Laravel Development provides a simple, convenient  way to authenticate with OAuth providers using Laravel Socialite. Socialite currently supports authentication with Facebook, Twitter, LinkedIn, Google and GitHub.

    Adding Social Authentication.

To get started with Socialite, we install it with Composer:

composer require laravel/socialite

Socialite package successfully install after add providers and alias in config/app.php

         Providers:-

   'providers' => [

              // ...

              Laravel\Socialite\SocialiteServiceProvider::class,

       ],

           Alias:-   

      ‘aliases:  =>  [

                         // …

                        'Socialite' => Laravel\Socialite\Facades\Socialite::class,

       ],

         Create model:- SocialProvider

       protected $table = 'social_providers';

                protected $fillable =['id','user_id','provider_id','provider'];

               function user(){

                           return $this->belongsTo(User::class);

               }

Create migration for the table:-

   php artisan make:migration create_social_providers_table --create=social_providers

Put your code like this in database/migrations/…create_social_providers_table.php:

public function up(){

        Schema::create('social_providers', function (Blueprint $table) {

            $table->increments('id');

            $table->integer('user_id')->unsigned()->references('id')->on('users');

            $table->string('provider_id');

            $table->string('provider');

            $table->string('profile');

            $table->string('remember_token');

           $table->timestamps();

        }); }

• create SocialLoginController in your project
• Add below mentioned two classes at top of the controller:-

     use Auth;
     use Socialite;

• In SocialLoginController code look like this:-

// function create for index page

public function index()

{

return view('social_login.index');

}

// function create for redirect on provider

public function redirectToProvider($provider)

{

return Socialite::driver($provider)->redirect();

}

// function create for provider handle and create

public function handleProviderCallback($provider)

{

$user = Socialite::driver($provider)->user();

$authUser = $this->findOrCreateUser($user, $provider);

Auth::login($authUser, true);

return view('social_login.index' ,compact('authUser'));

}

public function findOrCreateUser($user, $provider)

{

$authUser = SocialProvider::where('provider_id', $user->id)->first();

if ($authUser) {

return $authUser;

}

$fileContents = file_get_contents($user->getAvatar());

// dd($fileContents);

File::put(public_path() . '/socialite_profile/' . $user->getId() . ".jpg", $fileContents);

return SocialProvider::create([

'user_id'     => $user->id,

'provider_id' => $user->id,

'provider' => $provider,

'profile' =>  $user->getId()

]);

}

Create Routes in routes/web.php

   Route::get('social/login',[ 'as'=> 'social.index', 'uses'=> 'social_login\SocialLoginController@index']);

   Route::get('auth/{provider}','social_login\SocialLoginController@redirectToProvider');

    Route::get('auth/{provider}/callback', 'social_login\SocialLoginController@handleProviderCallback');
