This is my models class:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace Test.Models
{
public class User
{
public int Id { get; set; }
public string Name { get; set; }
//public DateTime startTime { get; set; }
//public DateTime endTime { get; set; }
//public int Age { get; set; }
//public string Adress { get; set; }
}
}
This is my controller class:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using Test.DBA;
using Test.Models;
namespace Test.Controllers
{
public class UserAPIController : ApiController
{
ApiDbContext dbContext = null;
public UserAPIController()
{
dbContext = new ApiDbContext();
}
[HttpPost]
public IHttpActionResult InsertUser(User user)
{
dbContext.Users.Add(user);
dbContext.SaveChangesAsync();
return Ok(user.Name);
}
public IEnumerable<User> GetAllUser()
{
var list = dbContext.Users.ToList();
return list;
}
[HttpPost]
public IHttpActionResult DeleteUser(User user)
{
dbContext.Users.Remove(user);
dbContext.SaveChanges();
return Ok(user.Name);
}
[HttpGet]
public IHttpActionResult ViewUser(int id)
{
var student = dbContext.Users.Find(id);
return Ok(student);
}
[HttpPost]
public IHttpActionResult UpdateUser(User user)
{
User std = dbContext.Users.Find(user.Id);
std.Name = user.Name;
//std.startTime = user.startTime;
//std.endTime = user.endTime;
//std.Age = user.Age;
//std.Adress = user.Adress;
dbContext.Entry(std).State = System.Data.Entity.EntityState.Modified;
dbContext.SaveChangesAsync();
return Ok();
}
}
}
I'm trying to call the post method with the google chrome app Postman. I call it with raw JSON body:
{
Id : 1,
Name : "Sample"
}
The get methods work, but when i debug post methods the parameters are always null.
Edit 1: Routing:
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
尝试使用[FromBody]
装饰参数:
public IHttpActionResult DeleteUser([FromBody]User user)
尝试将以下请求标头添加到邮递员:
