer.ID.ToString();
return Created(location,new CreatedCustomerResponse { CustomerId = NewCustomer.ID });
}
另一种方法是使用Customer类上的DataContractAttribute来控制序列化.
[DataContract(Name="Customer")]
public class Customer
{
[DataMember(Name="CustomerId")]
public int ID { get; set; }
// DataMember omitted
public DateTime? Date { get; set; }
}
然后只返回创建的模型
return Created(location,NewCustomer);
// or
return CreatedAtRoute<Customer>("DefaultApi",NewCustomer);
