php - Laravel Socialite - 在重定向之前保存 URL

Question

我正在使用 Laravel 5.4 和 Socialite，因此我的用户可以使用 Facebook 登录。

我的网站使用子域 newyork.example.com, paris.example.com example.com

回调登录的 Facebook URL 重定向必须是 absolute 所以我设置了 http://example.com

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

当我在 route login/facebook 时，我可以使用 HTTP_POST 查看原始 URL paris.example.com

当我在路线 login/facebook/callback 时 HTTP_POST 是 example.com 因为重定向的 URL 是 example.com。我尝试将 URL 保存在 session var 中，但 $_SESSION 是空的。

问题

在 facebook 登录回调重定向后，我该如何获取原始 url。 ？因此，如果我使用 paris.example.com 开始登录过程，我将被重定向到 example.com，然后我将获得要重定向的保存 url

session .php

'cookie' => 'laravel_session',

    /*
    |--------------------------------------------------------------------------
    | Session Cookie Path
    |--------------------------------------------------------------------------
    |
    | The session cookie path determines the path for which the cookie will
    | be regarded as available. Typically, this will be the root path of
    | your application but you are free to change this when necessary.
    |
    */

    'path' => '/',

    /*
    |--------------------------------------------------------------------------
    | Session Cookie Domain
    |--------------------------------------------------------------------------
    |
    | Here you may change the domain of the cookie used to identify a session
    | in your application. This will determine which domains the cookie is
    | available to in your application. A sensible default has been set.
    |
    */

    'domain' => env('SESSION_DOMAIN', '.localhost.com'),

    /*
    |--------------------------------------------------------------------------
    | HTTPS Only Cookies
    |--------------------------------------------------------------------------
    |
    | By setting this option to true, session cookies will only be sent back
    | to the server if the browser has a HTTPS connection. This will keep
    | the cookie from being sent to you if it can not be done securely.
    |
    */

    'secure' => env('SESSION_SECURE_COOKIE', false),

    /*
    |--------------------------------------------------------------------------
    | HTTP Access Only
    |--------------------------------------------------------------------------
    |
    | Setting this value to true will prevent JavaScript from accessing the
    | value of the cookie and the cookie will only be accessible through
    | the HTTP protocol. You are free to modify this option if needed.
    |
    */

    'http_only' => true,

我是这样用的，很管用

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();
}

在 handleSocialCallback 函数中，用户登录后

Auth::login($checkUser);
return redirect(Session::get('redirect'));
Session::forget('redirect');
