Question

我使用以下代码调用控制器方法并传递参数。调用方法但控制器方法中的值为空。

相同的代码在MVC 4项目中运行良好，但在Asp.Net Core MVC中它无效。

var UserModel = {
  "FName": "Abc",
  "LName": "Pqr"
};
$.ajax({
  url: 'http://localhost:60600/Home/AddUser/',
  type: "POST",
  contentType: 'application/json; charset=utf-8',
  dataType: "json",
  data: JSON.stringify(UserModel),
  success: function () {
  }
});

public class HomeController : Controller
{
  // GET: /<controller>/
  public IActionResult Index()
  {
    return View();
  }

  // [HttpPost]
  // [AllowAnonymous]
  public IActionResult AddUser(UserModel model)
  {
    //  Add user model
    return Json("");
  }
}

public class UserModel
{
  public string FName { get; set; }
  public string LName { get; set; }
}

Answer 1

你可以这样试试

var UserModel =
{
    FName: "Abc",
    LName: "Pqr"
};
$.ajax({
    url: '/Home/AddUser/',
    type: "POST",
    //contentType: 'application/json; charset=utf-8',
    dataType: "json",
    data: UserModel,
    success: function () {

    }
});

Answer 2

请删除JSON.stringify

var UserModel = {
  "FName": "Abc",
  "LName": "Pqr"
};
$.ajax({
  url: 'http://localhost:60600/Home/AddUser/',
  type: "POST",
  contentType: 'application/json; charset=utf-8',
  dataType: "json",
  data: UserModel,
  success: function () {
  }
});

Jquery ajax没有将参数传递给Asp.Net Core MVC中的控制器方法
