What is the correct way to request a new JWT authentication token via refresh tokens within AngularJS?
I already have an implementation that, on every API request, checks whether the session needs refreshing and, if so, requests a new token from the webserver. But, if a page makes 3 calls at once it requests a new refresh token for each call which seems incorrect - I would think it should only update the token once.
Is there a way to block other calls or should I put the refresh on an interval and not do it via interceptors?
Interceptor request method
request = (config: angular.IRequestConfig) => {
this.setBearerToken(config);
var responsePromise = this.$q.when(config);
if (config.url !== this.tokenUrl) {
const factSession = this.$injector.get("factSession") as Session;
if (factSession.shouldRefreshToken()) {
responsePromise = factSession
.refreshSession()
.then(() => {
this.setBearerToken(config);
return config;
});
}
}
return responsePromise;
}
Just enhance your refreshSession method, so it wont refresh several times.
var refreshPromise;
refreshSession: () => {
if (!refreshPromise) {
refreshPromise = $http.get(...);
refreshPromise.finally(() => refreshPromise = null);
}
return refreshPromise;
}

I am working on a project using the Spotify Web JS API. I am able to successfully get the AccessToken, but I am coming across the issue of the token expiring and have found that I need to get a refresh token. Here is how I am currently getting the access token.
useEffect(() => {
const hash = window.location.hash;
let token = window.localStorage.getItem("token");
if (!token && hash) {
token = hash
.substring(1)
.split("&")
.find((elem) => elem.startsWith("access_token"))
.split("=")[1];
window.location.hash = "";
window.localStorage.setItem("token", token);
setToken(token);
}
spotify.setAccessToken(token);
spotify.getMyRecentlyPlayedTracks({ limit: 50 }).then((data) => {
setRecentlyPlayed(data.items);
});
spotify.getMySavedAlbums().then((user) => {
console.log("Saved albums:", user);
});
spotify.getFollowedArtists().then((user) => {
setNumberArtistsFollowing(user.artists.total);
});
spotify.getMyCurrentPlayingTrack().then((data) => {
if (data) {
setCurrentlyPlaying(data);
}
});
spotify.getMe().then(setUserProfile);
setToken(token);
}, []);
I have no experience with refresh tokens as this is my first project with tokens in general. Could anyone give me a hand? I am thinking that I need to request a refresh token in my code if the localstorage contains a token, do this on every page load regardless of whether the token is expired or not. I am unsure of how to get this refresh token though. Thank you!
I am consuming REST APIs from react app. My ASP .NET web api server is returning cookies in response to axios get request but i am UNABLE to get set-cookie header from the response. BOTH app and api are running locally.
I can see the cookies in postman and in the browser window, but not in react app. Please help me sort it out.
React app
signInWithEmailAndPassword = (email, password) => {
axios.defaults.withCredentials = true
return new Promise((resolve, reject) => {
axios.get('https://localhost:44399/api/Cross/GetTest')
.then(response => {
var value = response.headers["set-cookie"] // it is always undefined
});
});
};

I'm trying to use Google Cloud Print(GCP) API, but I can't make it works.
Maybe I've understood bad the workflow because is the first time I'm using the google api, please help me to understand how to make it works.
Initial considerations:
I'm trying to implement it in reactJS, but It is indifferent because the logic to make GCP works is independent of the technology. Then you also can help me understand the workflow.
What exactly I want:
To make my first test, I am looking to get all information about my printer.
What I did:
I created a project in: https://console.developers.google.com
Inside the project created, I created a credential:
create credentials -> OAuth client ID
And I chose Application type: Web, and also configure the restrictions to source and redirection to my localhost.
Manually in https://www.google.com/cloudprint, I added my printer, I made a test printing a PDF and was OK.
I created a project in reactJS to get the information of my printer I've added.
Component:
Explanation:
I'm using a component react-google-login to obtain easily the user accessToken: https://github.com/anthonyjgrove/react-google-login
This component only obtains the access token and save it in localStorage, in a variable called googleToken and it draws a button to call a function to obtain the information about the printer.
code:
import React, { Component } from 'react'
import GoogleLogin from 'react-google-login';
import { connect } from 'react-redux'
import { getPrinters } from '../actions/settings'
class Setting extends Component {
responseGoogle(response) {
const accessToken = response.accessToken
localStorage.setItem('googleToken', accessToken)
}
render() {
return (
<div>
<GoogleLogin
clientId="CLIENT_ID_REMOVED_INTENTIONALLY.apps.googleusercontent.com"
buttonText="Login"
onSuccess={this.responseGoogle}
onFailure={this.responseGoogle}
/>
<button
onClick = {() => {
this.props.getPrinters()
}}
>test printer</button>
</div>
)
}
}
const mapStateToProps = state => {
return {
state: state
}
}
const mapDispatchToProps = dispatch => {
return {
getPrinters() {
dispatch(getPrinters())
}
}
}
export default connect(
mapStateToProps,
mapDispatchToProps
)(Setting)
Action or Function to get information printer:
Explanation:
I'm passing the parameter printerid to get information about that printer.
In authorization, I'm using OAuth ... because in the documentation says that(second paragraph).: https://developers.google.com/cloud-print/docs/appInterfaces
The next two headers I wrote it because I tried solutions as:
Google Cloud Print API: User credentials required
Google Cloud Print User credentials required
code:
import axios from 'axios'
axios.defaults.headers.common['Authorization'] = 'OAuth ' + localStorage.getItem('googleToken')
axios.defaults.headers.common['scope'] = 'https://www.googleapis.com/auth/cloudprint'
axios.defaults.headers.common['X-CloudPrint-Proxy'] = 'printingTest'
const getPrinters = () => {
return () => {
return axios.get('https://www.google.com/cloudprint/printer'
, {
params: {
printeid: 'PRINTER_ID_REMOVED_INTENTIONALLY'
}
}
)
.then(response => {
console.log('response of google cloud print')
console.log(response)
})
}
}
export { getPrinters }
Error:
After all explained before, I got the next error:
User credentials required
Error 403
Note:
I'm using CORS plugin by recommendation of:
Chrome extensions for silent print?
because initially, I had cors error.
Any suggestion or recommendation would be very useful, thanks.
I've resolved my problem, my main problem about User Credential required were because I was using the incorrect access token and It was because I was getting the access token incorrectly.
I'm going to explain my whole solution because there are few examples of codes with this API.
Solutions:
The steps described were Ok until the fourth step where I used the external component react-google-login to trying to get the access token, instead I used googleapis module: Link Github googleapis
Also to avoid CORS problem(and not use CORS chrome plugin) I wrote the requests to Google API in server side.(NODEJS)
I had also a problem in the frontend when I tried to generate a popup to give permission for printer(problems about CORS), my solution was to use this very simple module for authentication: Link Github oauth-open
General scheme:
Explanation:
Knowing I have all data described in my question post(until the third step).
Authentication:
The next step in getting a URL and use it to the user can authenticate.
As I said before I used the module oauth-open in the frontend to generate the popup and only this module need the URL. To get the URL in the backend I used the endpoint /googleurl, where here I used the method generateAuthUrl of the module googleapis to generate the URL.
After that In the frontend, I got the authentication_code(that returned the module oauth-open), I send It to my endpoint /googletoken and here I process the authentication_code to generate access token, refresh token and expiration date with the method getToken of the module googleapis. Finally, these data are stored in the database.
Print:
For print, since the frontend, I send what data I need send to the printer. I used my endpoint /print
In the backend endpoint, my logic was the next:
Recover tokens and expiration date from database, with the expiration date check if the token has expired, and if It has already expired then gets another token and replace the old access token with the new one, replacing also with the new expiration date, to obtain this new data only is necessary call to method refreshAccessToken of module googleapis.Note: the refresh token never expires.
After having the access token updated, use it to send data to the printer with Google route(.../submit)
Code:
All the next codes are in only 1 file
Some data as validation, static variables, error handler, etc, has been removed to better understanding.
Route get URL authentication.
const express = require('express');
const google = require('googleapis');
const router = express.Router();
var OAuth2 = google.auth.OAuth2;
const redirect_url = 'http://localhost:3001/setting'; //Your redirect URL
var oauth2Client = new OAuth2(
'CLIENT ID', //Replace it with your client id
'CLIEND SECRET', //Replace it with your client secret
redirect_url
);
var url = oauth2Client.generateAuthUrl({
access_type: 'offline',
scope: 'https://www.googleapis.com/auth/cloudprint'
});
router.get('/googleurl', (req, res) => {
return res.status(200).send({
result: { googleURLToken: url }
});
});
To get tokens using the authentication code and save these in the database.
const Setting = require('../models/setting'); // My model(Mongoose)
router.post('/googletoken', (req, res) => {
oauth2Client.getToken(req.body.code, function (err, tokens) {
oauth2Client.credentials = tokens;
// If refresh token exits save it
// because the refresh token it returned only 1 time! IMPORTANT
if (tokens.hasOwnProperty('refresh_token')) {
let setting = new Setting();
setting.refreshTokenGoogle = tokens.refresh_token;
setting.expirationTokenGoogle = tokens.expiry_date;
setting.tokenGoogle = tokens.access_token;
setting.save()
.then((settingCreated) => {
return res.status(200).send({
message: 'OK'
});
})
}
});
});
To print
const axios = require('axios');
const moment = require('moment');
router.post('/print',async (req, res) => {
const tickeProperties = {
'version': '1.0',
'print': {
'vendor_ticket_item': [],
'color': { 'type': 'STANDARD_MONOCHROME' },
'copies': { 'copies': 1 }
}
};
const accessToken = await getTokenGoogleUpdated();
axios.get(
'https://www.google.com/cloudprint/submit',
{
params: {
printerid : printerID, // Replace by your printer ID
title: 'title printer',
ticket: tickeProperties,
content : 'print this text of example!!!',
contentType: 'text/plain'
},
headers: {
'Authorization': 'Bearer ' + accessToken
}
}
)
.then(response => {
return res.status(200).send({
result: response.data
});
})
}
);
async function getTokenGoogleUpdated() {
return await Setting.find({})
.then(async setting => {
const refreshTokenGoogle = setting[0].refreshTokenGoogle;
const expirationTokenGoogle = setting[0].expirationTokenGoogle;
const tokenGoogle = setting[0].tokenGoogle;
const dateToday = new Date();
// 1 minute forward to avoid exact time
const dateTodayPlus1Minute = moment(dateToday).add(1, 'm').toDate();
const dateExpiration = new Date(expirationTokenGoogle);
// Case date expiration, get new token
if (dateExpiration < dateTodayPlus1Minute) {
console.log('Updating access token');
oauth2Client.credentials['refresh_token'] = refreshTokenGoogle;
return await oauth2Client.refreshAccessToken( async function(err, tokens) {
// Save new token and new expiration
setting[0].expirationTokenGoogle = tokens.expiry_date;
setting[0].tokenGoogle = tokens.access_token;
await setting[0].save();
return tokens.access_token;
});
} else {
console.log('Using old access token');
return tokenGoogle;
}
})
.catch(err => {
console.log(err);
});
}
I hope It helps you if you want to use Google Cloud Print to not waste a lot of time as I did.
The important part there is a scope https://www.googleapis.com/auth/cloudprint which is not obvious and took one day for me to figure out.
I am coding a SPA in react.js and I am using redux-api to handle backend connection. I want to do a sync action to refresh the auth token before doing the main action; this way, every time I will do an action to the backend I will be sure that the token is valid.
const endpoints = {
{
url: '/some/url',
crud:true,
prefetch:[
({actions, dispatch, getState}, cb) =>{
actions.auth_token.post(JSON.stringify({
token: "my token",
refreshToken: "my_refresh_token"
}),null, (err, data) =>{
if(err){
// HANDLE ERROR
}
setToken(data)
})
}
]
}
}
const api = reduxApi(endpoints)
How can I call the prefetch function in a sync way? So first the token refreshes and then the Action?
EDIT
We can do the stuff async, the important is the final call to cb(), here is the example
const endpoints = {
{
url: '/some/url',
crud:true,
prefetch:[
({actions, dispatch, getState}, cb) =>{
let mills = new Date().getTime()
const { token, generationTime, accessTokenLife, refreshTokenLife, refreshToken } = localStorage
// Conditions: exixts token, it is expired, refresh token is not expired
if(token && generationTime + accessTokenLife - 500 < mills && generationTime + refreshTokenLife - 500 > mills){
dispatch(actions.token_refresh.get(null, null, (err, data) =>{
if(err){
dispatch(setError(err))
}else{
refreshTokenData(data)
}
cb()
}))
}else{
cb()
}
}
]}}
const api = reduxApi(endpoints)
You may not need to request the token every time you do an async action. In fact, I'd encourage you not to.
You can request the token when you authenticate the user and cache it using web storage. Now instead of sending a network request to retrieve the users token every time you need it, you simply check the browsers cached storage. If the token for the user exists then the user has successfully authenticated. Otherwise, the user has not logged in and you can redirect the user to the authentication page.
Since that was not actually an answer to your problem but rather a different way to solve your problem I will also answer your question in a way that is more inline with the question. You should be able to utilize promise chaining to request the user's token and then once that resolves, do any other action.
I will explain in an abstract way that is not explicity related to redux-api that you should be able to adapt to redux-api specific constructs easy enough.
const actionOne = () => {
actions.post(myJson)
.then(response => actionTwo(response))
.catch(error => console.log(error))
}
An important modification you would need to make is to convert actions.auth_token.post to return a promise. Then you can chain other actions to the resolution of that promise. If you are not familiar with promises MDNs documentation is quite good. For more information on converting a function from callbacks to promises this Stack Overflow answer is quite detailed.
I am trying to redirect to Identity Server's default login page when calling an API controller method from Angular's $http service.
My web project and Identity Server are in different projects and have different Startup.cs files.
The web project Statup.cs is as follows
public class Startup
{
public void Configuration(IAppBuilder app)
{
AntiForgeryConfig.UniqueClaimTypeIdentifier = Thinktecture.IdentityServer.Core.Constants.ClaimTypes.Subject;
JwtSecurityTokenHandler.InboundClaimTypeMap = new Dictionary<string, string>();
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = "Cookies",
});
var openIdConfig = new OpenIdConnectAuthenticationOptions
{
Authority = "https://localhost:44301/identity",
ClientId = "baseballStats",
Scope = "openid profile roles baseballStatsApi",
RedirectUri = "https://localhost:44300/",
ResponseType = "id_token token",
SignInAsAuthenticationType = "Cookies",
UseTokenLifetime = false,
Notifications = new OpenIdConnectAuthenticationNotifications
{
SecurityTokenValidated = async n =>
{
var userInfoClient = new UserInfoClient(
new Uri(n.Options.Authority + "/connect/userinfo"),
n.ProtocolMessage.AccessToken);
var userInfo = await userInfoClient.GetAsync();
// create new identity and set name and role claim type
var nid = new ClaimsIdentity(
n.AuthenticationTicket.Identity.AuthenticationType,
Thinktecture.IdentityServer.Core.Constants.ClaimTypes.GivenName,
Thinktecture.IdentityServer.Core.Constants.ClaimTypes.Role);
userInfo.Claims.ToList().ForEach(c => nid.AddClaim(new Claim(c.Item1, c.Item2)));
// keep the id_token for logout
nid.AddClaim(new Claim("id_token", n.ProtocolMessage.IdToken));
// add access token for sample API
nid.AddClaim(new Claim("access_token", n.ProtocolMessage.AccessToken));
// keep track of access token expiration
nid.AddClaim(new Claim("expires_at", DateTimeOffset.Now.AddSeconds(int.Parse(n.ProtocolMessage.ExpiresIn)).ToString()));
// add some other app specific claim
nid.AddClaim(new Claim("app_specific", "some data"));
n.AuthenticationTicket = new AuthenticationTicket(
nid,
n.AuthenticationTicket.Properties);
n.Request.Headers.SetValues("Authorization ", new string[] { "Bearer ", n.ProtocolMessage.AccessToken });
}
}
};
app.UseOpenIdConnectAuthentication(openIdConfig);
app.UseResourceAuthorization(new AuthorizationManager());
app.Map("/api", inner =>
{
var bearerTokenOptions = new IdentityServerBearerTokenAuthenticationOptions
{
Authority = "https://localhost:44301/identity",
RequiredScopes = new[] { "baseballStatsApi" }
};
inner.UseIdentityServerBearerTokenAuthentication(bearerTokenOptions);
var config = new HttpConfiguration();
config.MapHttpAttributeRoutes();
inner.UseWebApi(config);
});
}
}
You will notice that the API is secured with bearer token authentication, whereas the rest of the app uses OpenIdConnect.
The Identity Server Startup.cs class is
public class Startup
{
public void Configuration(IAppBuilder app)
{
var policy = new System.Web.Cors.CorsPolicy
{
AllowAnyOrigin = true,
AllowAnyHeader = true,
AllowAnyMethod = true,
SupportsCredentials = true
};
policy.ExposedHeaders.Add("Location");
app.UseCors(new CorsOptions
{
PolicyProvider = new CorsPolicyProvider
{
PolicyResolver = context => Task.FromResult(policy)
}
});
app.Map("/identity", idsrvApp =>
{
idsrvApp.UseIdentityServer(new IdentityServerOptions
{
SiteName = "Embedded IdentityServer",
SigningCertificate = LoadCertificate(),
Factory = InMemoryFactory.Create(
users: Users.Get(),
clients: Clients.Get(),
scopes: Scopes.Get())
});
});
}
X509Certificate2 LoadCertificate()
{
return new X509Certificate2(
string.Format(#"{0}\bin\Configuration\idsrv3test.pfx", AppDomain.CurrentDomain.BaseDirectory), "idsrv3test");
}
}
Notice that I have added a CorsPolicy entry in order to allow the Web App to hopefully redirect to the Login page. In addition, the Cors policy exposes the Location request header, since it contains the url that I would like to redirect to.
The Web Api controller method is secured using the Authorize Attribute, like so
[HttpPost]
[EnableCors(origins: "*", headers: "*", methods: "*")]
[Authorize]
public PlayerData GetFilteredPlayers(PlayerInformationParameters parameters)
{
var playerInformation = composer.Compose<PlayerInformation>().UsingParameters(parameters);
var players = playerInformation.Players
.Select(p => new {
p.NameLast,
p.NameFirst,
p.Nickname,
p.BirthCity,
p.BirthState,
p.BirthCountry,
p.BirthDay,
p.BirthMonth,
p.BirthYear,
p.Weight,
p.Height,
p.College,
p.Bats,
p.Throws,
p.Debut,
p.FinalGame
});
var playerData = new PlayerData { Players = players, Count = playerInformation.Count, Headers = GetHeaders(players) };
return playerData;
}
The angular factory makes a call to $http, as shown below
baseballApp.factory('playerService', function ($http, $q) {
return {
getPlayerList: function (queryParameters) {
var deferred = $q.defer();
$http.post('api/pitchingstats/GetFilteredPlayers', {
skip: queryParameters.skip,
take: queryParameters.take,
orderby: queryParameters.orderby,
sortdirection: queryParameters.sortdirection,
filter: queryParameters.filter
}).success(function (data, status) {
deferred.resolve(data);
}).error(function (data, status) {
deferred.reject(status);
});
return deferred.promise;
}
}});
When this call occurs, the response status is 200, and in the data, the html for the login page is returned.
Moreover, I can see on Chrome's Network tab that the response has a Location header with the url of the Login page. However, if I set up an http interceptor, I only see the Accept header has been passed to the javascript.
Here are the http headers displayed in Chrome's network tab:
The response does not have the Access-Control-Allow-Origin header for some reason.
So I have the following questions:
Is there a way I could get access to the Location header of the response in the angular client code to redirect to it?
How might I be able to get the server to send me a 401 instead of 200 in order to know that there was an authentication error?
Is there a better way to do this, and if so, how?
Thanks for your help!
EDIT:
I have added a custom AuthorizeAttribute to determine what http status code is returned from the filter.
The custom filter code
public class BearerTokenAutorizeAttribute : AuthorizeAttribute
{
private const string AjaxHeaderKey = "X-Requested-With";
private const string AjaxHeaderValue = "XMLHttpRequest";
protected override void HandleUnauthorizedRequest(System.Web.Http.Controllers.HttpActionContext actionContext)
{
var headers = actionContext.Request.Headers;
if(IsAjaxRequest(headers))
{
if (actionContext.RequestContext.Principal.Identity.IsAuthenticated)
actionContext.Response.StatusCode = System.Net.HttpStatusCode.Forbidden;
else
actionContext.Response.StatusCode = System.Net.HttpStatusCode.Unauthorized;
}
base.HandleUnauthorizedRequest(actionContext);
var finalStatus = actionContext.Response.StatusCode;
}
private bool IsAjaxRequest(HttpRequestHeaders requestHeaders)
{
return requestHeaders.Contains(AjaxHeaderKey) && requestHeaders.GetValues(AjaxHeaderKey).FirstOrDefault() == AjaxHeaderValue;
}
I have observed two things from this: first, the X-Requested-With header is not included in the request generated by the $http service on the client side. Moreover, the final http status returned by the base method is 401 - Unauthorized. This implies that the status code is changed somewhere up the chain.
Please don't feel like you have to respond to all the questions. Any help would be greatly appreciated!
You have probably configured the server correctly since you are getting
the login page html as a response to the angular $http call -> it is
supposed to work this way:
angularjs $http
Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning that the outcome (success or error) will be determined by the final response status code.
You are getting a 200 OK response since that is the final response as the redirect is instantly followed and it's result resolved as the $http service outcome, also the response headers are of the final response
One way to achieve the desired result - browser redirect to login page:
Instead of redirecting the request server side (from the web project to the Identity Server) the web api controller api/pitchingstats/GetFilteredPlayer could return an error response (401) with a json payload that contains a {redirectUrl: 'login page'} field or a header that could be read as response.headers('x-redirect-url')
then navigate to the specified address using window.location.href = url
Similar logic can often be observed configured in an $httpInterceptors that handles unauthorized access responses and redirects them to the login page - the redirect is managed on the client side
