Laravel 5.1和Socialite - 如何将Facebook / Twitter详细信息连接到当前经过身份验证的用户

Question

我已经很好地实施了社交网站，适用于与我的应用数据库中的电子邮件地址具有相同Facebook电子邮件地址的新用户或用户。

但是，某些用户将拥有与他们在我的应用中使用的帐户不同的Facebook电子邮件帐户。 我想允许用户在登录时将他们的Facebook个人资料连接到他们的应用帐户。

这是我的路线：

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

redirectToProvider代码：

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

以下是我当前处理社交网络用户创建/更新的代码：

public function handleProviderCallback($provider)
    {
        $user = Socialite::driver($provider)->user();

        $user_query = User::where('email', $user->email)
            ->orWhere('oauth_facebook_id', $user->id)
            ->orWhere('oauth_twitter_id', $user->id)
            ->get();

        if($user_query->count() > 0) {

            $the_user = $user_query->first();

            if($provider === 'facebook') {
                $the_user->oauth_facebook_id = $user->id;
            }

            if($provider === 'twitter') {
                $the_user->oauth_twitter_id = $user->id;
            }

            $the_user->avatar = $user->avatar;

            $the_user->save();

            \Auth::login($the_user, true);

            return redirect('/dashboard');
        }

        $new_user = User::create([
            'name' => $user->name,
            'email' => $user->email,
            'oauth_facebook_id' => $provider === 'facebook' ? $user->id : NULL,
            'oauth_twitter_id' => $provider === 'twitter' ? $user->id : NULL,
            'avatar' => $user->avatar,
            'confirmed' => true,
            'gender' => $user->user['gender'],
        ]);

        \Auth::login($new_user, true);

        flash()->success('Success!', 'Your account has been created using your '.ucfirst($provider).' details!');
        return redirect('/dashboard');
    }

将返回的详细信息与当前经过身份验证的用户链接的最佳方法是什么？

只需检查用户是否已登录，然后使用oauth_{provider}_id返回的数据（ $userData->id ）更新该用户的oauth_{provider}_id 。

否则，使用返回的数据创建新用户。

像这样的东西：

public function handleProviderCallback($provider)
{
    $userData = Socialite::driver($provider)->user();

    if(Auth::check()) {

        $user = User::find(Auth::user()->id);

        if($provider === 'facebook') {
            $user->oauth_facebook_id = $userData->id;
        }

        if($provider === 'twitter') {
            $user->oauth_twitter_id = $userData->id;
        }

        $user->save();

    } else {

        $new_user = User::create([
            'name' => $userData->name,
            'email' => $userData->email,
            'oauth_facebook_id' => $provider === 'facebook' ? $userData->id : NULL,
            'oauth_twitter_id' => $provider === 'twitter' ? $userData->id : NULL,
            'avatar' => $userData->avatar,
            'confirmed' => true,
            'gender' => $userData->user['gender'],
        ]);

        \Auth::login($new_user, true);

        flash()->success('Success!', 'Your account has been created using your '.ucfirst($provider).' details!');

    }

    return redirect('/dashboard');
}
