我不想添加此技巧来更改保存时的大小写，但是 有更好的方法来处理这种情况.

I dont want to add this hack to change the case when saving but is there a better way to handle this scenario.

否，如果希望以后可以使用JSON序列化程序(例如Newtonsoft JSON)反序列化，则保存时必须产生有效的JSON.因此，修正保存的路由是正确的方法.

No, you have to produce valid JSON when saving if you want to be able to later deserialize it with a JSON serializer such as Newtonsoft JSON. So fixing your saving routing is the right way to go here.
