获取所有当前已知的值：

Wolfram Language code: CloudDeploy[AskFunction[ Ask[{"name", "What's your name?"} -> "String"]; Ask[{"age", "How old are you?"} -> "Number"]; AskState[] ]]

使用 AskState 检查回答的数目：

Wolfram Language code: CloudDeploy[AskFunction[Ask["x" -> "Number"];Ask["y" -> "Number"]; AskDisplay["You've entered " <> ToString[Length[AskState[]]] <> " numbers."] ]]
