Javascript 使用类型脚本将Json转换为数组Angular2 js

我有我想要转换为具有指定键的数组的json数据

[
  {"id":1,"url": "http://test.com"},
  {"id":2,"url":"https://ad.com/"},
  {"id":3,"url":"https://ad12.com/"},
  {"id":4,"url":"https://ad12.com/"}
]

代码： 我只需要url键值

Output:`["http://test.com", "http://ad.com", "http://ad12.com"]

`应该是：

http.get('', { headers: ''})
    .map(response => {
        return response.json().map(d => {
            return new class(d.url);
        });
    });

如果使用lodash，则

var urls = _.map(yourArray, 'url');

或者ES6和lodash

let urls = _.map(yourArray, 'url');

lets urls = yourArray.map((obj) => {
    return obj.url;
});

lets urls = yourArray.map(function (obj) {
    return obj.url;
});

或ES6，不含lodash

let urls = _.map(yourArray, 'url');

lets urls = yourArray.map((obj) => {
    return obj.url;
});

lets urls = yourArray.map(function (obj) {
    return obj.url;
});

或ES5，不含lodash

let urls = _.map(yourArray, 'url');

lets urls = yourArray.map((obj) => {
    return obj.url;
});

lets urls = yourArray.map(function (obj) {
    return obj.url;
});

那么，为什么不在模型中保存它并在其上应用map呢？我已经尝试过了，但无法实现。请展示您尝试过的内容。@echonax我已经尝试过上述代码。更惯用的ES6是

map（（{url}）=>url）

。
