我正在使用Laravel 5.4和Socialite，所以我的用户可以使用Facebook登录。
我的网站可用于子域newyork.example.com，paris.example.com example.com
回调登录的Facebook URL重定向必须为absolute，因此我将http://example.com设置为
登录/ facebook
public function redirectToProvider()
{
$_SESSION['originalURL'] ="http://paris.example.com";
return Socialite::driver('facebook')
->scopes(['rsvp_event', 'public_profile'])
->redirect();
}
登录/ Facebook /回调
public function handleProviderCallback(SocialAccountService $service)
{
$user = $service->createOrGetUser(Socialite::driver('facebook')->user());
// $user->token;
Auth::login($user, true);
$originalURL = $_SESSION['originalURL'];
return redirect()->to($originalURL);
}
问题
当我进入route登录名/ facebook时，我可以使用paris.example.com查看原始URL HTTP_POST
当我在路由login/facebook/callback中时，由于重定向的URL是HTTP_POST，所以example.com是example.com。我尝试将URL保存在session var中，但$_SESSION为空。
问题
Facebook登录回调重定向后，如何获取原始URL。 ？因此，如果我使用paris.example.com开始登录过程，则将我重定向到example.com，然后获取要重定向的保存URL

参考方案
我用这种方式，这是工作
public function socialConnectRedirect($type, Request $request)
{
Session::put('redirect', $request->input('redirectTo'));
if($type=='facebook'){
return Socialite::driver($type)->scopes(['email', 'public_profile', 'user_birthday', 'user_location'])->redirect();
}
return Socialite::driver($type)->redirect();
}
用户登录后，在handleSocialCallback函数中
Auth::login($checkUser);
return redirect(Session::get('redirect'));
Session::forget('redirect');
