PHP :不允许序列化闭包

Question

整个场景是，我在我的opencart商店中添加了facebook登录扩展，当新用户单击登录时，使用facebook添加电子邮件和密码，然后单击登录，就会出现一个确认登录对话框，其中有两个按钮“取消”和“登录”，如果用户单击登录，它会将用户带到我的存储区，但是当用户单击“取消”时，它应该会将用户带回到我的商店的登录页面，但是它反而会给出错误的"Fatal error : uncaught exception with a message serialization of closure is not allowed。

对于这一行"$_SESSION["HA::STORE"][$key] = serialize($value);，我使用了以下函数，其中包含这一行：

public function set( $key, $value)
    {
        $key = strtolower( $key );

        $_SESSION["HA::STORE"][$key] = serialize($value);
    }

我已经尝试过这个var_dump(序列化($value))；它返回一个字符串--如何序列化这个字符串？我已经找过了，但没有找到任何有用的解决办法。

最新情况：

function login()
    {
        Hybrid_Logger::info( "Enter Hybrid_Provider_Adapter::login( {$this->id} ) " );

        if( ! $this->adapter ){
            throw new Exception( "Hybrid_Provider_Adapter::login() should not directly used." );
        }

        // clear all unneeded params
        foreach( Hybrid_Auth::$config["providers"] as $idpid => $params ){
            Hybrid_Auth::storage()->delete( "hauth_session.{$idpid}.hauth_return_to"    );
            Hybrid_Auth::storage()->delete( "hauth_session.{$idpid}.hauth_endpoint"     );
            Hybrid_Auth::storage()->delete( "hauth_session.{$idpid}.id_provider_params" );
        }

        // make a fresh start
        $this->logout();

        # get hybridauth base url
        $HYBRID_AUTH_URL_BASE = Hybrid_Auth::$config["base_url"];

        # we make use of session_id() as storage hash to identify the current user
        # using session_regenerate_id() will be a problem, but ..
        $this->params["hauth_token"] = session_id();

        # set request timestamp
        $this->params["hauth_time"]  = time();

        # for default HybridAuth endpoint url hauth_login_start_url
        #   auth.start  required  the IDp ID
        #   auth.time   optional  login request timestamp
        $this->params["login_start"] = $HYBRID_AUTH_URL_BASE . ( strpos( $HYBRID_AUTH_URL_BASE, '?' ) ? '&' : '?' ) . "hauth.start={$this->id}&hauth.time={$this->params["hauth_time"]}";

        # for default HybridAuth endpoint url hauth_login_done_url
        #   auth.done   required  the IDp ID
        $this->params["login_done"]  = $HYBRID_AUTH_URL_BASE . ( strpos( $HYBRID_AUTH_URL_BASE, '?' ) ? '&' : '?' ) . "hauth.done={$this->id}";

        Hybrid_Auth::storage()->set( "hauth_session.{$this->id}.hauth_return_to"    , $this->params["hauth_return_to"] );
        Hybrid_Auth::storage()->set( "hauth_session.{$this->id}.hauth_endpoint"     , $this->params["login_done"] ); 
        Hybrid_Auth::storage()->set( "hauth_session.{$this->id}.id_provider_params" , $this->params );

        // store config to be used by the end point 
        Hybrid_Auth::storage()->config( "CONFIG", Hybrid_Auth::$config );

        // move on
        Hybrid_Logger::debug( "Hybrid_Provider_Adapter::login( {$this->id} ), redirect the user to login_start URL." );

        Hybrid_Auth::redirect( $this->params["login_start"] );
    }

在function_login中，set()由以下代码调用：

Hybrid_Auth::storage()->set( "hauth_session.{$this->id}.hauth_return_to"    , $this->params["hauth_return_to"] );
        Hybrid_Auth::storage()->set( "hauth_session.{$this->id}.hauth_endpoint"     , $this->params["login_done"] ); 
        Hybrid_Auth::storage()->set( "hauth_session.{$this->id}.id_provider_params" , $this->params );

我猜您正在传递或被传递一个闭锁作为set()的$value参数。

您需要使用反射检查和忽略闭包。

public function set( $key, $value)
{
    if (is_object($value)) {
        try {
            $reflection = new ReflectionFunction($value);
            if ($reflection->isClosure()) {
                //Trigger a E_USER_NOTICE if you want to avoid silently failing
                trigger_error("You cannot pass a closure as the second parameter of set()");
                return; // Do nothing else
            }
        } catch (\ReflectionException $e) {
            // Catch the exception thrown if $value is not a closure
        }
    }
    $key = strtolower( $key );

    $_SESSION["HA::STORE"][$key] = serialize($value);
}

或者您可以捕获并忽略异常：

function set( $key, $value)
{
    $key = strtolower( $key );
    try{
        $_SESSION["HA::STORE"][$key] = serialize($value);
    } catch (\Exception $e) {
        // Catch the exception thrown and handle it however you want
    }
}
