AngularJs optional header param (token) - angularjs

My app is using token based auth, but a guest can get data too. So for requesting data, I decided to use ngResource lib and write a factory for it.
First, the auth controller gets a token from the server and places it to localstorage. After that $place proceeds to the home page where the home controller requests data through Home factory.
My problem is that if I use guest mode and then authorize with user data, my app can't add the token header to $resource object.
After reload page everything is working properly, but I need do it without reloading. Here is my factory code
.factory('placeResource', ['$resource','$window', function($resource,$window) {
var get_token = function(){
if ($window.localStorage.token){
return 'token '+$window.localStorage.token
}
};
return $resource("/api/:resourceName/place/:placeId",
{ resourceName: '#_resourceName', placeId: '#placeId'},
{
query: {
method: 'GET',
isArray: true,
headers: { 'Authorization': get_token() }}
}
);
}]);

add config in angular resource

I am using http-auth-interceptor for authentication. In http-auth-interceptor, I use the following way to login:
var data = 'username=' + encodeURIComponent(user.userId) + '&password=' + encodeURIComponent(user.password);
$http.post('api/authenticate', data, {
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
},
ignoreAuthModule: 'ignoreAuthModule'
})
ignoreAuthModule is used to tell ignoreAuthModule that this login method will be ignored by the auth interceptor.
Now, I have some request with $resource, like:
.factory('SomeDataService', function ($resource) {
return $resource('api/some/data', {}, {
'get': { method: 'GET'}
});
})
I want SomeDataService.get() is also ignored by the auth interceptors, because I need to control the 401 error by myself.
So, my question is, is there any way for ngResource that I can set config like that in $http.
[update based on comment]
I have listened the login-required event:
$rootScope.$on('event:auth-loginRequired', function (rejection) {
$log.log(rejection);
// I need to get the request url and for some specific url, need to do something.
$rootScope.loginPopup();
});
But the 'rejection' parameter has no context data of request I need. I need to get the request url and check, for some specified url, I need to do something.
After checking the document of ngResource, I got the solution as below:
.factory('SomeDataService', function ($resource) {
return $resource('api/some/data', {}, {
'get': { method: 'GET', ignoreAuthModule: 'ignoreAuthModule'}
});
})
Just add the config item as above. It will be equivalent ad:
$http.post('api/some/data', data, {
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
},
ignoreAuthModule: 'ignoreAuthModule'
})
ngResource module is build on top of $http.Hence it is not possible to configure all the stuffs you can do with $http in $resource.I think the below link will be guide you to have a clear understanding on $http and $resource

Token authorization - Browser throws Login form

I am working on a token implementation into Angular/.Net application. My part is the front-end. What's happening is that when UI sends a request with the expired token and the server replies with 401 I cannot intercept that before the Browser raises the Login form. As the result I cannot send a request to refresh the token. Can someone please give me an idea how that is supposed be managed? I will provide code just don't know what's to show.
Thanks
Adding code:
var response = $http({
method: "GET",
dataType: "json",
params: params,
headers: {
'Content-Type': "application/xml; charset=utf-8",
},
url: someurl
});
response = response.then(function (data) {
return data.data;
});
response.catch(function (data) {
$q.reject(data);
});
// Return the promise to the controller
return response;
The problem is that I cannot redirect on UI because Browser throws Login form before my code is hit when the server returns 401.
Make ajax request, and if you get 401 then redirect to login page.
P.s. for better understanding provide your code how you implement ajax request. Which module do you use for front-end auth? I recommend satellizer
Added:
I guess you need the following configuration on angular
var app = angular.module('App', ['satellizer'])
.config(function() {
/* your config */
}
.run(function($rootScope, $location, $auth) {
// Check auth status on each routing,
// Redirect to login page, if user is not authenticated or if token expired
$rootScope.$on('$routeChangeStart', function(event, next, current) {
if (!$auth.isAuthenticated()) {
$location.path('/auth/login');
}
});
});

AngularJS $resource GET params appear in URL

My REST backend [ based on NodeJS/express/mongojs] is complaining 404 (not found) when Params are attached as part of URL. Backend rest interface is coded as below;
var express = require('express');
var router = express.Router();
router.get('/login', auth.signin); //auth.signin is code to verify user
Above REST service is consumed by AngularJS based frontend through $resource as below;
Definition:
angular.module('myapp').factory('signinmgr', function($resource) {
return $resource("http://localhost:3000/login", {}, {
'get': {
method: 'GET',
headers: {
'Content-Type': 'application/json'
}
}});
Usage:
signinmgr.get({'username':'myname', 'password':'mypass'}, function(data){
//success
}, function(x){
//failed
});
Problem:
Frontend code above produces a URL to consume REST service where parameters are part of URL i.e. http://localhost:port/login?username=myname&password=mypass [if I use GET method, POST is OK]. I wanted my front end to keep URL as http://localhost:port/login and post any parameters through body as backend is using req.body.paramName to read those. [Actual Solution]
If (1) cannot be done, and my frontend is sending params as part of URL, I needed help as to know how to equip my backend to allow this URL with parameters so that backend doesnt return 404 as the base URL http://localhost:port/login is already there.
PS: for (1), I tried this thread with data:{username:'',password:''} but of no use. Please help if I am missing something very obvious or some concept.
Try the $http service instead:
angular.module('myapp').factor('signinmgr', function($http) {
return {
login: function (username, password) {
$http.post("http://localhost:3000/login", {
username: username,
password: password
}
}
};
});
signinmgr.login('myname', 'mypass').then(function(data){
//success
}, function(x){
//failed
});
Each request that my nodejs/expressjs backend receives has three places for passed attributes;
params{}
query{}
body{}
My problem (1) cannot be fixed in case I want to use GET method since with GET request parameters are visible as part of URL i.e. http://localhost:port/login?username=myname&password=mypass. To send my username/password I had to use POST that sends parameters as part of body{}.
My problem (2) was that I was using GET and mistakenly looking for parameters in body{} of request. Instead, parameters passed as part of URL in GET request are added to query{} of the request.

Angular $http post with custom headers

I am new to angular and am from .net framework. I need to post a angular request to .net service, where it expects two custom headers from the client.
angular post command:
var request = $http(
{
url: "http://localhost:53585/api/myService/Validate",
method: "POST",
data: JSON.stringify(payload),
headers: { 'first_token': sessionService.first_token, 'second_token': sessionService.second_token }
});
But in the service side, I can see only first_token in the request header and not the second token. What I am missing here?
Issue is with my service. I figured out and restarted the IIS and then service was able to read both the headers token
I found this method in a forum, it works.
return this.http.post<any>('https://yourendpoint', { username, password }, { headers: new HttpHeaders().set('Authorizaion', 'your token')})
.pipe(map(user => {
// login successful if there's a jwt token in the response
if (user && user.token) {
// sto`enter code here`re user details and jwt token in local storage to keep user logged in between page refreshes
localStorage.setItem('currentUser', JSON.stringify(user));
}
console.log(user);
return user;

$resource invalidation in angularjs

I have this use case where I pass authToken to every request and this token changes everytime the person logins.
app.factory('Comment', function ($resource, localStorageService, $cacheFactory) {
return $resource('http://localhost:port/comments/:id', {"id":"#id", port:':9000'}, {
query: { method:'GET', isArray: true , headers: {'X-AUTH-TOKEN':'authToken='+localStorageService.get("authToken")}},
save: { method:'POST',headers: {'X-AUTH-TOKEN':'authToken='+localStorageService.get("authToken")}},
update: {method:'PUT' ,headers: {'X-AUTH-TOKEN':'authToken='+localStorageService.get("authToken")}},
delete : {method: 'DELETE',headers: {'X-AUTH-TOKEN':'authToken='+localStorageService.get("authToken")}},
get : { method: 'GET', headers: {'X-AUTH-TOKEN':'authToken='+localStorageService.get("authToken")}}
});
The behaviour I am seeing is that if the authToken changes for some reason the $resource keeps adding the previous authToken while sending the request. I am using the $http directly for login and for any commenting related stuff I am using $resource. Am I missing something?
After login I make sure that my localStorage has the newly created token but the request are using the previous authToken till I refresh the page after which it adds the correct header I know that the $resource uses some kind of caching and tried to remove the $http cache like this after loggin in.
$cacheFactory.get('$http').removeAll();
but didnt't help
It's because token is assigned once when factory code executes. Try this instead:
get : { method: 'GET', headers: {
'X-AUTH-TOKEN': function(){
return 'authToken=' + localStorageService.get("authToken");
}
}}
