Question

我正在使用AngularJS构建一个RESTful API，但我遇到了困难。我正在尝试发送GET请求，该请求会在给定User的情况下向我提取username。这是代码：

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!");

                            });
                }

        }]);

由于某种原因，这个函数产生了许诺：

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

被拒绝，我得到的状态代码是302.我不明白为什么重定向发生，为什么数据映射到第二个回调函数，当promise被拒绝时调用。

我遵循执行流程，Jersey Servlet成功找到了UserResource类以及需要调用的服务，以便使用给定的用户名获取用户。这是Java代码：

/**
     * 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();
    }

任何形式的帮助将不胜感激！

你应该在servlet中返回Status.OK（200）而不是Status.FOUND（302）

AngularJS - 状态码为302
