Angularjs promises. Controller + service doesn't work - javascript

I just want to use load bar in my app. I got service in angularjs like this
app.service('gethostsbyip', [ '$http', '$q', function($http, $q){
this.gethostsbyip = function(hostname, username, password){
var deffered = $q.defer();
var result = $http.post(REST_API_IP + 'discover?ip=' + hostname + '&username=' + username + '&password=' + password).then(function(resp){
deffered.resolve(result);
location.href="#createvirtualization";
toastr.success('Your hosts, templates, networks have been updated!', 'Data was loaded!');
}).catch(function(e){
toastr.error('Some data in your form is incorrect. Please, try again!', 'Error!');
});
return deffered.promise;
};
}]);
And in the angular controller, I need to change flag into false value after my service (gethostsbyip.gethostsbyip) is done.
When the function runs without errors the flag changes, but I need to change the flag in case of an error in the service.
app.controller('discoverCtrl', ['$scope', '$q', function($scope, $q) {
$scope.submitButt = function(hostname, username, password){
if(!hostname || !username || !password){
}
else {
$scope.flag = true;
gethostsbyip.gethostsbyip(hostname, username, password).then(function(res){
$scope.test = false;
})
.catch(function(e){
$scope.test = false;
})
}
};
}

then event accepts two parameter.
app.controller('discoverCtrl', ['$scope', '$q', function($scope, $q) {
$scope.submitButt = function(hostname, username, password){
if(!hostname || !username || !password){
}
else {
$scope.flag = true;
gethostsbyip.gethostsbyip(hostname, username, password)
.then(
// you currently have one callback in your `then` method
function(res){
$scope.test = false;
}
// solution
, function(resForErrorCase){
$scope.test = false;
})
.catch(function(e){
$scope.test = false;
})
}
};
Promise definition reference

Reject the promise if error occurs
.catch(function(e) {
deffered.reject(e);
toastr.error('Some data in your form is incorrect. Please, try again!', 'Error!');
});

angularjs app to redirect after login

Currently, when the users logs in, the login page does't redirect to the homepage.
'use strict';
angular.module('myapp').service('auth', function auth($http, API_URL, authToken, $state, $window, $q) {
function authSuccessful(res) {
authToken.setToken(res.token);
$state.go('main');
}
this.login = function (email, password) {
return $http.post(API_URL + 'login', {
email: email,
password: password
}).success(authSuccessful);
}
this.register = function (email, password) {
return $http.post(API_URL + 'register', {
email: email,
password: password
}).success(authSuccessful);
}
However, I have set my $state.go to redirect to main. Where is the problem? why is it not redirecting?
annex
here is my login.js controller, how it looks:
angular.module('myapp').controller('LoginCtrl', function ($scope, alert, auth, $auth) {
$scope.submit = function () {
$auth.login({
email: $scope.email,
password: $scope.password
})
.then(function(res) {
var message = 'Thanks for coming back ' + res.data.user.email + '!';
if (!res.data.user.active)
message = 'Just a reminder, please activate your account soon :)';
alert('success', 'Welcome', message);
})
.catch(handleError);
}
// i forgot to include this error handler in my code:
function handleError(err) {
alert('warning', 'oops there is a problem!', err.message);
}
});
Since this is an async action, angular doesn't know when the action finishes and thus when to update the $scope. For this to work you'll need to manually call $scope.apply(), but since you don't have access to the $scope in your service, you need to move the redirection logic (i.e. $state.go('main')) inside a controller, and call it like this:
angular.module('myapp').controller('LoginCtrl', function($scope, auth, $state) {
function redirect(res) {
$state.go('main');
// manually update the scope
$scope.$apply();
}
auth.login(email, password)
.success(redirect);
});
EDIT: Integrate with the given controller
angular.module('myapp').controller('LoginCtrl', function ($scope, alert, auth, $auth) {
$scope.submit = function () {
$auth.login({
email: $scope.email,
password: $scope.password
})
.then(function(res) {
var message = 'Thanks for coming back ' + res.data.user.email + '!';
if (!res.data.user.active) {
message = 'Just a reminder, please activate your account soon :)';
}
alert('success', 'Welcome', message);
return null;
})
.then(function() {
$state.go('main');
// manually update the scope
$scope.$apply();
})
// google replacement of the above commented out code bit
.catch(handleError);
}
});
EDIT 2: Use $timeout instead of $scope.$apply so you don't get $digest error.
angular.module('myapp').controller('LoginCtrl', function ($scope, alert, auth, $auth, $timeout) {
...
.then(function() {
// $timeout calls $scope.$apply() by default,
// but it does it in a safely manner - never throws a '$digest already in progress' exception
$timeout(function() {
$state.go('main');
});
})
...

How refresh token works and how last failed http request called again which gave 401...?

I am working with a OAuth2 using angularjs. Now i got stuck in authentication with OAuth in which i am unable to resend last 401 api. Any Idea.
I am using this oauth2 repo.
Controller.js
app.controller('validate', ['$scope', '$rootScope', '$location', 'fullname', '$http', '$timeout', '$cookies', 'OAuth', function ($scope, $rootScope, $location, fullname, $http, $timeout, $cookies, OAuth) {
OAuth.getAccessToken($scope.user).then( function successCallBack(response){
$scope.response = response;
if($scope.response.status == 200){
console.log($scope.response.data);
$scope.accessToken = $scope.response.data.access_token;
$scope.refreshToken = $scope.response.data.refresh_token;
localStorage.setItem("accessToken", $scope.accessToken);
localStorage.setItem("refreshToken", $scope.refreshToken);
var userId = response.headers('userid');
console.log(userId);
$cookies.put("userId", userId);
window.location.href = 'user_profile.php';
}
}, function errorCallBack(response){
console.log(response);
});
}]);
app.js
app.config(['OAuthProvider', function(OAuthProvider) {
OAuthProvider.configure({
baseUrl: 'http://testzone.xxxxxx.net/api/LoginTest/Login/web/',
clientId: '123456789',
clientSecret: 'otszh9nonaosok88gsswc8k4w8ww04s',
grantPath: 'api/oauth2/token',
revokePath: 'api/oauth2/revoke'
});
}]);
app.run(['$rootScope', '$window', 'OAuth', '$cookies', '$timeout', function($rootScope, $window, OAuth, $cookies, $timeout) {
$rootScope.$on('oauth:error', function(event, rejection) {
// Ignore `invalid_grant` error - should be catched on `LoginController`.
if ('invalid_token' === rejection.data.error || 'invalid_grant' === rejection.data.error || 'invalid_request' === rejection.data.error || 'invalid_client' === rejection.data.error || 'unauthorized_client' === rejection.data.error || 'unsupported_grant_type' === rejection.data.error) {
$cookies.remove('userId');
$timeout(function(){
window.location.href = 'index.php';
},200);
}
// Refresh token when a `invalid_token` error occurs.
if ('expired_token' === rejection.data.error) {
console.log(rejection);
OAuth.getRefreshToken();
}
console.log(rejection);
console.log(rejection.data.error);
console.log(rejection.data.error_description);
// Redirect to `/login` with the `error_reason`.
//return $window.location.href = 'index.php';
});
}]);
Thanks
You can do something like this when analysing the error response:
if (rejection.status === 401) {
var authService = $injector.get('oAuthService');
var authData = ipCookie(oAuthConstants.oAuthCookieName);
var $http = $http || $injector.get('$http');
var deferred = $q.defer();
if (authData) {
authService.refreshToken().then(function () {
//this repeats the request with the original parameters
return deferred.resolve($http(rejection.config));
});
}
return deferred.promise;
}
else if (rejection.status === 403) {
var toaster = $injector.get('toaster');
toaster.pop('error', "Access Denied", "You are not authorized to do this request.");
}
else {
return $q.reject(rejection);
}
The key to repeat the last 401 api call is:
return deferred.resolve($http(rejection.config));
I hope it helps.
A refresh token is a special kind of JWT that is used to obtain a renewed id_token at any time.
Refresh tokens carry the information necessary to get a new access token. In other words, whenever an access token is required to access a specific resource, a client may use a refresh token to get a new access token issued by the authentication server.

it will guide you how to do it.

ngMock complains unexpected request when request is expected

My ng app is working fine, but I am trying to write a ngMock test for my controller; I am basically following along the example on angular's website: https://docs.angularjs.org/api/ngMock/service/$httpBackend
The problem I am running into is that it complains about unexpected request even when request is being expected.
PhantomJS 1.9.8 (Windows 8 0.0.0) NotificationsController should fetch notification list FAILED
Error: Unexpected request: GET Not valid for testsapi/AspNetController/AspNetAction
Expected GET api/AspNetController/AspNetAction
What I do not get is that, on the error line, why is there a "tests" word appended before my service url?
I thought it should be sending to 'api/AspNetController/AspNetAction'
What am I doing wrong here. I can't find any one else running into the same problem as me through google.
Edit: I noticed that, if i remove the sendRequest portion from my controller, and have the unit test log my request object in console, i see the following json.
{
"method":"GET",
"url":"Not valid for testsapi/AspNetController/AspNetAction",
"headers":{
"Content-Type":"application/json"
}
}
here is the controller code
angular.module('MainModule')
.controller('NotificationsController', ['$scope', '$location', '$timeout', 'dataService',
function ($scope, $location, $timeout, dataService) {
//createRequest returns a request object
var fetchNotificationsRequest = dataService.createRequest('GET', 'api/AspNetController/AspNetAction', null);
//sendRequest sends the request object using $http
var fetchNotificationsPromise = dataService.sendRequest(fetchNotificationsRequest);
fetchNotificationsPromise.then(function (data) {
//do something with data.
}, function (error) {
alert("Unable to fetch notifications.");
});
}]
);
Test code
describe('NotificationsController', function () {
beforeEach(module('MainModule'));
beforeEach(module('DataModule')); //for data service
var $httpBackend, $scope, $location, $timeout, dataService;
beforeEach(inject(function ($injector) {
$httpBackend = $injector.get('$httpBackend');
$scope = $injector.get('$rootScope');
$location = $injector.get('$location');
$timeout = $injector.get('$timeout');
dataService = $injector.get('dataService');
var $controller = $injector.get('$controller');
createController = function () {
return $controller('NotificationsController', {
'$scope': $scope,
'$location': $location,
'$timeout': $timeout,
'dataService': dataService,
});
};
}));
afterEach(function () {
$httpBackend.verifyNoOutstandingExpectation();
$httpBackend.verifyNoOutstandingRequest();
});
it('should fetch notification list', function () {
$httpBackend.expectGET('api/AspNetController/AspNetAction'); //this is where things go wrong
var controller = createController();
$httpBackend.flush();
});
});
Data service code
service.createRequest = function(method, service, data) {
var req = {
method: method, //GET or POST
url: someInjectedConstant.baseUrl + service,
headers: {
'Content-Type': 'application/json'
}
}
if (data != null) {
req.data = data;
}
return req;
}
service.sendRequest = function (req) {
return $q(function (resolve, reject) {
$http(req).then(function successCallback(response) {
console.info("Incoming response: " + req.url);
console.info("Status: " + response.status);
console.info(JSON.stringify(response));
if (response.status >= 200 && response.status < 300) {
resolve(response.data);
} else {
reject(response);
}
}, function failCallback(response) {
console.info("Incoming response: " + req.url);
console.info("Error Status: " + response.status);
console.info(JSON.stringify(response));
reject(response);
});
});
}
ANSWER:
since dataService created the finalized webapi url by someInjectedConstant.baseUrl + whatever_relative_url passed in from controller, In the test that I am writting, I will have to inject someInjectedConstant and
$httpBackend.expectGET(someInjectedConstant.baseUrl + relativeUrl)
instead of just doing a $httpBackend.expectGET(relativeUrl)
Clearly Not valid for tests is getting prepended to your url somewhere in your code. It's also not adding the hardcoded domain (see note below). Check through all your code and any other parts of the test pipeline that might be adding this to the url.
A couple of points on your code:
avoid hardcoding domain names in your code (I see you've fixed this in your updated answer)
maybe someInjectedConstant could be more explicitly named
there is no need for you to wrap $http with $q, so service.sendRequest can be:
service.sendRequest = function (req) {
$http(req).then(function (response) { // no need to name the function unless you want to call another function with all success/error code in defined elsewhere
console.info("Incoming response: " + req.url);
console.info("Status: " + response.status);
console.info(JSON.stringify(response));
return response.data; // angular treats only 2xx codes as success
}, function(error) {
console.info("Incoming response: " + req.url);
console.info("Error Status: " + response.status);
console.info(JSON.stringify(response));
});
}

Not setting additional header parameter in angularjs XHR request without mannual refresh

I am trying to send extra header in XHR request (init with $resource).Following is my config
var app = angular.module('app',['angularMoment']).
run(function ($rootScope,$location,$route, $timeout, $http) {
var token = localStorage.getItem("userToken");
$http.defaults.headers.common.token = token;
}
I am changing hash params (eg. after login process) to navigate in app. So when I am sending any XHR request after login process (wihout mannual reload), it's sending token (request header) as NULL. But when I reload my page manually it's working fine (i.e sending token as header). Also I tried with $route.reload() but it's not working.
Please suggest how can I get rid of this issue.
Thanks
EDIT :
After trying with follwing code :
app.factory('tokenInterceptorService', ['$q', '$location', function ($q, $location) {
var tokenInterceptor = {};
var request = function (config) {
config.headers = config.headers || {};
var token = localStorage.getItem("userToken");
config.headers.token = token;
return config;
}
// if response errors with 401 redirect to lgoin
var response = function (rejection) {
if (rejection.status === 401) {
$location.path('/');
}
return $q.reject(rejection);
}
tokenInterceptor.request = request;
tokenInterceptor.response = response;
return tokenInterceptor;
}]);
app.config(function ($httpProvider) {
$httpProvider.interceptors.push('tokenInterceptorService');
});
app.run(function ($rootScope, $location,$route, $timeout, $http) {
$rootScope.config = {};
$rootScope.config.app_url = $location.url();
$rootScope.config.app_path = $location.path();
$rootScope.layout = {};
$rootScope.layout.loading = false;
$rootScope.$on('$routeChangeStart', function () {
//need to validate
console.log($rootScope.isValidated + "app");
//show loading
$timeout(function(){
$rootScope.layout.loading = true;
});
});
$rootScope.$on('$routeChangeSuccess', function () {
//hide loading
$timeout(function(){
$rootScope.layout.loading = false;
}, 200);
});
$rootScope.$on('$routeChangeError', function () {
alert('Something went wrong. Please refresh.');
$rootScope.layout.loading = false;
});
})
It stop rendring the views in application with ".run" and trapping in $rootScope.$on('$routeChangeError', and giving the error Error: [$rootScope:inprog] $digest already in progress.
Since if I understand correctly your user token is always taken from localstorage, you can setup a watch on that localStorage key in your run function (Demo plunker for working with Localstorage in angular: http://plnkr.co/edit/7hP13JAjPybxkRuMZLZ0?p=preview )
angular.module('app',[]).run(['$rootScope', '$http', function($root, $http) {
$root.$watch(function() {
return localStorage.getItem('userToken');
}, function(userToken) {
$http.defaults.headers.common.token = userToken;
});
});
This should solve your problems without any interceptors etc.
However I'd actually recommend using http interceptor as calls to localStorage are slow, or setting the defaults where you actually set the user token after login or logout (save it also on a scope variable, and initialize it in the run part like you do now).
You need to set up an interceptor that alters every request sent to the server. You can find out more form the docs here, but essentially you need to set up a factory service on your app to add the token header like so:
app.factory('tokenInterceptorService', ['$q', '$location', 'localStorage', function ($q, $location, localStorage) {
var tokenInterceptor = {};
var request = function (config) {
config.headers = config.headers || {};
var token = localStorage.getItem("userToken");
if (token) {
config.headers.token = token;
}
return config;
}
// if response errors with 401 redirect to lgoin
var response = function (rejection) {
if (rejection.status === 401) {
$location.path('/login');
}
return $q.reject(rejection);
}
tokenInterceptor.request = request;
tokenInterceptor.response = response;
return tokenInterceptor;
}]);
and then register it during the config stage with:
app.config(function ($httpProvider) {
$httpProvider.interceptors.push('tokenInterceptorService');
});
module.run executes well before anything else in the app (but after module.config). Would the localStorage have been set by then? I think that is happening later, which is why you see this value after reloading the page.
An interceptor would be the way to go.
How are you setting the value in localStorage?

angular service not work as singleton

Angular doc states:
Angular services are singletons
I want to use the angular service as singleton, so I can access the logged-in user data every where in my application. but the serivce does not seem to return the same data, here is my codes.
Service:
angular.module("myapp", [])
.service("identity", function (){
this.token = null;
this.user = null;
});
Facotry:
.factory("authentication", function (identity, config, $http, $cookieStore) {
var authentication = {};
authentication.login = function (email, password, remember) {
var p=$http.post(config.baseUrl+"api/","email="+email+"&password="+password);
return p.then(function (response) {
identity= response.data;
if (remember) {
$cookieStore.put("identity", identity);
}
});
};
authentication.isAuthenticated = function () {
if (!identity.token) {
//try the cookie
identity = $cookieStore.get("identity") || {};
}
console.log(identity) // {token: 23832943, user: {name: something}}
return !!identity.token;
};
return authentication;
});
controller:
.controller('LoginCtrl', function ($state, $scope, authentication, identity) {
var user = $scope.user = {};
$scope.login = function () {
authentication.login(user.email, user.password, user.remember)
.then(function () {
if (authentication.isAuthenticated()) {
console.log(identity); // {token:null, user: null}
$state.transitionTo("dashboard");
}
});
};
});
The identity is injected to both authentication and controller. But the first console logs the correct user data, while the second console just logs the same data as initially defined. If the service is singleton as stated, I would expect two identity returns the same data. What am I doing wrong here?. any pointers are appreciated.
In your authentication service change
identity= response.data;
to
identity.token=response.data.token;
identity.user=response.data.user;
and things should work.
Basically what you are doing is replacing the identity object reference.
