http请求在.net core 2.1中不包含createresponse的定义

Question

创建控制器并继承ApiController时，我使用的是.net core 2.1。但是在我的控制器方法中，返回类型HttpResponseMessage并给定错误，给出问题标题，这是我的方法

[HttpGet]
[Route("GetAll")]
[AcceptVerbs("Get", "Post")]
public HttpResponseMessage SelectCAllCustomers()
{
    try
    {
        return Request.CreateResponse<List<Customer>>(HttpStatusCode.OK, customerDetailsRepository.FindAll("SelectAllCustomers").ToList());
    }
    catch (Exception ex)
    {
        return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, ex);
    }
}

Answer 1

Asp.Net Core不再使用该API。

使用更新的语法

[Route("api/[controller]")]
public class CustomersController: Controller {

    //...

    [HttpGet("GetAll")]
    [AcceptVerbs("Get", "Post")]
    public IActionResult SelectCAllCustomers() {
        var model = customerDetailsRepository.FindAll("SelectAllCustomers").ToList();
        return Ok(model);            
    }
}
