[英]error using then and catch in angularjs
I am trying to create an user authentication using Flask as backend and AngularJS as frontend. 我正在尝试使用Flask作为后端和AngularJS作为前端来创建用户身份验证。 But I'm stuck at this error.
但是我被这个错误困住了。 Below is the Angular code that I am using.
以下是我正在使用的Angular代码。 The login function executes successfully but also throws the following error.
登录函数成功执行,但还会引发以下错误。 Please help me in solving/figuring this issue.
请帮助我解决/解决这个问题。
'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 () {
})
};
}]);
Error 错误

and my login function 和我的登录功能
function login(email, password) {
// create a new instance of deferred
var deferred = $q.defer();
// send a post request to the server
$http.get('http://' + email + ':' + password + '@localhost:5000/api/login')
// handle success
.success(function (data, status) {
if(status === 200 && data.result){
// print response
console.log('Response: ' + JSON.stringify(data))
user = true;
deferred.resolve();
} else {
// print response
console.log('Response: ' + JSON.stringify(data))
user = false;
deferred.reject();
}
})
// handle error
.error(function (data) {
// print response
console.log('Response: ' + JSON.stringify(data))
user = false;
deferred.reject();
});
// return promise object
return deferred.promise;
}
I am tired of searching and figuring this issue but didn't find anything. 我已经厌倦了寻找和解决这个问题,但没有找到任何东西。 Don't know what's wrong :/ Any help will be appreciated.
不知道怎么了:/任何帮助将不胜感激。
try this 尝试这个
userAuth.login($scope.email, $scope.password)
.then(function () {
console.log('I am in then function');
},
function(error){
console.log('Error', error);
})
