php - 使用 HybridAuth 验证用户时无法捕获异常

Question

我正在创建一个 WordPress 插件，当有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。我为此目的使用的代码是:-

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();

    } 

如果用户在 Facebook oAuth 对话框中允许权限，此代码将完美运行，但如果用户拒绝授予权限，它会抛出一个我似乎无法捕获的异常:-

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!

在 Hybrid/Providers/Facebook.php 文件中编写的代码是:-

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() );
}

我尝试使用谷歌搜索并搜索问题，但我找不到任何问题。抱歉，我无法提供我在研究中得到的任何信息。

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 好的。但是如果我移动线 $hybridauth = new Hybrid_Auth($config);

在 try{} 区域之外，我就无法捕捉到这个异常。这很奇怪，因为这条线工作正常并且不会抛出任何异常。
