【问题描述】：

我的要求是验证给定日期不应该是未来日期。

例如today date is 01/01/2020。

输入日期：

30/01/2020

输出：

Date should not be Future date.

【解决方案1】：

您也可以使用相等运算符将它们作为日期进行比较。如果您的日期有时间，请确保您为这些边缘情况将事物转换为公共时区。

对于骡子 3：

%dw 1.0
%input payload application/json
%output application/json
%function isFutureDate(dt) (dt as :date) > (now as :date)

%var dt = "30/01/2020" as :date { format: "dd/MM/yyyy" }
---
isFuture: isFutureDate(dt)

对于骡子 4：

%dw 2.0
output application/json
fun isFutureDate(dateToTest: Date | DateTime) =
    (dateToTest as Date) > (now() as Date)

var date = |2021-06-10|
---
isFutureDate(date)

【解决方案2】：

1.通过#[server.dateTime]获取当前日期。

2.设置Transform消息。

"datevalidation": (payload.DateOfBirth as :date {format:"yyyy-MM-dd"}) < (flowVars.currentdate as :date {format:"yyyy-MM-dd"}

3.添加验证组件isTure。

<validation:is-true config-ref="Validation_Configuration" expression="#[payload.datevalidation]" doc:name="Validation" message="date should not be Future."/>

另一个建议

%dw 2.0
output application/json
var inpDate = "08/06/2021" as Date {"format": "dd/MM/yyyy"}
var today= now() as Date {"format": "dd/MM/yyyy"} 
---
if (daysBetween(inpDate,today) > 0) "PastDate" else "FutureDate"
