fancybox 的这个问题让我抓狂。当您单击该链接时，加载图标会一直显示，并且不会显示任何页面。我已经测试了几件事，但我不知道为什么会发生这种情况。
它只发生在一种特定类型的页面上，它是我用来向 facebook 注册用户的页面（我在内部使用 hybridauth）。他们应该被要求在 facebook 网站上获得授权，但什么都没有。但是当然，如果你正常打开链接，没有fancybox，它就可以正常工作。
我为这个问题做了一个活生生的例子，所以你可以自由地探索它。 现场测试
我非常感谢您的帮助，如果您需要更多信息，请询问。谢谢你。
编辑：这是 register.php 源代码：
<?php
session_start();
error_reporting(E_ALL);
ini_set('display_errors', 'On');
$config = dirname(__FILE__) . '/hybridauth/hybridauth/Hybrid/config.php';
require_once( "hybridauth/hybridauth/Hybrid/Auth.php" );
try{
$hybridauth = new Hybrid_Auth( $config );
switch($_GET["s"]){
case "facebook":
$facebook = $hybridauth->authenticate( "Facebook" );
$facebook_user_profile = $facebook->getUserProfile();
echo "<pre>";
print_r( $facebook_user_profile );
echo "</pre>";
}
} catch(Exception $e){
// Display the recived error,
// to know more please refer to Exceptions handling section on the userguide
switch( $e->getCode() ){
case 0 : echo "Unspecified error."; break;
case 1 : echo "Hybriauth configuration error."; break;
case 2 : echo "Provider not properly configured."; break;
case 3 : echo "Unknown or disabled provider."; break;
case 4 : echo "Missing provider application credentials."; break;
case 5 : echo "Authentification failed. "
. "The user has canceled the authentication or the provider refused the connection.";
break;
case 6 : echo "User profile request failed. Most likely the user is not connected "
. "to the provider and he should authenticate again.";
$twitter->logout();
break;
case 7 : echo "User not connected to the provider.";
$twitter->logout();
break;
case 8 : echo "Provider does not support this feature."; break;
}
// well, basically your should not display this to the end user, just give him a hint and move on..
echo "<br /><br /><b>Original error message:</b> " . $e->getMessage();
}
