Php Facebook connect API，用户id始终为空，我可以'；我无法恢复我的个人资料

这是我在stackoverflow上的第一篇文章，我希望我能对我的问题有正确的答案，因为我到处都在研究以找到解决方案，但没有什么有用的…所以我正在做一个zend项目，在我的Facebookcontroller.php中，我使用了成功连接到我的网站并获取有关profil的信息所需的所有函数。事实上，这是我第一次使用此API，所以我选择使用php SDK。问题是我的$uid中总是有一个大“0”，所以我无法恢复我的个人资料，也无法将这些信息存储在我的数据库中……我希望这很清楚，这是我控制器的代码。关于facebook应用程序，我在www.developer.facebook.com中创建了一个，它工作正常，我可以进行身份验证，然后被重定向到我的index.php。感谢您的帮助

请删除您的appId和secret以防止不必要的访问…您使用的是什么版本的Facebook PHP SDK？感谢您的回复，我正在使用PHP SDK v3.0.0，有人能帮我吗？我需要你的帮助，我没有找到解决这个问题的方法。我想知道我的网站是否应该通过ssl认证来获取用户信息？facebook是否可能阻止对未经ssl认证的应用程序进行任何认证？
