如何將JSON數據從ASP.NET MVC 5發送回客戶端Angular（即在身份驗證期間）

Question

如果經過身份驗證，我必須重定向到其他視圖，並且我需要發送包含AngularJS使用的用戶名和用戶名的JSON數據。

Redirect有效，但是我不確定如何將經過身份驗證的用戶信息作為JSON數據發送到客戶端。

有人能幫我嗎？

這是我在MVC方面擁有的一些代碼...

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Security;
using TVS.Core.Interfaces;
using TVS.Domain;
using TVS.UI.Models;

namespace TVS.UI.Controllers
{
    public class homeController : Controller
    {


        private readonly IUser _IUser;




        public homeController(IUser IUser)
        {

            _IUser = IUser;

        }




        public ActionResult RedirectAngular()
        {
            return View();
        }
        [HttpGet]

        public ActionResult Login()
        {
            return View();
        }
        [HttpPost]

        public ActionResult Login(UserModel model)
        {

            if (ModelState.IsValid)
            {

                    if (_IUser.IsValidUser(model.Login,model.Password))
                    {

                         FormsAuthentication.SetAuthCookie(model.Login, false);


                        return RedirectToAction("RedirectAngular", "home");


                    }
                    else
                    {
                       // ModelState.AddModelError("", "The user name or password provided is incorrect.");
                    }
                //}
            }



            return View();

        }

        public ActionResult LogOff()
        {
            FormsAuthentication.SignOut();

            return RedirectToAction("Login", "home");
        }


    }
}

如果登錄表單實際上是頁面，而您在身份驗證后重定向到的任何頁面都是另一個頁面，則可以將其放在模型或ViewBag中並呈現視圖。 然后，只需使用模型/ ViewBag來填充頁面/應用設置javascript全局或將它們按如下所示推入角度值或常數即可：

//Controller Action
public ActionResult Logon(string username, string password) {
    //authentication successful...
    //using ViewBag, but model will do as well..
    ViewBag.UserId = 12; //for example...
    ViewBag.UserName = "John Doe";

    return View();
}

@* View
   somewhere near end of <body> tag...
*@

<script src=".../angular.js">
<script>
//or load this from a file...
  angular.module('moduleName', []);
</script>

<script>
  //this need to be in page!!
  angular.moduel('moduleName')
    .value('appSettings', {
        userId : @ViewBag.UserId,
        userName: '@ViewBag.UserName'
    });
</script>

<script>
   //this can be loaded from file...
   angular.controller('controllerName', ctrlFn);
   ctrlFn.$inject = ['$log', 'appSettings'];
   function ctrlFn($log, appSettings) {
      //do something with appSetting here...
      $log.info(appSettings.userId, appSettings.userName);
   }
</script>

如果這不是您的意思，並且您將表單信息作為Ajax推送，而Angular實際上是SPA，則需要使用AJAX在服務器和客戶端之間封送數據。

像這樣返回JsonResult ...

[HttpPost]
public ActionResult Logon(string username, string password) 
{
    //authenticate here... assume succesful...
    var user = new { userId = 12, userName = "John Doe" }
    return Json(user, "application/json", Encoding.UTF8);
}

以您的角度，只需處理返回的所有內容，如下所示：

<script>
   angular.module('moduleName')
      .factory('loginSvc', svcFn);
   svcFn.$inject = ['$http'];
   function svcFn($http) {
       var svc = { 
          login: login
       };

       return svc;

       function login(username, password) {
          return $http.post(
              '/api/login',
              angular.toJson({username: username, password: password});
       }
   }

   angular.module('moduleName')
        .controller('controllerName', ctrlFn);
   ctrlFn.$inject = ['$log', 'loginSvc'];
   function ctrlFn($log, loginSvc) {
      var self = this;
      self.username = "";
      self.password = "";
      self.login = login;

      function login() {
           loginSvc.login(username, password)
               .then(handleLoginSuccess)
               .catch(handleLoginFailure);
      }

      function handleLoginSuccess(userInfo) {
          $log.info(userInfo); //this should contain logged in user id and username
      }

      //some other functions here...
   }
</script>
