The following code gives me an error every time it is run. The part service.getTracks(req, function(tracks), gives an error on the parameter 'req' saying it is undefined. However, the program still works, it works but still gives an error. I was wondering if anyone could shed some light upon why this happens? I've been staring blindly for 4 hours now, with 0 progress... And help at all is appreciated!
Please ask questions regarding the issue if anything is blurry or something.
Best regards,
Victor

The only place you're actually using req is here:
$http(req).then(
function(res) {
(...etc...)
then() will run after $http even if req is undefined, which is why your code's still working, so you don't need req defined anywhere - but since you're not defining it before using it in $http, you're getting the error.

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) {
$http(req).then(function (response) { // no need to name the function unless you want to call another function with all success/error code in defined elsewhere
console.info("Incoming response: " + req.url);
console.info("Status: " + response.status);
console.info(JSON.stringify(response));
return response.data; // angular treats only 2xx codes as success
}, function(error) {
console.info("Incoming response: " + req.url);
console.info("Error Status: " + response.status);
console.info(JSON.stringify(response));
});
}
This is my code for initializing the app and creating a controller.
var app = angular.module('newstalk',[]);
app.controller("articleCtrl",['$scope','$http','dataService',function($scope,$http,dataService){
$scope.articles = dataService.getArticles();
$scope.commentForm = function(id,userid){
console.log(userid);
var uid = userid;
var c = this.contents;
var data = {
content: c,
user: uid
};
console.log(data);
$http.post('/api/article/'+id,data);
};
}]);
Now, I have also created a service to fetch the data from the server. Here is the code for that:
(function(){
angular.module('newstalk')
.factory('dataService',dataService);
function dataService(){
return {
getArticles : getArticles
};
function getAricles(){
console.log("yolo");
return $http({
method:get,
url:'/api/articles/0'
})
.then(sendResponse);
}
function sendResponse(response){
console.log(data);
return response.data;
}
}
})
This is in a seperate file. Now when I run this I get a Error: $injector:unpr Unknown Provider error.
I've read multiple other such questions, none of which came to help. Any ideas?
I think you have not used IIFE correctly.
you should put () at the end of file.
(function(){
angular.module('newstalk')
.factory('dataService',dataService);
function dataService(){
return {
getArticles : getArticles
};
function getAricles(){
console.log("yolo");
return $http({
method:get,
url:'/api/articles/0'
})
.then(sendResponse);
}
function sendResponse(response){
console.log(data);
return response.data;
}
}
})()
putting () execute/run the function. rightnow you are not executing IIFE.

When I load page in browser I get the error :
Uncaught Error: [$injector:unpr]
http://errors.angularjs.org/1.2.17/$injector/unpr?p0=AuthenticationProvider%20%3C-%20Authentication
Please can somebody help me to solve this error.
Looks like you are using two angular.module inside you application authApp & DashboardApp, then you should have make available your service to DashboardApp module by inject authApp into it.
var app = angular.module("DashboardApp", ["authApp"]);
Assuming authApp should be intialize somewhere like this angular.module('authApp',[])
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 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.
