Dynamic facebook app credentials for Laravel 5.1 socialite - facebook

Question

We are trying to use dynamic facebook app credentials for Laravel 5.1 socialite.
config/services.php
'facebook' => [
'client_id' => 'xxxx',
'client_secret' => 'xxxx',
'redirect' => 'http://example.com/facebook-callback',
],
On my controller file:
public function getConnectFacebook()
{
return Socialite::driver('facebook')->redirect();
}
public function getFacebookCallback()
{
$user = Socialite::driver('facebook')->user();
}
We tried to overwrite the facebook driver this way:
public function getConnectFacebook()
{
Config::Set("services.facebook.client_id", "dynamic_app_id");
Config::Set("services.facebook.client_secret", "dynamic_app_secret");
Config::Set("services.facebook.redirect", "dynamic_app_redirect");
return Socialite::driver('facebook')->redirect();
}
But it was not working. Could you please let me know how we can achieve this?
Thanks.

Answer 1

like this
return Socialite::driver('facebook')->redirect()->setTargetUrl('your callback url');

Answer 2

Here is my solution.
private function makeFacebookDriver($domain){
//grab and set your config values from database or array. Don't do Config::Set.
$config['client_id'] = '';//grab fb id based from db based on domain
$config['client_secret'] = '';//grab fb secret from db based on domain
$config['redirect'] = 'http://'.$domain.'/fbcallback';
return Socialite::buildProvider(\Laravel\Socialite\Two\FacebookProvider::class, $config);
}
then use the function instead of calling Socialite::driver('Facebook');
$fb = $this->makeFacebookDriver('www.test.com');
return $fb->redirect();

Answer 3

just use it in your controller
use Laravel\Socialite\Two\FacebookProvider;
config
$config = [
'client_id' => '969935-d61celu1qck667krmbgql.apps.googlesercontent.com',
'client_secret' => 'sHrnnOz3Fmz4',
'redirect' => 'http://localhost:8000/api/login/facebook/callback'
];
$user= Socialite::buildProvider(FacebookProvider::class, $config)->stateless();
return $user->redirect();
stateless in callback
$userSocial =$config = [
'client_id' => '969d61celu1qck667krmbgql.apps.googlesercontent.com',
'client_secret' => 'sHrnnO3Fmz4',
'redirect' => 'http://localhost:8000/api/login/facebook/callback'
];
$user=Socialite::buildProvider(FacebookProvider::class, $config)-
>stateless()->user();
api or web.php
Route::get('login/{provider}', 'SocialController#redirect');
Route::get('login/{provider}/callback','SocialController#Callback');

You could also do a simple find and replace.
Let's say you have a config file like this
'facebook' => [
'client_id' => '{ID}',
'client_secret' => '{SECRET}',
'redirect' => '{REDIRECT}',
],
Now within your controller you can do something like this.
$fileName = 'path/to/file.php';
$configData = file_get_contents($file);
$configData = str_replace('{ID}','dynamic_id',$configData);
$configData = str_replace('{SECRET}','dynamic_secret',$configData);
$configData = str_replace('{REDIRECT}','dynamic_link',$configData);
file_put_contents($file, $configData);
That's it, nothing fancier.
