How to integrate OAuth2.0 login in electron - oauth

I am newbie to electron and I am currently trying to implement an OAuth2.0 API which requires a callback URI. Url callback requires valid URL (https://myserver.com/sucess). so i tried this code snippet but does not work.
// Your GitHub Applications Credentials
var options = {
client_id: 'your_client_id',
client_secret: 'your_client_secret',
scopes: ["user:email", "notifications"] // Scopes limit access for OAuth tokens.
};
app.on('ready', () => {
// Build the OAuth consent page URL
var authWindow = new BrowserWindow({ width: 800, height: 600, show: false, 'node-integration': false });
var githubUrl = 'https://github.com/login/oauth/authorize?';
var authUrl = githubUrl + 'client_id=' + options.client_id + '&scope=' + options.scopes;
authWindow.loadURL(authUrl);
authWindow.show();
function handleCallback (url) {
console.log(url);
}
// Handle the response from GitHub - See Update from 4/12/2015
authWindow.webContents.on('will-navigate', function (event, url) {
handleCallback(url);
});
authWindow.webContents.on('did-get-redirect-request', function (event, oldUrl, newUrl) {
handleCallback(newUrl);
});
// Reset the authWindow on close
authWindow.on('close', function() {
authWindow = null;
}, false);
});
also, i used angular js route but does not work either.
so I'm wondering if there is a way to run server inside electron app to serve app from URL (https://localhost:3000) and if so how this will affect app behavior at packaging and distributing time, i means does the app will run from the same port
... any suggestions will help about how i can approach this problem. thank you

I had the same issue last week, i needed to integrate my electron app with vkontakte api which uses form of OAuth protocol. What you can do:
1) You launch local node http server, probably in separate process as i did.
2) You request code through oauth link and set redirect uri as http://127.0.0.1:8000/, for some reason https://localhost didn't work for me.
3) In main process you wait for message with code from server, on server implemented corresponding logic (when you receive request and code in it send through process.send back to parent message with code)
4)You request access token from main process, you shouldn't change redirect_uri. You again catch response from your server.
5) You get access_token, you kill server...
But when i did all this i read their docs till end and there was stated that standalone apps, like mine for desktop could receive token in easier way through "implicit flow", and you can get your token with only one call. Hope my experience could be extrapolated on your issue. Good luck!

Can login or register only with Firefox using Sanctum API authentication (CSRF token mismatch)

I am developing an SPA with Laravel 9, Vuejs 3 and Sanctum. I am newbie to vue and to Sanctum and I use the sanctum API authentication instead of the token authentication.
At this stage I am in dev and run the embedded laravel server for laravel app and vite server for SPA.
Everything is going smoothly when I sign in and out using the Firefox browser. But when I use Google Chrome or other browser based upon chrome (Brave, Vivaldi, chromium) I cannot sign in nor register. I get a CSRF token mismatch response.
Here are my login an register methods from vuex 's store
actions: {
async register({ commit }, form) {
console.log("in register of index");
await axiosClient.get("/sanctum/csrf-cookie");
return axiosClient.post("/api/register", form).then(({ data }) => {
console.log("data dans index");
console.log(data);
return data;
});
},
async login({ commit }, user) {
await axiosClient.get("/sanctum/csrf-cookie");
return axiosClient
.post("/api/login", user)
.then(({ data }) => {
commit("SET_USER", data);
commit("SET_AUTHENTICATED", true);
//commit("setAuth", true);
return data;
})
.catch(({ response: { data } }) => {
commit("SET_USER", {});
commit("SET_AUTHENTICATED", false);
});
},
Could somebody help me making out what is wrong or missing?
Edited after Suben's response
I read from somebody that the trouble in Chrome could come from the domain being localhost instead of http://localhost in sanctum config.
Thus I did that and could manage to login with both browser. The trouble is that even with a satisfactory answer to login and the reception of the csrf-token now in both browser the store state is not set despite the answer in the .then function being a valid user object.
Moreover, doing 3 similar requests after that strange situation, the 3 of them being under the auth:sanctum middleware, the first failed with csrf-token mismatch, the second succeeded and the third failed also with csrf-token mismatch. Looking at the requests, they have exactly the same 3 cookies including one with the csrf-token.
My guess is, that RESTful APIs are stateless. That means, they do not worry about sessions. https://restfulapi.net/statelessness/
As per the REST (REpresentational “State” Transfer) architecture, the server does not store any state about the client session on the server-side. This restriction is called Statelessness.
When you login a user with Laravel's SPA authentication, then you ARE storing client session data on the server-side.
So you have two options:
You are moving the endpoint /api/login to web.php (logout too!) OR...
You are using the API token based login.
EDIT:
I had my problems at first too with Laravel Sanctums SPA authentication and Vue. There is a video, which goes through a lot of cases, that might help you aswell for the future (Configuration of cors.php and more): https://www.youtube.com/watch?v=It2by1dL50I

Amazon sp-api Authorisation Workflow Issue

Following the SP-API developer guide, I created an app to be able to access SP-API. The app is in published state now and we tried the authorisation workflow as per the amazon guide steps:
https://github.com/amzn/selling-partner-api-docs/blob/main/guides/en-US/developer-guide/SellingPartnerApiDeveloperGuide.md#amazon-seller-central-partner-network-authorization-workflow
We are using the website authorisation workflow, the steps 1-3 work as per the guide,
Step 1. Initiate the authorization from the Amazon Seller Central Partner Network.
Step 2. The selling partner consents to authorize your application, we authorise the app from seller Central and start the process, this url loads
https://sellercentral.amazon.com/apps/authorize/consent?application_id=amzn1.sp.solution.6cf699bd-f89a-4afd-b64e-7d21351aaaaa
Step 3. The selling partner signs into your website, we are redirected to the website login and that is done, then we get the amazon state and partner id as part of the url:
https://dashboard.aaa.com/api/amzn/login?amazon_callback_uri=https%3A%2F%2Fsellercentral.amazon.com%2Fapps%2Fauthorize%2Fconfirm%2Famzn1.sp.solution.6cf699bd-f89a-4afd-b64e-7d21351aaaa&amazon_state=MTY0MzgzMjI2NzU2OADvv71PY8KzGA0Iaih1Nzjvv71bHNqRGO-_ve-_ve-_ve-_vRnvv70a77-9eTF577-9Ee-_vRDvv70W77-9FEnvv73vv71ueO-_vR7vv73vv70PYu-_vUJd77-9B--_vTxF77-977-9f--_vQ%3D%3D&selling_partner_id=A2079RJZNKAAAA
Step 4. Amazon sends you the authorization information - Then we are redirected back to Seller Central -
https://sellercentral.amazon.com/apps/authorize/confirm/amzn1.sp.solution.6cf699bd-f89a-4afd-b64e-7d21351aaaa?state=1d477f90edfa493a1d15&amazon_state=MTY0MzgzMjI2NzU2OADvv71PY8KzGA0Iaih1Nzjvv71bHNqRGO-_ve-_ve-_ve-_vRnvv70a77-9eTF577-9Ee-_vRDvv70W77-9FEnvv73vv71ueO-_vR7vv73vv70PYu-_vUJd77-9B--_vTxF77-977-9f--_vQ==&selling_partner_id=A2079RJZNKAAAA&redirect_uri=https://dashboard.aaa.com/api/amzn/redirect
We are getting the sp_oauth_code in the url and tried using that to request for refresh token via POSTMAN request but unable to proceed to request the token from amazon oauth service.
We are getting error 400 as response, this is request format from the postman code section:
var axios = require('axios');
var qs = require('qs');
var data = qs.stringify({
'grant_type': 'authorization_code',
'code': 'ANnGBdMPnXAlrMyfUdwaaa',
'client_id': 'amzn1.application-oa2-client.cf71c857f2fd4f2c968851619bdaaaaa',
'client_secret': 'bba375434456e9917fcd5539c4324cc0e3182cccb9f1694ce3c63bee4f1aaaaa',
'redirect_uri': 'https://dashboard.aaa.com/api/amzn/redirect'
});
var config = {
method: 'post',
url: 'https://api.amazon.com/auth/o2/token',
headers: { },
data : data
};
axios(config)
.then(function (response) {
console.log(JSON.stringify(response.data));
})
.catch(function (error) {
console.log(error);
});
We are sending data as x-www-form-urlencoded as Json in the POST request.
Any pointers on what we could differently or check for any missing params - any inputs on what to look for would be greatly appreciated.
The SP-API documentation is a little vague on this as it says you should include the grant type, code, seller id and secret as query parameters which by definition means within the url.
You actually need to add them to the body of the POST request.
This is an interesting discussion which revealed the above to me: https://github.com/amzn/selling-partner-api-docs/issues/79
Hope it helps.

How to obtain a Google oauth2 refresh token?

The following code uses the Google oauth2 mechanism to sign in a user. We need to process updates to the user's calendar while the user is offline, so we ultimately need the 'refresh token'. Does the result from grantOfflineAccess() return the refresh token (below, I can see that response.code holds a value that might be the refresh token)?
How can I get a refresh token that can be used (server side) to create new access keys for offline access to a user's Google calendar?
<script type="text/javascript">
function handleClientLoad() {
gapi.load('client:auth2', initClient);
}
function initClient() {
gapi.client.init({
apiKey: 'MY_API_KEY',
clientId: 'MY_CLIENT_ID.apps.googleusercontent.com',
discoveryDocs: ['https://www.googleapis.com/discovery/v1/apis/calendar/v3/rest'],
scope: 'https://www.googleapis.com/auth/calendar'
}).then(function () {
var GoogleAuth = gapi.auth2.getAuthInstance();
GoogleAuth.signIn();
GoogleAuth.grantOfflineAccess().then(function (response) {
var refresh_token = response.code;
});
});
}
</script>
<script async defer src="https://apis.google.com/js/api.js"
onload="this.onload=function(){};handleClientLoad()"
onreadystatechange="if (this.readyState === 'complete') this.onload()">
</script>
There is a reason why you are having a problem getting a refresh token out of JavaScript. That reason being that it's not possible.
JavaScript is a client side programming language, for it to work you would have to have your client id and client secret embedded in the code along with the refresh token. This would be visible to anyone who did a view source on the web page.
I think you realize why that's probably a bad idea. The main issue is that gapi won't return it the library just doesn't have that ability (not that I have tried in raw JavaScript to see if the OAuth server would return it if I asked nicely).
You will need to switch to some server side language. I have heard that this can be done with Node.js, but haven't tried myself. And Java, PHP, Python are all valid options too.
Based from this post, you should include the specific scopes in your requests. Your client configuration should have $client->setAccessType("offline"); and $client->setApprovalPrompt("force");.
After allowing access, you will be returned an access code that you can exchange for an access token. The access token returned is the one you need to save in a database. Later on, if the user needs to use the calendar service, you simply use the access token you already saved.
Here's a sample code:
/*
* #$accessToken - json encoded array (access token saved to database)
*/
$client = new Google_Client();
$client->setAuthConfig("client_secret.json");
$client->addScope("https://www.googleapis.com/auth/calendar");
$_SESSION["access_token"] = json_decode($accessToken, true);
$client->setAccessToken($_SESSION['access_token']);
$service = new Google_Service_Calendar($client);
//REST OF THE PROCESS HERE

Is there an API method in Slack-Api to set (change) Events API Request URLs so I can do this in code?

To use Events API for Slack App development, there is a setting for "Events API Request URLs" as described in doc:
In the Events API, your Events API Request URL is the target location
where all the events your application is subscribed to will be
delivered, regardless of the team or event type.
There is a UI for changing the URL "manually" at api.slack.com under
"Event Subscriptions" section in settings. There is also url_verification event after changing the Request URL described here.
My question - Is there an API call (method) so I can update the endpoint (Request URL) from my server code?
For example, in Facebook API there is a call named subscriptions where I can change webhook URL after initial setup - link
Making a POST request with the callback_url, verify_token, and object
fields will reactivate the subscription.
PS. To give a background, this is needed for development using outbound tunnel with dynamic endpoint URL, e.g. ngrok free subscription. By the way, ngrok is referenced in sample "onboarding" app by slack here
Update. I checked Microsoft Bot Framework, and they seems to use RTM (Real Time Messaging) for slack which doesn't require Request URL setup, and not Events API. Same time, e.g. for Facebook they (MS Bot) instruct me to manually put their generated URL to webhook settings of a FB app, so there is no automation on that.
Since this question was originally asked, Slack has introduced app manifests, which enable API calls to change app configurations. This can be used to update URLs and other parameters, or create/delete apps.
At the time of writing, the manifest / manifest API is in beta:
Beta API — this API is in beta, and is subject to change without the usual notice period for changes.
so the this answer might not exactly fit the latest syntax as they make changes.
A programatic workflow might look as follows:
Pull a 'template' manifest from an existing version of the application, with most of the settings as intended (scopes, name, etc.)
Change parts of the manifest to meet the needs of development
Verify the manifest
Update a slack app or create a new one for testing
API List
Basic API list
Export a manifest as JSON: apps.manifest.export
Validate a manifest JSON: apps.manifest.validate
Update an existing app: apps.manifest.update
Create a new app from manifest: apps.manifest.create
Delete an app: apps.manifest.delete
Most of these API requests are Tier 1 requests, so only on the order of 1+ per minute.
API Access
You'll need to create and maintain "App Configuration Tokens". They're created in the "Your Apps" dashboard. More info about them here.
Example NodeJS Code
const axios = require('axios');
// Change these values:
const TEMPLATE_APP_ID = 'ABC1234XYZ';

Hope this helps anyone else looking to update Slack applications programatically.
No, such a method does not exist in the official documentation. There might be an unofficial method - there are quite a few of them actually - but personally I doubt it.
But you don't need this feature for developing Slack apps. Just simulate the POST calls from Slack on your local dev machine with a script and then do a final test together with Slack on your webserver on the Internet.

Authentication for Node.js App with Angular.js and iOS Clients

I've tried to read as many different answers and posts as possible, but I still can't quite settle on a solution that fits my needs. I'm trying to work out the best (most efficient, but mostly more secure) way to handle user authentication, log in, etc.
I have a Node.js server, running on Express; I have an Angular.js web app; and I have an iOS app. I expose a RESTful API with Express/Node.js.
Cookies
The first things I read said to use cookies, and to store a session id/login token on the server side (hashed) and on the client side (unhashed). The client would transfer this id with each request, the server would hash it, parse it and process the request accordingly. This does not feel RESTful (not a huge issue), but more importantly, would I have to duplicate my API: one for username/password authentication (e.g. done via curl) and one for cookie-based authentication (e.g. my web app)?
Another problem with this: what I would do if I had multiple connections from the one user, e.g. they're logged in in two browsers, an iPhone and an iPad. Would my storage of their session ids need to now be an array?
HTTP Basic Auth
The next idea was to use HTTP Basic Auth (with SSL), which seems easy enough, but is not recommended because you need to transfer a username and password with each request. If I were to do it with HTTP Basic Auth, would I then store the username and password in cookies (or HTML local storage) to allow for 'Remember Me' functionality? Or could I combine the two: use HTTP Basic Auth for the actual requests (post a new post, etc.) and just use a session id stored in a cookie for the initial log in sequence/remember me aspects?
Is transmitting a session id more secure than just transmitting the user's password? How?
The session id is going to act ostensibly as a password, so to me transmitting it would have the same security issues as transmitting a password.
Basic Auth seems to be supported across all platforms, which is ideal. The main downside seems to be needing to transfer client authentication data with each request. Is there a way to mitigate this issue?
OAuth
OAuth seems like overkill for my needs. I think I would lose the ability to do curl commands to test my API. How is OAuth an improvement over the cookies method?
As you can probably tell, I'm a little confused by the diverse information available, so if you have a set of good links—applicable to this scenario—I would love to read them. I'm trying to find a solution that fits across all platforms, but is still as secure as possible. Also, if I have any of my terminology wrong, please correct me because it will make searching easier for me.
Thanks.
Update:
I've been thinking about this problem, and I've had an idea. Please tell me if this is dumb/insecure/any feedback, because I'm not sure if it's good.
When the user logs in, we generate a random session id (salted etc.). This optional session id is sent to the client, which the client can store (e.g. in cookies) if they choose; the session id is stored in the database.
This session id is then optionally sent with each request as either an HTTP Authentication header or query string, or the client can just send the username and password if they want (which gives us our regular REST API). At the server end, we check first for a session id parameter, if it's not present, we check for username/password. If neither are there—error.
On the server, we check that the session id is associated with the correct username. If it is, we complete the request.
Every time the user logs in, we create a new session id or delete the current one, and send this with the response to the log in request.
I think this lets me use the regular REST API, where appropriate, with Basic Auth, and maintain sessions/remember me functionality. It doesn't solve the multiple log ins issue, but otherwise I think this way should would. Please let me know.
I would use a token based authentication where you can send a token (automatically) with each request. You'll have to log in once, the server will provide you with a token which you can then use to send with each request. This token will be added to the HTML header, so that you don't have to modify each request to the browser.
You can set certain calls in the API so that they always need a token, while others might not be token protected.
For Express, you can use express-jwt (https://www.npmjs.org/package/express-jwt)
var expressJwt = require('express-jwt');
// Protect the /api routes with JWT
app.use('/api', expressJwt({secret: secret}));
app.use(express.json());
app.use(express.urlencoded());
If you want to authenticate you can create this function in your express server:
app.post('/authenticate', function (req, res) {
//if is invalid, return 401
if (!(req.body.username === 'john.doe' && req.body.password === 'foobar')) {
res.send(401, 'Wrong user or password');
return;
}
var profile = {
first_name: 'John',
last_name: 'Doe',
email: 'john#doe.com',
id: 123
};
// We are sending the profile inside the token
var token = jwt.sign(profile, secret, { expiresInMinutes: 60*5 });
res.json({ token: token });
});
And for protected calls something that starts with /api:
app.get('/api/restricted', function (req, res) {
console.log('user ' + req.user.email + ' is calling /api/restricted');
res.json({
name: 'foo'
});
});
In your Angular application you can login with:
$http
.post('/authenticate', $scope.user)
.success(function (data, status, headers, config) {
$window.sessionStorage.token = data.token;
$scope.message = 'Welcome';
})
.error(function (data, status, headers, config) {
// Erase the token if the user fails to log in
delete $window.sessionStorage.token;
// Handle login errors here
$scope.message = 'Error: Invalid user or password';
});
And by creating an authentication interceptor, it will automatically send the token with every request:
myApp.factory('authInterceptor', function ($rootScope, $q, $window) {
return {
request: function (config) {
config.headers = config.headers || {};
if ($window.sessionStorage.token) {
config.headers.Authorization = 'Bearer ' + $window.sessionStorage.token;
}
return config;
},
response: function (response) {
if (response.status === 401) {
// handle the case where the user is not authenticated
}
return response || $q.when(response);
}
};
});
myApp.config(function ($httpProvider) {
$httpProvider.interceptors.push('authInterceptor');
});
If you have to support old browsers which do not support local storage. You can swap the $window.sessionStorage with a library like AmplifyJS (http://amplifyjs.com/). Amplify for example uses whatever localstorage is available. This would translate in something like this:
if (data.status === 'OK') {
//Save the data using Amplify.js
localStorage.save('sessionToken', data.token);
//This doesn't work on the file protocol or on some older browsers
//$window.sessionStorage.token = data.token;
$location.path('/pep');
}
}).error(function (error) {
// Erase the token if the user fails to log in
localStorage.save('sessionToken', null);
// Handle login errors here
$scope.message = 'Error: Invalid user or password';
});
And the authintercepter we swap for:
angular.module('myApp.authInterceptor', ['myApp.localStorage']).factory('authInterceptor', [
'$rootScope',
'$q',
'localStorage',
function ($rootScope, $q, localStorage) {
return {
request: function (config) {
config.headers = config.headers || {};
config.headers.Authorization = 'Bearer ' + localStorage.retrieve('sessionToken');
return config;
},
response: function (response) {
if (response.status === 401) {
}
return response || $q.when(response);
}
};
}
]);
You can find everything except AmplifyJS in this article:
http://blog.auth0.com/2014/01/07/angularjs-authentication-with-cookies-vs-token/
Have a look to the yeoman generator for angular and node? The generator-angular-fullstack have a very nice structure for user authentification using passport.
You can see an example here :
the code: https://github.com/DaftMonk/fullstack-demo
the result: http://fullstack-demo.herokuapp.com/
Hope it helps!
I use generator-angular-fullstack, the /api services are not secured, get your _id from /api/users/me, logout, and go to /api/users/your_id_here, you will figure out that the /api not secured.
