Question

在DataWeaver文档10.8中。 Changing the Format of a Date https://developer.mulesoft.com/docs/dataweave#_date_time_operations

Below is the transform 

 %dw 1.0
 %output application/json
 %type mydate = :string { format: "YYYY/MM/dd" }
 ---
{
formatedDate1: |2003-10-01T23:57:59| as :mydate,
formatedDate2: |2015-07-06T08:53:15| as :mydate
}

在dataweaver预览中，它看起来很正常，符合预期的响应（更改了日期格式）。我正在文件组件中进行响应，但它没有按照提到的格式转换日期（也在dataWeaver之后保留logger，而不是预期的响应）。

回复如下

{
"formatedDate1": "2003-10-01T23:57:59",
"formatedDate2": "2015-07-06T08:53:15"
 }

我有其他查询，这里我们正在编织织布机内的日期。如果假设我们从Input参数中获取日期字段，我们需要将字段包装在||内。如下所示，是否可行

    %dw 1.0
    %output application/json
     %type mydate = :string { format: "YYYY/MM/dd" }
    ---
    {
     formatedDate1: |payload.dateField1| as :mydate,
     formatedDate2: payload.dateField1 as :mydate
    }

以上似乎对我不起作用。请告诉我正确的用法。提前致谢

Answer 1

试试这个：

%dw 1.0
%output application/json
%type mydate = :date { format: "yyyy/M/d" }
---
{
  formatedDate1: |2003-10-01T23:57:59| as :mydate,
  formatedDate2: |2015-07-06T08:53:15| as :mydate
}

输出：

{
  "formatedDate1": "2003-10-01",
  "formatedDate2": "2015-07-06"
}

区别在于从:string到:date:的数据类型：

%type mydate = **:date** { format: "yyyy/M/d" }

结果似乎没有变为/。这可能是一个错误。

Answer 2

 %dw 1.0
 %output application/json
 %type mydate = :string { format: "YYYY/M/d" }
 ---
{
formatedDate1: |2003-10-01T23:57:59| as :mydate,
formatedDate2: |2015-07-06T08:53:15| as :mydate
}
