小编use*_*602的帖子

我正在尝试运行我的测试，但是我收到“对象引用未设置为对象的实例”。有什么想法吗？我正在使用起订量。

测试方法：

     // Arrange
    Mock<ICustomerRepository> CustomerRepo = new Mock<ICustomerRepository>();
    Customer NewCustomer = new Customert() { ID = 123456789, Date = DateTime.Now };
    CustomerRepo.Setup(x => x.Add()).Returns(NewCustomer);
    var Controller = new CustomerController(CustomerRepo.Object, new Mock<IProductRepository>().Object);

    // Act
    IHttpActionResult actionResult = Controller.CreateCustomer();

创建客户方法：

     Customer NewCustomer = CustomerRepository.Add();

      //ERROR OCCURS BELOW  
     return Created(Request.RequestUri + "/" + NewCustomer.ID.ToString(), new { customerID = NewCustomer.ID });

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,"日期":"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 });
}
