如何在mule3中验证Given日期不是Future日期

Question

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.

Answer 1

您也可以使用相等运算符将它们作为日期进行比较。。如果你的约会对象有时间，一定要把事情转换成一个共同的时区来处理这些边缘情况。

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)

Answer 2

1.通过#[server.dateTime]获取当前日期。

2.设置"转换"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."/>

希望它的帮助。

替代建议

%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"
