Laravel 5.2 Socialite Facebook API login redirect error
My Facebook login has suddenly stopped working using the Socialite package with Laravel 5.2. I have had it fully functional for a few days now and it just seems to of dropped off. I am fairly new to Laravel so please have some grace if it is something easy.
I get this error:
"The www.facebook.com page isn't working. www.facebook.com redirected you too many times."
I have tried restarting the local server, running commands like php artisan config:clear . Also tried installing with composer running version "laravel/socialite": "^2.0" . I can't help but think it is something actually in the Facebook Developer Apps API config but everything looks okay!
I will provide my code just in case anyone who has the time to help and can spot any bugs. I used this link as a guide to go off https://blog.damirmiladinov.com/laravel/laravel-5.2-socialite-facebook-login.html#.WK8bGBKLRBw
.env

//send off a request and to FB and get a token
return Socialite::driver('facebook')->redirect();
}
public function handleProviderCallback(SocialAccountService $service)
{
$user = $service->createOrGetUser(Socialite::driver('facebook')->user());
auth()->login($user);
return redirect()->to('account/{id}/myaccount');
}
}
SocialAccountService.php

{
$account = SocialAccount::whereProvider('facebook')
->whereProviderUserId($providerUser->getId())
->first();
if ($account) {
return $account->user;
} else {
$account = new SocialAccount([
'provider_user_id' => $providerUser->getId(),
'provider' => 'facebook'
]);
$user = User::whereEmail($providerUser->getEmail())->first();
if (!$user) {
$user = User::create([
'email' => $providerUser->getEmail(),
'name' => $providerUser->getName(),
]);
}
$account->user()->associate($user);
$account->save();
return $user;
}
}
}
Right guys, if anyone is facing issues like this I can be fairly certain that your routes or callback URL is slightly incorrect, either within your developers.facebook.com account or your .env file config. In my case in my .env I had my callback with an additional trailing '/' .
Causing the redirect issue:
FACEBOOK_CALLBACK_URL=http://localhost:8000/auth/facebook/
Fixed the redirect issue:
FACEBOOK_CALLBACK_URL=http://localhost:8000/auth/facebook
The callback from Facebook appends '/callback?code=xxxxYOUR-TOKENxxxxxx'
So with that extra '/' it seemed to be confusing the callback causing the redirect loop.
