javascript - 使用 TypeScript/JS/RxJS/map/reduce/filter 等将嵌套 JSON 转换为平面 JSON，

Question

如果可能的话，如何使用现有的 JS 库(RxJS for Observables、Lodash/Underscore/whatever)进行转换(无需复杂的 foreach 循环)

以下结构:

{
    "result": [
        {
            "content": {
                "resources": [
                    {
                        "prop": [
                            {
                                "key": "BAR",
                                "value": "Bar getting better"
                            },
                            {
                                "key": "FOO",
                                "value": "Foo is cool"
                            }
                        ]
                    }
                ]
            }
        }
    ]
}

很容易进入这个吗？

{
    "BAR": "Bar getting better",
    "FOO": "Foo is cool"
}

Answer 1

在 Lodash 中，使用 _.keyBy然后_.mapValues

var data = {"result":[{"content":{"resources":[{"prop":[{"key":"BAR","value":"Bar getting better"},{"key":"FOO","value":"Foo is cool"}]}]}}]},
    input = data.result[0].content.resources[0].prop;

var result = _.mapValues(_.keyBy(input, 'key'), 'value');

console.log(result);
