Laravel 5 Socialite - 动态更改auth重定向路径

标签: laravel laravel-5 laravel-socialite

我正在尝试将社交网站纳入一个网站,并且遇到了一个应该做的相当简单的事情 - 在社交提供商进行身份验证后更改用户重定向的位置。

我将使用Socialite进行三项操作:

  • 注册 - 与提供商进行身份验证,然后重定向到注册表单。他们的姓名和电子邮件地址已填写,需要更多字段。
  • 登录 - 典型的登录方案,根据Users表检查提供商信息,如果匹配则登录
  • 链接 - 用户已拥有有效帐户,但希望关联外部(Faceebook或Google)帐户。这将对用户进行身份验证,并将适当的社交媒体ID添加到Users表中的行。 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 -

路由:这似乎适用于社交提供商重定向的时间,因为缺少driver=facebook&action=login(例如)。理想情况下,我想在初始身份验证请求时指定用户重定向的位置 - 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 - 希望这里的评论足够:

<?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 boolean $hasCode Whether or not we have been authenticated already
     * @param string $driver Driver to use, Facebook or Google
     * @param string $type Type of call - Login, Register, or Link
     * @return array|\Illuminate\Http\RedirectResponse|\Illuminate\Routing\Redirector
     */
    public function execute($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':
                // Register using social media account
                return redirect('register')
                    ->with('social_type', $driver)
                    ->with('social_id', $id)
                    ->with('email', $email)
                    ->with('first_name', $first_name)
                    ->with('last_name', $last_name);
                break;
            case 'link':
                // Associate this Social Media account with the current User
                $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
    }
}

我倾向于在我的网址中包含提供商。例如:

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

这样我可以在我的控制器操作中访问请求中的提供者名称:

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
        }
    }
}

迟到但可以帮助其他人。如果您想处理多个重定向,如登录、注册、将社交帐户链接到用户个人资料,可以通过覆盖控制器端的服务配置来完成。

config(['services.google.redirect' => <Your New URL here> ]);
Socialite::driver('google')->redirect();

注意:- 有一些社交平台严格要求在他们的开发者控制台中提及重定向 URL。所以你需要在那里提到每个重定向 URL。
