Question

我使用的是ASP.NET Core和AngularJS（不是AngularJS 2）。我按照这个链接AngularJS Tutorial for Login with MVC但我的mvc控制器（AuthenticateUser）获取空值。虽然我通过我的脚本获得了这个价值 JSON：密码：＆＃34;测试＆＃34; 用户名：＆＃34;测试＆＃34;

来源： {＆＃34;用户名＆＃34;：＆＃34;测试＆＃34;＆＃34;密码＆＃34;：＆＃34;测试＆＃34;}

虽然我追加了[FromBody]，但控制器（AuthenticateUser）仍然是空值。

这是我的代码： Service.js

＆＃13;

app.service("myAppService", function ($http) {

    this.UserLogin = function (User) {
        var response = $http({
            method: "post",
            url: "../Administrator/AuthenticateUser",
            data: JSON.stringify(User),
            dataType: "json"
        });
        return response;
    }

});

＆＃13;

Controller.js

＆＃13;

app.controller("MyAppController", function ($scope, MyAppService) {

    $scope.LoginCheck = function () {
        var User = {
            UserName: $scope.usrName,
            Password: $scope.usrPassword
        };

        var getData = MyAppService.UserLogin(User);
        getData.then(function (d) {
            alert(d.UserName);
            
        });
        debugger;
    }

});

＆＃13;

Index.cshtml

＆＃13;

<div class="container">
    <div id="loginbox" style="margin-top:50px;" class="mainbox col-md-6 col-md-offset-3 col-sm-8 col-sm-offset-2">

                            <button type="button" class="btn btn-success" ng-click="LoginCheck();">Login</button>

                </form>

</div>

AdministratorController.cs

public class AdministratorController : Controller

        // GET: /<controller>/
        public IActionResult Index()
        {
            return View();
        }

        [HttpPost]
        public JsonResult AuthenticateUser(UserAccessViewModel _users)
        //public string AuthenticateUser(UserAccessViewModel userAccess)
        {
            //string msg = string.Empty;

            //if (userAccess.UserName == null || userAccess.UserPassword == null)
            //    return "Please fill-out all entries";
            //else
            //{
                var users = _context.UserAccess.Where(w => w.Username.Equals(_users.UserName) &&
                                                   w.Userpassword.Equals(_users.UserPassword));
            //     if (users != null)
            //         return "Thanks for logging.";
            //     else
            //         return "Invalid username or password.";

            //}
            return Json(users);
        } 
    }
