如何在打字稿中创建包含多个键值对的对象数组

Question

我从服务器收到的响应如下图所示：

[
    {_from: "A/1", _to: "A/2", status:"ok"},
    {_from: "A/2", _to: "A/3", status:"ok"},
    {_from: "A/1", _to: "A/3", status:"ok"}
]

我想将其转换为数组，如下所示，在 Typescript 中：

[
    {from: 1, to: 2},
    {from: 2, to: 3},
    {from: 1, to: 3}
]

我是TypeScript的新手，对键值对的概念感到困惑。对此，我们将给予任何帮助。谢谢！

这是使用JavaScript / TypeScript的Array.map()的方法。您可以遍历数组，拆分值，然后返回所需的对象。

const a = [{_from: "A/1", _to: "A/2", status:"ok"},
{_from: "A/2", _to: "A/3", status:"ok"},
{_from: "A/1", _to: "A/3", status:"ok"}];

const res = a.map(({_from, _to}) => ({
  from: (_from.split('/'))[1],
  to: (_to.split('/'))[1],
}));

console.log(res);
