AngularJS - 狀態碼爲302的HTTP GET請求

Question

我使用AngularJS構建了一個RESTful API，並且我被卡住了。我正在嘗試發送一個GET請求，該請求將給我一個User給定的username。下面是代碼：

var loginModule = angular.module('login-module', []); 


    loginModule 
     .factory('loginService',['$http','$rootScope', function($http){ 

      var factoryMethods = {}; 
      factoryMethods.login = function(username){ 
       return $http.get('http://localhost:8080/WebProjekat/webapi/users/'+username); 
      } 
      factoryMethods.setLoggedUser = function(user){ 
       $rootScope.loggedUser = user; 
      } 
      return factoryMethods; 
     }]) 
     .controller('loginController', ['$scope', '$http','loginService', function ($scope, $http, loginService){ 
       $scope.username = ''; 
       $scope.password = ''; 

       $scope.user = {}; 

       $scope.userLogin = function(){ 
        loginService.login($scope.username) 
          .then(function(response){ 

           console.log("User :" +angular.toJson(response.data)+"successfully logged in!"); 
           $scope.user = response.data; 
           loginService.setLoggedUser($scope.user); 

          },function(error){ 

           console.log("Error occured durring user authentication!"); 

          }); 
       } 

     }]); 

出於某種原因，這個函數產生的承諾：

factoryMethods.login = function(username){ 
        return $http.get('http://localhost:8080/WebProjekat/webapi/users/'+username); 
       } 

被拒絕，而狀態代碼我得到的是302我不明白的是爲什麼沒有重定向發生，爲什麼數據映射到第二個回調函數，當promise被拒絕時被調用。

我遵循執行流程，Jersey Servlet成功找到UserResource類以及它需要調用的服務，以便使用給定的用戶名來獲取用戶。這裏是Java代碼：

/** 
    * URL: http://localhost:8030/WebProjekat/webapi/users/{userId} 
    * @param username - identification of some user that is registered on the system 
    * @param uriInfo - variable which can manipulate URL 
    * @return user with the given username 
    * @throws JsonParseException 
    * @throws JsonMappingException 
    * @throws IOException 
    */ 
    @GET 
    @Produces(MediaType.APPLICATION_JSON) 
    @Path("/{userId}") 
    public Response getUserById(@PathParam("userId") String username, @Context UriInfo uriInfo) throws JsonParseException, JsonMappingException, IOException { 
     User user = new User(); 

     List<User> listOfUsers = userService.getAllUsers(); 
     if((user = userService.getUser(username, listOfUsers))!=null) { 


      user.addLink(getUserSectionsUri(uriInfo, user), "sections"); 
      user.addLink(getSelfUri(uriInfo, user), "self"); 

      return Response.status(Status.FOUND) 
          .entity(user) 
          .build(); 
     } 

     return Response.status(Status.NOT_FOUND) 
         .build(); 
    } 

任何形式的幫助將不勝感激！

您應該返回Status.OK（200）而不是Status.FOUND（302）在servlet中
