SilverStripe 4-注销时空白页 [英] SilverStripe 4 - Blank page on logging out
问题描述
正如我在此处所述，我将允许预先生成的用户使用默认的from来从SilverStripe 4网站的前端页面注销.由于登录有效而注销.
As I stated here, I would allow pre-generated users to log out from a SilverStripe 4 website front-end page, by using the default from. Logging out because log in works.
问题是，如果登录的一般用户尝试通过单击诸如Security/logout(以及Security/logout?BackURL=home/)之类的链接注销，则该用户将被重定向到空白页(仅显示页眉/页脚，如下所示)默认的Page.ss已实现).显然，控制器无法正常工作或类似，因为URL仅将我指向Security/logout，而没有后续重定向.此外，该会话没有被清除，如果我返回到用户仪表板页面，其结果仍将登录.
The problem is that if a logged generic user tries to log out by clicking on a link like Security/logout (as well as Security/logout?BackURL=home/), it being redirected to a blank page (just with header/footer visible, as the default Page.ss is implemented). Apparently the controller doesn't work or similar, because URL points me simply to Security/logout with no following redirects. Furthermore, the session is not being cleared and if I go back to the user dashboard page, it results still logged in.
因此，我尝试实现自定义身份验证器，就像我在SS 3中通常所做的那样，但是我注意到了一些小差异.然后，我同时遵循了官方文档和建议的示例以寻求帮助.
So, I tried to implement a custom authenticator, as I usually do in SS 3, but I noticed some little differences. Then, I followed both the official doc and the suggested example for help.
这种情况:
MemberAuthenticator自定义类 (在 MySite/code 中)
<?php
// Definizione Namespace
namespace Greylab\Corporate\Authenticator\UtenteAuthenticator;
use SilverStripe\Security\MemberAuthenticator\MemberAuthenticator;
/**
* Classe Autenticazione Utente
*/
class UtenteAuthenticator extends MemberAuthenticator
{
/**
* Login Paziente - Getter
* @param string $link URL di autenteicazione utente
* @return object Form di autenticazione utente
*/
public function getLoginHandler($link)
{
return UtenteLoginHandler::create($link, $this);
}
/**
* Logout Paziente - Getter
* @param string $link URL di deautenteicazione utente
* @return object Form di deautenteicazione utente
*/
public function getLogoutHandler($link)
{
return UtenteLogoutHandler::create($link, $this);
}
}
MemberAuthenticator \ LoginHandler自定义类 (在 MySite/code 中)
<?php
// Definizione Namespace
use SilverStripe\Security\MemberAuthenticator\LoginHandler;
use SilverStripe\Core\Injector\Injector;
/**
* Clesse Login Utente
*/
class UtenteLoginHandler extends LoginHandler
{
/**
* Metodo gestione Login Utente
* Setter
* @param array $dati Dati form login
* @param object $form Form login
* @return void
*/
public function doLogin($dati, $form)
{
$utente = $this->checkLogin($dati);
// Controllo Utente
if ($utente) {
$request = Injector::inst()->get(HTTPRequest::class);
$session = $request->getSession();
$cliente = $session->set('UtenteLoginHandler.MemberID', $utente->ID);
$profiloPaziente = Member::get()->byID($session->get('UtenteLoginHandler.MemberID'));
$datiPaziente = $session->set('UtenteLoginHandler.Data', $dati);
// Controllo Utente
if ($profiloCliente) {
$this->performLogin($profiloCliente, $datiCliente);
return $this->redirectAfterSuccessfulLogin();
} else {
// Se utente invalido torna al form
return $this->redirectBack();
}
} else {
// Se utente invalido torna al form
return $this->redirectBack();
}
}
}
MemberAuthenticator \ LogoutHandler自定义类 (在 MySite/code 中)
// Definizione Namespace
use SilverStripe\Security\MemberAuthenticator\LogoutHandler;
use SilverStripe\Core\Injector\Injector;
use SilverStripe\Security\Security;
use SilverStripe\Security\IdentityStore;
use SilverStripe\Security\Member;
use SilverStripe\Control\HTTPResponse;
/**
* Clesse Login Utente
*/
class UtenteLogoutHandler extends LogoutHandler
{
/**
* Metodo gestione Logout Utente
* Setter
* @param array $dati Dati form login
* @param object $form Form login
* @return HTTPResponse
*/
public function doLogOut($utente)
{
// Controllo Utente
if ($utente) {
$request = Injector::inst()->get(HTTPRequest::class);
$session = $request->getSession();
$paziente = $session->get('UtenteLoginHandler.MemberID');
$datiPaziente = $session->get('UtenteLoginHandler.Data');
// Controllo Sessione Utente
if ($paziente && $datiPaziente) {
$session->clear('UtenteLoginHandler.MemberID');
$session->clear('UtenteLoginHandler.Data');
Security::setCurrentUser(null);
return $this->redirectAfterLogout();
// Tried with this approach too without success...
/* if ($utente instanceof Member) {
Injector::inst()->get(IdentityStore::class)->logOut($this->getRequest());
return $this->redirectAfterLogout();
} */
} else {
// Se sessione utente invalida torna al form
return $this->redirectBack();
}
}
}
会员身份验证器注入 (在_MySite/ config/mysite.yml 中)
MemberAuthenticator Injection (in _MySite/config/mysite.yml)
SilverStripe\Core\Injector\Injector:
SilverStripe\Security\Security:
properties:
Authenticators:
UtenteAuthenticator: %$Greylab\Corporate\Authenticator\UtenteAuthenticator
通过此实现，什么都没有改变.
With this implementation, nothing changed.
有人可以建议我正确的方法吗?
Anyone can suggest me the right way?
提前感谢大家.
推荐答案
经过深入研究，该解决方案来自一位勇敢的正式Slack社区成员:特别感谢@
After a deep research, solution came from a brave official Slack Community member: special thanks to @kinglozzer for it.
简单来说，SS 4提供了一个全新的$LogoutURL默认参数来获取正确的注销URL.它包括登录成员SecurityID作为参数.旧的SS 3 Security/logout不足以运行该过程.因此，通过使用:
Simply, SS 4 provides a brand new $LogoutURL default parameter to obtain the right logout url. It includes the logged-in member SecurityID as parameter. The old SS 3 Security/logout isn't enough anymore to run the process. So, by using:
{$LogoutURL}&BackURL=<url>
用户将被注销并正确重定向.
User will be logged out and redirected correctly.
感谢任何人的帮助.
