我最近刚刚从cakephp 1.3升级到2.06。但是，当我尝试访问控制器中的表单数据时，数据的散列方式如下：
2015-10-15 08:43:57 Error: CakeRequest Object
(
[params] => Array
(
[plugin] =>
[controller] => custom_users
[action] => ajax_login
[named] => Array
(
)
[pass] => Array
(
)
[isAjax] => 1
)
[data] => e1fe8b4c1724c30148e306708f27b30909f23d45
我检查了表格是否在前端正确形成。 文档表明我应该能够以这种方式访问我的数据，但由于某种原因，这种行为正在发生。有什么想法吗？
我添加了我在尝试提交表单时获得的跟踪：
