无法从 Web api OK() 响应中提取模型对象

Question

我有模型class

 public class Employee
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Designation { get; set; }
        public string Department { get; set; }
        public DateTime Dateofjoin { get; set; }
        public string Phone { get; set; }
        public string Address { get; set; }
        public int IsActive { get; set; }
        public int row_number { get; set; }

    }

另一个模型 class 使用 'Employee' 模型 class 作为列表

  public class EmployeeList
    {
        public IList<Employee> Emp_List { get; set; }
        public int Return_Param { get; set; }
    }

我正在调用 api 方法来获取员工记录以及 return 参数。

  public IHttpActionResult Get_Employee()
        {
            if (!ModelState.IsValid)
                throw new HttpResponseException(HttpStatusCode.BadRequest);
            var displaydata = db.Get_Employee();
            return Ok(displaydata);
        }

这里显示'EmployeeList'模型class的数据returns对象，成功得到Emp_List和Return_Param。我有另一个控制器，从那里调用 api 方法并从 OK 方法 returned.

中提取响应

     public ActionResult Get_Employee()
        {
            EmployeeList empobj = new EmployeeList();
            try
            {

                empobj.Emp_List = new List<Employee>();
                HttpClient hc = new HttpClient();
                hc.BaseAddress = new Uri(baseURL);
                var consumeapi = hc.GetAsync("EmployeeApi");
                consumeapi.Wait();
                var readdata = consumeapi.Result;
                if (readdata.IsSuccessStatusCode)
                {
                    empobj.Emp_List = readdata.Content.ReadAsAsync<List<Employee>>().Result;
                    empobj.Return_Param = Convert.ToInt32(readdata.Content.ReadAsStringAsync());

                }             
            }
            catch (WebException ex)
            {
                if (ex.Status == WebExceptionStatus.Timeout) { }
                else throw;
            }
            return View("EmployeeList",empobj);
        }

但我无法提取模型对象，而是获取无法反序列化为 json 的异常。我怎么能得到 empobj.Emp_List 和 empobj.Return_Param if(readdata.IsSuccessStatusCode)?

Answer 1

var consumeapi = hc.GetAsync("EmployeeApi"); 调用了您的 Get_Employee() api 方法，对吗？我认为您的代码需要

if (readdata.IsSuccessStatusCode)
{
    empobj = readdata.Content.ReadAsAsync<EmployeeList>().Result;
}
