[英]Mule issue mapping payload dataweave 2.0
I am trying to map the below json payload to only show dates with "999" value.我正在尝试 map 下面的 json 有效负载仅显示具有“999”值的日期。 Below is my payload下面是我的有效载荷
[
{
"Delivery Date": "16",
"17/01/2018": "0",
"18/01/2018": "999",
"19/01/2018": "999",
"20/01/2018": "0",
"29/01/2018": "999",
"18/02/2018": "0",
"19/02/2018": "999",
"20/02/2018": "999",
"03/03/2018": "999"
}
]
And my desired output is而我想要的 output 是
{
"available_date": [
"18/01/2018",
"19/01/2018,
"29/01/2018",
"19/02/2018",
"20/02/2018",
"03/03/2018"
],
"message": ""
}
Thanks for any advice!感谢您的任何建议!
I have tried this.我试过这个。
Approach 1 MapObject ,Pluck方法 1 MapObject ,Pluck
%dw 2.0
output application/json
---
{
"available_date":
(payload mapObject ((value, key, index) -> ((key): (value)) if (value == "999")) pluck $$),
"message":""
}
Approach 2 FilterObject , keysOf方法 2 FilterObject , keysOf
%dw 2.0
output application/json
---
{
"available_date": keysOf(payload filterObject ((value, key) -> value == "999")),
"message":""
}
Output Output
{
"available_date": [
"18/01/2018",
"19/01/2018",
"29/01/2018",
"19/02/2018",
"20/02/2018",
"03/03/2018"
],
"message": ""
}
Alternative using filterObject
and keysOf
:使用filterObject
和keysOf
替代方法:
%dw 2.0
output application/json
---
{
'available_date' : keysOf(payload filterObject ((value, key, index) -> value contains "999")),
message: ""
}
The other solutions are good.其他解决方案都很好。 Just for completeness I'll contribute one using filterObject() then pluck().为了完整起见,我将使用 filterObject() 然后 pluck() 贡献一个。
%dw 2.0
output application/json
---
{
available_date: payload
filterObject ($ == "999")
pluck ((value, key, index) -> key),
message: ""
}
