Question

有 4 个字段基于其值组合，我们必须在 Mulesoft 中过滤数据。示例：

输入载荷 1：

{
 "Msg": {
  "Code": "abc",
  "Chcode": "123",
  "Dcode": "55",
  "Type": "pqr"
 }
}

输入载荷 2：

{
 "Msg": {
   "Code": "klm",
   "Chcode": "789",
   "Dcode": "32",
   "Type": "xyz"
 }
}

输入载荷 3：

{
 "Msg": {
  "Code": "klm",
  "Chcode": "456",
  "Dcode": "22",
  "Type": "shi"
 }
}

过滤条件：输入有效载荷应与 Code、Chcode、Dcode 和 Type 匹配。
示例：输入负载应包含 Code=abc、Chcode=123、Dcode=55、Type=pqr

Code	Chcode	Dcode	Type
abc	123	55	pqr
ghl	456	22	shi
ghi	276	3u	foh

输入payload 1匹配过滤条件第一行code,Chcode,Dcode和Type相同。因此应该过滤该记录以进行处理。输入负载 3 与 Chcode、Dcode 和 Type 匹配，但与 Code 不匹配，因此忽略此记录。

像上面这些组合，共有45种组合，Mulesoft如何过滤这类记录。

Answer 1

此脚本是如何执行条件检查的示例：

%dw 2.0
output application/json
import * from dw::core::Arrays
import * from dw::core::Objects
var conditionsTable=[
    {Code: "abc", Chcode: "123", Dcode:"55", Type: "pqr"},
    {Code: "ghl", Chcode: "456", Dcode:"22", Type: "shi"},
    {Code: "ghl", Chcode: "276", Dcode:"3u", Type: "foh"}
]
fun matchRecord(record, cond)=record everyEntry (value, key) -> cond[key] == value
fun matchConditions(record, conditions)=conditions some ((item) -> matchRecord(record, item))
---
matchConditions(payload.Msg, conditionsTable)
