我在Laravel 5.8项目中建立了2FA库。我想要做的是，当用户在2FA的刀片模板页面中键入两个因素的身份验证代码时，仅显示错误消息。我的代码块如下：
google2fa.php
<?php
return [
/*
* Auth container binding
*/
'enabled' => true,
/*
* Lifetime in minutes.
* In case you need your users to be asked for a new one time passwords from time to time.
*/
'lifetime' => 0, // 0 = eternal
/*
* Renew lifetime at every new request.
*/
'keep_alive' => true,
/*
* Auth container binding
*/
'auth' => 'auth',
/*
* 2FA verified session var
*/
'session_var' => 'google2fa',
/*
* One Time Password request input name
*/
'otp_input' => 'one_time_password',
/*
* One Time Password Window
*/
'window' => 1,
/*
* Forbid user to reuse One Time Passwords.
*/
'forbid_old_passwords' => false,
/*
* User's table column for google2fa secret
*/
'otp_secret_column' => 'google2fa_secret',
/*
* One Time Password View
*/
'view' => 'production.account.google2fa',
/*
* One Time Password error message
*/
'error_messages' => [
'wrong_otp' => "The 'One Time Password' typed was wrong.",
],
/*
* Throw exceptions or just fire events?
*/
'throw_exceptions' => true,
];
和我的google2fa.blade.php文件：

我不知道原因，但是无论是会话还是cookie都不会出错。任何帮助都将非常不错。
使用此程序包sonata-project / GoogleAuthenticator
链接：https://github.com/sonata-project/GoogleAuthenticator/blob/2.x/sample/example.php
示例代码：
include_once __DIR__.'/../src/GoogleQrUrl.php';
$secret = 'XVQ2UIGO75XRUKJO';
$code = '846474';
$g = new \Sonata\GoogleAuthenticator\GoogleAuthenticator();
echo 'Current Code is: ';
echo $g->getCode($secret);
echo "\n";
echo "Check if $code is valid: ";
if ($g->checkCode($secret, $code)) {
echo "YES \n";
} else {
echo "NO \n";
}
$secret = $g->generateSecret();
echo "Get a new Secret: $secret \n";
echo "The QR Code for this secret (to scan with the Google Authenticator App: \n";
echo \Sonata\GoogleAuthenticator\GoogleQrUrl::generate('chregu', $secret, 'GoogleAuthenticatorExample');
echo "\n";
