在dataweave 2.0中使用enum映射数据

{
  "colors": ["RED", "GREEN", "BLUE"]
}

%dw 2.0
output application/json

var colorsEnum = {
  RED: "红色",
  GREEN: "绿色",
  BLUE: "蓝色"
}

---
colors: payload.colors map ((color) -> colorsEnum[color])

{
  "colors": ["红色", "绿色", "蓝色"]
}

%dw 2.0
output application/json

var colorsEnum = {
  RED: "红色",
  GREEN: "绿色",
  BLUE: "蓝色"
}

---
colors: payload.colors map ((color) -> if (colorsEnum[color]) colorsEnum[color] else "未知颜色")

%dw 2.0
output application/json

var colorsEnum: { (color: String) -> String } = {
  RED: "红色",
  GREEN: "绿色",
  BLUE: "蓝色"
}

---
colors: payload.colors map ((color) -> colorsEnum(color))
