我是Laravel开发人员。我用Laravel开发了一个电子商务插件，我只想将WordPress与Laravel结合起来。所以我需要在Laravel和WordPress之间共享或进行常见的登录会话。
我怎么能实现这个？是否有专门的插件可用于此？或者我可以使用laravel-Auth？
正确的方法是将Laravel（或Wordpress）作为Auth服务器并创建类似SSO插件。从Laravel登陆NodeBB论坛我也是如此。
我建议的步骤：
所以你有laravel（注册等）的所有用户，如果他们想登录到Wordpress，他们登录Laravel App并授予登录wordpress的权限。想想看就像你添加Facebook Login to your site更多地了解wordpress SSO
但是要使用会话和cookie，可能会出现安全问题。希望帮助。
我尝试了各种各样的东西：Laravel Passport（OAuth2），OpenID Connect等。
但是，我能够解决的唯一解决方案是将WordPress登录页面重定向到生成JWT（JSON Web令牌）的经过身份验证的Laravel路由，并重定向回WordPress上的特殊回调URL，该URL可以创建新用户或登录现有用户。
它运作良好。
class JwtController extends Controller {
/**
* Inspired by https://github.com/WebDevStudios/aad-first-party-sso-wordpress/tree/master/lib/php-jwt
*
* @param Request $request
* @return ResponseInterface
*/
public function redirectWithToken(Request $request) {
$key = config('jwt.key');
$wpJwtUrl = $request->input('callback');
$redirectUrlAfterLogin = $request->input('redirect_to'); //Get the original intended destination and append as URL param to /jwt.
$tokenArray = $this->getToken(auth()->user(), $redirectUrlAfterLogin);
$jwt = \Firebase\JWT\JWT::encode($tokenArray, $key);
$wpJwtUrlWithTokenAsParam = $wpJwtUrl . '?token=' . $jwt;
return redirect()->away($wpJwtUrlWithTokenAsParam);
}
/**
*
* @param \App\User $user
* @param string $redirectUrlAfterLogin
* @return array
*/
public function getToken($user, $redirectUrlAfterLogin) {
$now = \Carbon\Carbon::now();
$aud = config('jwt.audience'); //root URL of the WordPress site
$firstName = StrT::getFirstNameFromFullName($user->name);
$expirationMins = config('jwt.expirationMins');
$token = [
"iss" => url("/"),
"aud" => $aud, //"audience" https://tools.ietf.org/html/rfc7519#section-4.1.3
"iat" => $now->timestamp, //"issued at" https://tools.ietf.org/html/rfc7519#section-4.1.6
"exp" => $now->addMinutes($expirationMins)->timestamp, //"expiration" https://tools.ietf.org/html/rfc7519#section-4.1.4
"attributes" => [
'emailAddress' => $user->email,
'firstName' => $firstName,
'lastName' => StrT::getLastNameFromFullName($user->name),
'nickname' => $firstName,
'displayName' => $user->name,
'redirectUrlAfterLogin' => $redirectUrlAfterLogin//In plugin: use redirectUrlAfterLogin from attributes after login.
]
];
return $token;
}
}
然后编辑它的auth.php为：
// register the callback
add_action('rest_api_init', function () {
register_rest_route('jwt-auth/v1', 'callback', [
'methods' => 'GET',
'callback' => 'ja_login'
], true);
});
require_once('JWT.php');
function ja_login() {
//get all attributes
$options = get_option('ja_settings');
$token_name = $options['token_name'];
$secret_key = $options['secret_key'];
$iss = $options['iss'];
$aud = $options['aud'];
// decode the token
$token = $_GET[$token_name];
$key = $secret_key;
$JWT = new JWT;
$json = $JWT->decode($token, $key);
$jwt = json_decode($json, true);
// use unix time for comparision
$exp = is_int($jwt['exp']) ? $jwt['exp'] : strtotime($jwt['exp']);
$nbf = $jwt['nbf'] ?? null;
$now = strtotime("now");
// if authentication successful
if (($jwt['iss'] == $iss) && ($jwt['aud'] == $aud) && ($exp > $now) && ($now > $nbf)) {
return getUserFromValidToken($options, $jwt);
} else {
return 'Login failed. Please let us know exactly what happened, and we will help you out right away.';
}
}
