Question

我正在创建一个WordPress插件，当新帖子添加到网站时，该插件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。我用于此目的的代码是： -

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，此代码可以正常运行，但如果用户拒绝授予权限，则会抛出一个我无法捕获的异常： -

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。对不起，我无法提供我在研究中得到的任何信息。

Answer 1

此解决方案适用于我：

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

异常火灾好的。但如果我移动线 $ hybridauth = new Hybrid_Auth（$ config）;

在try {}区域之外

，我无法捕捉到这个例子。这是非常奇怪的，因为这行可以正常运行并且不会抛出任何异常。

Answer 2

我有同样的问题和解决方案是我忘了命名空间（我在另一个操作中），所以catch块的正确代码是：

catch(\Exception $e) {}

使用HybridAuth验证用户时无法捕获异常
