Java sencha extjs GridPanel保存状态格式

我有一个场景，在这个场景中，我想将在客户端修改的extjsgridpanel的列顺序保存到服务器上。为此，我将extjs gridpanel的状态保存在cookie中。将此cookie发送到服务器端并从cookie中检索列顺序的值

我的问题是gridPanel在cookie中以哪种格式保存其列顺序。我应该如何从服务器端检索它

我在服务器端得到的键值对是这样的。那么这个值是什么样的对象呢。是JSON还是其他格式。其次，这是我实现第一段中指定场景的方法。如果你有其他更好的方法。请给我一些建议。任何帮助都将不胜感激

你为什么关心格式？你不必在意，除非你打算在服务器上修改它

只要在客户端将cookie数据发送到服务器时保存cookie数据，并在客户端加载页面时发送cookie数据即可
