我已经注册了批处理的WebAPI和的WebAPI服务如下如下批请求支持
Employee类
public class Employee
{
public int EmployeeID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public Employee()
{
}
public Employee(int id, string LN, string FN)
{
this.EmployeeID = id;
this.LastName = LN;
this.FirstName = FN;
}
}
员工接口
interface IEmployeeRepository
{
IEnumerable<Employee> GetAll();
Employee Get(int EmployeeID);
Employee Add(Employee emp);
void Remove(int EmployeeID);
bool Update(Employee emp);
}
雇员资源库
public class EmployeeRepository : IEmployeeRepository
{
private List<Employee> emp = new List<Employee>();
public EmployeeRepository()
{
emp.Add(new Employee(1, "Davolio", "Nancy"));
emp.Add(new Employee(2, "Fuller", "Andrew"));
emp.Add(new Employee(3, "Leverling", "Janet"));
emp.Add(new Employee(4, "Peacock", "Margaret"));
emp.Add(new Employee(5, "Buchanan", "Steven"));
}
public IEnumerable<Employee> GetAll()
{
return emp;
}
public Employee Get(int id)
{
return emp.Find(p => p.EmployeeID == id);
}
public Employee Add(Employee eObj)
{
if (eObj == null)
{
throw new ArgumentNullException("eObj");
}
emp.Add(eObj);
return eObj;
}
public void Remove(int id)
{
emp.RemoveAll(p => p.EmployeeID == id);
}
public bool Update(Employee eObj)
{
if (eObj == null)
{
throw new ArgumentNullException("eObj");
}
int index = emp.FindIndex(p => p.EmployeeID == eObj.EmployeeID);
if (index == -1)
{
return false;
}
emp.RemoveAt(index);
emp.Add(eObj);
return true;
}
}
的WebAPI控制器
public class EmployeeController : ApiController
{
static readonly IEmployeeRepository repository = new EmployeeRepository();
// GET api/<controller>
[HttpGet]
public object Get()
{
var queryString = HttpContext.Current.Request.QueryString;
var data = repository.GetAll().ToList();
return new { Items = data, Count = data.Count() };
}
public Employee GetEmployee(int id)
{
Employee emp = repository.Get(id);
if (emp == null)
{
throw new HttpResponseException(HttpStatusCode.NotFound);
}
return emp;
}
// POST api/<controller>
public HttpResponseMessage PostEmployee(Employee emp)
{
emp = repository.Add(emp);
var response = Request.CreateResponse<Employee>(HttpStatusCode.Created, emp);
string uri = Url.Link("Employee", new { id = emp.EmployeeID });
response.Headers.Location = new Uri(uri);
return response;
}
[HttpPut]
// PUT api/<controller>
public void PutEmployee(Employee emp)
{
if (!repository.Update(emp))
{
throw new HttpResponseException(HttpStatusCode.NotFound);
}
}
[HttpDelete]
public void Delete(int id)
{
// int empID = int32
Employee emp = repository.Get(id);
if (emp == null)
{
throw new HttpResponseException(HttpStatusCode.NotFound);
}
repository.Remove(id);
}
}
我提出来自客户端的AJAX请求，以便访问服务如下 我已经设置在AJAX的数据字段中的批处理请求

和整个Ajax请求

加薪的请求后，我得到了一个异常消息

1. ExceptionMessage:"No MediaTypeFormatter is available to read an object of type 'Employee' from content with media type 'multipart/mixed'."
