Php 如何将用户重定向到各自的提供商，如laravel 5.4中的facebook、twitter

将

$authUser->$provider==='twitter'

更改为您实际需要的正确测试，我想应该是

$provider=='twitter'
它将所有提供商重定向到facebook OnlyTanks作为您的帮助人…它工作得很好…非常感谢
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Socialite;
use App\User;
use Auth;

class SocialLoginController extends Controller
{

    public function redirectToProvider($provider)
    {
        return Socialite::driver($provider)->redirect();
    }
    public function handleProviderCallback($provider)
    {
        try{
            $user = Socialite::driver($provider)->user();

        }catch(Exception $e){
            return redirect('auth/{$provider}');
        }
        // dd($user);
        $authUser = $this->findOrCreateUser($user);

        Auth::login($authUser, true);

        if($authUser->$provider === 'twitter') {
            return redirect()->intended('https://twitter.com/');
        }

        return redirect()->intended('https://www.facebook.com/');
    }

    Private function findOrCreateUser($providerUser)
    {
        $authUser = User::where('provider_id', $providerUser->id)->first();

        if ($authUser){
            return $authUser;
        }

        return User::create([
            'name' => $providerUser->name,

            // 'profileUrl' => $twitterUser->profileUrl
            ]);
    }
