Answer 1

Update 2018 - laravel 5.6 - socialite 3.0

It's little bit tricky for something that looks/should be easy, but anyway this is how i make things works for me.

Server side

you can find those instructions and more details in socialite docs

Installation

composer require laravel/socialite

Configuration

in config/services.php add

'facebook' => [

    'client_id'     => env('FACEBOOK_CLIENT_ID'),
    'client_secret' => env('FACEBOOK_CLIENT_SECRET'),
    'redirect'      => env('FACEBOOK_CALLBACK_URL'),
],

in .env file add

FACEBOOK_CLIENT_ID=paste_client_id_here
FACEBOOK_CLIENT_SECRET=paste_client_secret_here
FACEBOOK_CALLBACK_URL=https://www.example.com/auth/facebook/callback

in routes/web.php add

Route::get('auth/facebook/', 'Auth\FacebookController@redirect')->name('auth.facebook');

Route::get('auth/facebook/callback', 'Auth\FacebookController@callback')->name('auth.facebook.callback');

in App\Http\Controllers\Auth add new controller FacebookController.php

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\User;
use Socialite;

class FacebookController extends Controller {

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function redirect()
    {
        return Socialite::driver('facebook')->redirect();
    }


    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function callback(Request $request)
    {
        try {

            $facebookAccount = Socialite::driver('facebook')->user();

            // your logic here...

            return redirect()->route('your.route.name');


        } catch (Exception $e) {


            return redirect()->route('auth.facebook');
        }
    }
}

Facebook side

go to https://developers.facebook.com/apps and create new app (if you don't have one already)

and make sur your app settings are like below in those screen shots:

Important note

If you are developing in your local machine, you have to use tools like ngrok that provide a secure link to your localhost.

In the facebook login settings change https://www.example.com with the url provided by ngrok something like https://8b0215bc.ngrok.io.

It is the only way that worked for me while developing in my local machine.

Answer 2

Create a provider under your config/services.php file

'facebook' => [
    'client_id' => 'your-fb-client-id',
    'client_secret' => 'your-fb-secret',
    'redirect' => 'http://your-redirect.com/route',
],

now you can create a controller with following code

//this function will redirect users to facebook login page
public function facebook()
{
    return \Socialize::with('facebook')->redirect();
}

public function callback()
{
    $user = \Socialize::with('facebook')->user();

    //now we have user details in the $user array
     dd($user);

}

and this is your route

Route::get('facebook', 'LoginController@facebook');

Route::get('callback', 'LoginController@callback');

Answer 3

In your composer.json add- "laravel/socialite": "~2.0",

"require": {
        "laravel/framework": "5.0.*",
        "laravel/socialite": "~2.0",

the run composer update

In config/services.php add:

//Socialite
    'facebook' => [
        'client_id'     => '1234567890444',
        'client_secret' => '1aa2af333336fffvvvffffvff',
        'redirect'      => 'http://laravel.dev/login/callback/facebook',
    ],

You need to create two routes, mine are like these:

//Social Login
Route::get('/login/{provider?}',[
    'uses' => 'AuthController@getSocialAuth',
    'as'   => 'auth.getSocialAuth'
]);


Route::get('/login/callback/{provider?}',[
    'uses' => 'AuthController@getSocialAuthCallback',
    'as'   => 'auth.getSocialAuthCallback'
]);

You also need to create controller for the routes above like so:

<?php namespace App\Http\Controllers;

 use Laravel\Socialite\Contracts\Factory as Socialite;

 class AuthController extends Controller
 {

       public function __construct(Socialite $socialite){
           $this->socialite = $socialite;
       }


       public function getSocialAuth($provider=null)
       {
           if(!config("services.$provider")) abort('404'); //just to handle providers that doesn't exist

           return $this->socialite->with($provider)->redirect();
       }


       public function getSocialAuthCallback($provider=null)
       {
          if($user = $this->socialite->with($provider)->user()){
             dd($user);
          }else{
             return 'something went wrong';
          }
       }

 }

and finally add Site URL to your Facebook App like so:
