Laravel Socialite with Facebook not logging in - facebook

I'm following the documentation exactly.
https://github.com/laravel/socialite and https://laravel.com/docs/5.1/authentication#social-authentication
I've created my app on Facebook and got everything working. When I click my log in with Facebook button, it authorizes the app and takes me back to my site.
However, it doesn't show me as logged in. If I dd() instead of the redirect below, I get all of the data from my Facebook account. But the pages that are only visible to logged in users, aren't visible.
Here is my controller:
public function redirectToProvider()
{
return Socialite::driver('facebook')->redirect();
}
public function handleProviderCallback()
{
$user = Socialite::driver('facebook')->user();
return redirect('my-profile')
->with('message', 'You have signed in with Facebook.');
}
Here are my routes:
Route::get('login/facebook', 'Auth\AuthController#redirectToProvider');
Route::get('login/facebook/callback', 'Auth\AuthController#handleProviderCallback');
Socialite is installed properly in composer.json. The classes are in config/app.php and the IDs for my FB app are in config/services.php.
Any ideas as to why it's not working?

In the handleProviderCallback method you need to create and authenticate the user returned by the driver.
Create the user if doesn't exist:
$userModel = User::firstOrNew(['email' => $user->getEmail()]);
if (!$userModel->id) {
$userModel->fill([.....]);
$userModel->save();
}
Then authenticate the user:
Auth::login($userModel);
Your method will look like this:
public function handleProviderCallback() {
$user = Socialite::driver('facebook')->user();
$userModel = User::firstOrNew(['email' => $user->getEmail()]);
if (!$userModel->id) {
$userModel->fill([.....]);//Fill the user model with your data
$userModel->save();
}
Auth::login($userModel);
return redirect('my-profile')
->with('message', 'You have signed in with Facebook.');
}

laravel 5.2 redirect after registration by id

I've found here some examples, but they are not answering how to redirect registered user to his own profile by id.
protected $redirectPath = '/profile/view/'.$user->id; Did not help.
I have a project where users are being authorized without email confirmation and they are sent to /home after registration.
Route to user profile is: /profile/view/id (id is unique of course).
I managed to send them there after login (in AuthController :
public function authenticated($request,$user)
{
return redirect('/profile/view/'.$user->id);
}
but redirect to profile after registration I can't handle.
Approach 1.
Let users view their own profile without ID.
route (make ID optional):
Route::get('profile/view/{id?}', ...);
controller:
public function view($id = null) {
if (is_null($id) { //set id of currently signed in user if id == null
$id = Auth::user()->id;
}
//continue as before
}
Approach 2.
Modify routes so redirect happens to correct url.
Note: order of routes is important
Route::get('profile/view', function() {
return redirect()->route('profile.view', ['id' => Auth::user()->id]);
});
Route::get('profile/view/{id}', ...)->name('profile.view');
Note: in both approaches auth middleware is a must, else you going to get error if user is not logged in (PHP error: Trying to get property of non-object on line X)
With both approaches you just redirect user to profile/view:
is shown profile (without ID in URL)
is redirected to proper url profile/view/ID.

Exchanging Facebook Auth Code for Access Token using the PHP SDK

I am trying to build a server-to-server auth flow using the Facebook PHP SDK and no Javascript, as outlined here. So far, I have successfully created a LoginUrl that lets the User sign in with Facebook, then redirect back to my App and check the state parameter for CSFR protection.
My Problem is, that I can't seem to get the API-call working that should swap my Auth Code for an access token. I pillaged every similar problem anyone else that Google was able to find had encountered for possible solutions.
Yet the end result was always the same: no access token, no error message that I could evaluate.
Researching the topic yielded the following advice, which I tested:
The URL specified in the App Settings must be a parent folder of $appUrl.
use curl to make the request instead of the SDK function api()
I've been at this for 2 days straight now and really could use some help.
<?php
require '../inc/php-sdk/src/facebook.php';
// Setting some config vars
$appId = 'MY_APP_ID';
$secret = 'MY_APP_SECRET';
$appUrl = 'https://MY_DOMAIN/appFolder';
$fbconfig = array('appId'=>$appId, 'secret'=>$secret);
$facebook = new Facebook($fbconfig);
// Log User in with Facebook and come back with Auth Code if not yet done
if(!(isset($_SESSION['login']))){
$_SESSION['login']=1;
header('Location: '.$facebook->getLoginUrl());
}
// process Callback from Facebook User Login
if($_SESSION['login']===1) {
/* CSFR Protection: getLoginUrl() generates a state string and stores it
in "$_SESSION['fb_'.$fbconfig['appId'].'_state']". This checks if it matches the state
obtained via $_GET['state']*/
if (isset($_SESSION['fb_'.$fbconfig['appId'].'_state'])&&isset($_GET['state'])){
// Good Case
if ($_SESSION['fb_'.$fbconfig['appId'].'_state']===$_GET['state']) {
$_SESSION['login']=2;
}
else {
unset($_SESSION['login']);
echo 'You may be a victim of CSFR Attacks. Try logging in again.';
}
}
}
// State check O.K., swap Code for Token now
if($_SESSION['login']===2) {
$path = '/oauth/access_token';
$api_params = array (
'client_id'=>$appId,
'redirect_uri'=>$appUrl,
'client_secret'=>$secret,
'code'=>$_GET['code']
);
$access_token = $facebook->api($path, 'GET', $api_params);
var_dump($access_token);
}
The easiest way I found to do this is to extend the Facebook class and expose the protected getAccessTokenFromCode() method:
<?php
class MyFacebook extends Facebook {
/** If you simply want to get the token, use this method */
public function getAccessTokenFromCode($code, $redirectUri = null)
{
return parent::getAccessTokenFromCode($code, $redirectUri);
}
/** If you would like to get and set (and extend), use this method instead */
public function setAccessTokenFromCode($code)
{
$token = parent::getAccessTokenFromCode($code);
if (empty($token)) {
return false;
}
$this->setAccessToken($token);
if (!$this->setExtendedAccessToken()) {
return false;
}
return $this->getAccessToken();
}
}
I also included a variation on the convenience method I use to set the access token, since I don't actually need a public "get" method in my own code.

CakePHP 2.3.1 Facebook authentication

I'm using CakePHP 2.3.1 and this plugin: https://github.com/webtechnick/CakePHP-Facebook-Plugin to implement a facebook authentication. I followed this screen cast http://tv.cakephp.org/video/webtechnick/2011/01/12/nick_baker_--_facebook_integration_with_cakephp but it doesn't work, I can't receive the Facebook user information. I mean $this->Connect->user() always return null.
First make sure your user as granted access to your app. Then make a call to retrieve personal details through the api(/me) => $this->Connect->user()
Personally, I use this
public function beforeFilter(){
if($this->Connect->FB->getUser() != 0){
$this->set('facebookUser', $this->Connect->user());
}
Initiating ConnectComponent will populate (or not) the Auth Session. If no id is to be found, redirect user to a login dialog.
Call this method from beforefilter..and save the post data received in some variable like fb_data here.
protected function _valdiateFbRequest() {
if (!isset($this->request->data['signed_request'])) {
// not a valid request from fb
// throw exception or handle however you want
return;
}
$this->signedRequest = $this->request->data['signed_request'];
$this->fb_data=$this->Connect->registrationData(); //save fb data
unset($this->request->data['signed_request']);
if (empty($this->request->data)) {
$this->Security->csrfCheck = false;
}
// validate the request
}

fosfacebook bundle unable to get user information from facebook

I'm using Symfony 2.1 for a project & I'm using FOSFacebook bundle integrated with FOSUser bundle. when the user logs into my application no information is retrieved! i mean this line goes in exception :
namespace Acmes\UserBundle\Security\User\Provider;
class FacebookProvider implements UserProviderInterface {
//...
public function loadUserByUsername($username) {
//...
try {
$fbdata = $this->facebook->api('/me');
} catch (FacebookApiException $e) {
$fbdata = null;
}
//...
}
}
when the user logs in, the button change to 'logout' but i get the error :
"The user is not authenticated on facebook"
which means that $fbdata is null & no info has returned back from facebook application.
any solution? thanks!:)
I faced the same problem as yours.
Something must go wrong during your installation process of fosuserbundle and fosfacebook bundle.
Double check your settings with the following tutorial.

How do I avoid redirecting 404's to the login form in a Zend Framework 1 controller plugin?

I made a controller plugin to handle authentication. If a user tries to access a page without being logged in, it saves the route of the page he was trying to access, forwards to the login page, and then when the user logs in, it redirects him to where he was trying to go.
But if the user tries to access a nonexistent page while logged out, then it still forwards to the sign-in form, but when the user signs in, it brings up an error.
How do I bring up a 404 error before the user signs in? I think I need to detect whether the route is valid within dispatchLoopStartup(). How do I do that? Or is there some other way of doing this?
class Chronos_Controller_Plugin_Auth extends Zend_Controller_Plugin_Abstract
{
public function dispatchLoopStartup(Zend_Controller_Request_Abstract $request)
{
$auth = Zend_Auth::getInstance();
if ($auth->hasIdentity()) {
$request->setParam('userName', $auth->getIdentity());
} else {
$request->setParam('origModule', $request->getModuleName())
->setParam('origController', $request->getControllerName())
->setParam('origAction', $request->getActionName())
->setModuleName('default')
->setControllerName('sign')
->setActionName('in');
}
}
}
Try something like this:
public function dispatchLoopStartup(Zend_Controller_Request_Abstract $request)
{
$dispatcher = Zend_Controller_Front::getInstance()->getDispatcher();
$auth = Zend_Auth::getInstance();
if ($auth->hasIdentity()) {
$request->setParam('userName', $auth->getIdentity());
} else if ($dispatcher->isDispatchable($request)) {
$request->setParam('origModule', $request->getModuleName())
->setParam('origController', $request->getControllerName())
->setParam('origAction', $request->getActionName())
->setModuleName('default')
->setControllerName('sign')
->setActionName('in');
}
}
