有没有办法根据键来映射它？

Question

有没有办法根据键（“A”、“A-BOMB”等）映射下面的 JSON 示例？基本上我希望客户输入他们想要定义的单词，然后将其存储在变量中。假设他们要查找的单词存储在 vars.word 中，有没有一种方法可以映射 dataweave，以便它可以找到它并返回任何同义词、含义、同义词等？

{
"A": {
    "ANTONYMS": [],
    "MEANINGS": {
        "6": [
            "Noun",
            "the 1st letter of the Roman alphabet",
            [
                "Letter",
                "Letter of the alphabet",
                "Alphabetic character"
            ],
            []
        ],
        "7": [
            "Noun",
            "the blood group whose red cells carry the A antigen",
            [
                "Blood group",
                "Blood type"
            ],
            []
        ]
    },
    "SYNONYMS": [
        "Ampere",
        "Type a",
        "Antiophthalmic factor",
        "Angstrom",
        "Adenine"
    ]
},
"A-BOMB": {
    "ANTONYMS": [],
    "MEANINGS": {},
    "SYNONYMS": [
        "Atomic bomb",
        "Fission bomb",
        "Plutonium bomb",
        "Atom bomb",
        "A-bomb"
    ]
},
"A-HORIZON": {
    "ANTONYMS": [],
    "MEANINGS": {
        "1": [
            "Noun",
            "the top layer of a soil profile; usually contains humus",
            [],
            []
        ]
    },
    "SYNONYMS": [
        "A-horizon",
        "A horizon"
    ]
}

我已经

尝试过 filterObject ((value, key) -> valuestartsWith vars.word)

不确定是否应该使用过滤器、查找或startsWith函数。我不知道我在做什么。这甚至可能是不可能的。我只是不知道从哪里开始

Answer 1

注意-> startsWith 或 contains 不适合这里，因为您的对象具有以 A 开头的所有键，并且您的要求是匹配整个单词。

我认为使用仅数组/对象索引会对您有所帮助

DW

%dw 2.0
output application/json
var ip= "A-BOMB"
---
payload[ip]

使用 filterObject 以及 匹配 会给你相同的结果

DW

%dw 2.0
output application/json
var ip= "A-BOMB"
---
payload filterObject ((value, key) -> key matches ip)

输出

{
  "ANTONYMS": [
    
  ],
  "MEANINGS": {
    
  },
  "SYNONYMS": [
    "Atomic bomb",
    "Fission bomb",
    "Plutonium bomb",
    "Atom bomb",
    "A-bomb"
  ]
}
