Laravel 5 Socialite - 动态更改身份验证重定向路径

Question

我正在尝试将社交名流整合到网站中，但遇到了一个问题，这应该是一件相当琐碎的事情 - 在社交提供商进行身份验证后更改用户的重定向位置。

我将使用 Socialite 来执行三项操作:

• 注册 - 向提供商进行身份验证，然后重定向至注册表。他们的姓名和电子邮件地址已填写，但还需要更多字段。
• 登录 - 典型登录场景，根据用户表检查提供商信息，如果匹配则登录
• 链接 - 用户已有一个有效帐户，但想要链接外部(Faceebook 或 Google)帐户。这将对用户进行身份验证，并将正确的社交媒体 ID 添加到用户表中的行中。问题是您在 services.php 文件中指定了身份验证重定向，我无法弄清楚如何在成功通过第三方提供商进行身份验证后更改用户的重定向位置。

这是我到目前为止所拥有的 -

路线:这似乎在社交提供商重定向时起作用，因为缺少 driver=facebook&action=login (例如)。理想情况下，我想指定在发出初始身份验证请求时将用户重定向到哪里 - 这只是我第一次尝试解决这个问题。

get('social-auth', function(AuthenticateUser $authenticateUser, Request $request) {
    $driver = $request->input('driver');
    $action = $request->input('action');

    return $authenticateUser->execute($request->has('code'), $driver, $action);
});

AuthenticateUser 类 - 希望这里的注释足够:

<?php namespace App;

use Illuminate\Database\Eloquent\ModelNotFoundException;
use Laravel\Socialite\Contracts\Factory as Socialite;
use Auth;
use Flash;

class AuthenticateUser
{
    /**
     * @var Socialite
     */
    private $socialite;
    /**
     * @var Auth
     */
    private $auth;

    public function __construct(Socialite $socialite, Auth $auth)
    {

        $this->socialite = $socialite;
        $this->auth = $auth;
    }

    /**

     * @param string $driver Driver to use, Facebook or Google

     * @return array|\Illuminate\Http\RedirectResponse|\Illuminate\Routing\Redirector
     */
    public function execute($hasCode, $driver, $type)
    {
        if (!$hasCode) {
            return $this->getAuthorizationFirst($driver);
        }

        // Get the User details from the Social Provider
        $socialUser = $this->socialite->driver($driver)->user();
        $socialUserArray = $socialUser->user;

        if ($driver == 'facebook') {
            // Get Facebook specific fields
            $first_name = $socialUserArray['first_name'];
            $last_name = $socialUserArray['last_name'];
        } else if ($driver == 'google') {
            // Get Google specific fields
            $first_name = $socialUserArray['name']['givenName'];
            $last_name = $socialUserArray['name']['familyName'];
        }
        $email = $socialUser->email;
        $id = $socialUser->id;

        // Perform an action - login, register, or link
        switch ($type) {
            case 'login':
                // Log the user in with the Facebook ID
                try {
                    if ($driver == 'facebook') {
                        $user = User::whereFacebookAuth($id)->firstOrFail();
                    } else {
                        $user = User::whereGoogleAuth($id);
                    }
                } catch (ModelNotFoundException $e) {
                    flash::error('Could not find a user associated with this ' . ucfirst($driver) . ' account.');
                    return redirect('auth/login');
                }
                Auth::login($user);
                return redirect('members');
                break;
            case 'register':

                $driver == 'facebook' ? Auth::user()->facebook_auth = $id : Auth::user()->google_auth = $id;
                Auth::user()->save();
                return ['status' => 'success'];
                break;
        }
    }

    /**
     * Authorize the user before proceeding
     * @param $driver

    private function getAuthorizationFirst($driver)
    {
        return $this->socialite->with($driver)->redirect('hopefully-somewhere-else'); 
    // Anything inside redirect doesn't seem to do anything
    }
}

Answer 1

我倾向于将提供商包含在我的 URL 中。例如:

Route::get('auth/{provider}', 'AuthController@redirectToProvider');
Route::get('auth/{provider}/callback', 'AuthController@handleProviderCallback');

这样我就可以从 Controller 操作中的请求访问提供程序名称:

public function callback($provider)
{
    $user = $this->socialite->driver($provider)->getUser();

    try {
        // Try and find user by their social profile UID
        $appUser = SocialAccount::whereUid($user->getId())
            ->whereProvider($provider)
            ->firstOrFail();

        Auth::loginUsingId($appUser->user_id);
    } catch (ModelNotFoundException $e) {
        if (Auth::user()) {
            // Attach social profile to logged in user
        } else {
            // User is not logged in, and account does not exist
            // Prompt to register
        }
    }
}
