使用then錯誤並捕獲angularjs

Question

我正在嘗試使用Flask作為后端和AngularJS作為前端來創建用戶身份驗證。 但是我被這個錯誤困住了。 以下是我正在使用的Angular代碼。 登錄函數成功執行，但還會引發以下錯誤。 請幫助我解決/解決這個問題。

'use strict';

var userModule = angular.module('userModule', ['userServices']);

userModule.controller('LoginController', ['$scope', '$location', 'userAuth', function($scope, $location, userAuth) {

$scope.login = function() {
    console.log("username: " + $scope.email + ", password: " + $scope.password);
    // userAuth.login($scope.username, $scope.password);

    // initial values
  $scope.error = false;
  $scope.disabled = true;

  // call login from service
  userAuth.login($scope.email, $scope.password)
  // handle success
  .then(function () {
    console.log('I am in then function');
  })
  .catch(function () {

  })
};

}]);

錯誤

TypeError: userAuth.login(...).then(...).catch is not a function

和我的登錄功能

function login(email, password) {

// create a new instance of deferred
var deferred = $q.defer();

// send a post request to the server
$http.get('http://' + email + ':' + password + '@localhost:5000/api/login')
  // handle success
  .success(function (data, status) {
    if(status === 200 && data.result){

      // print response
      console.log('Response: ' + JSON.stringify(data))

      user = true;
      deferred.resolve();
    } else {

      // print response
      console.log('Response: ' + JSON.stringify(data))

      user = false;
      deferred.reject();
    }
  })
  // handle error
  .error(function (data) {

    // print response
    console.log('Response: ' + JSON.stringify(data))

    user = false;
    deferred.reject();
  });

// return promise object
return deferred.promise;

  }

我已經厭倦了尋找和解決這個問題，但沒有找到任何東西。 不知道怎么了：/任何幫助將不勝感激。

嘗試這個

userAuth.login($scope.email, $scope.password)
 .then(function () {
    console.log('I am in then function');
 },
 function(error){
    console.log('Error', error);
 })
