I have used PHP SDK-4 for Facebook login in CakePHP 3 (beta version) which works fine.Now, I'm in need to fetch user data based on FB login and authenticate users. Am trying with Cake's Auth component. Initially, while trying to Auth users,
$this->Auth->setUser($user)
Got Error: Session was already started as we require session_start() for Facebook login. 1- Tried with enter link description here, and sessions [session_write_close()] etc..still it did not work. Could I get some shot on best way to authenticate users with Facebook login in site?
CakePHPs sessions are lazy started, that is, they are being started once your try to access the session in some way, and in case the session was started manually in beforehand, you'll receive that error, see Session::start().
You can easily workaround this by manually starting the session via CakePHP. The session object is available in the current request, so for example in your controller before using the SDK you could simply do something like
$this->request->session()->start();
and then the Facebook SDK should be able to pick it up.
As burzum already mentioned in the comments, the authentication should better be wrapped up in an authentication handler.
I would suggest having a look at HybridAuth, there's also a CakePHP plugin for seamless integration into CakePHPs auth mechanism, this might give you some ideas for a custom implemenation in case you need to use the v4 SDK, which isn't yet supported by HybridAuth.

This question may be super simple but I've been googling for a while now and haven't found an exact solution.
I'm trying to implement a Google Login using React for the frontend and Django for the backend.
How exactly would I do this? I have seen solutions where a token is sent over to the backend which then retrieves the necessary information from the Google API and either creates or retrieves a user from the database based on the token. However, this seemed to be based on JWT and I was wondering if it is possible to implement the same with the simple Django Auth Token?
Maybe I'm just really blind but I really wasn't able to find a suitable solution.
Thanks for your help!
I was actually working on this a few moments ago, after many fails in the past. It's quite a headache really trying to find a solution that works with React. I have however managed to easily setup google login on the React front end side with https://www.npmjs.com/package/react-google-login. This should be the first step you will need to take.
After that you will need to setup social login on the Django backend using django_allauth. Basically, the idea is once a user logs in via google or to be precise, clicks on the Login With Google button on the front end, a google access_token will be retrieved from Google and saved in local storage together with some other data. Only the access_token is of interest here. So you will then need to take this access_token and send it to the Django backend via a Rest API of a view that you will have setup. That will get the google user data saved in the database under social accounts, ultimately login them in the application. Everything from then on should continue as per your normal logins with email and username. That is if using JWT, a jwt token will be returned from the backend which you hopefully should be able to save in local storage. In my React app, I authenticate against this token, so as long as I have the token in local storage, a user is logged in.
Pratik Singh Chauhan does a good job explaining this in his Part 1 tutorial here -> https://medium.com/#pratique/social-login-with-react-and-django-i-c380fe8982e2 and Part 2 here -> https://medium.com/#pratique/social-login-with-react-and-django-ii-39b8aa20cd27
UPDATE: June 2022
Since Google is now moving to (GIS) Google Identity Services sign-in SDK, this method, although it works is now deprecated.
Here is a good link to help you setup react login with the new google GIS.

There are 2 methods you can use depending on your workflow, implicit or authorization. To maintain a similar workflow that the above code achieved, implicit workflow is the one that can give you both access_token and refresh_token that you will send to your backend api.
Here is another link with sample code for both workflows.
https://react-oauth.vercel.app/
Note you will need to use #react-oauth/google to configure the Google workflows in your code.

I am trying to setup user signup and login with a Cognito user pool, Facebook and Google. I have been able to create a signup page (by following this guide) with the app integration in Cognito but would like to host the signup page along with the rest of my app. This answer has been somewhat helpful but lacks detail. I can't really find any good examples or documentation.
You can try to do so using the authorize endpoint but it looks like this may not be possible completely. First time app authorizations seem to require the built-in UI. See my answer to a similar question here.
I am trying to register users via Facebook using django rest-auth.
As per the installation docs here, a rest call to register a user via facebook requires an "access token" and "code". I know what an access token is, but what is "code"?
First of all, you need to create a Facebook Application in the developers page. You will get a Facebook app code and a secret.
For using the /rest-auth/facebook/ method from the django-rest-auth, you need to send the access code (obtained using the javascript SDK) and the code of the Facebook Application.
Finally, before using this method, you have to go the the application back-office and create a social application, using the Facebook app code and the secret.
Unfortunately I'm struggling to understand the documentation provided by Facebook.
This is the scenario:
- Some of my iPhone Apps are also registered as Native/Desktop Apps on Facebook in order to support the Facebook Audience Network.
- I'm building a tool in python which will retrieve data from the reporting API in order to run some automated analysis on specific metrics (request, impressions and so on).
The question is: how do I retrieve this data?
The documentation for the reporting API is here: Reporting API
However I'm struggling with the access token.
It says that I could use the specific App Token available here: App Tokens
However by using such token, I get an error saying that app tokens can't be used for Desktop/Native Ads.
What is the correct way to do it then? Here is where I struggle to understand Facebook Documentation.
My guess is that I should use a User Access Token instead, generated for a user that is also the admin of the App for which I want to retrieve the insights.
What really freaks me out is that apparently, this can't be done with normal HTTP calls only but it requires instead to go through the Facebook Login Dialog. I also need to create another Facebook (web) app because there is no way to get a simple "User Object"... Everything needs to start and go through a registered Facebook App. And there's no way to go through these steps by using backend code only.
So... to recap... in order to read the Insights for a Native/Desktop Facebook App (APP_A), I have to:
- Create a new Web Facebook App (APP_B)
- Create a web interface somewhere for APP_B) which will trigger the Facebook Login Dialog and request the read_insights permission.
- Login through this web interface and generate a User Access Token
- Put this User Access Token in my backend code and run the scripts that retrieve the data provided by the Reporting API for APP_B
Really... to me... it doesn't make any sense to create a new Facebook App in order to access the data of another Facebook App.
Isn't there another better, simpler, quicker, cleaner way to achieve the same final result?
I'm building up an app that should allow the user to sign up / sign in with Facebook and then he should be able to login (always via Facebook) to the "main" website
To be honest it's a bit more complicated than this. That's because I'm using django-tastypie and django-allauth in the main website to allow sign up, login, and browsing of our API
Basically I want to make the mobile app user browse the tastypie API (accessible only if logged and if you're an user in the main website) and grant him the rights to add rows (like orders)
Here's what I have
A phonegap app with a working Facebook login (I'm working on that right now)
A website with django-allauth and django-tastypie that makes me register as a new user using the allauth's Facebook login
No trace on the main website if the mobile user is doing a sign up via Facebook (this is the problem)
I'm basically confused how I should work with access tokens and how to pass further parameters (I don't need only the Facebook infos to complete the registration, but some custom fields too)
Anyone got experiences on this or would like to expose his workflow?
One common way of doing things is to leave all registration related functionality up to the website. In your phonegap app you can simply point the user to /accounts/login/ using the In-App-Browser (IAB). The IAB has events like loadstart and exit that you should monitor. A simple way of monitoring whether or not the user is successfully logged in is to have him redirected to a specific url, say /accounts/login/complete/, at the end of the login. If you attach a token to that return url (as in /accounts/login/complete/?token=123) you will be able to parse that token in your app. You could simply use the session ID as a token.
A more secure way is to use the django-oauth2-provider app and actually implement a proper oauth handshake. Handling that is almost the same. Using IAB open /oauth/authenticate/, you will be asked to login using allauth, then an oauth2 confirmation dialog appears, after which the oauth grant code is passed to a success URL. You can pick that code up from phonegap and using AJAX calls from within the phonegap app you can fetch the oauth access token. Btw, django-rest-framework has builtin support for django-oauth2-provider (don't know about tastypie).
A completely different approach is to implement a Facebook login in your mobile app, completely independent from the web site. Once logged in you'll be handed over a Facebook access token. Now, you can send this token over to the web site. Given the token, the website can fetch the user (https://graph.facebook.com/me?access_token=...), check whether or not that user is already known, if so return an appropriate token/session for that user, if not, create the user account and also return a token.
