Using Laravel Socialite to login to facebook
I am new to Laravel however and I am following the tutorial on http://www.codeanchor.net/blog/complete-laravel-socialite-tutorial/, to login a user through Facebook into my application. However, almost everywhere I find a tutorial using either Github or Twitter for the Socialite Plugin provided in Laravel.
My problem is that on following everything in the tutorial, as I click on the "Login to Facebook" button, it throws an "Invalid Argument Exception" with No Socialite driver was specified.".
Another stack overflow question seemed to narrow things down: https://stackoverflow.com/questions/29673898/laravel-socialite-invalidargumentexception-in-socialitemanager-php-line-138-n
Stating that the problem is in the config/services.php
Now, i have the app_id and app_secret. However, the redirect link seems to be confusing as I can't find it on Facebook either. I am aware that this is where my app should go to Facebook for login, however, unsure of what it should be.
Does anyone have any idea on this.
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 AppHttpControllers;
use LaravelSocialiteContractsFactory 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:
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');
