在使用HybridAuth对用户进行身份验证时无法捕获异常 - Cannot catch an Exception while authenticating user with HybridAuth

Cannot catch an Exception while authenticating user with HybridAuth

我正在创建一个WordPress插件，当新帖子添加到网站时，它会自动将帖子发布到Facebook。出于同样的原因，用户需要验证他的Facebook帐户。我为此使用的代码是:-

try {
        $fp_hybridauth  = new Hybrid_Auth( $hybrid_config );
        $fp_hybridauth->authenticate( "facebook" ); //this function does the job of authenticating user and it is causing the exception to be thrown 
        update_option( "session_data", $fp_hybridauth->getSessionData() );
        wp_redirect( site_url("/wp-admin/admin.php?page=facebook-publish&tab=api&fbauth=success") );
    }
    catch( Exception $e ){
        echo $e->getMessage();
    }

如果用户允许Facebook oAuth对话框中的权限，这段代码可以完美地工作，但如果用户拒绝给予权限，它会抛出一个异常，我似乎无法捕获:-

Fatal error: Uncaught exception 'Exception' with message 'Authentication failed! The user denied your request.' in /home/pramodjodhani/public_html/dev/wp-content/plugins/facebook-publish/lib/class/hybridauth/Hybrid/Providers/Facebook.php:86 Stack trace: #0 /home/pramodjodhani/public_html/dev/wp-content/plugins/facebook-publish/lib/class/hybridauth/Hybrid/Endpoint.php(182): Hybrid_Providers_Facebook->loginFinish() #1 /home/pramodjodhani/public_html/dev/wp-content/plugins/facebook-publish/lib/class/hybridauth/Hybrid/Endpoint.php(58): Hybrid_Endpoint::processAuthDone() #2 /home/pramodjodhani/public_html/dev/wp-content/plugins/facebook-publish/lib/class/hybridauth/index.php(15): Hybrid_Endpoint::process() #3 {main} Next exception 'Exception' with message 'Authentication failed!

Hybrid/Providers/Facebook.php文件中的代码是:-

function loginFinish()
{ 
    // in case we get error_reason=user_denied&error=access_denied
    if ( isset( $_REQUEST['error'] ) && $_REQUEST['error'] == "access_denied" ){ 
        throw new Exception( "Authentication failed! The user denied your request.", 5 ); //THIS IS LINE NUMBER 86 
    }
    // try to get the UID of the connected user from fb, should be > 0 
    if ( ! $this->api->getUser() ){
        throw new Exception( "Authentication failed! {$this->providerId} returned an invalid user id.", 5 );
    }
    // set user as logged in
    $this->setUserConnected();
    // store facebook access token 
    $this->token( "access_token", $this->api->getAccessToken() );
}

我试着用谷歌搜索这个问题，但我找不到任何问题。抱歉，我不能提供我在研究中得到的任何东西。

这个解决方案适合我:

try{
    $hybridauth = new Hybrid_Auth($config);
    $adapter = $hybridauth->authenticate($service);
}catch(Exception $ex){
    var_dump($ex);
    return;
}
$user_profile = $adapter->getUserProfile();

异常触发Ok。但是如果我移动这条线$hybridauth = new Hybrid_Auth($config);

在try{}区域之外，那么我无法捕获此异常。这很奇怪，因为这一行运行正常，没有抛出任何异常。

我有同样的问题和解决方案是我忘记了名称空间(我在另一个名称空间内操作)，所以catch块的正确代码是:

catch('Exception $e) {}
